Autogyros offered a limited route to shipborne submarine hunting

Could naval autogyros have been adapted for anti-submarine work and dipping sonar?

They could support local scouting and perhaps lightweight anti-submarine sensing, but the inability to hover and limited payload make dipping-sonar work difficult.

An autogyro can fly slowly and use a much smaller operating area than a conventional fixed-wing aircraft. Those qualities make it useful for local observation and potentially for carrying lightweight anti-submarine sensors from modest ships. It cannot hover like a helicopter, so operating a dipping sonar would require special procedures and favorable handling. The concept is therefore a transitional or niche solution rather than a direct substitute for the mature shipborne helicopter.
