Northrop Grumman [NOC] has submitted a proposal for the Army’s Lower Tier Air and Missile Defense Sensor (LTAMDS) program to find a replacement for the Patriot system’s radar, ahead of a prototype contract likely to be awarded this fall.

The announcement arrives after Northrop Grumman completed a demonstration of its radar offering for Army officials during a two-week “sense-off” event at White Sands Missile Range in New Mexico in May.

Northrop Grumman’s 360-degree coverage, GaN-based LTAMDs capability was successfully demonstrated to the U.S. Army during a two-week Sense Off at White Sands Missile Range, New Mexico

 “Our solution is ready today for tomorrow’s threats. It leverages significant government and industry investment in proven, fielded programs of record to deliver a 360 degree, full-sector GaN based sensor that is architected to meet the U.S. Army’s urgent requirements while enabling significant capability

growth for the future,” Christine Harbison, vice president of Northrop Grumman’s land and avionics C4ISR division, said in a statement. 

The LTAMDS program will look to replace the Patriot radar after Army officials determined incremental upgrades may not provide the necessary capability to handle future threats.

Raytheon [RTN], which builds Patriot and its current radar, announced Tuesday it had submitted its own bid for LTAMDS (Defense Daily, July 16). Lockheed Martin [LMT] is also slated to participate in the radar competition as well. 

Northrop Grumman has previously noted its LTAMDS offering also includes embedded logistics capability to enable improved sustainability of the radar over the course of the program (Defense Daily, June 4).
