Shock isolation protects submarine batteries and auxiliary machinery

T-class experience showed that hull-transmitted shock could threaten batteries and other systems unless their placement and mountings isolated them from the pressure hull.

Question

Why were T-class submarine batteries and auxiliary systems vulnerable to shock, and how could designers protect them?

Short answer

Hull-transmitted shock reached their mountings, so designers needed to isolate or raft sensitive equipment from the pressure hull.

Notes

T-class battery vulnerability exposes the wider problem of shock reaching auxiliary equipment. Placement matters because a pressure hull transmits vibration and impact through rigid connections. Isolation reduces that transfer into sensitive machinery during battle damage. The same rafting principle works in the opposite direction by keeping machinery vibration and noise from escaping through the hull.
