RTX's Lower Tier Air and Missile Defense Sensor showcases 360° protection in latest test

Raytheon, an RTX business, successfully completed another 360° flight test for the Lower Tier Air and Missile Defense Sensor, or LTAMDS, using one of the radar's secondary arrays to track and intercept a complex, threat representative target. This follows the radar's recent Milestone C designation, initiating the transition from prototype to production and deployment.

In this test, LTAMDS, supported an Integrated Battle Command System and a PAC-3 MSE missile intercept of a threat representative target. The test objective was to demonstrate LTAMDS' successful integration with the recently delivered Large Tactical Power Source (LTPS). The increased power provided by LTPS enables LTAMDS to reach its full battlespace potential.

The high capacity, full coverage provided by LTAMDS three radar arrays enable the defeat of massive, coordinated attacks that include a mix of threats such as drones, advanced aircraft, as well as ballistic, cruise and hypersonic missiles. LTAMDS has now completed nine successful flight tests of increasing complexity to prove its capabilities against real-world threats.

“LTAMDS' 360° full-sector sensing capabilities specifically address massive, coordinated attacks from adversaries,” says Tom Laliberty, president of Land & Air Defense Systems at Raytheon. “As international demand grows, Raytheon continues to invest in our production capacity to quickly deliver this critical capability to customers.”

In April 2025, the U.S. Army designated LTAMDS as an official program of record. In 2024 Poland became the first international customer to add LTAMDS to their air and missile defense architecture. Several more countries are actively planning to acquire LTAMDS to modernize their air defenses. The company is making significant capital investments to meet global demand.
