USS O-6 (SS-67), also known as "Submarine No. 67", was one of 16 O-class submarines of the United States Navy commissioned during World War I. She was recommissioned prior to the United States entry into WWII, for use as a trainer.

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 NELSECO 6-EB-14 diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Electro-Dynamic Company electric motor.Template:Sfn They could reach on the surface and Template:Cvt underwater. On the surface, the O-class had a range of 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-6Template:'s keel was laid down on 6 December 1916, by the Fore River Shipbuilding Company, in Quincy, Massachusetts. She was launched on 25 November 1917,Template:Sfn sponsored by Mrs. Carroll Q. Wright,Template:Sfn and commissioned at Boston, Massachusetts, on 12 June 1918.Template:Sfn

Service history

World War I

The United States had already entered World War I by the time O-6 was commissioned, and she operated from Philadelphia, Pennsylvania, on coastal patrol along the East Coast, hunting Imperial German Navy U-boats from Cape Cod, in Massachusetts, to Key West, in Florida.Template:Sfn

O-6 was the target in a friendly fire incident in the Atlantic Ocean, in August 1918. On 6 August 1918, she departed Hampton Roads, Virginia, as one of the escorts for a convoy of five troop transports. With orders to escort the convoy for one day, she followed the convoy on the surface at a distance of , maintaining a speed of . During the night of 6–7 August, she lost sight of the convoy in the darkness. After sunrise on 7 August 1918, she followed the expected track of the convoy, expecting to catch up with it. On the afternoon of 7 August, she sighted ships ahead which she assumed belonged to the convoy she was escorting. After following the ships for 15 minutes, she realized that they did not belong to her convoy and that she was in fact following a convoy of 28 cargo ships. At 15:00, when she was about to turn away and head for port at the Delaware Breakwater, in accordance with her orders, the last ship in the convoy, the American armed cargo ship , which was slightly behind the rest of the convoy's ships, sighted her and mistook her for a German submarine with a mast and sail set. US Navy gunners aboard Jason opened fire on O-6 with JasonTemplate:'s gun at a range of . Jason fired eight rounds, scoring five hits. After the first hit, O-6 attempted to dive, but the second hit struck her conning tower and started leaks that made it impossible for her to submerge. O-6 blew her ballast tanks and returned to the surface. She flashed recognition signals by blinker light and members of her crew waved a United States flag on her deck. Jason reported that O-6 fired six shots from her deck gun at Jason, apparently misinterpreting O-6Template:'s recognition signals as gun flashes. Another of the convoy's cargo ships also opened fire, and shell splashes from that ship's gunfire fell short of O-6, this may have appeared to JasonTemplate:'s crew and gunners to have come from O-6. O-6 stopped, and Jason ceased fire as she steamed out of range of O-6. One of the convoy's escorts, the US Navy destroyer , had meanwhile, reversed course and approached Jason, which signaled that she had a submarine in sight. Paul Jones then closed with O-6 and opened gunfire, but all of her shots fell short, and she ceased fire when she closed to a range of and saw that O-6 was flying a US flag from her conning tower. Paul Jones came alongside O-6 to render assistance. O-6 suffered no casualties, but she had sustained serious damage, including to her compasses, which had been knocked out, and her steering gear. Paul Jones escorted her to port at the Delaware Breakwater, where they arrived on 8 August 1918.Template:Sfn

O-6 received a commendation for her crew's conduct during the incident. Lieutenant Wright was promoted to lieutenant commander on 15 August 1918, and later was awarded a Navy Distinguished Service Medal, the citation for which says, "The courage and coolness with which Lieutenant Commander Wright handled his vessel under these very trying conditions undoubtedly saved the ship and crew." In his report of the affair to United States Secretary of the Navy Josephus Daniels, O-6Template:'s submarine division commander wrote, "It is believed that recognition should be made of the exceedingly efficient gunnery work of the merchant vessel in question, in that she got on so quickly, and held a difficult target under the circumstances of possible enemy attack." Jason at first was misidentified as a British merchant ship, but her actual identity later was established. Her gun crew had fired with great accuracy at long range, and the commander of her Navy gun crew was awarded a Navy Cross, the citation crediting Jason with an engagement with an enemy submarine.Template:Sfn

On 2 November 1918, O-6 departed Newport, Rhode Island, in a 20-submarine contingent bound for service in European waters. but the armistice with Germany of 11 November 1918, brought World War I to an end before the submarines reached the Azores. They returned to the United States.Template:Sfn

1919–1941

After World War I, O-6 operated as a training ship from Naval Submarine Base New London at Groton, Connecticut.Template:Sfn When the US Navy adopted its hull classification system on 17 July 1920, she received the hull number SS-67.Template:Sfn Reclassified as a second-line submarine on 25 July 1924, while stationed at Coco Solo, in the Panama Canal Zone, she reverted to first-line status on 6 June 1928, and continued to operate from New London, until February 1929, when she proceeded to Philadelphia. She was decommissioned there on 9 June 1931.Template:Sfn

As US involvement in World War II approached, the US Navy (USN) began to recommission old submarines for use as training ships. O-6 recommissioned at Philadelphia, on 4 February 1941, then returned to New London, to train students at the Submarine School. On 19 June 1941, she made a trial run to Portsmouth, New Hampshire. The next day, the submarine sank Template:Cvt off Portsmouth. O-6 joined the submarines and and other vessels in the search for O-9, but to no avail.Template:Sfn

World War II

O-6 remained in the Portsmouth area.Template:Sfn The United States entered World War II on 7 December 1941, and she carried out training duties from Portsmouth, through the end of the war, which concluded with the surrender of Japan on 15 August 1945.

Fate

O-6 was decommissioned at Portsmouth, on 11 September 1945. She was struck from the Naval Vessel Register the same day, and was sold to the John J. Duane Company, of Quincy, Massachusetts, on 4 September 1946. She was scrapped in December 1946.Template:Sfn
