USCG ALC Avionics and C4ISR Program Support

The United States Coast Guard (USCG) Aviation Logistics Center (ALC) provides total lifecycle management and overhaul services to more than 200 Department of Homeland Security aircraft systems.  Rapidly-evolving C4ISR requirements driven by new Homeland Security Missions require central engineering and technology support to achieve logistics efficiencies and common system support.

CDS2 provides communications engineering, Combat ID, and TEMPEST services to the Engineering Services Division of the USCG ALC.  The RT-5000 was a commercially available radio set that required significant modification to meet USCG-specific frequency, Guard Monitoring, DCS Channel 70, and surface force/first responder interoperability requirements.  We performed extensive engineering studies and prototype testing in the laboratory, in flight, and in high VHF interference areas to verify system component performance and validate functional performance of the integrated system.  CDS2 provided an integrated test plan for the H-60 and H-65 rotary-wing programs to validate the proper communications operation of the RT-5000 (5011 and 8211) against known and reported integration discrepancies. 

Our team also provided technical support for one of the very first Mode 4-to-Mode 5 combat ID transitions.  Working closely with the AIMS Program Office and Raytheon, the manufacturer of the APX-119 transponder, we developed requirements and provided aircraft integration support for the MH-60T platform and delivered a fully functional, successfully tested, Mode 5 integration combat ID system.  As a result of our  efforts, all aircraft are within the designated TEMPEST profile and combat ID systems are successfully transitioning to Mode 5 capability.  All aircraft are COMSEC tested prior to release from overhaul to validate critical communications system functions, and a number of fleet-common systems have been developed, reducing total life cycle cost.
