Earlier versions of torpedo were dropped from small altitude of 50 feet and with low speed 110 knots. It made torpedo airplanes very vulnerable to enemy’s fire. Also malfunctions were a great problem with early MK 13 version. Problems were solved during a war. Stabilizer fins were changed and plywood covers for tail section and warhead were introduced. Plywood covers reduced speed of falling torpedo and absorbed shock of hit of water surface. It increased drop altitude to 2000 feet and speed to  410 knots.

One thought on “US Navy Aerial Torpedo Mk XIII

  1. Phillip Ware says:

    Hi Wojtek,
    Is it possible to scale the torpedo MK XIII up to 1/48 scale for TBD-1 by Great Wall hobbies,
    And Revell’s Ventura. The TBD-1 is difficult to find as a torpedo bomber but your torpedo could be used to convert the Wake Island TBD-1 which is still quite numerous.
