You forgot how BuOrd spent *years* denying there could be a problem with USN torpedoes to the point where several complaining Captains were cashiered or transferred.
Malfeasance and penny pinching.
Naval Station RI only live fired one Mark 14 before the navy bought them.
The Mark 14 went through several upgrades, including a larger explosive charge, moving the gyroscope and all other manner of changes that changed the weight and weight distribution of the torpedo. And then only one test of a torpedo with a dummy load instead of the heavier torpex.
Fortunately some pretty respected Admirals screamed all the way to the top and things got changed.
Pinching pennies cost more than it saved.
