Lower Tier Air and Missile Defense Sensor (LTAMDS)


Lower Tier Air and Missile Defense Sensor (LTAMDS)  


GaN-based, 360-degree missile defense for the Army


What is LTAMDS?

The Lower Tier Air and Missile Defense Sensor (LTAMDS) is the U.S. Army's next generation of missile warning radar systems and a replacement for the legacy Patriot radar.

Designed from the outset to meet warfighters' current and future needs, Northrop Grumman's LTAMDS solution aligns with the Army's top requirements, including speed to field in order to outpace the threat.



Radar Technology

At the forefront of advanced radar systems Northrop Grumman's LTAMDS takes advantage of advanced, affordable, low-risk, in-production and fielded technologies from across our broad active electronically scanned array (AESA) portfolio. With systems in operation at sea, air, land and space, Northrop Grumman has been keeping warfighters safe since the advent of radar in World War II. And with growth potential built in, our LTAMDS radar is ready to grow into additional missions to protect our warfighters today and in the rapidly changing threat environment. We successfully demonstrated our capability to the Army at the recent Sense Off. Our LTAMDS offering builds upon Northrop Grumman's tradition and history of being a radar powerhouse.

GaN Semiconductor

As a semiconductor material, gallium nitride (GaN) offers efficiency and high power density, an ideal combination of attributes for radio frequency applications, including radars and electronic warfare systems. Northrop Grumman scientists and engineers are building upon the company's decades of expertise with GaN and other advanced materials to empower warfighters in their missions. They are also shaping the next generation of microelectronics.

One technology under development is Super Lattice Castellated Field Effect Transistor (SLCFET), the company’s patented structure that uses GaN to offer even greater levels of performance. To learn more about SLCFET and our experience with advanced materials, read Sensing the Future.
