Specialist defence firm Ultra yesterday said that its Tactical Communication Systems business in Montreal, Canada has clinched an initial £7.47 million deal to supply enhanced tactical radios to the US Army for the Patriot air defence missile system.

Ultra, which has a major facility at Rugeley, said the contract was awarded by the Canadian Commercial Corporation acting on behalf of the US Department of Defense.

The company will supply an upgraded version of its High Capacity Line of Sight (HCLOS) radio that is the baseline for the Joint Network Transport Capability (JNTC) programme, providing wideband communications for use by the US Army.

The HCLOS radios and associated equipment are key elements of the US Army's transformation of its battlespace information management process.

The firm's radio communication systems provide secure battlefield trunk telephone and telecommunication services to link battlefield commanders and their forces.
