INT-9602 High Data Rate Antenna (HDR) Hydraulic Control Unit


The INT-9602 was built for U. S. Navy Los Angeles class attack submarines to control the hydraulics for the antenna mast of an enhanced EHF communications system. The communications system was developed by NSWCCD-SSES at the Philadelphia Naval Shipyard.

The INT-9602 accepts commands from the Ballast Control Panel (BCP) to raise and to lower the EHF mast. Its embedded processor accepts the commands, validates the mast and door positions, and energizes solenoids to control the hydraulic valves. It was built and tested to the very demanding requirements of the Navy for deployment into the United States Nuclear attack submarine fleet.
