Latest revision as of 11:31, 5 September 2023
This photo was taken in June 1926 during the initial lifting phases of the S-51's wreck. All of the sub's internal compartments except one (the battery room) had been closed up and dewatered. Pontoons had been attached via chains to several points on the S-51's hull and these were used to provide the extra buoyancy needed to get the boat to the surface. The first lift attempt did not go well and several of the pontoons slid out of position and the team needed to try again. In this photo the very tip of the S-51's bow can be seen above the waterline as the salvage crews scramble to stabilize the unwieldly pontoons.

Her stern torpedo tube can be seen just above the rudder, which is turned to starboard. Her starboard side stern diving plane is turned to full rise, likely due to the salvage operations.

This photo shows the reason for the S-51's loss. The steamship City of Rome struck her on the port side in the battery compartment at approximately a 45 degree angle from astern. S-51 was a double hull boat, meaning that she had an outer hull wrapped around the inner pressure hull, with the void spaces between the two hulls making up ballast and fuel tanks. The City of Rome struck the boat hard enough to penetrate both of the hulls. The impact must have been tremendous.
