S-49 (SS-160)

S-48 Class Submarine: Laid down, 22 October 1920, at Lake Torpedo Boat Co., Bridgeport, CT.; Launched, 23 April 1921; Commissioned, USS S-49 (SS-160), 5 June 1922, at Bridgeport, CT.; Decommissioned, 2 August 1927, at Philadelphia Navy Yard, Philadelphia, PA.; Laid up in the Atlantic Reserve Fleet, League Island, PA; Struck from the Naval Register, 31 March 1931; Final Disposition, sold for scrapping, 25 May 1931, to Boston Iron and Metal Co., Baltimore, MD.

Following repairs, S-49 (SS-160) resumed operations off the New England coast; and, during January of 1927, moved south with S-50 (SS-161), for exercises and tests off Key West, the Dry Tortugas, and in Tampa Bay, Florida. On 12 March, S-49 returned to the United States Naval Submarine Base at New London/Groton, Connecticut...whence she completed a run to the Portsmouth Navy Yard at Kittery, Maine; and back to New London/Groton...then transited to the Philadelphia Navy Yard at Philadelphia, Pennsylvania, with S-50, for inactivation. Arriving on 31 March, S-49 was decommissioned on 2 August 1927 and berthed with other reserve ships in the Back Channel of the Philadelphia Navy Yard...until struck from the Navy List on 21 March 1931...in accordance with the London Treaty. S-49 was sold to the Boston Iron and Metal Company at Baltimore, Maryland, on 25 May 1931. Reduced to a hulk (read "demilitarized") by that company in 1936, but not scrapped, the S-boat was sold to an organization that operated the submarine as an "attraction." The submarine visited many ports in the United States and was "inspected" by interested people who toured through that submersible when she was open to visitors.

During the Second World War, the former S-49 was reacquired by the United States Navy "as equipment" for use in experimental work at the United States Naval Mine Warfare Test Station at Solomons, Maryland...now known as the United States Naval Air Station, Patuxent River...Solomons Facility. Shortly after being towed to Solomons from Baltimore (where the Navy had reacquired the submarine), the former S-49 foundered off Point Patience in the Patuxent River on 16 December 1942 and sank in 102 feet of water at: Position: Latitude 38 Degrees 19' 53.2" North Longitude 76 Degrees 29' 17.2" West or, on a bearing of 318.5 Degrees True, distant 525 yards, from the southern tip of Point Patience. The S-boat has remained on the bottom at that position to the present day...and is visited, on occasion, by Navy and recreational divers.

163k	S-49 (SS-160) was a Lake-built government-type *S-boat, modified while under construction to incorporate a single after torpedo tube. Note also the gun access trunk forward of the conning tower fairwater, which replaced the ready ammunition stowage of the first series of "government" S-boats*. She was lengthened to 240 feet to provide both a maneuvering room & a torpedo room aft. Displacement increased from 876 tons (surfaced) / 1092 (submerged) to 903/1230. Note the blister of the passive MV system forward, just under the circular patch of her Fessenden oscillator. Also note the seperate manuvering room inserted between the engine room & the after torpedo room, above the motors. The entire battery is forward, under the space between the forward torpedo room and the control room. Note the kinked (discontinuous) pressure hull, with large diameter sections at the ends, which require heavier & more elaborate structure to support it.	Drawing by Jim Christley.
