RTX Puts $100 Million Into Portsmouth Expansion to Speed Radar Testing and Interceptor Output

Overview

• RTX announced on Monday, June 8, 2026 that Raytheon will invest $100 million to expand its Portsmouth, Rhode Island facility and that the project is expected to create about 150 skilled jobs.
• The work will increase capacity for testing the Lower Tier Air and Missile Defense Sensor (LTAMDS) and boost production of Patriot GEM‑T subcomponents to shorten delivery times for customers.
• Raytheon is under contract to supply LTAMDS radars to the U.S. Army and Poland and the program recently completed a ninth flight test in which the radar tracked and supported an intercept of a surrogate target.
• The Army’s fiscal year 2027 budget request includes roughly $2 billion to buy 12 low‑rate initial production LTAMDS sensors with plans for another 38 sensors through FY‑31, a procurement timeline that drives the industrial ramp.
• The Portsmouth expansion follows a prior $53 million upgrade in Andover, Massachusetts, and responds to sustained allied demand and stockpile replenishment pressures that have strained Patriot and radar supply lines.
