Northrop Grumman Corp. has landed framework contracts from the Pentagon to provide parts for interceptor missiles made by Lockheed Martin Corp. The two systems involved are the Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3 MSE) and the Terminal High Altitude Area Defense (THAAD) interceptor.
The larger portion, valued at about $2 billion, is linked to the PAC-3 MSE. Northrop will manufacture solid rocket motors for that interceptor and also keep making ignition safety devices for the program. L3Harris Technologies Inc. is currently the only supplier of the rocket motor, so Northrop's entry creates a second source for that critical part. The PAC-3 MSE work accounts for most of that amount, according to Ben Davies, who leads Northrop's defense systems unit.
A separate arrangement valued at roughly $1 billion will aid Lockheed's THAAD production. Northrop will expand its current role producing high-temperature structural components for THAAD. The Defense Department wants to quadruple output of that interceptor, and the new agreement is designed to help meet that target.

These pacts fit into a larger effort to replace U.S. munitions inventories that have been strained over the last several years. Weapons sent to Ukraine, interceptors fired during Middle East operations, and munitions consumed in the conflict with Iran all contributed to the drawdown. The Trump administration has pressed major defense contractors to rebuild those stocks quickly.
Pentagon framework agreements of this type serve as preliminary commitments before a final contract is signed. Similar pacts have been reached in recent months with several arms makers, including Lockheed and Northrop. The broader initiative is intended to improve the availability of key munitions if a protracted war with China ever became necessary.
Northrop had been preparing for this moment for years. The company began investing $2 billion in its missile business in 2019, expanding operations in Utah, West Virginia, and Maryland because executives expected stronger demand for missile propulsion. Those facilities are now positioned to support the added PAC-3 and THAAD work.
Lockheed aims to triple PAC-3 production to 2,000 missiles per year by 2030. To support that goal, Northrop plans to ramp up solid rocket motor output over a two-to-three-year stretch at its West Virginia plant. The company is expanding that plant to triple its manufacturing capacity, Davies said.
In the near term, Northrop expects Lockheed to issue a production contract once the new framework deal is in place. The agreements come after Northrop invested $2 billion in its missile business beginning in 2019. That investment paid for expanded operations in Utah, West Virginia, and Maryland because company leaders expected stronger demand for missile propulsion systems.
The new pacts join a wider Pentagon push to restore American missile inventories that have been drained by repeated overseas shipments and steady interceptor use. That focus reflects both current conflicts and the need to be ready for a major-power confrontation. As production lines accelerate, companies like Northrop, Lockheed, and L3Harris will be central to the Pentagon's plan to avoid another inventory crisis.
