The Bergall's Revenge The Silent Service : Season 2 Episode 3

Bergall (SS-320) American submarines had the job of ridding Lombok Strait of annoying Japanese patrol craft. With a homing-type torpedo that was effective against shallow draught boats, the USS Bergall was able to mete out punishment to the enemy patrols. But the new torpedo posed some problems for the submarine's skipper; it homed on noise and wasn't particular about whose noise it was. There was always the chance that the torpedo would make for the submarine instead of the enemy.
