Why submarine homing torpedoes were hard to adapt for aircraft

Could a G7e-style acoustic homing torpedo have been air-dropped or surface-launched?

In theory, yes, but air entry imposed different shocks and hardening requirements; adaptations appear to have faced practical and timing problems.

The air-dropped Mark 24 mine shows that the broad homing-weapon idea was viable. A G7e-style torpedo, however, was hardened for submarine launch rather than a high-energy impact with the sea. Air entry imposed a different set of shocks and demanded changes to the weapon's structure and components. Adaptation appears to have been considered without producing a timely operational result, showing how launch environment can defeat an otherwise plausible transfer of technology.
