Peraton Wins $17.3M MK 18 EOD UUV Sustainment Contract

Technical Summary

Naval Information Warfare Center Pacific (NIWC Pacific) awarded Peraton a cost-reimbursement contract on 4 May 2026 with a base value of $17.3 million covering one year of performance from 4 May 2026 through 3 May 2027. Four one-year options would lift the ceiling to $90.6 million and extend coverage to May 2031. The award sustains the MK 18 family of unmanned underwater vehicles (UUVs) — the United States Navy’s primary man-portable autonomous platform for very-shallow-water and shallow-water mine countermeasures (MCM) and explosive ordnance disposal (EOD) reconnaissance.

The MK 18 family comprises two variants. MK 18 Mod 1 (Swordfish) is built on the Hydroid REMUS 100 and operates from small craft and rigid hull inflatable boats. MK 18 Mod 2 (Kingfish) is the larger REMUS 600 variant, with longer endurance, deeper diving capacity and the side-scan and synthetic aperture sonar payloads required to localise bottom and moored mines in the very-shallow-water (VSW) and shallow-water (SW) zones. Both are operated by Navy EOD Mobile Units and underpin the post-Avenger MCM concept of operations.

Analysis of Effects

The contract is sustainment, not new procurement. Peraton will perform field engineering, repair, modification, training and forward logistics support across the geographical hubs that hold MK 18 vehicles in operational rotation: San Diego (NIWC Pacific home), Joint Expeditionary Base Little Creek (Virginia), Naval Station Rota (Spain), Naval Support Activity Bahrain, and Okinawa. The presence of forward sustainment in Rota and Bahrain matters operationally — it indicates a continued requirement to keep the platform mission-ready in the Black Sea approaches via Rota and the Strait of Hormuz via Bahrain, both areas where the Navy has reported elevated mine and improvised waterborne explosive risk.

From a Weapons Technical Intelligence (WTI) perspective, the MK 18 is a sensor platform — it does not neutralise ordnance directly. Once a target is localised, the EOD diver or a separate MK 18 Mod 2 with neutralisation payload (or a follow-on system such as the Barracuda one-shot mine neutraliser) prosecutes. The sustainment contract therefore preserves the front end of the MCM/EOD kill chain rather than the kinetic end.

Personnel and Safety Considerations

For Navy EOD/MCM personnel, the contract gives a four-year planning horizon for parts availability, maintenance training and surge support. The single-source posture (Peraton inherited the legacy support footprint from a chain of acquisitions through Harris IT Services and L3) means readiness for the platform is now dependent on one industrial pipeline; any disruption propagates to all five hubs simultaneously.

Safety considerations remain those of the underlying platform: lithium-polymer battery handling, in-water recovery in contested or current-affected littorals, and the standard EOD discipline of treating any sonar contact as live ordnance until physically inspected. The contract does not change the operational risk envelope — it preserves it.

Data Gaps

DATA GAP: the public award notice does not disclose the breakdown between Mod 1 and Mod 2 sustainment hours, the number of vehicles in the supported fleet, or the proportion of funding allocated to forward versus depot maintenance. The notice also does not state whether the contract scope includes integration of the upgraded REMUS 300 or the planned MK 18 Mod 3 successor; Defense Daily reported the Mod 2 production line closed in 2024, but sustainment of fielded vehicles is independent of new-build production. The export-control posture for forward-deployed spares in Rota, Bahrain and Okinawa is also not stated in open source.
