L3Harris Technologies is set to replace legacy radios used by the US Army with advanced tactical systems.

This comes after the US Army selected L3Harris as one of the two vendors for a $6bn indefinite-delivery, indefinite-quantity (IDIQ) contract under Combat Net Radio (CNR) modernisation programme.

The contract includes a five-year base period and an option to extend it by additional five years.

Currently, the US and other allied forces use the Single Channel Ground and Airborne Radio System (SINCGARS) radio.

L3Harris is a supplier of SINCGARS systems and has delivered more than 300,000 units to the US Department of Defense (DoD) since the 1980s.

The CNR programme seeks to replace a ‘significant portion’ of the US Army’s ageing SINCGARS radios with a new system that will enable military communication in all environments.

Under the contract, L3Harris will deliver modern SINCGARS systems that offer advanced NSA-approved encryption and resilient waveform communications for the Integrated Tactical Network (ITN).

The company has already received an initial delivery order worth $20m.

L3Harris Communication Systems president Dana Mehnert said: “Upgrading to a modern voice and data SINCGARS Combat Net Radio capability will be seamless with our drop-in replacement for currently fielded dismount systems, vehicular platforms, air defence and artillery systems.

“With our next-generation radio, soldiers can leverage existing training, installation kits and system integration – with zero down time – to get improved mission readiness.

“We are honoured to provide the US Army’s ITN with a critical communications capability well into the future.”

L3Harris Technologies is an aerospace and defence technology company based in the US.

Last week, the company posted its first quarter results. It recorded a revenue of $4.1bn in Q1 2022, down 10% from last year same period.
