The Naval Information Warfare Center Pacific is seeking proposals for worldwide Intelligence, Surveillance, and Reconnaissance systems support, with work potentially performed on afloat vessels, in port, or at sea alongside coalition partners. The requirement is for technical services including algorithm development, hardware and software work, systems engineering, and sustainment to develop and field advanced ISR capabilities. The procurement anticipates awarding multiple indefinite-delivery, indefinite-quantity contracts with a seven-year ordering period. The competition is full-and-open under NAICS code 541715 with a 1,000-employee size standard, and security classifications will range from Unclassified to Top Secret/SCI. This is a follow-on requirement from previous contracts.
