Handheld, Manpack, and Small Form Fit

The Handheld, Manpack and Small Form Fit (HMS) family of software defined tactical radios are key to delivering legacy interoperability and networking capabilities to the mounted and dismounted warfighters. HMS radios enable cost-effective net-centric warfare to the individual soldier at the first tactical mile.

Product Description

JTRS HMS is a materiel solution meeting the requirements of the Office of the Assistant Secretary of Defense for Networks and Information Integration/DoD Chief Information Officer for a Software Communications Architecture (SCA) compliant hardware system hosting SCA-compliant software waveforms (applications). HMS is an Acquisition Category ID Program that encompasses specific requirements to support Special Operations Command, Army, Marine Corps, Air Force, and the Navy communication needs.

The Embedded Small Form Fit versions of HMS will be used for Joint Service Ground Sensor Networks, Intelligent Munitions deployment and usage, Unmanned Vehicles and other platform applications, including support for the Early-Infantry Brigade Combat Team technical performance and integration.

The JTRS HMS contract is structured to address Increment 1, consisting of Phases 1 and 2. Increment 1, Phase 1 will develop the AN/PRC-154 Rifleman Radio sets and embedded SFF-A (one channel), SFF-A (two channel) and SFF-D (one channel) versions. The AN/PRC-154 Rifleman Radio sets and SFFs will utilize the Soldier Radio Waveform (SRW) in a sensitive but unclassified environment (Type 2). In order to mitigate program waveform porting and integration challenges, the SRW application, which is managed by the JTRS Network Enterprise Domain, was developed on a Waveform Development Environment with HMS as the lead platform for porting.

Increment 1, Phase 2 will develop the two channel manpack, two channel handheld, and embedded SFF-B, versions that are all Type 1 compliant for use in a classified environment. Waveforms on the phased sets include Ultra High Frequency (UHF) Satellite Communications, Soldier Radio Waveform (SRW), High Frequency (HF), Enhanced Position Location and Reporting System (EPLRS), Mobile-User Objective System (MUOS), and Single Channel Ground to Air Radio System (SINCGARS).
