The U.S. Navy intends to award a sole-source contract to Lockheed Martin in Titusville, Florida, for specialized engineering and technical services supporting the Trident II (D5LE) missile system and the Common Missile Compartment for the COLUMBIA class submarine. The contract will be a Cost-Plus Fixed Fee, Level-of-Effort arrangement, with performance expected from March 1, 2027, through February 28, 2032. Lockheed is considered the only viable source due to its unique expertise, methodology, and history with the TRIDENT program, as extensive training would be required for any other contractor. This notice is not a request for competitive proposals, but responses will be considered within 15 days of publication. A security clearance is required for this effort.
