USS O-9 (SS-70), also known as "Submarine No. 70", was one of 16 O-class submarines of the United States Navy commissioned during World War I. She was recommissioned on 14 April 1941, prior to the United States entry into WWII, for use as a trainer. On 20 June 1941, she sank approximately Template:Cvt off Portsmouth, New Hampshire, with the loss of 33 lives. The wreck was located in 1997.

Design

The O-1-class submarines were designed to meet a Navy requirement for coastal defense boats.Template:Sfn The submarines had a length of Template:Cvt overall, a beam of Template:Cvt, and a mean draft of Template:Cvt. They displaced Template:Cvt on the surface and Template:Cvt submerged. The O-class submarines had a crew of 2 officers and 27 enlisted men. They had a diving depth of Template:Cvt.Template:SfnTemplate:Sfn

For surface running, the boats were powered by two Template:Convert NELSECO 6-EB-14 diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Template:Convert Electro-Dynamic Company electric motor.Template:Sfn They could reach Template:Convert on the surface and Template:Cvt underwater. On the surface, the O-class had a range of Template:Convert at Template:Cvt.Template:Sfn

The boats were armed with four 18-inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The O-class submarines were also armed with a single [[3"/23 caliber gun|Template:Cvt/23 caliber]] retractable deck gun.Template:SfnTemplate:Sfn

Construction

O-9Template:'s keel was laid down on 15 February 1917, at Fore River Shipbuilding Company, of Quincy, Massachusetts. She was launched on 27 January 1918,Template:Sfn sponsored by Mrs. Fanny Sherman,Template:Sfn the wife of Lieutenant Commander Frederick C. Sherman, the ships commanding officer while under construction,Template:Sfn and commissioned on 27 July 1918.Template:Sfn

Service history

During the final months of World War I, O-9 operated on coastal patrol and protected the Atlantic coast from German U-boats. She departed Newport, Rhode Island, on 2 November 1918, with a 20-sub contingent for Britain, in order to conduct her first war patrol. However, the end of the war came before O-9 reached Europe.Template:Sfn

After the war, O-9 continued in Naval service and trained submarine crews at the Submarine School at New London, Connecticut.Template:Sfn

When the US Navy adopted its hull classification system on 17 July 1920, she received the hull number SS-70.Template:Sfn

Proceeding to Coco Solo, Panama Canal Zone, in 1924, the boat was reclassified to a second-line submarine during her year there. Returning to operate at New London, O-9 reverted to a first-line submarine on 6 June 1928. Sailing up to Portsmouth, New Hampshire, in January 1930, the submarine returned to New London, in March; the following February, she sailed to Philadelphia Navy Yard, to decommission there on 25 June 1931.Template:Sfn

Remaining on the Naval Vessel Register, O-9 was recalled to training service as the US involvement in World War II became more inevitable. The 12 Template:Sclasss were already nearing completion and 73 Template:Sclass boats had already been ordered when O-9 was recommissioned at Philadelphia, on 14 April 1941, and went to New London on 31 May.Template:Sfn

In all, eight of the original ten O-boats were recommissioned to serve as training submarines in the Second World War. Template:USS had been sunk after a collision, in 1923, and Template:USS had been scrapped in 1938. O-9, in particular, required extensive work, and still suffered mechanical problems even after being returned to service.

Operational loss

On the morning of 19 June 1941, O-9 and two of her sisters, Template:USS and Template:USS, left as a group from the submarine base in New London, for the submarine test depth diving area east of the Isles of Shoals. Upon reaching their designated training area the following day, some Template:Cvt off Portsmouth, New Hampshire, O-6 made the first dive, followed by O-10. Finally, at 07:38, O-9 began her dive; the sub did not surface thereafter but was crushed by the pressure of the water over Template:Cvt below. The sub went down in the area where Template:USS had been lost.Template:Sfn

Rescue ships swung into action immediately. O-6 and O-10, submarine Template:USS, submarine rescue ship Template:USS, and other ships, searched for O-9, and divers went down from 13:00, 21 June, until 11:43, 22 June. Divers went to record depths for salvage operations but could stay but a brief time at the Template:Convert depth; but nonetheless set endurance and depth records for salvage operations until those operations were cancelled, as they were considered too risky. The boat and her 33 officers and men were declared lost as of 20 June. Template:Sfn

On 22 June, Secretary of the Navy Frank Knox conducted memorial services for the 33 officers and men lost on the boat. O-9 was struck from the Naval Vessel Register on 23 October 1941.Template:Sfn

Memorial

A commemorative plaque, listing the officers and men of O-9, is located at Albacore Park in Portsmouth, New Hampshire.Template:Sfn

In September 1997, the wreckage of O-9 was located, approximately Template:Cvt off of Portsmouth, at a depth of approximately Template:Cvt.Template:Sfn Sonar equipment from Klein Associates of Salem, New Hampshire, was used to find the submarine.Template:Sfn Her hull was seen to be crushed from just abaft the conning tower all the way to the stern, though the forward hull appeared intact. There are no plans to salvage O-9. Her exact location was disclosed only to the Naval Historical Center.Template:Sfn

In popular culture

In H. P. Lovecraft's short story The Shadow over Innsmouth, written in 1931, a US Navy submarine is described as firing torpedoes into the undersea habitation of Deep Ones, off the fictional Innsmouth, Massachusetts.Template:Sfn

More recently, and following Lovecraft's own pretense of presenting a pseudo-historical tale, Kenneth Hite and Kennon Bauman, have depicted the submarine as being O-9 in their book The Cthulhu Wars. In doing so, they presented the vessel's loss in 1941, as having been related to the fictional torpedo attack on the Deep Ones.Template:Sfn They even mentioned the actual commander of O-9 in 1927–1928, Lieutenant J. T. Acree.Template:Sfn
