Harris has received a contract for the upgrade and maintenance of the US Department of Defense’s (Dod) joint tactical radio system (JTRS) programme soldier radio waveform (SRW), designed to provide wideband tactical communications in the battlefield.

Under the terms of the $26m indefinite-delivery indefinite-quantity (IDIQ) contract, the company will provide improved capabilities, maintenance and support services for the SRW for a period of five years to help the DoD improve and efficiently field the waveform in next-generation tactical radios.

Harris RF Communications Department of Defense business president George Helm said that the company would use its engineering and field expertise in wideband networking to help improve and evolve SRW to meet current mission needs, as well as emerging requirements.

”We will promote the highest standards of waveform portability and interoperability,” Helm added.

”In addition, we are also providing the Department of Defense with rights sufficient to invigorate competition, encourage innovation and accelerate fielding of radios running this important waveform."

Other key enhancements provided by the company will be placed in the JTRS programme information repository (IR), to enable software re-use in DoD tactical radios.

The SRW is a DoD voice and data waveform standard, developed as part of JTRS programme, to help extend battlefield internet protocol (IP) networks to the tactical edge in the battlefield.

Harris holds expertise in the performance of SRW, including waveform porting, testing, validation and certification, and has incorporated its AN/PRC-117G and AN/PRC-152A radios with the JTRS joint enterprise network manager to ensure interoperability with tactical radios developed by other companies.

In addition, the company’s Falcon III AN/PRC-117G manpack is NSA-certified for a type-1 implementation of SRW.

The two radios have already operated SRW during the US Army network integration evaluation (NIE) 12.2, conducted in May, at Fort Bliss in Texas and White Sands Missile Range in New Mexico, aimed to evaluate the army’s network architecture for capability set 13.
