The U.S. Navy wants its next-generation maritime helicopter to carry a single sonar system capable of hunting both enemy submarines and sea mines, according to a cluster of federal procurement notices posted in early 2026 on the government’s SAM.gov contracting portal. The solicitations, tied to the service’s Future Vertical Lift (Maritime Strike) program, mark the clearest public signal yet that the Navy intends to merge two missions that have historically required separate aircraft, separate crews, and separate sensor suites.
If the effort succeeds, it could allow a carrier strike group to swap today’s patchwork of specialized airframes for a smaller fleet of multi-role helicopters, freeing precious flight-deck space and cutting response times in the shallow, mine-strewn coastal waters where a future Pacific conflict would most likely be fought.
Three solicitations, one program thread
Three distinct notices on SAM.gov form the public foundation of the effort. Each names the Navy’s Future Vertical Lift program and its Maritime Strike track, and each references a milestone known as Gate 2 R3B, a formal acquisition checkpoint that, in the Defense Department’s framework, typically signals a shift from early concept work into focused technology development.
The first solicitation centers on acoustic detection technology for a rotary-wing platform, confirming that airborne sonar is a core requirement for whatever helicopter emerges from the program. A second notice carries different contract identifiers but repeats the same program labels and milestone language, reinforcing that the sonar work is part of a coordinated acquisition push rather than an isolated research project. A third posting rounds out the set, again naming Future Vertical Lift (Maritime Strike) and Gate 2 R3B.
Whether the three notices represent competing approaches to a single sensor, separate components of an integrated system, or phased stages of one development effort is not spelled out in the publicly available summaries. Contractors will need to request the full solicitation packages to untangle the relationship.
Why the Navy wants a dual-mission sonar
Today, the Navy’s primary airborne submarine hunter is the Sikorsky MH-60R Seahawk, which carries Raytheon’s AN/AQS-22 Airborne Low Frequency Sonar, a dipping system optimized for tracking submarines in deep and littoral waters. Mine countermeasures, meanwhile, have been in flux since the retirement of the aging MH-53E Sea Dragon fleet. Much of that mission has shifted to surface ships, unmanned underwater vehicles, and the Airborne Mine Neutralization System carried by MH-60S helicopters.
Splitting the two jobs across different platforms works in peacetime, but it creates headaches in a contested environment. A carrier strike group approaching a strait laced with mines and patrolled by diesel-electric submarines would need to cycle different helicopters on and off the flight deck, each with its own maintenance tail and crew qualifications. A single airframe carrying a sonar suite that can switch between submarine tracking and mine detection would compress that timeline and reduce the logistical burden on the ship.
The operational pressure is real. The Pentagon’s 2024 China Military Power Report assessed that the People’s Liberation Army Navy operates roughly 60 submarines, a fleet Beijing continues to modernize with quieter conventional boats and new nuclear-powered attack submarines. China has also invested heavily in sea-mine inventories designed to deny access to chokepoints like the Taiwan Strait and the South China Sea’s island chains. Against that backdrop, the Navy’s push to combine anti-submarine warfare and mine countermeasures on one helicopter is less a technological curiosity than a strategic hedge.
Where Future Vertical Lift fits
Future Vertical Lift is the Pentagon’s umbrella effort to replace aging rotorcraft across all service branches. The Army’s portion, the Future Long-Range Assault Aircraft (FLRAA) competition, selected the Bell V-280 Valor tiltrotor in 2022. The Navy’s Maritime Strike track is a separate line of development, but it draws on the same family of advanced rotor and propulsion technologies. The SAM.gov notices do not name a specific airframe, and the Navy has not publicly committed to a tiltrotor, compound helicopter, or conventional rotor design for the Maritime Strike mission.
What the solicitations do make clear is that the service wants the sonar system and the aircraft to be developed in tandem. Weight, power, and cooling constraints on a helicopter directly shape what kind of acoustic array it can carry, how long it can hover while dipping, and how far it can fly between search stations. By issuing sonar-related solicitations at this stage of the acquisition process, the Navy is signaling that sensor integration will be baked into the aircraft’s design from the start rather than bolted on after the airframe is finalized.
What is still unclear
Several gaps remain in the public record. The SAM.gov summaries do not include performance specifications such as detection ranges, operating depths, or frequency bands. No dollar figures appear in any of the three postings, making it impossible to gauge whether the Navy envisions a rapid, well-funded prototype sprint or a slower, exploratory research phase spread across multiple budget cycles.
The Gate 2 R3B milestone itself carries a caveat. The reference appears in the citation trail linking the three solicitations, but a standalone announcement from the program executive office or a Defense Acquisition Board decision memo has not surfaced in publicly available records as of May 2026. The milestone should be treated as reported in procurement documents, not yet independently confirmed by named officials.
There is also an open question about sensor architecture. The notices do not specify whether the Navy wants a single multifunction transducer, a modular payload bay that can swap sonar heads between sorties, or a networked approach that fuses helicopter-mounted acoustics with sonobuoys and unmanned undersea vehicles. Each option carries different trade-offs in weight, complexity, and mission flexibility, and the choice will shape the aircraft’s design envelope for decades.
What contractors and fleet planners should watch for next
For defense contractors, the immediate step is straightforward: pull the full solicitation documents from SAM.gov and determine whether their capabilities in dipping sonar, towed arrays, mine-detection acoustics, or signal processing align with what the Navy is asking for. Companies should also press for clarity on how the three postings relate to one another before committing engineering resources to a proposal.
For the broader fleet, the stakes are larger. If the Navy can field a maritime helicopter that reliably detects both submarines and mines, it will have closed a gap that adversaries are actively trying to exploit. Carrier strike groups operating in the western Pacific, the Persian Gulf, or the Baltic Sea would gain a tool that simplifies planning, reduces aircraft inventory requirements, and shortens the kill chain against two of the most persistent threats below the waterline. The procurement notices on SAM.gov are only the opening move, but they point toward a future in which one helicopter and one sonar system could take on a job that today demands an entire squadron’s worth of specialized hardware.
