Crash and Fire Protection
The Crash Survivable Memory Unit (CSMU) is designed to fully meet the 5,000
pounds crush test requirement of TSO–123a and provides impact protection for up
to 3400 g’s for 6.5 msec. The inner steel casing assembly protects the memory ele-
ments from deep sea pressures to 20,000 ft.
