The Department of Defense, specifically the Army Contracting Command - Detroit Arsenal (ACC-DTA), is seeking to procure Systems Technical Support (STS) services for the Maneuver Support Vessel Light (MSV(L)) program through a sole-source Request for Proposal (RFP) issued to Vigor Works, LLC. This procurement is justified under FAR 6.302-1(a)(2)(iii)(B) due to Vigor's status as the Original Equipment Manufacturer (OEM) and the only responsible source capable of meeting the Government's requirements, given the lack of available technical data for competitive re-procurement. The contract will be structured as a five-year Indefinite Delivery Indefinite Quantity (IDIQ), Cost-Plus-Fixed-Fee (CPFF) contract, with an estimated total of 380,493 hours to be procured over its duration. Proposals are due by April 21, 2025, and interested parties can contact Charlene West at charlene.d.west.civ@army.mil for further information.
