Damage Control Wirefree Communications (DCWIFCOM)


The Damage Control Wire Free Communications (DCWIFCOM) system consists of an antenna system, portable radio transceivers, base stations and scanners which provide a fast, flexible and survivable means of rapid communication between Damage Control Central (DCC) and Damage Control Repair Stations (DCRS). Where installed, DCWIFCOM is the primary means of communication within the DCRS area of responsibility. DCWIFCOM was originally installed on the following ship classes:

  • DDG-51 Class

  • CG-47 Class

  • FFG-7 Class

The DCWIFCOM transceivers are multi-channel, two-way handheld radios which allow real time, instantaneous communications between repair stations. The radios are used by repair party personnel for command and control information and coordination in and around the casualty scene area. They are also used by DCTT members and training teams for coordinating and implementing drills. The radiating antenna cable (RADIAX) is used as a transmission line through the hull of the ship.

Damage Control Central (DCC) has the base station which can access all channels and has the ability to talk to any DCRS. This allows DCC to receive not only each repair station’s report, but all repair station scene leader reports directly. Each repair station has an installed base station and four portable handheld transceivers. Four to twelve channels are available, with the first four channel assignments as follows:

  • Channel 1 DCRS 5

  • Channel 2 DCRS 2

  • Channel 3 DCRS 3

  • Channel 4 Ship-to-Ship and DC repair station to DC repair station.


Each repair station has a primary and secondary channel. Primary channels are for the individual repair station communications such as between the DCRS and OSL/Investigators. Secondary channels are used to communicate between repair stations and DCC, as well as ship-to-ship.

Personnel using DCWIFCOM need to be aware of specific zones of reduced transmission capability or “Dead Zones”.
