PORTSMOUTH, R.I. — Raytheon is investing $100 million to expand its Portsmouth facility, a project expected to bring 150 high-tech jobs to Rhode Island. The buildout is intended to accelerate testing of the Lower Tier Air and Missile Defense Sensor (LTAMDS) by increasing capacity and to boost Patriot GEM-T subcomponent production to meet growing global demand.
“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 move comes eight months after the company broke ground on a $53 million expansion of its Radar Production Facility in Andover, Massachusetts. LTAMDS is a radar designed to counter advanced threats, including hypersonic weapons.
Raytheon is under contract to deliver multiple LTAMDS radars for 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 (PAC-2) Guidance Enhanced Missile-Tactical (GEM-T), designed to intercept a range of airborne threats including tactical ballistic missiles, serves as a primary effector for the Patriot air and missile defense system.
RTX businesses have operated in Rhode Island for more than 60 years and employ more than 850 people. The Portsmouth campus supports undersea technology, combat systems and radars.
