American submarines underwent a number of modifications during the Second World War. These included changes to the gun armament, detection gear, electronics suites, and even the exterior appearance of the boats themselves. Pre-war Gatos and other classes, like the U.S.S. Salmon (pictured), started out with large, well-sheltered (for a submarine) conning tower fairwaters, with an …

It can travel forward or backward, or move laterally, but it must always remain on the single plane of the ocean’s surface. A submerged submarine, however, like an airplane, travels in three dimensions. In addition to the forward/reverse/lateral movement of …

In real life, both the submarine and the target are normally moving in different directions, and the captain …
