Northrop Grumman has demonstrated its gallium nitride (GaN)-based Lower Tier Air and Missile Defense Sensor (LTAMDS) to the US Army.

Northrop Grumman has demonstrated its gallium nitride (GaN)-based Lower Tier Air and Missile Defense Sensor (LTAMDS) to the US Army.

The demo of the in-production solution was conducted during a two-week open ‘Sense-Off’ competition at White Sands Missile Range in New Mexico, US.

Northrop Grumman is one of four companies working on design contracts for the army’s LTAMDS programme, which is seeking to replace the Patriot AMD radar.

Northrop Grumman land and avionics C4ISR division vice-president Christine Harbison said: “Our mature, GaN-based design demonstrated an advanced system with our current capabilities aligned with the army’s requirements.

“Our solution supports the need for rapid deployment with an architecture that allows for significant margin of capability growth to protect our warfighters today and in the rapidly changing threat environment.”

The system will deliver a 360° full-sector mission capability to the US Army and be able to meet current and future needs of troops.

It is designed to meet the army’s top requirements, including speed to field.

Northrop highlighted the need for an embedded logistics capability to facilitate faster and affordable modernisation and better sustainability over the lifecycle of the LTAMDS programme.

To develop the solution, the firm leveraged its expertise in sea, land, air and space-based military radar technology and high-performance microelectronics.

“Our solution supports the need for rapid deployment with an architecture that allows for significant margin of capability growth.”

The LTAMDS offering is incorporated with GaN high-power density radio frequency components for greater performance.

Northrop Grumman now plans to deliver its final LTAMDS proposal to the army in the next few weeks for evaluation.

The US Army intends to invest around $1.5bn over the next five years to develop the new Patriot air and missile defence radar under the LTAMDS programme, Jane’s reported in March.

Last month, Raytheon completed technical testing of its solution during the US Army’s LTAMDS Sense-Off.

The other two companies participating in the programme are Technovative Applications and Lockheed Martin, according to DefenseNews.
