Project 765 to become SMV SeaHawk

Submarine Build and Launch

John Kammerer is fulfilling a lifelong dream by building a private submarine for recreation and exploration. Currently dubbed Project 765, the vessel will be christened SMV SeaHawk.

When completed the submarine will be 65 feet long with a beam of 6 feet 10 1/2 inches. Displacement will be 42 tons surfaced, 48 tons submerged. Power is diesel-electric direct. See the Specifications page for more details.

Most of the design work is being done by Kammerer, with assistance from specialists as required. Primary builder is Kammerer.  Additional expertise and support is contracted as needed, including specialized subassemblies, specialized welding and other processes. On this website you can view progress of the project with lots of photos; start on the Build page. Be sure to check back often. We will continue to add photos as the project progresses.

One of the most universal questions we get is Why? The first post in the Captain’s Log blog has just that title and explains: Why?
