Raytheon Completes First LTAMDS Radar Antenna

Raytheon finished building the first radar antenna array for the U.S. Army’s Lower Tier Air and Missile Defense Sensor (LTAMDS), the company announced.

Raytheon completed the work less than 120 days after the U.S. Army selected Raytheon to build LTAMDS, a next-generation radar that will defeat advanced threats like hypersonic weapons.

LTAMDS is a new radar that will ultimately replace the current U.S. Army Patriot radars and will operate on the Army’s Integrated Air and Missile Defense (IAMD) network.

“Raytheon’s employees and partners are focused on delivering the first LTAMDS by the Army’s Urgent Material Release date because we know how important expanded battlespace coverage and other capabilities are to the men and women in uniform,” said Tom Laliberty, vice president of Integrated Air and Missile Defense at Raytheon’s Integrated Defense Systems business. “Because we invested in cutting-edge radar technology and advanced manufacturing capability, we will meet the customer’s critical milestones and get LTAMDS in the field rapidly.”

Raytheon’s LTAMDS solution is a 360-degree, Active Electronically Scanned Array (AESA) radar powered by company-manufactured Gallium Nitride (GaN), a substance that strengthens the radar signal and enhances its sensitivity. Over the past two decades, Raytheon has invested significantly in AESA GaN technology and advanced manufacturing capability, positioning the company as the global leader in advanced GaN technology and product development.

The newly built primary array, similar in size to the Patriot radar array, will provide more than twice its performance. Following extensive testing, the radar array will be mounted on a precision-machined enclosure for integration and further evaluation. The enclosure utilizes advanced design and manufacturing techniques for accelerated manufacture to support the U.S. Army’s Urgent Materiel Release program.

Raytheon is working closely with hundreds of suppliers across 42 states, including a core team playing a strategic role in building the LTAMDS solution. They are:

• Crane Aerospace & Electronics
• Cummings Aerospace
• IERUS Technologies
• Kord Technologies
• Mercury Systems
• nLogic
