S-2

USS S-2 (SS-106)

Photo in the private collection of Ric Hedman.

S-2 surfacing after a diving test alongside the pier at Portsmouth Navy Yard, Kittery, ME., spring or early summer 1921. S-2 had just been modified by her builder Simon Lake to correct a deficiency shown during trials where she had a tendency to burrow into the waves while running on the surface. She lacked reserve buoyancy forward. Lake added a buoyancy tank above the main deck at the bow in an attempt to correct this problem. This was not a common feature of U.S. submarines, but it is reminiscent of several British designs. Just visible in the background on the other side of the pier is the German U-boat U-111. It was surrendered to the Allies at the end of WWI and turned over to the U.S. for testing and evaluation. It was sunk as a target in the Atlantic in July 1921.

A special note about this photo: An email correspondence on July 7, 2001 about this photo was the beginning of a 20+ year friendship between the webmasters of this site, Ric Hedman and David Johnston.

• These photos show S-2 in drydock in Tsingtao, China, mid 1920's. Her raised bow buoyancy tank, torpedo tubes, anchor, and bow planes are visible here. The second photos shows both the motor room and engine room hatches open. All photos are provided from the private collection of the late Rick Larson.
