Each new aircraft generation changed the speed, altitude, airflow, and release conditions experienced by its torpedo. A successful drop from an earlier type therefore could not certify the same weapon for a newer and faster carrier aircraft. The obstacle was a peacetime funding choice because thorough trials can look like excessive caution when budgets are tight. Accepting that risk saves money only until war exposes a defect under fire. Repeated realistic testing could have found the Mark 13's integration problems before aircrews depended on it in combat.

Peacetime torpedo testing bought wartime reliability
Every aircraft generation required realistic weapon recertification, even when peacetime budgets encouraged leaders to accept the risk of relying on old test results.
