My final task at MSubs was to design a new Seal Delivery submersible to replace the Northrop Grumman ASDS submersible that was lost in a fire whilst charging the battery. The first iteration I named 401 which was significantly larger than the final design. A smaller version was named S351 and one of its main design constraints was it had to fit into a 40ft shipping container.

I lead the design team through to the point where contracts with the US Navy were signed and the main pressure hull ordered from a supplier in Germany.  I understand three of these vehicles have so far been delivered.
