The General Dynamics Mission Systems AN/PRC-155 MUOS-Manpack radio functioned as the communication center facilitating connections among soldiers stationed in the U.S. Army Pacific area and the Mobile User Objective System (MUOS) communication network. Numerous dual-channel AN/PRC-155 MUOS-Manpack radios, situated in and around the Hawaiian Islands, enabled troops to converse, exchange information, and uphold communications aboard Army vessels as well as in various terrestrial locations. Outfitted with a MUOS high-power amplifier and operating on the MUOS waveform, these radios permitted troops to share inbound mission command, forming a unified operational overview through the MUOS communication network among involved soldiers.

“This successful exhibition, coupled with the collaborative U.S. Army-Navy assessment conducted in November 2015, illustrates the military preparedness of the MUOS communications network and confirms that the AN/PRC-155 MUOS-Manpack radio is the exclusive radio capable of successfully linking military personnel with the innovative MUOS network in diverse operational environments,” stated Mike DiBiase, a vice president at General Dynamics Mission Systems. “As the Army prioritizes deployment locations for the AN/PRC-155 MUOS-Manpack radios, soldiers can confidently rely on it to ensure connectivity and pristine voice communications, regardless of their deployment location, especially in circumstances where geographical challenges severely obstruct network connectivity.”

Conducted within the Army Pacific zone of interest, the demonstration consistently validated how the AN/PRC-155 MUOS-Manpack radio utilizing the MUOS network delivered dependable and continuous communication connectivity, addressing a challenge for Army operations in remote and challenging locations.

By deploying the Manpack radios equipped with a MUOS applique together with the Joint Battle Command Platform (JBC-P) system, soldiers aboard a Logistics Supply Vessel (LSV) traversing between two islands were able to communicate and transmit data and images to their comrades in Oahu and Hawaii. Beyond maintaining continuous voice and data communication from the LSV to the mainland, commanders could track the vessel’s position using the JBC-P system. This exercise showcased how interconnected systems can deliver communication and situational awareness data to small units and USRPAC logistical operations.

The General Dynamics AN/PRC-155 MUOS-Manpack radio features a MUOS high-power amplifier that ensures the radio signal potency necessary for reaching MUOS satellites positioned in geostationary orbit. Utilizing both channels, the AN/PRC-155 serves as the connection point bridging different radios and waveforms employed by soldiers across a mission area. The AN/PRC-155 MUOS Manpack receives an incoming call from a tactical radio on one channel, processes and retransmits it on the second channel, directing it towards a satellite communication network, such as MUOS or other tactical communication systems.

As of now, 5,326 AN/PRC-155 Manpack radios have been delivered to the Army, offering secure line-of-sight and satellite communication connectivity for Army personnel stationed in areas where alternative communication networks are unavailable or obstructed.

The MUOS waveform acts as the digital dial tone linking personnel utilizing the AN/PRC-155 MUOS-Manpack radio with the MUOS communication network, facilitating seamless voice, text, and mission information exchanges. As the Army transitions towards a more deployable force, it is essential for soldiers to maintain connectivity to the network at all times, in every environment, and throughout all operational phases.

The Lockheed Martin-manufactured MUOS communications network provides military and government personnel with smartphone-like access to the network, ensuring voice clarity similar to the experience civilians enjoy while using their cell phones daily.
