Grumman developed small manned submersible vehicles in the late 1960's to meet a growing demand for these craft in both military and commercial applications. The first was the PX-15 "Ben Franklin," followed by this development of the same concept, the GSV-1. Unlike the PX-15, no operational example of the GSV-1 was ever completed.
