Small Form Fit Joint Tactical Radios exceed expectations in quantitative government field tests.

The General Dynamics C4 Systems Handheld, Manpack and Small Form Fit (HMS) radios have demonstrated their critical networked-communications capabilities in recent government-run Joint Tactical Radio System (JTRS) field tests. The tests have proven the radios’ interoperability, range, video transmission and networking abilities. Each of those capabilities is critical to accomplishing the Department of Defense’s transformational objectives of increasing connectivity among warfighters and military units.

General Dynamics C4 Systems, a business unit of General Dynamics (NYSE:GD), is the prime contractor for the JTRS HMS program.

“The results of these tests validate that JTRS HMS will transform the battlefield by bringing secure wideband communications and situational awareness to dismounted soldiers at the front of the fight,” said Army COL Daniel Hughes, Ground Domain program manager for the Joint Program Executive Office JTRS.

Characterized by their small, light and power-efficient design, HMS radios work for close-combat tactical communication and are easier for soldiers to carry or wear compared to currently deployed legacy radios. They can also be embedded in new lightweight sensors, robots and unmanned aerial vehicles. The HMS radios all have the same core design but take on different functionality and physical shape depending on the unique mission.

The HMS radios are setting a new standard for meeting battlefield-networking requirements compared to all other available radios. A recent field experiment at Ft. Huachuca, Ariz., for example, featured a 2-channel Manpack HMS radio exceeding a 20-kilometer range requirement test and transmitting voice and data over rugged terrain and rough conditions. The Manpack HMS radio is also part of an ongoing field experiment in Lakehurst, N.J. Using the new, highly-advanced Soldier Radio Waveform to uniquely format information, the Manpack HMS radio successfully has transmitted voice, video, data and messages to 25 nodes simulating soldiers operating within a single network.

The HMS radios also are achieving other key JTRS requirements, such as communicating with existing, widely used Single Channel Ground and Airborne Radio System (SINCGARS) radios, transmitting video while embedded in unmanned aerial vehicles and communicating with radios mounted in mobile ground vehicles.

The JTRS HMS 1-channel radio for ground soldiers, the Small Form Fit – C (SFF-C) Version 1, or “Rifleman Radio,” is scheduled for user evaluation by the U.S. Army’s Evaluation Task Force at Fort Bliss, Texas, next month.

General Dynamics will demonstrate the HMS radios’ networking capability at the Association of the United States Army Conference in Washington, D.C., in early October.
