A very small anti-submarine homing torpedo. Also known as the Mark 24 Mine and as "Fido." Homing was by four crystal hydrophones arranged around the body with simple guidance system that steered towards the loudest noise.
Fido was first used successfully by a British B-24 Liberator defending Convoy HX 237 on 12 May 1943, sinking U-456. This was followed by a USN PBY-5A from VP 84 which sank U-640 on 14 May 1943.
