PRP is the overarching solution to provide tactical, portable radios for the Navy (USN), Marine Corps (USMC), Air Force (USAF), Army, Coast Guard, and other Stakeholders. PRP provides portable radios with secure waveform capabilities and critical Satellite Communications (SATCOM) to meet the United States Military Services and Agencies requirements.
