The First Two-Channel Manpack Radio Connecting Soldiers To MUOS

The AN/PRC-155 Manpack radio is the U.S. Army’s first fielded two-channel, software defined radio that connects to the new Mobile User Objective Satellite (MUOS) network, providing soldiers with clear, smartphone-like voice communications wherever they are deployed. With two channels, the Manpack can run different waveforms simultaneously, eliminating the need for more than one radio at any location.

  • The first and only fielded, two-channel tactical radio that is proven to be MUOS ready
  • Supports multiple waveforms – SRW, WNW, MUOS, SINCGARS, and SATCOM
  • Bridges networks together – legacy to future, terrestrial to beyond-line of sight, lower to upper echelons, unclassified to classified
  • Creates self-forming ad hoc networks for vehicle mount or dismounted troops in any battlefield scenario

Product Details


General Dynamics uses a common core radio architecture, software and hardware design approach for all HMS products, including the Manpack radio. Special emphasis on SWAP-C (Size, Weight and Power Cost) lightens the soldier load and maximizes battery life through efficient design and both aggressive and intelligent power management. The Manpack includes GPS for position-location applications – painting individual units on a map to help reduce fratricide and increase situational awareness on the battlefield.

  • NSA certified for Top Secret and below communications
  • 2-channel networking radio with embedded encryption and GPS
  • Reconfigurable and interoperable with current-force and future radio platforms via a software upgrade
  • Creates self-forming ad hoc networks in any battlefield scenario
  • Extends the classified network beyond the path of vehicles

MUOS High Power Amplifier (MHPA)


The MUOS High Power Amplifier (MHPA) is an appliqué for the PRC-155 2-Channel Manpack radio. The MHPA replaces the standard High Power Amplifier (HPA) on either channel of the PRC-155 Manpack radio. With the MHPA attached, the PRC-155 Manpack radio becomes MUOS enabled providing a worldwide satellite-based communications capability, derived from 3GPP UMTS cellular technology. The route and retrans capability enables disparate networks, using legacy waveforms to be connected through the MUOS satellite system.

  • The PRC-155 Manpack radio is the first and only fielded, two-channel tactical radio that is proven to be MUOS ready
  • Crystal clear voice quality & virtually unlimited communications range
  • Dial-up voice calls to any other MUOS terminal or SCIP-enabled DISN (land line) phone worldwide
  • Data communications via any other MUOS terminal worldwide and access to designated SIPRNET or NIPRNET servers
  • Voice and data MUOS to Legacy Waveforms Route and Retrans (bridging)

The combination of the PRC-155 Manpack radio and MHPA provides dismounted soldiers voice and data communications while “on the move” using a lightweight, low-profile antenna. There is no need to stop, setup or position special antennas.
