Northrop Grumman Demonstrates Its Solution for U.S. Army’s LTAMDS Program

Northrop Grumman has announced that the company demonstrated its in-production solution for the U.S. Army’s Lower Tier Air and Missile Defense Sensor (LTAMDS) program during an open “Sense Off” competition.

The “Sense Off” event was conducted at the Army’s White Sands Missile Range (WSMR) in New Mexico from May 16 to June 1.

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

Northrop Grumman’s LTAMDS solution demonstrated a mission capable system with growth potential leveraging advanced, affordable, low-risk, in-production and fielded technologies from across the company’s active electronically scanned array (AESA) portfolio. The company’s offering is the latest Northrop Grumman sensor product to incorporate and use GaN high power density radio frequency components for greater performance. The system provides a 360-degree full-sector mission capability.

Northrop Grumman’s offering is reportedly based on the AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) which recently completed Initial Operational Test and Evaluation (IOT&E) with the U.S. Marine Corps (USMC). This new advanced, multi-mission Active Electronically Scanned Array (AESA) radar is the Marine Corps’ next generation Air Surveillance/Air Defense and Air Traffic Control Radar and will provide comprehensive real time, 360 degree situational awareness.

Having successfully completed the demonstration phase, Northrop Grumman will deliver its final LTAMDS proposal to the Army in the coming weeks for evaluation.

U.S. Army’s LTAMDS program

The Lower Tier Air and Missile Defense Sensor (LTAMDS) program is a U.S. Army competition to procure a new air and missile defense radar.

The new system will replace the older Patriot air and missile defense radar system.

According to a request posted on the Federal Business Opportunities website by the Army on May 14, the service will use the data received from the ‘sense off’ event conducted at the White Sands Missile Range (WSMR) to help determine which company it will select to build six prototypes for FY 2022 fielding. A follow-on contract for 16 additional radars is also expected, according to the request.

The companies that participated in the ‘Sense Off’ event include Raytheon, Lockheed Martin partnering with Israeli radar company Elta Systems and Northrop Grumman.
