RTX subsidiary wins $1B Army contract

The U.S. Army has awarded Raytheon, a subsidiary of Arlington County Fortune 500 aerospace and defense contractor RTX, a $1.025 billion contract modification to support production of the Lower Tier Air and Missile Defense Sensor (LTAMDS).

According to RTX, the sensor is a radar tool designed to defeat advanced and next-generation threats such as hypersonic weapons. It has three antenna arrays that work together to detect and engage multiple threats from any direction at the same time.

The Department of Defense on Thursday announced the contract would support year two production. Work would be performed in Andover, Massachusetts, with an estimated completion date of March 31, 2030. The Army Contracting Command, based in Redstone Arsenal, Alabama, paid $254.57 million of the $1.025 billion total at the time of the award.

The latest contract modification builds upon a $2.09 billion contract Raytheon was awarded by the Army in July 2024 for low-rate initial production of the sensor, as well as a $1.7 billion award in August 2025.

RTX has more than 185,000 employees globally and reported more than $80.73 billion in 2024 sales. The contractor is the second-highest-ranked Virginia-based company on the 2025 Fortune 500. RTX’s Raytheon business unit is also based in Arlington.
