Submarines, Inc. & Associated Firms. U.S. Submarines, Inc. founded in 1993. The company developed the concept of. the personal luxury submarine and has also designed deep submersibles for. marine science research, diesel electric submarines, tourist submarines with both. steel and transparent acrylic pressure hulls; military patrol and surveillance.

For example, the Ohio class (Trident) submarines are almost 2 football fields long, 7 stories tall from keel to sail, and wide as a 3 lane highway.
