This is a Justification and Approval (J&A) document for use of other than full and open competition for a contract modification awarded to General Dynamics Mission Systems (GDMS) by the Naval Surface Warfare Center, Port Hueneme Division (NSWC PHD).

The modification increases the ceiling on Contract No. N63394-24-C-0004 to add funding to Option Year Two, extending the period of performance through March 31, 2027. The contract provides in-service engineering and lifecycle support for Command, Control, Communications, Computers, Combat Systems and Intelligence (C5I) system elements of the Littoral Combat Ship (LCS) combat systems equipment specific to the Independence (Indy) variant. Services include C5I system critical engineering, design, integration, test and evaluation, software development and testing, system upgrade and replacement planning, logistics product development and distribution, and training systems. The government determined GDMS is the only responsible source capable of meeting requirements because it serves as the platform In-Service Engineering Agent (ISEA) for much of the Navy's LCS combat systems equipment, is the Original Equipment Manufacturer (OEM) of the Indy variant combat system, possesses proprietary data rights and subject matter expertise, maintains established infrastructure, and operates Design Integration Facilities uniquely qualified to support all LCS Indy variant hull baselines. Contract authority is based on 10 U.S.C. 3204(a)(1), as only one responsible source can satisfy agency requirements. Market research was conducted via a sources sought notice on SAM.gov posted October 21, 2025, with ten companies expressing interest. The contracting officer has determined the anticipated cost to the government is fair and reasonable.
