Journeyman Communication Course (JCC)

The MRTS 3D® JCC simulation system, now known as the Surface Ship Radio Room (SSRR), provides training for U.S. Navy Sailors entering the radio communications field and Information Systems Technicians (ITs). Training scenarios includes radio circuit operation, system fault isolation and troubleshooting, voice and data validation for radio circuits/components, and restoration of defective circuits/components. It is modeled after the naval communications systems on AEGIS-class ships, such as the DDG116 USS Thomas Hudner and the DDG-120 USS Carl M. Levin.

Most of the U.S. Navy surface ships in the fleet contain the same core radio equipment. The radio rooms contain equipment that provides communications via Over the Horizon, Line-Of-Sight (LOS), and Satellite. Standard naval radio operations include Medium Frequency (MF), High Frequency (HF), Ultra High Frequency (UHF), Super High Frequency (SHF), and Extremely High Frequency (EHF) communication.

JCC supports training scenarios for 18 Radio Circuit Setup Procedures, 71 Core Fault Isolation and Circuit Restoration Use Cases (with 151 total Fault Use Case permutations), 20 total Power On and Power Off procedures, and two Automated Digital Network Systems (ADNS) Cutover procedures.
