Ric,
I like a challenge, so I took you up on your offer concerning the photo
of the S-2 with her bow out of the water on your "Looking Glass" page.
I did a little research and discovered that the bulbous tank at S-2's
bow was not original equipment. Apparently, Simon Lake was concerned about
her seakeeping qualities and decided that a bow buoyancy tank would solve
the problem. The Bureau refused to let him modify the boat during construction
so that the prototypes S-1, S-2, and S-3 could be evenly compared during
trials.
( all built by different shipyards ) After
the trials completed, the Bureau relented and allowed him to make the modification
in (according to Norman Friedman) "about" 1921. (
Norman Friedman's outstanding work U.S. Submarines Through 1945: An Illustrated
Design History )
One other clue jumped out at me when looking at the photo. On the other
side of the pier, just to the left of the enclosure, is the conning tower
of the USS(?) U-111, a German U-boat taken over by the USN for study. After
an extensive series of trials, it was decommissioned (again according to
Friedman) in April, 1920. ( S-2 was commissioned
May 25, 1920 )
I also could not find any reference (yet) of the S-2 ever having accidentally
sunk alongside.
Given these facts, I am speculating that this photo was taken shortly
after the completion of the BBT mod in 1921 and this was an alongside static
dive to test the tank's operation and integrity. This also jibes with the
boat's large up-angle in a shallow water dive.
Strangely, the only fact that doesn't fit is the U-111's presence in
the photo. If she was decommed in April, 1920, why is she still around
in 1921? Either she wasn't immediately disposed of (I haven't been able
to find a date for that yet), or one of Friedman's dates are wrong.
( U-111 was sunk as a target in the Atlantic
in July of 1921 )
What do you think?
See ya
