Proposed 221ft patrol and minelaying submarine (not built)
Scale 1:48. Plan shows the inboard profile of a proposed 221ft Patrol and Minelaying submarine (not built). This plan bears the signature of Sir Stanley Vernon Goodall [Director of Naval Construction 1936-1944]. This submarine appears to have been a derivative of the S-class submarines, but there is no evidence to suggest this was built or even ordered. The plan is noted as Sheet Number 1.
