|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 separate maneuvering 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.

|578k||Commissioned at Bridgeport, S-49 (SS-160) remained there through July, and, in August, moved down to the Submarine Base at New London where she joined Submarine Division Zero, composed of units engaged in submarine research and development. Later reassigned to Division 4 and then to Division 2, she continued experimental work, including aerial visibility tests and torpedo development, and also participated in regularly scheduled exercises, primarily in the New London area, into 1926.

"These submarines have probably made their last sea trip. The "Sub" S-49, with part of her conning tower and after deck showing, is seen at lower right, and the "Sub" S-50 (SS-161), airing her flags, at the end of Pier 3, Philadelphia Navy Yard. They arrived last week from New London, Conn. They are sister craft of the S-51 (SS-162) which was rammed and sunk by a steamer at night off Block Island in September 1925, with the loss of thirty-three members of its crew. The new arrivals will be put out of commission. One of the Navy Yard's huge traveling cranes is showing in upper left of photograph."

Francis J Chrestensen arrived in Toronto yesterday aboard his one-time U.S. navy submarine; and his wife arrived by automobile. He admitted he didn't know anything about underwater craft until he bought his own. She insists she'll never know about them; follows him everywhere by car. The submarine cruised across Lake Ontario yesterday to come to rest at the foot of York St.; where it was welcomed by this crowd. It cost $2;500;000 when it was constructed 17 years ago. The 240-foot submarine was commissioned by the U.S. under the London naval agreement. It was once able to fire $6;500 torpedoes from four tubes. Should Capt. Chrestensen take it into his head his ship could go down 300 feet below the surface with ease.||Photo i.d. courtesy of Ric Hedman.
