The Department of the Navy is conducting market research for a potential Indefinite Delivery-Indefinite Quantity Multiple Award Contract (IDIQ-MAC) to support the Tech Insertion Acoustic-Rapid COTS Insertion (A-RCI) program, which delivers processing and display upgrades for submarine sonar systems. The contract would cover five functional areas: Cabinet Design and Production, Sensor Processing Software, Fleet Support, Certification Support Lab, and Logistics Support. The period of performance includes a five-year base period with an additional five-year ordering period option. No specific budget amount is mentioned. The location for performance is not specified, but fleet support may require on-site assistance at waterfront or underway locations.
