During the early war period, one of the flaws of the Mk.14 was the contact portion of the exploder. The BuO stuck the same exploder from earlier torpedoes on the new Mk.14. The problem was, they never took into account the faster speed of the new Mk.14 At a perfect 90* impact at high speed, the inertial forces were so great, the firing pin fractured, causing a "dud". Captains were noticing that impacts at less than ideal angles were resulting in "hits". This was because at those angles, (and consequently slower speeds) the inertial force was reduced enough to keep the firing pin intact.
