Lockheed Martin wins $948m in US Navy contract modifications for F-35 sustainment and Trident II design work

# What happened Lockheed Martin received two US Navy contract modifications totalling nearly $948 million. One modification enlarges the long-running F-35 sustainment contract to cover equipment and non-recurring sustainment work for activating and supporting F-35 operational sites. The other funds continued advanced design and development effort for the Trident II (D5) Life Extension 2 programme.

# F-35 sustainment modification The larger award is an $871.2 million change to an existing cost-plus-incentive-fee, indefinite-delivery/indefinite-quantity contract for the F-35 Lightning II programme. The modification raises the contract ceiling so the Navy can buy additional sustainment equipment and perform related hardware non-recurring sustainment tasks needed to activate and maintain F-35 deployment sites both ashore and at sea.

• Customers cited include the US Marine Corps, US Navy, US Air Force, international partners, and countries buying the jet through Foreign Military Sales.

• Completion is scheduled for February 2031.

• River, Maryland, is managing the contract.

# Trident II (D5) Life Extension modification Lockheed Martin Space received a $76.6 million cost-plus-incentive-fee modification tied to the Trident II (D5) Life Extension 2 advanced design and development effort. The modification supports continued design work for the submarine-launched ballistic missile's life-extension activities.

• Work will be performed at multiple locations, primarily in Denver, Colorado.
• The work has a completion date of 30 September 2030.

• The effort was awarded sole-source after appearing on the government contracting portal with only one proposal received.
• Strategic Systems Programs in Washington, DC, is overseeing the contract.

# Context and recent activity The announcement follows other recent Lockheed Martin contract actions reported by the same source, including contract modifications exceeding $1 billion for MK 48 heavyweight torpedoes and various standoff missile systems. That earlier set of modifications expanded production and support activities for torpedoes and missile programs.

# What this means for operators and supply chains The F-35 modification funds the unglamorous but essential work that lets a base or ship actually operate the jet: supplies, specialized tools, sustainment hardware, and site activation services. The Trident II award continues design work intended to keep the D5 missile in service through the next decades, with design work concentrated at facilities that support missile and space systems.

# Bottom line The pair of modifications consolidates Lockheed Martin's role in two different lifecycle phases: near-term fielding and sustainment of the F-35 fleet and longer-term design work on the Trident II life-extension programme. Each award uses different funding mechanisms and oversight organisations and assigns work to distinct geographic hubs.
