Long story short:

• The deep-running problem was finally admitted to by BuOrd in August 1942, and fixes for this problem were issued to the fleet not long afterwards.
• Submarines under Lockwood's command began firing Mark 14's with the magnetic exploder (officially) deactivated in late June 1943. There never was a fix for getting the magnetic exploder to work properly.
• Mark 14s with a properly-functioning impact detonator first left for patrol at the very end of September 1943.
