The Convair Submersible Seaplane (or "Subplane") was a United States Navy project to produce a seaplane which could travel underwater as well as fly. In 1962 or 1964, the Navy granted a contract to Convair, a military aircraft arm of General Dynamics, to design and develop the vehicle, intended for anti-submarine warfare. The craft's operational deployment would be to scout for enemy submarines from the air and, when detected, land on the water, submerge, and engage them underwater. One envisioned deployment was to attack shipping in the Soviet Union's marginal seas – the Baltic, Black, and Caspian seas.
