'''''PT-109''''' was an {{convert|80|ft|m|adj=on}} [[Electric Launch Company|Elco]] [[PT boat]] (patrol torpedo boat) last commanded by [[Lieutenant (junior grade)]] [[John F. Kennedy]], future [[United States president]], in the [[Solomon Islands campaign]] of the [[Pacific Ocean theater of World War II|Pacific theater]] during [[World War&nbsp;II]]. Kennedy's actions in saving his surviving crew after ''PT-109'' was rammed and sunk by a Japanese destroyer earned him several commendations and made him a war hero. Back problems stemming from the incident required months of hospitalization at [[Chelsea Naval Hospital]] and plagued him the rest of his life.  Kennedy's postwar campaigns for elected office often referred to his service on ''PT-109''.

==Specifications==
Hubert Scott-Paine of the British Power Boat Company had developed Air Sea Rescue fast motor boats in the UK. He took his PT boat to Elco in 1939, as there was a shortage of suitable engines in the UK at the outbreak of war. British Powerboat Company continued production of his designs in Britain throughout the hostilities. The seakeeping qualities of boats and ease of construction matched to the available Packard engines made a perfect combination.

''PT-109'' was an {{convert|80|ft|m|0|abbr=on}}, 40-ton [[Electric Launch Company|Elco]] [[motor torpedo boat]] (MTB), one of hundreds built by the firm between 1942 and 1945 in [[Bayonne, New Jersey]].

The seventh MTB of the  ''PT-103'' class, her keel was laid {{nowrap|4 March}} 1942, she was launched on {{nowrap|20 June}}, and delivered to the Navy on {{nowrap|10 July}} 1942 to be fitted out in the [[New York Naval Shipyard]] in [[Brooklyn]]. Fully loaded, she displaced {{nowrap|56 tons}} and could accommodate a crew of three officers and 14 enlisted men, with the typical crew size between 12 and 14.

The {{convert|80|ft|m|0|abbr=on|adj=on}} Elco MTBs were the largest PT boats operated by the [[U.S. Navy]] during World War&nbsp;II. They had strong wooden hulls, constructed of two layers of {{convert|1|in|cm|adj=on}} mahogany planking, excellent for speed and reasonably adequate for seakeeping, but providing limited protection in combat.

===Engines===
[[File:Tankroom2.jpeg|upright=1|thumb|left|PT tankroom below deck, looking forward, shows partially exposed fuel tank through open door in bulkhead on left.]]

''PT-109'' was powered by three 12-cylinder {{convert|1500|hp|kW}} [[Packard 1A-2500#Variants|Packard 4M-2500]] marinized aero gasoline engines (one per propeller shaft), with a designed top speed of {{convert|41|kn|lk=in}}.<ref>[http://stratton.greenms.com/pt/pt127.html PT Boat 127<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20080118111457/http://stratton.greenms.com/pt/pt127.html |date=18 January 2008 }}.</ref>

To accommodate three engines in the boat's narrow beam (and improve weight distribution), they were staggered fore-and-aft, with the two outboard motors mounted with their output shafts facing forward and power transmitted through [[V-drive]] gearboxes to their respective propeller shafts.  The center engine was mounted forward of the outboard pair in a conventional orientation, with power transmitted directly from its output end to an extended propeller shaft.<ref>''American PT Boats in World War&nbsp;II'' by Victor Chun</ref>

The engines were fitted with mufflers on the [[Transom (nautical)|transom]], both to mask the engines' noise from the enemy and to improve the crew's chance of hearing enemy aircraft. These directed the exhaust underwater at idle and extremely low speeds and were bypassed for anything faster.<ref name="DANFS">{{cite web |date=13 September 2002 |title=PT-109 |work=[[Dictionary of American Naval Fighting Ships]] (DANFS) |publisher=USN [[Naval History & Heritage Command]] |url=http://www.history.navy.mil/danfs/p/PT-109.htm |archive-url=https://web.archive.org/web/20021022173951/http://www.history.navy.mil/danfs/p/PT-109.htm |url-status=dead |archive-date=22 October 2002 |access-date=2 January 2012}}</ref>

===Armament===
[[File:PT-109 Design1943.jpeg|upright=1.4|thumb|left|''PT-109'' armament in August 1943; a forward 37 mm antitank gun, aft 20 mm autocannon, two twin .50 caliber machine gun turrets and four torpedo tubes]]

The PT boat's principal offensive weapon was its torpedoes. She was fitted with four {{convert|21|in|cm|adj=on}} [[torpedo tube]]s containing [[Mark 8 torpedo|{{nowrap|Mark 8}}]] torpedoes. They weighed {{convert|3150|lb|kg}} each, with {{convert|386|lb|adj=on}} warheads and gave the tiny boat a punch believed at the time to be effective even against armored ships. The Mark 8, however, was both inaccurate and ineffective until its detonator was recalibrated by the Navy at the end of the war. A major issue was that in the unlikely instance that they hit their target, they rarely detonated, even when they hit at a 90-degree angle to their target. Also noteworthy was that the torpedoes were slow, traveling at only {{convert|28|kn}}, and were unable to catch faster-moving Japanese vessels.{{sfn|Logevall|2020|p=335}} In contrast, the Japanese Type 93 destroyer torpedo, later called the "Long Lance", was faster at {{convert|45|kn}}, had an accurate range of {{convert|20000|yd|m}}, was far more powerful with {{convert|1000|lb|kg}} of high explosives, and unlike the Mark 8, its detonator usually worked when it hit a target.{{sfn|Doyle|2015|pp=56–57}}

One naval officer explained that 90% of the time, when the button was pushed on the torpedo tube to launch a torpedo, nothing happened, or occasionally the motor spun the propeller until the torpedo motor exploded in the tube, showering the deck with metal fragments.  For safety, a [[torpedoman's mate]] was frequently required to hit the torpedo's firing pin with a hammer to get one to launch.  Kennedy and contemporary writers noted that torpedo mates and other PT crew were inadequately trained in aiming and firing the Mark 8 torpedoes, and were never informed of the torpedoes' ineffectiveness and low rate of detonation.{{sfn|Doyle|2015|pp=32–172, 50–57}}

''PT-109'' had a single [[Oerlikon 20 mm cannon|{{nowrap|20 mm}}]] [[Oerlikon Contraves|Oerlikon]] anti-aircraft mount at the rear with "109" painted on the mounting base, two open circular rotating turrets mounting twin [[M2 Browning machine gun|M2 .50 caliber]] {{nowrap|(12.7 mm)}} anti-aircraft machine guns at opposite corners of the open cockpit, and a smoke generator on the transom, operated as needed when engaging the enemy at close range.  The boat's guns were used both offensively and defensively.

Seeking to augment the boat's firepower (given the inaccuracy and unreliability of its torpedoes), the day before her final mission, Kennedy had the ''PT-109''{{'}}s crew lash a U.S. Army [[37 mm Gun M3|37 mm antitank gun]] he had bartered for to the [[forecastle|foredeck]], replacing a small, two-man life raft. Timbers used to secure the weapon to the deck later helped save their lives when used as a float while swimming over three miles to safety on an uninhabited island.<ref name="Scale Craft">{{cite web |title=Scalecraft history |publisher=Scalecraft.com |url=http://www.scalecraft.com/index.asp?PageAction=VIEWPROD&ProdID=908 |access-date=22 February 2012 |url-status=dead |archive-url=https://web.archive.org/web/20090828030312/http://www.scalecraft.com/index.asp?PageAction=VIEWPROD&ProdID=908 |archive-date=28 August 2009}}</ref>{{sfn|Doyle|2015|pp=56–57}}

Ahead of the torpedoes on ''PT-109'' were two [[depth charge]]s, omitted on most PTs, one on each side, about the same diameter and directly in front of the launchers.  Though designed to be used against submarines, they were sometimes used to confuse and discourage pursuing destroyers. With Kennedy's squadron commander, Lt. Alvin Cluster, at the wheel in storm conditions, ''PT-109''{{'s}} port {{nowrap|Mark 6}} depth charge was knocked through the foredeck unexpectedly by an inadvertent launch of the port forward torpedo.  Cluster had asked Kennedy for a turn at ''PT 109''{{'}}s wheel, as he had only had experience with the older, Elco {{convert|77|ft|m|adj=on}} PTs. The torpedo stayed in the tube, half in and half out on a ''hot run'', its propellers spinning, until Kennedy's executive officer, Ensign Leonard Thom, deactivated it. ''PT-109'' returned to Tulagi for repairs to the foredeck and the replacement of the depth charge.

PT-''109'' was not equipped with radar.{{sfn|Doyle|2015|pp=32–172, 50–57}}

==Early operations==
[[File:PT-109.jpg|thumb|''PT-109'' entering [[Tulagi]] carrying 94 survivors from the sunken heavy cruiser [[USS Northampton (CA-26)|USS ''Northampton'']]]]
''PT-109'' was transported from the [[Norfolk Navy Yard]] to the South Pacific in August 1942 on board the [[Liberty ship]] [[SS Joseph Stanton|SS ''Joseph Stanton'']].  Originally Navy grey, it is believed the ship was painted a flat, dark green at [[Nouméa, New Caledonia]] after being offloaded.  She arrived in the [[Solomon Islands]] in late 1942 and was assigned to [[Motor Torpedo Boat Squadron 2]] based on [[Tulagi]] island.  She participated in combat operations around [[Guadalcanal]] from {{nowrap|7 December}} 1942 to {{nowrap|2 February}} 1943, when the Japanese withdrew from the island.

===Kennedy's training in motor torpedo boats===
Despite having a chronically bad back and a history of other illnesses, including abdominal pain and scarlet fever as an infant, John F. Kennedy used his father's [[Joseph P. Kennedy]] influence to get into the war. In 1940, the U.S. Army's Officer Candidate School had rejected him as 4-F, for his bad back, ulcers, and asthma.  Kennedy's father persuaded his old friend Captain Allan Goodrich Kirk, USN, head of the Office of Naval Intelligence, to let a private Boston physician certify his son's good health.<ref>Private doctor certified health in, Fleming, Thomas, "War of Revenge", Spring 2011, ''MHQ: The Quarterly Journal of Military History'', p. 16.</ref> Kennedy started in October 1941 before Pearl Harbor as an [[Ensign (rank)|ensign]] with a desk job for the [[Office of Naval Intelligence]].  He was reassigned to South Carolina in January 1942 because of his affair with Danish journalist [[Inga Arvad]].{{sfn|Dallek|2003|pp=83–84}} On 27 July 1942, Kennedy entered the Naval Reserve Officers Training School in Chicago.

[[File:Lieutenant J. D. Bulkeley k13927.jpg|thumb|right|upright|[[John D. Bulkeley|Lieutenant John D. Bulkeley]], 1941]]

After completing his Naval Reserve Officers' Training on {{nowrap|27 September}}, Kennedy voluntarily entered the [[Motor Torpedo Boat Squadrons Training Center]] in Melville, Rhode Island, where he was promoted to [[lieutenant (junior grade)]] (LTJG). In September 1942, Joseph Kennedy had secured PT Lieutenant Commander John Bulkeley's help in placing his son in the PT boat's service and enrolling him in their training school, after meeting with Bulkeley in a New York Plaza suite near his office at Rockefeller Plaza.<ref>Met at Rockefeller Plaza in {{harvnb|Doyle|2015|pp=28–31}}</ref> Nonetheless, Bulkeley would not have recommended John Kennedy for PT boat training if he did not believe he was qualified to be a PT captain. In an interview with Kennedy, Bulkeley was impressed with his appearance, communication skills, grades at Harvard, and awards received in small boat competitions, particularly while a member of Harvard's sailing team.  Exaggerated claims by Bulkeley about the effectiveness of the PTs in combat against larger craft allowed him to recruit top talent, raise war bonds, and cause overconfidence among squadron commanders who continued to pit PTs against larger craft.  But many in the Navy knew the truth; his claims that PTs had sunk a Japanese cruiser, a troopship, and a plane tender in the Philippines were false.<ref>False claims in Fleming, Thomas, "War of Revenge", Spring 2011, ''MHQ: The Quarterly Journal of Military History'', p. 17.</ref><ref>Bulkeley was involved in {{harv|Doyle|2015|pp= 25–31}}</ref> Kennedy completed his PT training in Rhode Island on {{nowrap|2 December}}, with very high marks and was asked to stay for a brief period as an instructor. He was then ordered to the training squadron, Motor Torpedo {{nowrap|Squadron 4}}, to take over the command of motor torpedo boat ''PT-101'', a {{convert|78|ft|m|adj=on}} [[PT boat#Huckins Yacht Corporation|Huckins PT boat]].

====Kennedy's transfer to the Pacific====
In January 1943, ''PT-101'' and four other boats were ordered to Motor Torpedo Boat {{nowrap|Squadron 14}} (RON 14), which was assigned to patrol the [[Panama Canal]].<ref name="Naval History">[http://www.history.navy.mil/faqs/faq60-2.htm Department of the Navy – Naval History & Heritage Command: Lieutenant John F. Kennedy, USN FAQ] {{Webarchive|url=https://web.archive.org/web/20070912113627/http://www.history.navy.mil/faqs/faq60-2.htm |date=12 September 2007 }} Retrieved 19 June 2011</ref> Kennedy detached from {{nowrap|RON 14}} in February 1943, while the squadron was in Jacksonville, Florida, preparing for transfer to the Panama Canal Zone. Still desperately seeking a combat assignment, and on his own volition, Lieutenant Kennedy then contacted family friend and crony, Massachusetts [[United States Senate|Senator]] [[David I. Walsh]], Chairman of the [[United States Senate Committee on Armed Services|Naval Affairs Committee]], who diverted his assignment to Panama, and had him sent to PT combat in the [[Solomon Islands]], granting Kennedy's previous "change-of-assignment" request to be sent to a squadron in the South Pacific.  His actions were against the wishes of his father, who had wanted a safer assignment.<ref>Walsh was involved in Kennedy's transfer to Pacific combat in {{harvnb|Doyle|2015|pp=33–34}}</ref>

The Allies had been in a campaign of [[Leapfrogging (strategy)|island hopping]] since securing Guadalcanal in a bloody battle in early 1943. Kennedy transferred on {{nowrap|23 February}} 1943, as a replacement officer to Motor Torpedo Boat {{nowrap|Squadron 2}}, which was based at [[Tulagi]] Island, immediately north of [[Guadalcanal]] in the Solomon Islands. Traveling to the Pacific on the large troop carrier {{USS| Rochambeau|AP-63|2}}, Kennedy witnessed a fierce air strike that killed the ship's captain, and found Kennedy helping to hand shells to supply a large gun on board, giving him his first taste of battle.{{sfn|Dallek|2003|pp=90–91}}  He arrived at Tulagi on {{nowrap|14 April}} and took command of ''PT-109'' on {{nowrap|23 April}}. Although ''PT-109'' was less than a year old, it had seen heavy combat service since its arrival in the Pacific, and considerable repairs were required on the boat; leading by example, Kennedy pitched in to help the crew get his vessel seaworthy.  On {{nowrap|30 May}}, several PT boats of MTBRON 2, including ''PT-109'', were ordered to the [[Russell Islands]] in preparation for the invasion of [[New Georgia]].<ref name="Naval History" />

After the capture of [[Rendova Island]], the PT boat operations were moved north to a crude "bush" berth there on {{nowrap|16 June}}.<ref name="DANFS" /> The Rendova base held the potential for its residents to contract a host of unpleasant diseases like [[malaria]], [[dengue]], [[dysentery]], and [[elephantiasis]]. The Navy men stationed there also contended with cockroaches, rats, foot diseases, ear fungus, and mild malnutrition from the monotonous and mostly canned food.  On his first desk assignment with the Navy after his return to the States, Kennedy suffered from the aftereffects of malaria, [[colitis]], and chronic back pain, all caused or aggravated by his experiences in combat or during his stay at the Rendova base.<ref name="Keresey">{{cite web |title=Dick Keresey, 'Farthest Forward' |publisher=American Heritage Magazine |url=http://www.americanheritage.com/articles/magazine/ah/1998/4/1998_4_60.shtml |access-date=14 June 2018 |archive-url=https://web.archive.org/web/20080218142719/http://www.americanheritage.com/articles/magazine/ah/1998/4/1998_4_60.shtml |archive-date=18 February 2008}}</ref>

From their crude base on the northern tip of Rendova Island, on a small spit of land known as Lumbari, PT boats conducted daring and dangerous nightly operations, both to disturb the heavy Japanese barge traffic that was resupplying the Japanese garrisons in New Georgia, and to patrol the Ferguson and [[Blackett Strait]]s to sight and to give warning when the Japanese [[Tokyo Express]] warships came into the straits to supply Japanese forces in the New Georgia–Rendova area.<ref name="Naval History" />

On {{nowrap|1 August}}, an attack by 18 Japanese bombers struck the base, wrecking ''PT-117'' and sinking ''PT-164''. Two torpedoes were blown off ''PT-164'' and ran erratically around the bay until they ran ashore on the beach without exploding.<ref>{{cite web |title=Pacific Wrecks-PT-117 |publisher=Pacific Wrecks, Inc. |url=https://www.pacificwrecks.com/ships/ptboat/PT-117.html |access-date=14 June 2018}}</ref>

===Crew on ''PT-109''{{'}}s last mission===
The following men were aboard on PT-109's last mission:

The last living survivor of ''PT-109'', he died in Florida in 2001.

===Battle of Blackett Strait===
{{Distinguish||text=the earlier battle at the same location, also known as the [[Battle of Blackett Strait]]}}[[File:Lt. John F. Kennedy skipper aboard the PT-109.jpg|left|thumb|Lt. JG Kennedy at the helm of ''PT-109'']]
At the end of July 1943, intelligence reports were received and decoded by Naval authorities at Kennedy's PT base on Rendova Island, indicating that five enemy destroyers were scheduled to run the night of 1–2 August.  The destroyers would cruise from the Solomon [[Bougainville Island]] through Blackett Strait to supply provisions and bring troops to the Japanese garrison on Vila Plantation, on [[Kolombangara]] Island's southern tip. America's sophisticated deciphering of the Japanese naval codes had contributed to the victory at the Battle of Midway, ten months earlier, and the same technology had been used to break their code and provide the report of the Japanese destroyers expected 1–2 August. Despite the recent loss of two boats and two crewmen from a Japanese air attack on {{nowrap|1 August}}, the skippers of ''PT-109'' and 14 other boats met with Commander Thomas G. Warfield to discuss the details of a mission to head north through a cut in the reefs known as Ferguson Passage, to Blackett Strait between [[Gizo, Solomon Islands|Gizo]] and Kolombongara Islands to block or attack the anticipated enemy destroyers. The resulting skirmish, sometimes referred to as the "Battle of Blackett Strait," should not be confused with an [[Battle of Blackett Strait|earlier battle of that name]] fought there on 6 March 1943. [[Commander (United States)|Commander]] [[Arleigh Burke]] had been ordered to sit on the northern approach to Kolombangara with seven American destroyers to ensure the Japanese were prevented from reinforcing their garrison, though he was not on station till 12:30&nbsp;a.m. All four Japanese destroyers would evade his grasp, as they arrived one hour early, before Burke had reached his post.{{sfn|Hamilton|1992|p=557}}{{sfn|Dallek|2003|p=95}} The resulting battle would become the largest use of PT boats in the war, and the results would not be promising for the future use of PTs against Japanese destroyers.<ref name="DANFS" />{{sfn|Doyle|2015|p=73}}

====Failure of the PTs' torpedoes in action====
On 1 August, fifteen PT boats, including ''PT-109'', motored from the PT base on Rendova around 6:30&nbsp;p.m. on strict but cursory orders from Rendova's Commander Thomas Warfield.  The combined PT task force was divided into four divisions of roughly four PTs each. ''PT-109''{{'}}s "B" division also included PTs ''162'', ''159'', and ''157'', and were stationed the farthest north of the PT divisions, nearly midway up Kolombongara Island's western coast and around {{convert|6|mi|km}} to the west.  The "B" Division left Rendova first, leading the pack, as their station was the farthest from the Rendova base.<ref>Logeval, Fredrick, ''JFK: Coming of Age in the American Century, 1917-1956'', (2020), Random House, New York, p. 339</ref> Most of the divisions reached their station by 8:30&nbsp;p.m.  The fifteen PTs carried four torpedo tubes each, for a total of {{nowrap|60 Mark 8 torpedoes}}, and roughly half of these were fired at the four advancing Japanese destroyers protected by Japanese float planes.{{sfn|Donovan|2001|pp=95, 99}}  The Navy's official report of the incident listed 5–6 torpedo explosions reaching the destroyer targets, but none, in fact, actually hit.  Of the twenty-four torpedoes fired by PT boats from eight of the PTs, not a single hit was scored against the advancing destroyers.  Though each division of PTs was assigned a location likely to intercept the destroyers, several of those without radar cruised about aimlessly in the fog and darkness, unable to locate the enemy ships.{{sfn|Donovan|2001|p=98}}

====Separation of ''PT-109'' from her division====
[[File:1942 JFK uniform portrait.jpg|upright|right|thumb|Lieutenant JG Kennedy, official naval photo, 1942]]
Lieutenant Brantingham on ''PT-159'', leader of Kennedy's division, and originally stationed near Kennedy, first saw radar blips indicating the southbound destroyers just arriving on the scene, and fired his torpedoes from about {{convert|1|mi}} away. As he advanced, he did not radio ''PT-109'' to follow, leaving Kennedy and his crew behind in the darkness.  All of Brantingham's torpedoes missed the destroyers, and his torpedo tubes caused a small fire, requiring Lieutenant Liebenow's PT, also in Kennedy's division, to swing in front of Brantingham's PT in an effort to block the light from his burning torpedo tubes, which could have given away their location to the destroyers.  Liebenow's ''157'' fired two more torpedoes that failed to hit their target as well, then both boats laid smoke from their smoke generators and zigzagged away to avoid detection.  No signal of the destroyer's presence was ever radioed or received by ''PT-109'', or the other boat in the division, and skippers Brantingham and Liebenow headed blindly west to Gizo Island and away from the destroyers and ''PT-109''.{{sfn|Hamilton|1992|p=558}}

Many of the torpedoes that were fired exploded prematurely or ran at the wrong depth. A few other PTs, including the leader of Division A to the south of Kennedy, intercepted the destroyers on their southbound route close to Kolombangara, but were unable to hit any with torpedoes.  The boats were radioed by Warfield to return when their torpedoes were expended, but the four boats with radar fired their torpedoes first and were ordered to return to base. Commander Warfield's concept of sending orders to the PTs in darkness by radio from {{convert|40|mi}} away, without a view of the battle, was inefficient at best.  The radar sets on the four boats carried were relatively primitive and sometimes malfunctioned.  When the four boats with radar left the scene of the battle, the remaining boats, including ''PT-109'', were deprived of the ability to determine the location or approach of the oncoming destroyers, and were not notified that other boats had already engaged the enemy.

Late in the night, ''PT-109'' and two accompanying PTs became the last to sight the Japanese destroyers returning on their northern route to [[Rabaul]], [[New Britain]], [[New Guinea]], after they had completed dropping their supplies and troops at 1:45&nbsp;a.m. on the southern tip of Kolombangara.<ref>1:45 am in Fleming, Thomas, "War of Revenge", Spring 2011, ''MHQ: The Quarterly Journal of Military History'', p. 19.</ref> The official Navy account of the incident listed radio communications as good, but PT commanders were also told to maintain radio silence until informed of enemy sightings, causing many commanders to turn off their radios or not closely monitor their radio traffic, including Kennedy.{{sfn|Donovan|2001|pp=96–99}}{{sfn|Doyle|2015|pp=32–172, 72–176}}<ref name="PT-109 Loss Report">{{cite web |title=Report on Loss of ''PT-109'' |date=24 November 2014 |orig-year=13 January 1944 |publisher=Naval History and Heritage Command |url=https://www.history.navy.mil/content/history/nhhc/research/histories/biographies-list/bios-k/kennedy-john-f/report-on-loss-of-pt-109.html |access-date=28 June 2018}}</ref>

====Rammed by ''Amagiri'', 2 August====
[[File:Amagiri 1930.jpg|upright=1|right|thumb|Japanese destroyer {{ship|Japanese destroyer|Amagiri|1930|2}} in 1930]]

By 2&nbsp;a.m. on {{nowrap|2 August}} 1943, as the battle neared its end, ''PT-109'', ''PT-162'', and ''PT-169'' were ordered to continue patrolling the area on orders previously radioed from Commander Warfield.{{sfn|Donovan|2001|pp=99, 100}}  The night was cloudy and moonless, and fog had set amidst the remaining PTs.  Kennedy's boat was idling on one engine to avoid her phosphorescent wake being seen by Japanese aircraft when the crew realized they were in the path of the Japanese destroyer {{ship|Japanese destroyer|Amagiri|1930|2}}, which was heading north to Rabaul from Vila Plantation, [[Kolombangara]], after offloading supplies and {{nowrap|902 soldiers}}.{{sfn|Donovan|2001|pp=60, 61, 73, 100}}

Most contemporary accounts of the incident, particularly the work of Mark Doyle, do not find Kennedy at fault for the collision.  The lack of speed and maneuverability of ''PT-109'' while the engines were idling put the vessel at risk from passing destroyers, but Kennedy had not been warned by radio of destroyers in the area. Kennedy believed the firing he had heard was from shore batteries on Kolombangara, not destroyers, and was focused on avoiding detection by enemy seaplanes.{{sfn|Donovan|2001|pp=96–99}}{{sfn|Doyle|2015|pp=72–176}}

Kennedy said he attempted to turn ''PT-109'' to fire a torpedo and have Ensign George "Barney" Ross fire their newly installed 37&nbsp;mm anti-tank gun from the bow at the oncoming northbound destroyer ''Amagiri'', but Ross did not have time to load a shell into the closed breech of the weapon.{{sfn|Donovan|2001|pp=101, 102, 106, 107}} ''Amagiri'' was traveling at a relatively high speed of between {{convert|23|and|40|kn}} to reach harbor by dawn, when Allied air patrols were likely to appear.{{sfn|Doyle|2015|pp=134–176}}<ref>Tried to fire the anti-tank gun in {{harvnb|Doyle|2015|p=94}}</ref>

Kennedy and his crew would have had less than ten seconds to get the engines up to speed to evade the oncoming destroyer, which was advancing without running lights.  ''PT-109'' was struck on her starboard side at a 20-degree angle shearing off a piece of the boat, between Kolombangara and [[Ghizo Island]], near {{coord|8|3|S|156|56|E|type:event|name=ramming of PT-109}}.<ref name=RefNatGeoMap>{{cite web |title=Map of PT-109 Wreck Site (Kennedy) |url=http://news.nationalgeographic.com/news/2002/07/photogalleries/0702_pt109.html |work=National Geographic News |date=2002 |access-date=3 May 2014 |archive-url=https://web.archive.org/web/20140428055400/http://news.nationalgeographic.com/news/2002/07/photogalleries/0702_pt109.html |archive-date=28 April 2014 |url-status=dead}}</ref>{{sfn|Logevall|2020|p=340}} There are conflicting accounts as to whether the destroyer captain had rammed PT-109 intentionally. ''Amagiri''{{'}}s captain, Lieutenant Commander Kohei Hanami, later claimed that he intentionally turned hard to starboard and deliberately [[Ramming#Naval warfare|rammed]] ''PT-109''. However, Hanami's superior officer, Commander of the 11th Destroyer Flotilla, Captain Katsumori Yamashiro, and other crewmembers, recalled Yamashiro ordering Hanami to turn hard to port to try to avoid hitting the torpedo boat, for fear of setting off its torpedoes and damaging their ship. He was however, unable to avoid hitting it despite the evasive maneuver.<ref>{{cite journal |last1=Yellen |first1=Jeremy |last2=Tomsovic |first2=Phil |date=Fall 2024 |title=Lost in Translation?: PT-109 and Storytelling in U.S.-Japan Relations |url=https://online.ucpress.edu/phr/article/93/4/626/203408/Lost-in-Translation-PT-109-and-Storytelling-in-U-S |journal=Pacific Historical Review |volume=93 |issue=4 |pages=626–657 |doi=10.1525/phr.2024.93.4.626 |access-date=17 October 2024|url-access=subscription }}</ref>{{sfn|Doyle|2015|pp=96–97, 72–176}}

====''PT-109'' explodes====
When ''PT-109'' was cut in two around 2:27&nbsp;a.m.,<ref>2:27 a.m. in {{harvnb|Doyle|2015|p=95}}</ref> a fireball of exploding aviation fuel {{convert|100|ft|m|}} high caused the sea surrounding the ship to flame. Seamen Andrew Jackson Kirksey and Harold William Marney were killed instantly, and two other members of the crew were badly injured and burned when they were thrown into the flaming sea surrounding the boat. For such a catastrophic collision, explosion, and fire, there were few men lost compared to the losses on other PT boats hit by shell fire. ''PT-109'' was gravely damaged, with watertight compartments keeping only the forward hull afloat in a sea of flames.{{sfn|Doyle|2015|pp=72–176}}<ref>100-foot high fireball in {{harvnb|Doyle|2015|pp=96–97}}</ref>

''PT-169'', closest to Kennedy's craft, launched two torpedoes, but they missed the attacking destroyer; ''PT-162''{{'}}s torpedoes failed to launch. Both boats then turned away from the scene of the action and returned to base without checking for survivors of ''PT-109''. No procedure had been specified by Commander Warfield for searching for survivors or what the PT flotilla should do when a boat was lost.{{sfn|Doyle|2015|pp=72–176}}  In the words of Captain Robert Bulkley, naval historian, "This was perhaps the most confused and least effectively executed action the PTs had been in. Eight PTs fired 30 torpedoes. The only confirmed results were the loss of ''PT-109'' and damage to the Japanese destroyer ''Amagiri''" [from striking ''PT-109''].<ref>{{cite book |last=Bulkley |first=Robert J.

Kennedy, a skilled swimmer who had been a member of the [[Harvard University]] swim team, used a life jacket strap clenched between his teeth to tow McMahon.{{sfn|Donovan|2001|pp=7, 123–124}} It took five hours to swim the {{convert|3.5|mi|km}} to the island, which they reached without encountering sharks or crocodiles.<ref>Ballard, Robert.

====Additional swims, 2, 4, and 5 August====
Plum Pudding Island was only {{convert|100|yd|m}} in diameter, with no food or water. The exhausted crew dragged themselves behind the tree line to hide from passing Japanese barges. The night of 2 August, Kennedy swam {{convert|2|mi|km}} to Ferguson Passage to attempt to hail a passing American PT boat.  On 4 August, he and Lenny Thom assisted his injured and hungry crew on a demanding swim {{convert|3.75|mi|km}} south to Olasana Island, which was visible from Plum Pudding Island. They swam against a strong current, and once again, Kennedy towed McMahon by his life vest.  They were pleased to discover Olasana had ripe coconuts, though there was still no fresh water.<ref name="BBC">{{cite news |url=https://news.bbc.co.uk/1/hi/world/asia-pacific/3107103.stm |title=JFK's epic Solomons swim |work=BBC News |date=30 July 2003 }}</ref> On the following day, 5 August, Kennedy and George Ross swam for an hour to Naru Island, visible at an additional distance of about {{Convert|0.5|mi|km}} southeast, in search of help and food and because it was closer to Ferguson Passage where Kennedy might see or swim to a passing PT boat on patrol.  Kennedy and Ross found a small canoe, packages of crackers and candy, and a fifty-gallon drum of drinkable water left by the Japanese, which Kennedy paddled back to Olasana in the acquired canoe to provide his crew.  It was then that Kennedy first spoke to native [[Melanesians|Melanesian]] [[coastwatchers]] [[Biuku Gasa and Eroni Kumana]] on Olasana Island.  Months earlier, Kennedy had learned a smattering of the pidgin English used by the coastwatchers by speaking with a native boy.  The two coastwatchers had finally been convinced by Ensign Thom that the crew were from the lost ''PT-109'', when Thom asked Gasa if he knew John Kari, and Gasa replied that he worked with him.{{sfn|Doyle|2015|pp=143–148}}  Realizing they were with Americans, the coastwatchers brought a few yams, vegetables, and cigarettes from their dugout canoe and vowed to help the starving crew.,{{sfn|Doyle|2015|pp=72–176}}<ref>Thom convinced the natives they were Americans in {{harv|Doyle|2015|p=146}}</ref> though it would take two additional days for a full rescue.<ref>Hamilton, Nigel, ''JFK, Reckless Youth'', (1992) Random House, New York, NY, p. 141, {{ISBN|0-679-41216-6}}</ref>

==Rescue==
The rescue of ''PT-109'' was a long process, largely achieved by the work of native Solomon Island scouts who first located Kennedy and his crew. The scouts were sent by Sub-lieutenant [[Arthur Reginald Evans|Reg Evans]], an Australian [[coastwatcher]], who had seen the ''109'' explode from his secret observation site.

===Aerial search of ''PT-109'' sinking site===
The explosion and resulting fireball on the early morning of {{nowrap|2 August}} was spotted by Evans, who manned a secret observation post at the top of the [[Mount Veve]] volcano on Kolombangara; more than 10,000 Japanese troops were garrisoned below on the southeast portion. The Navy and its squadron of PT boats held a memorial service for the crew of ''PT-109'' after reports were made of the large explosion, but Commander Warfield, to his credit, ordered an aerial search by [[Royal New Zealand Air Force]] [[P-40]] fighters that spotted a few remains of the wreck, but not the crew, who had already swum to safety.{{sfn|Doyle|2015|pp=134–176}}

====Coastwatchers Gasa and Kumana, 5 August====
Evans had been the first to dispatch islander scouts, Gasa and Kumana, in a [[dugout canoe]] late on 5 August, to look for possible survivors after decoding radio broadcasts that the explosion he had witnessed was ''PT-109''. Gasa and Kumana had been trained by the British and Australians in search and detection and were willing to sacrifice their lives as part of their duty to the British and American troops.  Native coastwatchers were used because they could avoid detection by Japanese ships and aircraft and, if spotted, would probably be taken for native fishermen.

Before they were rescued by the scouts on 8 August, Kennedy and his men survived for six days on Plum Pudding and then on Olasana Island. They had eaten only a few ripe coconuts, rainwater caught on leaves, and small amounts of fresh water and Japanese cookies Kennedy had taken from Naru Island. By chance, Gasa and Kumana stopped by Naru to investigate a Japanese wreck, from which they salvaged fuel and food. They first fled by canoe from Kennedy, who, with his sunburn, beard, and disheveled clothing, appeared to them to be a Japanese soldier. When they later arrived on Olasana, they pointed their [[Thompson submachine gun|Tommy guns]] at the rest of the crew, since the only light-skinned people they expected to find were Japanese, with whom they could not communicate.{{sfn|Doyle|2015|pp=72–176}}

====Thom's and Kennedy's rescue messages====
Kennedy's message scratched on a coconut while he was on Naru, where he had spent some time from 4 August to 7 August, was not the only communication given to the coastwatchers. A more detailed message was written by the executive officer of ''PT-109'', Ensign Leonard Jay Thom, on 6 August. Thom's message was a "penciled note" written on paper, which read:<ref name="PT-109 Loss Report"/><ref name="Beacon">{{cite web |last1=Sondles  |first1=Jeff |author2=Liberty Aviation Museum |date=31 July 2013 |title=Lenny Thom and PT 109 |work=The Beacon |publisher=Schaffner Publications, Inc |url=http://www.thebeacon.net/local-news/around-ottawa-county/item/3245-lenny-thom-and-pt-109/3245-lenny-thom-and-pt-109 |access-date=21 March 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140318193246/http://www.thebeacon.net/local-news/around-ottawa-county/item/3245-lenny-thom-and-pt-109/3245-lenny-thom-and-pt-109 |archive-date=18 March 2014}}</ref>

[[File:JFK PT-109 Coconut.jpg|right|thumb|The coconut with the carved message, cast in a paperweight]]
Though the 1963 movie depicted Kennedy offering a coconut inscribed with a message as his idea and the sole form of communication, it was Gasa who suggested it, and Kumana who climbed a coconut tree to pick one. On the instructions of Gasa, Kennedy painstakingly scratched the following message on the coconut husk with a knife:{{sfn|Doyle|2015|pp=72–176}}

====Coastwatchers' canoe trip from Olsana to the PT base, 6 August====
On 6 August, Gasa and Kumana left Olasana and headed east, carrying the penciled note and Kennedy's coconut message {{convert|10|nmi|mi km|spell=in}} to Wana Wana Island, south of Kolombangara and a quarter of the way to Kennedy's PT Naval base on Rendova Island.{{sfn|Hamilton|1992|p=591}} There, they took little time to rest but linked up with Senior Scout Benjamin Kevu, whom they told they had found the crew of ''PT-109''. Kevu sent another scout to inform Evans, north on Kolombangara Island, of the discovery. Gasa and Kumana departed Wana Wana with scout John Kari in a better canoe given them by Kevu, carrying both Thom's and Kennedy's messages to a military outpost on Roviana Island, close to the PT Rendova base in a total of fifteen hours by paddling their canoe all night through {{convert|38|mi|abbr=on}} of rough seas and hostile waters patrolled by the Japanese. Traveling in an arranged boat, Gasa and Kumana were at last sent south to the PT base at Rendova from Roviana Island, a distance of only {{convert|3|mi|km}}, with Gasa still clutching the coconut. Around 6 August, after speaking to Kevu about the eleven found on Olasana, Evans sent a canoe with fresh fish, yams, potatoes, corned beef hash, and rice to Kennedy and his crew with a message to return to him on Kolumbangara's Gomu Island in the canoe immediately. Kennedy followed this request and was the only one of his crew to go, since many Japanese planes were flying above and the coast watchers' station was on the Japanese-occupied island of Wana Wana. Kennedy was instructed to lie underneath palm fronds in the canoe so he would not be spotted by Japanese planes.<ref>{{cite book |last=Tregaskis |first=Richard |year=2016 |title=John F Kennedy and PT-109 |publisher=Open Road Media |location=New York, NY |pages=Chapter 10}}</ref> It was not until the morning of 7 August that Evans was able to radio Rendova to confirm the news that Kennedy and his crew had been discovered.{{sfn|Doyle|2015|pp=153, 173, 156, 134–176}}

====Battle of Vella Gulf, Admiral Halsey, 6–7 August====
{{Main|Battle of Vella Gulf}}
On the night of 6–7 August, while Kennedy still awaited rescue, Admiral [[William Halsey]], now convinced that PTs were unsuitable against Japanese destroyers, sent six U.S. Navy destroyers equipped with more advanced radar to intercept the "Tokyo Express", again on their frequent run to Kolombangara Island. This time, the U.S. forces succeeded and sank four Japanese destroyers, two of which, the ''Arashi'' and ''Hagikaze'', had eluded Kennedy and the 14 PT crews on the night of 1–2 August. This action became known as the [[Battle of Vella Gulf]].{{sfn|Doyle|2015|p=155}}

====''PT-157'' makes final rescue, 8 August====
On 7 August, when the coastwatcher scouts carrying the coconut and paper message arrived at Rendova, PT Commander Warfield was at first skeptical of the messages and the trustworthiness of the native scouts Gasa and Kumana. After finally receiving Evans' radioed message of the discovery of the ''109'' crew, and facing overwhelming evidence that Kennedy had returned from the dead, he cautiously consented to risk two PTs to rescue them. Warfield selected ''PT-157'', commanded by Kennedy's friend and former tentmate Lieutenant William Liebenow, for the rescue, as he and his crew were experienced and familiar with the area. Liebenow later said that his crew was chosen because they were "the best boat crew in the South Pacific."<ref>Contrera, Jessica, "He saved JFK's life with the help of a coconut," ''Chicago Tribune'' Section 1, 31 August 2018.  Obituary for William Liebenow, with quotation of WL by Contrera.</ref> ''PT-171'' would travel ahead and radio Liebenow of any sightings of the enemy. Departing just after sunset from Rendova at 7:00&nbsp;p.m. on 8 August, Liebenow motored ''PT-157'' to Evans' base at Gomu Island, off Kolombangara. To avoid making a wake, Liebenow traveled at {{convert|10-15|kn}}, muffled his engines, and zigzagged to prevent being tracked by planes or shore batteries. The arranged signal when Liebenow picked up Kennedy on Gomu was four shots, but since Kennedy only had three bullets in his pistol, Evans gave him a Japanese rifle for the fourth signal shot. With Kennedy aboard, ''PT-157'' rescued the weak and hungry ''PT-109'' crew members on Olasana Island in the early morning of 8 August, after dispatching rowboats to pick them up. The ''157'' then motored the full crew and the coastwatcher scouts {{convert|40|mi|km|spell=in}} back to the Rendova PT base, where they could begin to receive medical attention.{{sfn|Doyle|2015|pp=134–176, 164–5}}

===Aftermath===
[[File:JF Kennedy awarded medal.jpeg|upright|thumb|Kennedy receiving the [[Navy and Marine Corps Medal]]]]There were reporters aboard ''PT-157'' when they rescued Kennedy and his crew from Olasana Island.

A 2003 article in ''[[Naval History]]'' raised the possibility that Kennedy and McMahon conspired to mask the cause of ''109''’s failure to evade ''Amigiri''. It examined Kennedy's supposed statement to another PT officer that ''109'' had stalled because its muffler flaps had not first been opened when its engines had been throttled up.  If, as radioman Maguire reported decades later, Kennedy signaled McMahon to speed up, it would have been McMahon's duty—and Kennedy's responsibility—first to open the flaps, which, in the other officer's account, were closed for quiet running. "[A]t no time did [Kennedy] ever officially or publicly acknowledge having sent a signal to the engine room to increase speed. ... [McMahon] consistently played ignorant of any signal from Kennedy."<ref>{{cite web |last=Nelson |first=Curtis L. |url=https://www.usni.org/magazines/naval-history-magazine/2003/february/did-jfks-order-sink-pt-109 |title=Did JFK's Order Sink PT-109? |work=Naval History |date=February 2003 |access-date=22 October 2024 }}</ref>

Both Solomon Islanders, Biuku Gasa and Eroni Kumana, were alive when visited by ''National Geographic'' in 2002.<ref>{{cite web |last=Chamberlain |first=Ted |date= 20 November 2002 |title=JFK's Island Rescuers Honored at Emotional Reunion |publisher=National Geographic News |url=http://news.nationalgeographic.com/news/2002/11/1120_021120_kennedy_pt_109.html |archive-url=https://web.archive.org/web/20021124130915/http://news.nationalgeographic.com/news/2002/11/1120_021120_kennedy_pt_109.html |url-status=dead |archive-date=24 November 2002 |access-date=2 January 2012}}</ref> They were each presented with a bust and a letter from the Kennedy family.

Kennedy invited both Gasa and Kumana to his inauguration, but the island authorities gave their trip to local officials instead. Kumana and Gasa made it to the airport in Honiara, but were turned back by Solomon Island officials because their appearance and pidgin English would be an embarrassment.<ref name="John F. Kennedy Library">{{cite book |author=John F. Kennedy Library |date=3 August 2009 |title=John F. Kennedy Press Release}}</ref> Gasa and Kumana gained recognition, especially after being mentioned and praised by ''National Geographic'', and the publication of William Doyle's book on ''PT-109''.  Gasa died in late August 2005, his death noted only in a single blog post by a relative.<ref>{{harvnb|Doyle|2015|pp=72–176}}</ref>

In 2007, the commanding officer of [[USS Peleliu (LHA-5)|USS ''Peleliu'']], Captain Ed Rhoades, presented Kumana with gifts, including an American flag, for his actions more than 60 years earlier.<ref>{{cite web |last=Francis |first=Mike  |date=18 September 2007 |title=Eroni Kumana gets his flag |work=[[The Oregonian]] |url=http://blog.oregonlive.com/oregonatwar/2007/09/eroni_kumana_gets_his_flag.html |access-date=2 January 2012}}</ref>

In 2008, Mark Roche visited Kumana and discussed the ''PT-109'' incident. Kumana had been a scout for the Coastwatchers throughout the war, and besides rescuing the crew of ''PT-109'', he had rescued two downed American pilots who parachuted into the sea. Kumana noted that Kennedy visited him several times while still stationed at Rendova and always brought trinkets to swap. Kumana lived atop a cliff on his native island with his extended family. His most prized possession was a bust of President Kennedy, later given to him by the Kennedy family. Kumana gave Roche a valuable family heirloom, a large piece of [[Shell money|Kustom Money]], to place on the President's grave. (Among other uses, Kustom Money was used to pay tribute to a chief, especially by placing it on the chief's grave.) In November 2008, Roche placed the tribute on the President's grave in a private ceremony. The artifact was then taken to the Kennedy Library and placed on display beside the coconut with the rescue message.<ref name="John F. Kennedy Library"/>

Kumana died on {{nowrap|2 August}} 2014, exactly 71 years after ''PT-109''{{'}}s collision with ''Amagiri''. He was 93.<ref>{{cite news |date=4 August 2014 |title=Solomon Islanders mourn death of Eroni Kumana who helped save life of John F.

==Search for the remains of ''PT-109''==
The wreckage of ''PT-109'' was located in May 2002, at a depth of {{convert|1200|ft}}, when a National Geographic Society expedition headed by [[Robert Ballard]] found a torpedo tube from wreckage matching the description and location of Kennedy's vessel.<ref name=NatGeoPT109>{{cite web |last=Chamberlain |first=Ted |title=JFK's PT-109 Found, U.S. Navy Confirms |work=National Geographic News |date=11 July 2002 |publisher=National Geographic Society |url=http://news.nationalgeographic.com/news/2002/07/0709_020710_kennedyPT109.html |archive-url=https://web.archive.org/web/20020802063053/http://news.nationalgeographic.com/news/2002/07/0709_020710_kennedyPT109.html |url-status=dead |archive-date=2 August 2002 |access-date=9 May 2014}}</ref> The boat was identified by Dale Ridder, a weapons and explosives expert on the U.S. Marine Forensics Panel.<ref name=NatGeoPT109/>

The stern section was not found, but a search using remote vehicles found the forward section, which had drifted south of the collision site. Much of the half-buried wreckage and grave site was left undisturbed in accordance with Navy policy. [[Max Kennedy]], JFK's nephew, who joined Ballard on the expedition, presented a bust of JFK to the islanders who had found Kennedy and his crew.<ref>{{Cite news|url=https://www.nytimes.com/2014/08/17/world/asia/eroni-kumana-who-saved-kennedy-and-his-shipwrecked-crew-dies-at-96.html|title=Eroni Kumana, Who Saved Kennedy and His Shipwrecked Crew, Dies at 96 |first=Paul |last=Vitello|date=16 August 2014|newspaper=[[The New York Times]]}}</ref>

''National Geographic'' produced a TV special titled ''[[The Search for Kennedy's PT 109]]''. A DVD and a book were also released.

===''PT-109'' and American–Japanese relations===
Nine years after the sinking of ''PT-109'', U.S. Representative John Kennedy, engaged in a race for the Senate, instructed his staff to locate Kohei Hanami, Commander of the ''Amagiri'', the Japanese destroyer that had run down the ''109''.  When they found Captain Hanami, Kennedy wrote him a heartfelt letter on 15 September 1952, with wishes of good fortune for him and for long-term peace between Japan and the United States.  The two became friends, and Hanami subsequently went into politics in 1954, being elected as councilman of Shiokawa, and later as mayor in 1962.  Hanami hoped to meet Kennedy on his next visit to Japan, and though the meeting never took place, the United States and Japan remained close allies.  Years later, [[Caroline Kennedy]] accepted the post of Ambassador to Japan, holding the office from November 2013 to 18 January 2017, extending the positive relationship with Japan her father had begun after the war.<ref>Relationship with Hanami in {{harvnb|Doyle|2015|pp= 212–16, 218–22, 241–42, 315–17}}</ref>

While Kennedy was running for president in [[1960 United States presidential election|1960]] he met with Fujio Onozeki, a Japanese naval officer who was aboard the ''Amagiri'' when it hit ''PT-109'', who gave him a card signed by other officers from the ''Amagiri''.<ref>{{cite news |date=1 November 1960 |title=Fujio Onozeki |work=Opelika Daily News |via=[[Newspapers.com]] |page=1 |url=https://www.newspapers.com/clip/46067086/opelika-daily-news/ |access-date=3 March 2020 |url-status=live |archive-url=https://archive.today/20200303224529/https://www.newspapers.com/clip/46067086/opelika-daily-news/ |archive-date=3 March 2020}}</ref>

===''PT-109'' in popular culture===
President Kennedy presented ''PT-109'' tie clasps to key supporters in his 1960 campaign,<ref name=PT109clip>{{Cite sign |title=Tie clip of PT-109 boat with "Kennedy" in black letters across bow |year=1960  |type=Campaign artifact |publisher=John F.

Kennedy's run for President in 1960 to promote his military experience in WWII}}</ref> as well as to close friends and staff members.  Replicas of the tie clasps are still sold to the public by the [[John F. Kennedy Presidential Library and Museum]] in [[Boston, Massachusetts]].  An original flag from ''PT-109'' is now kept in the John F. Kennedy Library and Museum.  The story of ''PT-109''{{'}}s sinking was featured in several books and a 1963 movie, [[PT 109 (film)|''PT 109'']], starring [[Cliff Robertson]]. Kennedy's father, Joe Kennedy Sr., had a role in the production, financing, casting, and writing.<ref>{{cite journal |last=Hinds |first=Joseph |date=February 2011 |title=JFK's Other PT Boat Rescue |journal=America in WWII |pages=53–57}}</ref> As there were only a few 80-foot Elco ''PT-103''-class hulls in existence by that time (none in operable condition or resembling their World War&nbsp;II appearance), United States Air Force [[crash rescue boat]]s were modified to resemble ''PT-109'' and other Elco PTs in the movie.  Instead of the dark green paint used by PT boats in the Western Pacific theater during World War&nbsp;II, the film versions were painted the same gray color as contemporary U.S. naval vessels of the 1960s.

A song titled [[PT-109 (song)|"PT-109"]] by [[Jimmy Dean]] reached {{nowrap|No. 8}} on the pop music, and {{nowrap|No. 3}} on the [[country music]] charts in 1962, making it one of Dean's most successful recordings.<ref name=PIR_1>{{cite news |last=Szetu |first=Robertson |date=10 March 2005 |title=Kennedy Island sale to be challenged in Solomons |work=Pacific Islands Report |url=http://pidp.org/archive/2005/March/03-10-03.htm |access-date=6 August 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140808060636/http://pidp.org/archive/2005/March/03-10-03.htm |archive-date=8 August 2014}}</ref>

Eroni Kumana named his son "John F. Kennedy".<ref name=CoastalLiving.Rescued/> Plum Pudding Island was later renamed [[Kennedy Island]]. A controversy arose when the government sold the land to a private investor who charged admission to tourists.<ref name=PIR_1/>  ''PT-109'' was also the subject of toy, plastic, and radio control model ships in the 1960s, familiar to boys who grew up as [[baby boomers]]. It was still a popular {{nowrap|{{frac|1|72}} scale}} [[Revell]] ''PT-109'' (model) kit in the {{nowrap|21st century}}. Hasbro also released a ''PT-109'' edition of John F. Kennedy [[G.I. Joe]] action figure, dressed in Navy khakis with a miniature version of the famous coconut shell.{{citation needed|date=July 2023}}

Two episodes of the World War II–themed television series ''[[McHale's Navy]]'', which began airing during the Kennedy presidency, mention the ''PT-109'' and its unnamed captain from Massachusetts (whose speech and accent Ensign Parker imitates in one episode). In one episode, the boat's captain is the ultimate choice to be the face of a congresswoman's bond selling tour, and in the other, Captain Binghamton lists the ''PT-109''{{'}}s captain as someone who has recently been promoted and of whom he is envious.

A video game marketing itself as a torpedo boat simulation was released by [[Spectrum Holobyte]] in 1987 with the title ''[[PT-109 (video game)|PT-109]]''.
