ABSTRACT:
A submarine's mast and its protective closure are prevented from inadvertly damaging each other while deploying or retrieving the mast and while securing the closure. Interconnected logic circuitry electronically prevents an improper actuation sequence so that the mast and closure do not collide. Mechanical linkages and fail-safes susceptible to corrosion and damage are eliminated thereby permitting more reliable operation from circuitry safely stowed inside the submarine.
