About this vehicle

The Department of the Navy Naval Facilities Engineering Command established the Undersea Weapons and Undersea Defensive (UW/UD) Family of Systems Multiple Award Contract on January 24, 2024, as an IDIQ covering design, development, fabrication, integration, testing, evaluation, documentation, and delivery of rapid prototype solutions for undersea weapons and undersea defensive systems, with ordering authority extending through January 23, 2029. The vehicle carries a shared ceiling of $245.9 million and has no set-aside restrictions.

The contract remains actively ordered. Since inception, 34 task orders have been awarded across 26 prime contractors, with combined potential value of $109.9 million against which $44 million (40%) has been obligated. Ordering intensity accelerated sharply in 2024 with 30 awards following 2 pilot orders in 2023; only 2 orders have been placed in 2026 as of late February. The two most recent awards (both in February 2026) focused on design studies for the MK 48 MOD 7 Guidance and Control Section with ceilings around $2 million each.

Task orders concentrate heavily on torpedo and undersea warfare platform engineering and software development. Representative awards include NIXIE torpedo defense system services ($33.5 million ceiling, obligated through December 2027), MK 48 and MK 54 engineering services ($17.8 million ceiling, obligated through September 2029), advanced processor build operational software development for torpedo variants ($19.1 million ceiling, obligated through May 2029), and undersea vehicle repair and upgrade work for IVER-3 unmanned underwater vehicles ($651 thousand firm fixed price).

Competition shows moderate concentration. Sonalysts Inc. and Science Applications International Corporation lead by order count and potential value, each holding 3 orders; combined they represent roughly 67% of the vehicle's total potential value at $73.8 million. RTX BBN Technologies, Mikel Inc., and Lockheed Martin Corporation round out significant players, with a long tail of smaller awardees. Customer concentration is extreme: Navy Sea Systems Command funds 32 of 34 orders (99.8% of potential value), leaving Naval Facilities Engineering Command with only a $20 thousand minimum guarantee pair.

All task orders are unrestricted competitive awards. Pricing is split between cost-plus-fixed-fee (dominant for engineering and development work with ceiling values typically 300–450% of initial obligation) and firm-fixed-price (used for smaller engineering studies and vehicle repair). Performance periods range from under one year for design studies to multi-year efforts extending through 2029.

Description
