The Department of Defense, through the Naval Air Warfare Center Training Systems Division (NAWCTSD), is seeking to increase the contract ceiling for the Fielded Training Systems Support (FTSS V) Indefinite Delivery/Indefinite Quantity (ID/IQ) contract on a sole-source basis. This increase, estimated at approximately $720 million, aims to ensure the continued provision of Contractor Operation and Maintenance Services (COMS) and Contractor Instructional Services (CIS) for the U.S. Navy and Marine Corps' training systems, which support over twenty-four weapons platforms across various military sites. The sole-source justification is based on the limited number of suppliers capable of meeting the agency's needs, and responses from interested parties, particularly those holding the current FTSS MAC, are solicited regarding their capabilities to provide these services. Interested parties must submit their responses by June 17, 2025, and can contact Reagan Gill at reagan.gill@navy.mil or Jana McEntegart at jana.mcentegart@navy.mil for further information.
