7. Failure to Adequately Test a Theoretically Promising Weapon

Unfortunately, the Mark 14 was designed at the height of the Great Depression, when money and military budgets were tight. Between frugality and secrecy, no live Mark 14 were conducted. The magnetic detonator upon which great hopes rested had been live tested only twice on older torpedoes in the 1920s. In one of the two tests, the detonator had failed to go off. A 50% test failure rate did not prompt the US Navy to conduct additional tests. Despite the fact that it had fared miserably in the few live fire tests conducted, the magnetic detonator to be used on the Mark 14 Torpedo was approved for use by the US Navy’s Bureau of Ordnance.
