The Department of Defense, specifically the Naval Undersea Warfare Center Division Newport (NUWCDIVNPT), intends to award a Cost Plus Fixed Fee (CPFF) Indefinite Quantity/Indefinite Delivery (ID/IQ) contract for the sustainment of the Submerged Acoustic Navigation System (SANS) to Mikel, Inc. This procurement involves engineering services and hardware related to Submarine Acoustic Navigation Systems, with a total of approximately 196,800 man-hours anticipated over a five-year period. The contract is a follow-on to a previous award and is being pursued on a Sole Source basis due to Mikel, Inc.'s ownership of the relevant data developed under prior Small Business Innovation Research (SBIR) efforts. Interested parties may submit capability statements for consideration, with the Request for Proposal (RFP) expected to be released around September 2024.
