Raytheon, an RTX business, is investing $100 million to expand its facility in Portsmouth, Rhode Island. The company said the expansion will accelerate Lower Tier Air and Missile Defense Sensor testing and increase Patriot GEM-T subcomponent production.

The investment is intended to increase testing capacity for LTAMDS and support growing global demand for Patriot GEM-T components. Raytheon said the Portsmouth expansion will help deliver air and missile defense capabilities to U.S. and international customers more quickly.

“This investment strengthens our ability to deliver critical air and missile defense capabilities to customers around the world,” said Tom Laliberty, president of Land & Air Defense Systems at Raytheon. “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.”



The announcement comes eight months after Raytheon broke ground on a $53 million expansion of its Radar Production Facility in Andover, Massachusetts. LTAMDS is a radar designed to defeat advanced threats, including hypersonic weapons.

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

The Patriot Advanced Capability-2 Guidance Enhanced Missile-Tactical, or GEM-T, is designed to intercept all types of airborne threats, including tactical ballistic missiles. It is a primary effector for the combat-proven Patriot air and missile defense system.



RTX businesses have operated in Rhode Island for more than 60 years. The company currently employs more than 850 people in the state.

Raytheon’s Portsmouth campus supports undersea technology, combat systems and radars. The new investment expands the site’s role in supporting radar testing and interceptor production for air and missile defense programs.
