Atlantic Ocean
  • Just 17 months after the first conceptual meeting for an acoustic homing torpedo, the Mark 24 FIDO aerial torpedo had its first operational victory when a Liberator bomber of RAF Coastal Command’s 86 Squadron caught German submarine U-456 on the surface in the mid-Atlantic. As the submarine dove, the bomber dropped one Mark 24 torpedo that guided itself to the submerged submarine and exploded, causing major damage. Later that same day when U-456 was forced to dive deep to avoid a depth charge attack by destroyer HMS Opportune, the previous damage proved too great and the submarine sank with all 49 hands. ww2dbase [B-24 Liberator | Black May | Mark XXIV | DS]
