I've received some pictures from Ellis Adams a
little while back on his S101 that you Subdudes likely have not seen. They are
here with some pictures I Took of the S101.

ID, 300 mm / 11.81102362" tall, 44 mm /
1.73228346" thick
This cylinder has to deal with the weight of the
steel weldment above it, collision, hydrodynamic and hydrostatic loads
.
This subs general operating depth is 100 meters / 305
