The '''Heinkel He 115''' was an all-metal twin-engined military [[seaplane]] designed and produced by the [[Germany|German]] aircraft manufacturer [[Heinkel]]. Early on its flying history, the He 115 established several new international records for floatplanes.<ref name="Genus 1 p96"/>

The He 115 was developed during the latter half of the 1930s in response to a requirement issued by the German [[Ministry of Aviation (Nazi Germany)|''Reichsluftfahrtministerium'']] (RLM). Heinkel opted to design a three-seat seaplane that could function as a [[torpedo bomber]], [[reconnaissance]] aircraft and [[Naval mine|minelayer]]. The initial model of the aircraft, the first prototype of which performed its [[maiden flight]] in August 1937, was powered by a pair of 960&nbsp;PS (947&nbsp;hp, 720&nbsp;kW) [[BMW 132]]K nine-cylinder air-cooled [[radial engine]]s. Subsequent models varied in several respects, such as being equipped with different engines or alternative armament arrangements, increased fuel capacity or payload, and some He 115s could even accommodate an additional crew member.

The He 115 saw active combat with multiple operators, particularly during its service with the ''[[Luftwaffe]]'' during the [[Second World War]]. Early on in the conflict, German He 115s frequently deployed mines within British waters. It proved itself to be a capable anti-shipping platform, particularly against [[Arctic convoys of World War II|Arctic supply convoys]]. Other nations flew the He 115, the majority being [[Scandinavia]]n. The [[Royal Norwegian Navy Air Service]] operated a number that flew missions against [[Operation Weserübung|the German invasion of Norway]]; several survivors escaped the occupation by flying to the UK, where they continued to be flown against the Germans until they were lost. By the twenty-first century, while a few airframes have survived, none are currently on display to the public and none are flightworthy.

==Development and design==
The origins of the He 115 can be traced back to 1935 and the issuing of a requirement by the German [[Ministry of Aviation (Nazi Germany)|''Reichsluftfahrtministerium'']] (RLM) that called for a twin engined general purpose [[floatplane]], suitable for maritime patrol and anti-shipping strikes with both bombs and [[torpedo]]es. Numerous aircraft manufacturers responded with their own proposals, including Heinkel Flugzeugwerke and the [[Blohm & Voss]] aircraft subsidiary [[Hamburger Flugzeugbau]]. On 1 November 1935, orders were placed with both Heinkel and Hamburger Flugzeugbau to produce three [[prototype]]s of their prospective designs, designated the ''He 115'' and the [[Blohm & Voss Ha 140|Ha 140]] respectively.<ref name="Genus 1 p97">''Air International'' February 1987, p. 97.</ref><ref name="Donald German p108">Donald 1994, p. 108.</ref>

In terms of its general configuration, the He 115 was an all-metal mid-wing [[monoplane]] with a [[monocoque]] fuselage.<ref name = "smithkay 269"/> It was equipped with a pair of [[Float (nautical)|floats]], each of which was attached to the underside of the engine [[nacelle]]s via a large [[strut]]. The twin-[[Spar (aeronautics)|spar]] wing was built in three sections.<ref name = "smithkay 269"/> It featured a stepped cockpit along with a rear-facing observation compartment.<ref name = "smithkay 26970">Smith and Kay 1972, pp. 269-270.</ref> Initially, the He 115's armament consisted of two 7.92&nbsp;mm (.312&nbsp;in) [[MG 15 machine gun]]s, one in the nose and one in the dorsal position.<ref name="Genus 1 p97"/> On later-build He 115s, the typical armament fitted included a fixed forward-firing 15&nbsp;mm or 20&nbsp;mm [[MG 151 cannon]] and two rearward-firing 7.92&nbsp;mm (.312&nbsp;in) [[MG 17 machine gun]]s in the engine nacelles.<ref name="Genus 1 p101">''Air International'' February 1987, p. 101.</ref><ref name="Genus 2 p155">''Air International'' March 1987, p. 155.</ref> Furthermore, some variants carried [[LTF 5 torpedo|LTF 5]] or [[LTF 6b torpedo]]es and [[SD 500 bomb|SD 500]] {{convert|500|kg|lb|abbr=on}} or [[SC 250 bomb|SC 250]] {{convert|250|kg|lb|abbr=on}} bombs, while others carried [[LMB III mine|LMB III]] or [[LMA mine]]s.

During August 1937, the first prototype He 115 performed its [[maiden flight]].<ref name = "smithkay 270">Smith and Kay 1972, p. 270.</ref> Flight testing went relatively smoothly, the type's flight characteristics proving to be quite favourable.<ref name = "smithkay 269"/> In early 1938, the He 115 was selected over the rival Ha 140, thus securing a second order for another prototype and 10 pre-production aircraft.<ref name="Genus 1 p97"/> According to aviation historian Hans Amtmann, Hamburger Flugzeugbau did not have enough spare manufacturing capacity for series production and declined the order, leading to Heinkel's selection instead.<ref>Hans Amtmann; "Blohm & Voss Remembered", ''Aeroplane Monthly'', February 1988, pp. 25-26.</ref> During March of that year, the first prototype was used to establish a series of international records for floatplanes over {{convert|1000|km|mi|abbr=on}} and {{convert|2000|km|mi|abbr=on}} closed circuits at a speed of {{convert|328|km/h|mph|abbr=on}}.<ref name="Genus 1 p96">''Air International'' February 1987, p. 96.</ref> Prior to these records being set, the prototype had been modified to achieve greater aerodynamic performance, such as the deletion of the angular glazed nose and the rear compartment, which were replaced by [[Aircraft fairing|fairing]]s.<ref name = "smithkay 270"/>

The third and fourth prototypes including a continuous glazed canopy (between the windshield and the rear position) and angled [[Bracing (aeronautics)|bracing]] struts between the vertical struts attached to the floats respectively.<ref name = "smithkay 270"/> In 1937, ten pre-production He 115s were completed; deliveries of production standard aircraft to the ''[[Luftwaffe]]'' commenced one year later. The He 115A-3 was the first variant to be produced in quantity, it differed from earlier models by having a revised [[bomb bay]] and radio apparatus. During 1939, the improved HE 115B-1, which featured a more than 50 percent increase in fuel capacity, was introduced.<ref name = "smithkay 270"/>

While production came to an end during the first half of the [[Second World War]], the He 115 was highly regarded, to the extent that production was resumed in 1943, despite an increasingly large proportion of German's aircraft manufacturing capacity being allocated to defensive [[fighter aircraft]] instead.<ref name = "smithkay 269734">Smith and Kay 1972, pp. 269, 273-274.</ref>

==Operational history==

===''Luftwaffe''===

[[File:Heinkel He 115 plane on crane c1940.jpg|thumb|A German Heinkel He 115B of 1./Küstenfliegergruppe 206 on a crane.]]
Throughout the Second World War, the primary mission of the Luftwaffe's He 115s was to conduct minelaying, typically during night time to lower the likelihood of interception.<ref name = "smithkay 269">Smith and Kay 1972, p. 269.</ref> Following the first such mission on 20 November 1939, the He 115 was frequently used for dropping (typically via [[parachute]]) [[magnetic mine]]s in British waters, normally aiming for narrow passages close to busy ports on the English south coast; the [[River Thames]] was also a prime target. These mining efforts supplemented the efforts of the ''[[Kriegsmarine]]''.<ref name = "smithkay 2712">Smith and Kay 1972, pp. 271-272.</ref> The island of [[Sylt]] was used as a base for He 115s performing these missions; in response, it became a target for [[Strategic_bombing_during_World_War_II#Allied_bombing_of_Germany|Allied bombing]] missions.<ref name = "smithkay 272">Smith and Kay 1972, p. 272.</ref>

Perhaps the most effective missions performed by the He 115 were its anti-shipping operations against [[Arctic convoys of World War II|Arctic convoys]], for which it operated out of bases in [[German occupation of Norway|occupied northern Norway]]. Due to early convoys lacking any air cover, the slow and lightly armed He 115 was less vulnerable during these attacks than it was when operating near to the English coast. Following the appearance of [[aircraft carrier|carriers]] and [[escort aircraft carrier|escort carriers]], coupled with the arrival of new Soviet [[heavy fighter]]s like the [[Petlyakov Pe-3]]bis, ''Luftwaffe'' [[air superiority]] over the convoys was challenged and losses increased.{{citation needed|date=September 2024}}

Apart from its use as a [[minelayer]] and torpedo bomber, the He 115 was used for coastal reconnaissance and by [[KG 200]] to drop agents behind enemy lines.<ref>{{cite web|url=http://www.stahlbrandt.com/html/history/kg200.html|title=KG 200 -- Unternehmen Moewe -- history -- stahlbrandt.com|website=www.stahlbrandt.com}}</ref>

===Royal Norwegian Navy Air Service===

[[File:Heinkel He 115A-2 (He 115N) F.60 of the Royal Norwegian Navy Air Service.jpg|thumb|Norwegian He 115Ns in 1939–1940.]]
In response to the rising tensions in Europe, the [[Norwegian Ministry of Defence]] had ordered six He 115Ns for the [[Royal Norwegian Navy Air Service]] (RNoNAS) on 28 August 1939 and the aircraft were delivered from 14 July – 13 November 1939.<ref name="Norw. 115">Luftwaffe.no: [http://www.luftwaffe.no/SIG/Artikler/115.html Heinkel He 115 in Norway] {{webarchive|url=https://web.archive.org/web/20070928043156/http://www.luftwaffe.no/SIG/Artikler/115.html |date=28 September 2007 }}</ref> The He 115N order was intended to replace the RNoNAS fleet of 1920s vintage [[Douglas DT]] torpedo bombers and the obsolescent [[Marinens Flyvebaatfabrikk M.F.11]], which was the mainstay of the RNoNAS in 1940.<ref>Hafsten 2003, pp. 87–90.</ref> The Norwegians signed another order of six He 115Ns in December 1939, with delivery expected in March/April 1940 but this was forestalled by [[Operation Weserübung]], the German invasion of Norway of 9 April 1940.<ref name="Norw. 115"/> At the outbreak of hostilities, the RNoNAS had six He 115Ns in service (F.50, F.52, F.54, F.56, F.58 and F.60) spread along the coast from the naval air stations at [[Sola Air Station|Sola]] and [[Flatøy]] in the south to the one at [[Skattøra]] Naval Air Station outside [[Tromsø]] in the north. At the beginning of the German invasion, the aircraft at the seaplane base at [[Hafrsfjord]] near [[Stavanger]] (F.60) was captured by the Germans, but two ''Luftwaffe'' He 115s (given the codes F.62 and F.64 in Norwegian service) were seized by an improvised [[militia]] unit of Norwegian [[Rifleman|riflemen]] at [[Ørnes]] in [[Glomfjord]], [[Nordland]] and by [[police]] officers at [[Brønnøysund]], Nordland. The two aircraft were seized after they ran out of fuel and had to make emergency landings on 10 April. Manned by Norwegian aircrews, they served against their former owners for the duration of the campaign.<ref name = "smithkay 272"/>

Seven Norwegian He 115s, five of them He 115Ns, were employed against German and German-controlled ships (see: [[HNoMS Uller (1876-1940)|HNoMS ''Uller'']]), as well as providing [[Close air support|ground support]] to the [[Norwegian Army]] offensive on the [[Battle of Narvik#Land battle|Narvik Front]]. On 14 April 1940, three Norwegian He 115s made a successful attack on German Ju 52s at [[Gullesfjordbotn]]. Four of the Norwegian aircraft (F.52, F.56, F.58 and F.64) made the journey to the [[United Kingdom]] shortly before the 10 June 1940 surrender,<ref name = "smithkay 272"/> a fifth (F.50) escaping to [[Finland]], landing on Lake Salmijärvi in [[Pechengsky District|Petsamo]].<ref>FAF in Color: [http://www.sci.fi/~ambush/faf/fafincolor.html Finnish Air Force Aircraft: Heinkel He 115]{{dead link|date=March 2017 |bot=InternetArchiveBot |fix-attempted=yes}}</ref> A sixth He 115 (F.54) also tried to make the journey to Britain but was lost over the [[North Sea]]. The last of the Norwegian He 115s, F.62 (one of the two captured German aircraft), was unserviceable at the time of the evacuation and was abandoned at Skattøra, later being repaired and flown by the Germans.

===Royal Air Force===

The four escaped aircraft were reformed into the Norwegian [[Helensburgh]] Group under [[Commander]] Bugge.<ref name = "smithkay 272"/> The exiled Norwegian [[Cabinet Nygaardsvold]] made plans shortly after arriving in Britain to use the four He 115s to perform [[Pamphlet|leaflet]] dropping missions over Norway. This leaflet mission was to deliver a declaration to the [[Occupation of Norway by Nazi Germany|Norwegian people]], stating the Norwegian authorities were re-established in the UK and rejected any Nazi German overtures for a German–Norwegian peace deal. All four Norwegian He 115s were ordered from Helensburgh to Scapa Flow on 3 July 1940 to carry out the mission, although one had to return to Helensburgh due to engine problems. The three He 115s assembled at [[Scapa Flow]] were ordered to fly to Norway and drop the declaration over the cities of [[Oslo]], [[Bergen]] and [[Trondheim]]. Shortly before the mission was to get under way, the British [[Air Ministry]] intervened and stopped the expedition, insisting that such an undertaking would be suicidal to attempt with the slow flying He 115s. Three days later, the aircraft returned to Helensburgh.<ref>Hafsten 1991, p. 297.</ref>

Three of the Norwegian He 115s (F.56, F.58 and F.64) were subsequently used in covert operations off Norway and in the [[Mediterranean]] Sea with Norwegian crews. In British service, the three received new [[United Kingdom military aircraft serials|serial numbers]], ''BV184'', ''BV185'' and ''BV187''.<ref name="Norw. 115"/> ''BV184'' was attacked and damaged by two Polish [[Supermarine Spitfire|Spitfire]] fighters over the [[Bay of Biscay]] in the spring of 1942, while co-operating with French fishing boats and later lost in a refuelling fire in the UK.<ref>Berg 1997, p. 93.</ref><ref name="Norw. 115"/> ''BV185'' was destroyed in an Italian air raid on [[Kalafrana]], [[Malta]] after flying just one clandestine operation to North Africa.<ref name="Norw. 115"/><ref name = "smithkay 272"/> ''BV187'' flew several missions on the North African coast from its base in Malta before being destroyed by a pair of German Bf 109s.<ref name="Norw. 115"/>

===Finnish Air Force===

[[File:He115-hoytiainen.jpg|thumb|Heinkel He 115A of LeLv 15 on lake Höytiäinen. August 1941.]]
On 8 June 1940, the day after Norwegian forces were ordered to cease hostilities, one He 115 (F.50, deemed technically unfit to be flown to the UK), was flown to Finland posing as a civilian aircraft LN-MAB. The floatplane was [[internment|interned]] but the pilot, experienced line captain and naval lieutenant Helge Dahl and crew were free to leave Finland. From Summer 1941, it was used by the [[No. 14 Squadron, Finnish Air Force|LLv.14]] of the [[Finnish Air Force]] code HE-115 and named "Jenny", to ferry [[Sissi (Finnish guerrilla)|''Sissi'']] troops behind Soviet lines. In this role, it proved valuable in a terrain with numerous secluded lakes. It served in this role until ambushed in [[East Karelia]] on 4 July 1943. ''Jenny'' took off but soon had to ditch and the crew was taken prisoner. Two days later the floating HE-115 was strafed by Finnish [[Morane-Saulnier MS.406]] fighters. There are reports that the Soviets salvaged the wreck for evaluation.<ref name="Norw. 115"/> A pair of Luftwaffe He 115 C were borrowed for similar operations in 1943–44 and operated with German markings by Finnish crew. One was returned in 1944 but the other was surrendered to the Soviets after the signing of the [[Moscow Armistice]].{{citation needed|date=September 2024}}

===Swedish Air Force===

The [[Swedish Air Force]] operated 12 He 115A-2s under the local designation '''T 2''', with Air Force numbers 101–112. Another six aircraft were ordered but never delivered due to the outbreak of the Second World War. They were sturdy and well liked by their crews and were not taken out of use until 1952. The Swedish T 2s were kept on duty throughout the Second World War and made a valuable contribution to protecting and enforcing [[Swedish neutrality]]. The T 2s replaced the outdated '''T 1s''' ([[Heinkel HD 16]]s) as torpedo bombers and also served as regular bombers, for smoke screening and for long-range reconnaissance missions. Five of the 12 T 2s were lost in accidents during their service with the Swedish Air Force.<ref>Avrosys.nu: [http://www.avrosys.nu/aircraft/Torped/192T2.htm T 2 - Heinkel He 115 (1939-1952)] {{webarchive|url=https://web.archive.org/web/20070205042729/http://www.avrosys.nu/aircraft/Torped/192T2.htm |date=5 February 2007 }}</ref>
