About this opportunity
The Naval Information Warfare Center (NIWC) Pacific is soliciting proposals under RFP No. N6600126R0018 for Unmanned Maritime Systems Support (UMSS), a comprehensive suite of engineering services encompassing specification, design, fabrication, development, integration, assembly, installation, testing, evaluation, fielding, operations, maintenance, training, logistics, and program management for unmanned maritime systems supporting U.S. Navy missions. The procurement covers both current systems and future waterborne and underwater technologies across multiple mission areas including explosive ordnance disposal (EOD), mine countermeasures (MCM), force protection (FP), intelligence/surveillance/reconnaissance (ISR), mine warfare (MIW), anti-submarine warfare (ASW), and specialized undersea and surface applications. The solicitation is classified under NAICS Code 541330 (Engineering Services) with a small business size standard of $47 million and is open to full-and-open competition with no set-asides. The proposal due date is December 11, 2025, at 15:00 Pacific Time, as extended by Amendment 0001, and multiple amendments have been issued including clarifications and a DD Form 254 (Department of Defense Security Agreement). The work will involve varying security classifications ranging from Unclassified to Top Secret/Sensitive Compartmented Information (TS/SCI) levels.
The procurement will result in multiple indefinite-delivery, indefinite-quantity (IDIQ) contracts using cost-plus-fixed-fee (CPFF) and cost (no fee) pricing arrangements over an eight-year ordering period, with orders placed pursuant to FAR 16.505(a) procedures. This is a follow-on requirement to existing contracts N6600121D0132 through 0140, indicating incumbent contractors may be eligible for continuation awards. While specific contract values are not disclosed in the solicitation, the eight-year performance period and multiple IDIQ contract structure suggest substantial long-term funding potential. The work will be performed under contract with NIWC Pacific, supporting Navy operations globally. Prospective contractors must be capable of handling classified work, possess relevant unmanned systems engineering expertise, and demonstrate proficiency in complex system integration and lifecycle management across diverse maritime applications.
