Lockheed Martin Gets $76.6M Trident II D5LE2 Contract

Lockheed Martin Gets $76.6M Trident II D5LE2 Contract

Lockheed Martin Space has received a $76.6 million contract modification from the U.S. Navy for advanced design and development work supporting the Trident II D5 Life Extension 2 (D5LE2) program.

According to the U.S. Navy’s Strategic Systems Programs (SSP), the $76,562,774 cost-plus-incentive-fee modification, designated P00032, was awarded against contract N0003024C0100. The work supports the D5LE2 SSP Alteration (SPALT) Advanced Design and Development Program and is scheduled to run through Sept. 30, 2030.

Scope of the Trident II D5LE2 Lockheed Martin Contract

The modification covers advanced design and development activities associated with the D5LE2 program. The Navy’s announcement identifies the work as part of the SSP Alteration effort, but does not disclose specific engineering tasks, hardware quantities, component changes, or individual subsystem performance targets.

The announcement also does not disclose a production quantity or identify a separate delivery schedule for completed D5LE2 hardware under this modification.

D5LE2 is part of the broader effort to extend and modernize the Trident II D5 strategic missile system. Lockheed Martin has been the prime contractor responsible for the Trident II D5 missile and associated modernization activities.

Trident II D5 Technical and Operational Context

The Trident II D5 is a submarine-launched ballistic missile that forms a central component of the U.S. Navy’s sea-based strategic deterrent. It is deployed aboard Ohio-class ballistic missile submarines and is also associated with the future Columbia-class strategic submarine force.

The D5 Life Extension 2 effort is intended to support the continued service of the strategic missile system as the Navy transitions from the Ohio-class to the Columbia-class. Modernization work on a long-serving strategic weapon can involve engineering changes intended to sustain system reliability, compatibility, manufacturing capability, and long-term support.

The contract announcement does not specify which D5 missile components or subsystems will be altered under this particular advanced design and development action. Those details should therefore not be inferred from the award value or contract title.

Operational Impact on U.S. Navy Strategic Deterrence

The award supports the Navy’s long-term management of its sea-based strategic weapons capability.

The Trident II D5 system is designed for deployment from ballistic missile submarines, giving the Navy a survivable component of the U.S. nuclear triad. Maintaining the missile through life-extension and modernization programs allows the Navy to continue supporting the system while its strategic submarine fleet undergoes a generational transition.

The current contract is a development action rather than an announcement of a new missile production quantity. Its significance is therefore tied to engineering and modernization work supporting the longer-term D5LE2 program.

Contract Breakdown: Lockheed Martin Space Award Details

Contract Value

The Navy awarded $76,562,774 under modification P00032. The entire amount is being obligated from fiscal 2026 weapons procurement, Navy, funds.

The announcement states that none of the obligated funds will expire at the end of the current fiscal year.

Contractor

Lockheed Martin Space, based in Titusville, Florida, is the contractor receiving the modification.

Contract Type

The action is a Cost-Plus-Incentive-Fee modification to previously awarded contract N0003024C0100.

The contract was awarded on a sole-source basis under 10 U.S. Code 2304(a)(1). The Navy states that the requirement was previously synopsized on the Systems for Award Management website and that one proposal was received.

Work Locations

Denver, Colorado, accounts for 51% of the work, making it the largest location under the modification.

Other identified locations include:

Performance Period

Work is expected to be completed by Sept. 30, 2030.

Funding

Fiscal 2026 Navy weapons procurement funds totaling $76,562,774 will be obligated under the modification. The announcement states that no funds will expire at the end of the current fiscal year.

Options or Follow-On Work

The announcement does not identify options or a separate follow-on award associated with this modification.

Lockheed Martin Defense Industrial Base and Acquisition Impact

The modification distributes work across a broad U.S. industrial network supporting the D5LE2 effort. More than half of the identified work is allocated to Denver, while additional engineering, manufacturing, and support activity is spread across multiple states.

From an acquisition perspective, the use of a cost-plus-incentive-fee modification reflects an effort centered on advanced design and development rather than a straightforward fixed-price production purchase. The incentive-fee structure can be used for development work where technical requirements and execution risks require continued contractor effort and government oversight.

The sole-source structure also reflects the specialized nature of the work identified in the announcement. The Navy states that the requirement was previously synopsized and that one proposal was received.

Trident II D5LE2 Program Milestones and Next Steps

The immediate milestone established by the award is continued advanced design and development work through Sept. 30, 2030.

The announcement provides no additional public schedule for specific D5LE2 design reviews, testing events, hardware deliveries, or production decisions. Those milestones may be established through subsequent program actions, but they should not be treated as confirmed until disclosed by the Navy or another authoritative source.

Strategic Systems Programs in Washington, D.C., is the contracting activity responsible for the award.
