RTX Unit Raytheon’s $100M Investment Gets Investors Talking – Why Is LTAMDS Radar In The Spotlight Today?

• Raytheon is under contract to provide multiple LTAMDS radars to the U.S. Army and Poland.
• Raytheon noted that the investment comes just eight months after the company broke ground on a $53 million expansion of its LTAMDS radar production facility in Andover, Massachusetts.
• In September 2025, the U.S. Army awarded RTX a $1.7 billion contract to provide LTAMDS systems, making Poland the first international customer.

Shares of RTX Corp (RTX) drew investor attention on Monday after the defense giant announced that its unit, Raytheon, would invest $100 million in its Portsmouth facility.

Raytheon stated that it would accelerate testing of the Lower Tier Air and Missile Defense Sensor (LTAMDS) by increasing capacity and boosting Patriot GEM-T subcomponent production to meet growing global demand.

RTX’s LTAMDS Radar

The LTAMDS radar is designed to defeat advanced threats, including hypersonic weapons,  a growing priority for U.S. and allied defense planners.

Raytheon is under contract to provide multiple LTAMDS radars to the U.S. Army and Poland, and the program recently completed its ninth successful flight test, using the radar's multiple arrays to track and intercept a surrogate target, the company added.

"Expanding in Portsmouth allows us to scale production, advance LTAMDS testing, and ensure the U.S. Army and our international partners receive these systems as quickly as possible," said Tom Laliberty, president of Land & Air Defense Systems at Raytheon.

Raytheon noted that the investment comes just eight months after the company broke ground on a $53 million expansion of its LTAMDS radar production facility in Andover, Massachusetts.

Boost In Patriot Subcomponent Production

The expansion also boosts production of Patriot Advanced Capability-2 (PAC-2) Guidance Enhanced Missile-Tactical (GEM-T) subcomponents, a core component of the combat-proven Patriot air and missile defense system.

The GEM-T is designed to intercept all types of airborne threats, including tactical ballistic missiles, and has been deployed by U.S. forces and allies worldwide.

Patriot missile systems have been in huge demand since Russia’s invasion of Ukraine in 2022 and have also been used during the Middle East conflict, driving sustained order flow for RTX and Lockheed Martin.

During the first quarter, Raytheon reported sales of $6.9 billion, up 10% from the year-ago period. The sales were primarily driven by higher volume in land and air defense systems, including Patriot and GEM-T, and in naval munitions programs, the company noted.

In September 2025, the U.S. Army awarded RTX a $1.7 billion contract to provide LTAMDS systems, making Poland the first international customer to obtain these radar systems.
