In order to minimize danger to the submarine and the aircraft during flight operations—which required ''Ettore Fieramosca'' to loiter on the surface while the aircraft was being assembled or disassembled—the aircraft also had to be designed so that it could be assembled quickly for flight operations and disassembled quickly after recovery for stowage in its hangar.

Operational history

The M.53 was among various small seaplanes considered for use aboard ''Ettore Fieramosca'', which was commissioned in 1930. None of the aircraft were deployed aboard the submarine, and ''Ettore Fieramosca''s hangar was removed in 1931. Italian submarine ''Ettore Fieramosca''
