Okay, here's some "amplifying" info. on that sub. I managed to take two pictures, which (using a 50MM<?> lens from 1000 feet) don't show much. Anyway, there are two "dive planes" halfway up the conning tower right at the leading edge. Also, there's some kind of a projection or bulge off the rear of the conning tower near the top. Two periscopes<?> are visible on top of the conning tower, too.
