Mark 27 Torpedo

The Mk 27 Mod 4 torpedo is located in the waiting area for the USS Cobia tours.

The Mod 4 was a refinement of the Mk 27 Mod 0, which in turn was an adaptation of the Mine Mk 24. The mine was 19" in diameter but submarine torpedo tubes were 21" in diameter, so the torpedoes were fitted with wood guides on the outer cylinder shell.
