U.S. Awards Lockheed Martin $439M ATACMS Contract for Taiwan FMS

Contract Overview

The U.S. Army has awarded Lockheed Martin approximately $439 million to begin production of the Army Tactical Missile System (ATACMS), along with the launcher hardware required to fire it. The contract is funded through Taiwan's Foreign Military Sales (FMS) program.

Once both sides finalize the terms, the full agreement is expected to reach nearly $900 million. Work will be carried out at Lockheed Martin's facility in Grand Prairie, Texas, with an estimated completion date of February 2031.

About ATACMS

ATACMS is a surface-to-surface ballistic missile fired from the same HIMARS launcher trucks that have gained widespread recognition since Ukraine began using them to strike Russian ammunition depots and command posts deep behind front lines.

Key characteristics:

• Unlike the shorter-range guided rockets typically fired by HIMARS, ATACMS follows a ballistic trajectory, launching in a steep arc before descending on its target
• Range varies by version:
• Older variants: approximately 300 kilometers (186 miles)
• Newer M57 variants: approximately 500 kilometers (311 miles)

Contract Structure

The Pentagon structured this deal as an undefinitized contract action, a type of agreement that allows a contractor to begin manufacturing immediately while both sides continue negotiating the final, fully agreed-upon price. This approach is common when a customer requires rapid production rather than waiting months for every contract detail to be finalized.

Notably, the government solicited and received only one bid, underscoring that Lockheed Martin remains the sole domestic manufacturer capable of building ATACMS, leaving the Pentagon with no competitive alternative regardless of price.

Funding and Management

The Army obligated the initial payment using this year's Foreign Military Sales funds designated for Taiwan, meaning Taipei is financing this production run. The Army Contracting Command at Redstone Arsenal in Alabama is managing the contract on the government's behalf.

Background: December 2025 Arms Package

This contract stems from a much larger deal announced in December 2025, when the Trump administration approved the largest single U.S. weapons package Taiwan has ever received, valued at more than $11 billion. That package included:

• 420 M57 ATACMS missiles (some being the newer, longer-range variant)
• 82 additional HIMARS launcher systems
• More than 1,200 precision-guided rockets

This expands Taiwan's ATACMS arsenal more than fivefold compared to an earlier phase of the same long-range missile program, which included 29 HIMARS launchers and hundreds of precision-guided rockets. That earlier phase has already been substantially delivered, providing Taiwan with a working baseline capability.

Regional Context

The People's Liberation Army staged large-scale military exercises around Taiwan at the end of December. Chinese state broadcaster CCTV specifically highlighted Taiwan's HIMARS systems during the drill, with a soldier shown confirming target information on the launchers before simulating a strike sequence, according to a report reviewed by Taiwan's Central News Agency.

Military analysts told the agency that Beijing views the expanded HIMARS and ATACMS arsenal as a genuine threat, as the missiles could conduct deep counterstrikes against Chinese rocket forces and logistics hubs. One researcher at Taiwan's Institute for National Defense and Security Research noted that an ATACMS fired from Taiwan's outlying islands in the strait could threaten much of China's Fujian Province and reach a target in roughly the same seven minutes it would take a Chinese long-range rocket to strike Taiwan in return.
