MOORESTOWN, N.J., — May 9, 2026 : The U.S. Missile Defense Agency (MDA) has awarded Lockheed Martin a $407.16 million contract modification to continue engineering, integration, development, and certification work for the Aegis Guam System, a major component of the U.S. military’s expanding missile defense network in the Indo-Pacific region.
The modification, awarded on May 7 on a sole-source basis, increases the cumulative value of the underlying Aegis Ballistic Missile Defense (BMD) Weapon Systems contract from approximately $1.528 billion to more than $1.935 billion. The work is scheduled to continue through December 2029.
According to the Department of War, the contract is structured as a hybrid cost-plus-fixed-fee and cost-plus-incentive-fee arrangement, a format commonly used for complex defense development programs involving evolving technical requirements. The structure allows the government and contractor to share development risks while providing financial incentives tied to schedule and performance targets.
Initial Funding and Contract Structure
At the time of the award, the government obligated $78.7 million in immediate funding under the modification. The obligated amount includes $76.16 million in fiscal year 2026 research, development, test, and evaluation (RDT&E) funds and $2.6 million in fiscal year 2026 procurement funds. Remaining funding is expected to be distributed incrementally over the duration of the program.
The contract modification, identified as P00151 under contract HQ0851-21-C-0002, will support ongoing software integration, systems engineering, testing, and certification activities required for the Guam missile defense architecture.
Lockheed Martin will perform the majority of the work at its Moorestown, New Jersey, facility, while additional integration and testing operations will take place in Guam. The Missile Defense Agency office in Dahlgren, Virginia, is serving as the contracting authority managing the effort.
Integrated Missile Defense Architecture
The Aegis Guam System is part of the military’s broader Enhanced Integrated Air and Missile Defense (EIAMD) initiative designed to establish a persistent, layered, and 360-degree defense capability for Guam.
The program adapts the Aegis combat system architecture, widely used aboard U.S. Navy destroyers and cruisers, into a fixed land-based configuration tailored specifically for Guam’s operational environment. Rather than functioning as a standalone interceptor platform, the system is being developed as a distributed battle-management architecture linking Navy, Army, and joint-service sensors and weapons into a unified network.
The Guam defense system is expected to integrate with the U.S. Army’s Integrated Battle Command System (IBCS), enabling coordinated engagements using multiple interceptor systems, including Standard Missile-3 (SM-3), Standard Missile-6 (SM-6), Terminal High Altitude Area Defense (THAAD), and Patriot Advanced Capability-3 (PAC-3).
For detection and tracking, the system will utilize the TPY-6 radar, a ground-based variant of Lockheed Martin’s AN/SPY-7(V)1 solid-state radar technology designed to track ballistic, cruise, and advanced maneuvering missile threats.
Strategic Importance of Guam
Guam remains one of the most strategically important U.S. military locations in the Indo-Pacific region. The island hosts Andersen Air Force Base and Naval Base Guam, both of which support logistics, command-and-control operations, and force projection activities across the Pacific theater.
The territory lies within range of ballistic, cruise, and hypersonic missile systems operated by China and North Korea, increasing the urgency of establishing a permanent and integrated missile defense network for the island.
Defense planners view the Aegis combat system as a proven operational foundation because of its long record of intercepting short-, medium-, and intermediate-range ballistic missile threats. The ongoing work under the latest contract modification will focus on adapting those capabilities to Guam’s fixed-site defense requirements and validating system performance against regional threat scenarios.
Long-Term Development Effort
Lockheed Martin continues to serve as the Combat System Engineering Agent for Aegis programs, supporting software development, testing, certification, integration, and sustainment activities across the missile defense enterprise.
The broader Guam Defense System is intended to provide continuous protection for critical military infrastructure on the island, including airfields, naval facilities, logistics hubs, and command-and-control assets as the United States expands its regional defense posture in the Indo-Pacific.
