1.10.1. Protective Capsule Unit: PCU (NDH-316)
(1) Function:
The protective capsule unit (PCU) records navigation data, hull data, conversation in the bridge, conversation over VHF
radio, and radar image data to the recording medium in the PCU.
When submerged, the Underwater Acoustic Beacon with PCU, which is a battery-powered, transmits a pulsed acoustic
signal for capsule searchers.
