Northrop Grumman and Polish firm Transbit have integrated a non-US radio communications system with the Integrated Air and Missile Defense Battle Command System (IBCS).

The Transbit R-460A radio relay high-capacity line-of-sight (HCLOS) radio communications system was also tested.

The R-460A radio is the first Polish system and first non-US radio communications system to be integrated with IBCS.

Developed jointly by the US Army and Northrop Grumman, IBCS is a software-defined and hardware-enabled system. It is the future command and control system for US Army air defence assets.

It is managed by the US Army Program Executive Office for Missiles and Space, Redstone Arsenal, Alabama.

Poland is the first overseas partner nation to acquire IBCS.

The company is under a $713m contract to produce Integrated Air and Missile Defense (IAMD) Battle Command System (IBCS) for the first phase of Poland’s WISŁA air and missile defence programme.

Northrop Grumman combat systems and mission readiness vice-president and general manager Kenn Todorov said: “This successful integration is a testament to a strong industry partnership and sets the stage for future efforts to integrate other Polish and indigenous systems and capabilities onto the IBCS network.

“We look forward to continuing to work with Polish industry supporting their indigenous capabilities in support of the Polish defence modernisation programme.”

Northrop Grumman and Transbit partnered on the development of a laboratory prototype that included representative IBCS hardware, software components and a radio communication system that is based on the Transbit R-460A Radio Relay product.

Work on the prototype was carried out at Northrop Grumman’s facility in Huntsville.

Northrop said that the R-460A radio operates in the Nato Band IV frequency range and supports switched beam antennas use.

Last month, the US DoD approved low rate initial production (LRIP) of the US Army’s new battle command system IBCS.
