Before presenting the new submarine work, let's have a little side story. Inspired by the US Navy's S-3A carrier-based aircraft, I designed a similar model, which I named: S-7A.

The S-7A Anti-Submarine Fighter :
Wingspan:18.9m
Length:19m
Heigth:7.6m
Max speed:630km/h
Stallintg speed:160km/h

The work has been completed and will be released soon.
