The Department of Defense, specifically the Army Contracting Command at Redstone Arsenal, is seeking to acquire a fifth battery for the Mid Range Capability (MRC) weapon system through a sole-source contract with Lockheed Martin Corporation (LMC). This procurement is necessitated by the Army's immediate need for additional Ground Support Equipment (GSE) and is justified under Title 10 U.S.C. 3204(a)(1), as LMC is the only responsible source capable of fulfilling the requirements due to their prior development and production of the first four batteries. The MRC system is critical for enhancing the Army's operational capabilities, and the decision to proceed without full and open competition is based on the lack of comprehensive technical data packages and the significant costs and delays associated with transitioning to another vendor.
