Saildrone Runs Navy Drones in the Caribbean, Yet Locked Out of the $2.1 Billion Fleet

Two Companies, One Complaint: The Navy Broke Its Own Rules

Two maritime autonomy firms have sued the U.S. Navy, alleging the service violated its own procurement rules when it shut them out of a $2.1 billion program to field medium-size unmanned surface vessels, Breaking Defense reported. The lawsuits, filed in late June and unsealed in mid-July, argue that both companies met every mandatory requirement the Navy published, yet were excluded from at-sea testing while seven other contractors moved forward.

The challenge lands at a fragile moment for the Navy's unmanned ambitions. In March, the service canceled its Modular Attack Surface Craft program, a prototyping effort that had already selected Blue Water Autonomy's vessel through a multi-stage evaluation. The Navy said MASC was no longer needed because mature platforms existed to move straight to production. It replaced MASC with the Medium Unmanned Surface Vessel marketplace, a rapid-acquisition vehicle funded by the "One Big Beautiful Bill" that passed in July 2025. Submissions were due under a March 2026 request for proposals that specified hard performance thresholds: carry at least two 40-foot shipping containers, travel 2,500 nautical miles at 25 knots in sea state 4 with a 25-metric-ton payload.

Saildrone and Blue Water Autonomy both submitted designs. Neither was invited to the June down-select that advanced Leidos, Huntington Ingalls Industries, Saronic, Sea Machines, Galliano Marine Services, PacMar Technologies, and Birdon to prototype testing slated to wrap in October. Participants who complete testing receive $15 million and qualify for follow-on production contracts.

The complaints paint a picture of a process that changed after proposals were in hand. Blue Water Autonomy, backed by investors including Google Ventures, argues the Navy "arbitrarily and prematurely excluded" it from further consideration rather than allow its surrogate vessel to demonstrate compliance. The firm says it made significant financial investments based on the Navy's stated objective of using commercial innovations to procure the next generation of autonomous vessels. Saildrone's complaint is more granular: its Spectre design, a 52-meter vessel with a concealed payload deck capable of holding two 40-foot containers or up to five 20-foot containers, "satisfied or exceeded every mandatory acceptability criterion" and had earned American Bureau of Shipping certification in December 2025. The company had ordered long-lead components in late 2025 to support fiscal 2027 fielding. It learned it had been cut from a public news story; the Navy notified Saildrone only after the company asked for details.

Both complaints allege the Navy's portfolio acquisition executive for robotic and autonomous systems accepted other proposals "notwithstanding design-maturity, fielding, manufacturing-readiness, or test readiness issues more significant than the issues RAS cited against Saildrone." The specific deficiencies the Navy cited remain redacted in the unsealed filings.

The relief sought differs. Blue Water Autonomy wants an injunction halting the at-sea testing and all follow-on production funding until the Navy reassesses its proposal "reasonably and in accordance with the RFP and existing law" and allows Blue Water to complete testing. Saildrone seeks reevaluation consistent with the solicitation but explicitly does not ask the court to pause the ongoing test event for other participants. "The requested relief instead would require RAS to evaluate Saildrone lawfully and, if Saildrone is found acceptable, permit Saildrone to participate without disrupting the broader test schedule," its complaint states.

Saildrone shared a draft complaint with the Department of Justice in June in an attempt to resolve the matter without litigation. The Navy declined to reevaluate. A Navy spokesperson told Breaking Defense the service does not comment on pending litigation. Blue Water Autonomy referred inquiries to its complaint.

Why This Program Matters: 81 Hulls, One Hybrid Fleet

The Navy's Medium Unmanned Surface Vessel program isn't just another line item in a budget request exceeding $300 billion across the FYDP. It's the service's primary bet on a hybrid fleet that mixes crewed warships with autonomous platforms — and the $2.1 billion appropriated in the July 2025 legislation is the down payment on 81 vessels by fiscal 2031.

That procurement profile, detailed in the Navy's most recent shipbuilding plan, is aggressive: 36 MUSVs in FY26 alone, then three in FY27, ten each in FY28 and FY29, and twelve per year in FY30 and FY31. Another $3.1 billion is programmed across the Future Years Defense Plan for 47 additional hulls from FY27 through FY31. By the early 2030s, the Navy projects 83 unmanned vessels of all types in active service — more than the auxiliary fleet it operates today.

The strategic driver is the Indo-Pacific. Chief of Naval Operations Adm. Daryl Caudle has argued that unmanned systems serve as force multipliers that reduce risk to sailors while expanding capacity — the core of his Hedge Strategy, released in February 2026, and the Distributed Maritime Operations concept that has guided Navy planning for years. "When paired with manned platforms, unmanned systems expand capacity and provide increased flexibility that is central to the success of Distributed Maritime Operations," Caudle told lawmakers in July. "The Navy is building a mix of high-end warfighting systems and affordable, attritable and attainable systems that provide mass and scale to challenge our adversaries."

The marketplace model itself is a departure. Rather than funding prototypes, the Navy is asking industry to bring production-ready designs — shifting development cost and schedule risk to contractors. Rebecca Gassler, in that role, described the prior Modular Attack Surface Craft program as a "prototyping effort" that became unnecessary once mature platforms existed on the market. "Because industry has leaned forward and has built boats or has built the technology already… we no longer needed to go through the prototyping phase," she told reporters in March. "So this will allow us to test the capability on water and go straight into production. And that will save us approximately on, you know, on the order of a year, and we will get capability to the fleets faster."

The timeline leaves no margin. At-sea testing for the seven selected vendors (Birdon, Galliano Marine Services, Huntington Ingalls Industries, Leidos, PacMar Technologies, Saronic Technologies, and Sea Machines) began in June and must conclude by September 30, the end of FY26. The first production vessel is contractually due in FY27. Gassler has called this "the first of what will be a recurring marketplace," with plans to apply the same model to other vessel classes. A follow-on solicitation for a high-capacity logistics MUSV was already posted in July.

Leidos's Seahawk, already in the operational fleet since April, is slated to deploy with the USS Theodore Roosevelt carrier strike group. Huntington Ingalls offers the Romulus line powered by its Odyssey autonomy stack. Saronic's 180-foot Marauder claims 5,400 nautical miles range and 150-metric-ton payload capacity. Birdon partnered with Mythos AI in April; PacMar teamed with HavocAI in May. Galliano Marine Services secured two concept selections.

The lawsuit now threatens to freeze that testing window. If a court enjoins the program, the Navy loses its summer test period — and with it, the only path to FY27 production deliveries under the current solicitation. The stakes aren't theoretical: they're measured in hulls that won't reach the fleet on schedule, and a hybrid fleet architecture that stalls before it scales.

How the Navy Evaluated Bids: And Why the Process Is Contested

The Navy ran the Medium Unmanned Surface Vessel competition through an Other Transaction Authority agreement managed by NAVSEA headquarters, a mechanism designed to move faster than traditional Federal Acquisition Regulation procurements. The solicitation, N00024-26-R-6326, asked offerors to submit four components by April 17, 2026: a business model (contractor-owned or government-operated), a vessel design meeting threshold requirements and desired attributes, manufacturing readiness documentation for future production, and a test execution plan. Evaluation weighted three pillars: technical merit, manufacturing readiness, and test plan feasibility, with cybersecurity compliance under NIST SP 800-171 baked in as a pass-fail gate. Proposals were limited to 10 MB per email, sent to contracting officers Cassandra Brese and Kevin Hubbard. The Navy framed the effort as a prototype test culminating in an on-water demonstration no later than September 30, 2026, with awards up to $15.01 million for successful completion and follow-on production contracts available for qualifiers.

Seven vendors cleared that first cut and advanced to the prototype evaluation phase, a figure confirmed by Navy officials in late May 2026. The exclusion of Saildrone and Blue Water Autonomy — both of which field operational medium-class USVs and hold Navy-relevant certifications — triggered the protest. Saildrone's Surveyor carries full ABS classification, a credential the Navy has signaled will become a procurement gatekeeping mechanism as unmanned vessel safety standards formalize. Saronic is pursuing ABS classification under an active memorandum of understanding; vendors without a clear certification pathway face increasing regulatory exposure. Blue Water Autonomy, meanwhile, holds a program of record for its Liberty class vessel, with hull production underway at Conrad Shipyard in Louisiana since March 2026 and first delivery expected later this year. Its chief strategy officer has stated publicly that Liberty met or exceeded every MASC requirement, the predecessor program cancelled on March 26, 2026.

The contestation centers on three friction points. First, the timeline: the April 17 proposal deadline left less than seven months before the mandated on-water test, a window that disadvantages vendors whose hulls were not already in construction. Blue Water Autonomy's Liberty keel was laid in March; the test deadline arrives before its first hull can complete trials. Second, the evaluation criteria's emphasis on "manufacturing readiness for future production" and "depth of private industry investment" favors companies with disclosed government-backed production lines (Saronic's $392 million OTA for Corsair production, obligated at nearly $200 million in December 2025, and its $300 million Franklin facility expansion) over privately capitalized entrants that have not yet secured a Navy production contract. Third, the recurring marketplace structure itself: the Navy intends to run successive competition rounds, and vendors that qualify early accrue incumbency advantages across future iterations. Missing the first round is not a temporary setback; it compounds.

Saildrone has formally requested reinstatement and entry into the on-water test. Blue Water Autonomy's private-capital development model aligns with what Navy leadership and the current administration have encouraged, yet its youth as an organization (founded 2024) and lack of open-ocean autonomous demonstration to date may have weighed against it in the manufacturing readiness assessment. Neither company has disclosed the specific debrief findings that triggered the lawsuit, but the protest signals a fundamental disagreement over how the Navy balanced demonstrated at-sea performance against paper production plans in a competition where the clock started before the rules were fully settled.

The Competitive Landscape: Seven In, Two Out

Leidos enters with deep roots in Navy autonomy. The company has managed the Ghost Fleet Overlord program, converting commercial fast transports into unmanned surface vessels for the Pacific Fleet. HII brings shipbuilding scale (Ingalls and Newport News yards, plus the REMUS UUV line) and a track record of moving prototypes to programs of record. Saronic has positioned itself as a software-first builder; its pitch centers on rapid iteration and attritable cost curves. All three have production pathways the Navy can audit.

The broader USV market counts 63 companies globally (Sagar Defence Engineering, General Dynamics Mission Systems, and Seasats among the top tier) but the MUSV marketplace narrowed to production-ready platforms. That filter is the rub. Saildrone's complaint repeats the allegation that the Navy accepted other proposals "notwithstanding..." more significant issues than those cited against Saildrone. If discovery bears that out, the competitive landscape the Navy tried to curate may look less like a meritocracy and more like a procurement bottleneck with a litigation problem attached.

What the Lawsuits Actually Argue

The core allegation is straightforward: the Navy ran a competition, published criteria, then ignored its own rules when the results didn't suit it.

Blue Water's complaint centers on the Modular Attack Surface Craft program. The Navy selected the company's Liberty vessel for MASC through what the complaint calls a "multi-stage process" before canceling that program in March and replacing it with the MUSV marketplace. Blue Water argues the Navy "arbitrarily and prematurely excluded Blue Water from further consideration" rather than letting it test the surrogate vessel that would have demonstrated compliance with MUSV requirements. The company says it had already sunk millions into the Liberty prototype. Its filing asks the court to halt at-sea testing and follow-on funding until the Navy reassesses Blue Water's proposal "reasonably and in accordance with the RFP and existing law."

Saildrone takes a different tack. The company was already participating in the MUSV process when it was cut. Its complaint states the Spectre design "satisfied or exceeded every mandatory acceptability criterion" and had earned American Bureau of Shipping certification in December 2025. Saildrone had ordered long-lead components in late 2025 targeting a fiscal 2027 fielding. The company learned it had been excluded not from the Navy but from a public news article. Only after Saildrone asked for details did the service send a four-sentence email stating the proposal "was not selected for further consideration under this solicitation" — with no explanation tied to the published criteria.

Both complaints allege the Navy applied "overly restrictive evaluation criteria" and reached "irrational conclusions that are inconsistent with the [Request for Prototype Proposals] and statutory requirements." Saildrone's filing goes further, quoting the earlier "notwithstanding..." language to allege that RAS accepted other proposals despite more significant deficiencies than those cited against Saildrone. That official — referred to as RAS in the complaints — is named as the decision authority.

The procedural grievances mirror each other. Neither company received a debriefing that mapped the Navy's findings to the solicitation's evaluation factors. Saildrone shared a draft complaint with the Department of Justice in June seeking resolution without litigation; the Navy declined to reevaluate. Blue Water's complaint uses the word "capricious" to describe the exclusion.

The requested relief diverges. Blue Water wants an injunction stopping the entire test event and funding allocation until its proposal gets a lawful review. Saildrone explicitly does not seek to delay other participants. Its complaint states: "The requested relief instead would require RAS to evaluate Saildrone lawfully and, if Saildrone is found acceptable, permit Saildrone to participate without disrupting the broader test schedule."

The Navy has not responded substantively. A spokesperson told multiple outlets the service does not comment on pending litigation. The PAE RAS's specific rationale for rejecting both the Liberty and Spectre designs remains redacted in the public filings.

What a Delay Could Mean: Hulls That Don't Arrive

In April 2025, Navy leadership merged the separate LUSV and MUSV efforts into a single "Future USV" initiative, targeting formal development start in FY27 with requirements finalization expected by late 2025. The consolidation was driven by spiraling costs: GAO reports show the lead LUSV's projected cost has increased over 80% since program inception, with the first production vessel now delayed from FY25 to FY27 at an estimated $497.6 million per hull. The Orca XLUUV program sits at 64% over budget and three years behind schedule. The MUSV marketplace, funded by roughly $2.1 billion from the July 2025 legislation, was meant to demonstrate that mature commercial platforms could move quickly to production, a proof point for the Future USV logic. A protracted legal fight undermines that proof point.

The strategic stakes are tied to the Indo-Pacific. The distributed fleet concept specifically addresses China's anti-access strategy, but success requires sufficient numbers to create tactical advantage. Congressional Budget Office analysis warns that distributed fleet savings evaporate if these vessels become expensive one-offs rather than mass-produced platforms. The Navy's FY27 budget calls for procurement of 63 unmanned vessels across programs. If MUSV delays cascade into Future USV requirements finalization (currently targeted for late 2025), the service risks fielding token unmanned forces insufficient for strategic effect while peer competitors advance their own capabilities. Australia's Ghost Shark XLUUV and the UK's Herne unmanned submarine project are already leveraging similar technologies for regional operations.

Current operations offer a glimpse of what's at stake. As of February 2025, 20 Saildrone Voyagers were at sea supporting Navy operations in the Caribbean and Eastern Pacific under a counter-drug mission renewed in August 2026 with a $16.3 million task order extending into 2027. The Voyager, capable of 100-day endurance, conducts intelligence, surveillance, and reconnaissance as well as near-shore mapping and seabed surveys. Sixteen additional Voyagers are deploying to the Great Lakes and North Atlantic for Coast Guard border security and illegal fishing patrols. Chief of Naval Operations Adm. Daryl Caudle has said SOUTHCOM will serve as a "test bed" for the service's hedge strategy, investing in autonomous systems for "sea denial and global seabed control." Those operational lessons feed directly into MUSV and Future USV requirements. A delay in the formal program slows the feedback loop between today's experiments and tomorrow's fleet.

Congress holds appropriations authority and has signaled conditional support through FY26 defense bills, but lawmakers demand concrete evidence of cost control and capability delivery. The House Armed Services Committee requires quarterly progress reports and independent cost assessments before releasing procurement funding. A lawsuit-driven delay that pushes prototype testing past October 2026 could force the Navy to brief Congress on schedule slippage before requirements for the consolidated Future USV are even locked. That sequence — legal challenge, testing delay, requirements slip, Congressional scrutiny — is how acquisition programs enter the "cautionary tale" territory the Navy has tried to avoid since the Littoral Combat Ship's modular mission packages produced decades of cost overruns and capability gaps.

Can the Navy Manage the Legal Hurdles?

The Navy faces a compressed timeline and a binary choice: litigate or accommodate. The lawsuits, filed in the U.S. Court of Federal Claims at the end of June and unsealed in mid-July, ask for different remedies. Blue Water Autonomy wants the court to enjoin the service from completing at-sea testing and obligating the full $2.1 billion in follow-on production funding until the Navy reassesses its proposal "reasonably and in accordance with the RFP and existing law," according to the complaint. Saildrone, by contrast, seeks a narrower order compelling reevaluation of its Spectre design without pausing the ongoing test event for the seven selected firms.

That split gives the Navy maneuvering room. If the court denies Blue Water's injunction request, the service can proceed with the October test wrap-up while litigating the merits. If the court grants it, the entire MUSV marketplace (funded through the "One Big Beautiful Bill Act" passed in July 2025) could freeze. The fiscal 2027 budget already calls for procuring 63 unmanned vessels, a number that assumes MUSV delivers prototypes on schedule.

Gassler justified the March cancellation of the Modular Attack Surface Craft program by telling Defense News the service determined "there were enough mature platforms to move into production." That rationale now cuts both ways. Blue Water's complaint notes the Navy had already selected its Liberty vessel for MASC and "evaluated Blue Water's vessel solution through a multi-stage process" before canceling the program. Saildrone's complaint points out its Spectre design held American Bureau of Shipping certification since December 2025 and had long-lead components ordered for FY27 fielding. Both argue the Navy's own evaluation record contradicts the exclusion decisions.

Chief of Naval Operations Adm. Daryl Caudle acknowledged the friction in March at a CSIS event: "I get equally frustrated with the number of times we've tried to start doing modules in the Navy." His frustration signals leadership awareness but doesn't translate to a legal strategy. The Navy has declined to comment on pending litigation, a standard posture that preserves appellate options but surrenders the public narrative to the plaintiffs.

Three practical paths exist. First, the Navy could voluntarily reevaluate both proposals (Saildrone offered this resolution in June via a draft complaint shared with the Department of Justice) mooting the injunction motions and preserving the test schedule. Second, it could oppose the injunctions aggressively, arguing that halting a $2.1 billion program critical to Indo-Pacific distributed operations harms national security. Third, it could seek a stay of any injunction granted, buying months of appellate review while testing continues.

The second path carries risk. Courts routinely grant injunctions when a plaintiff shows likely success on the merits and irreparable harm. Blue Water's prior MASC selection and Saildrone's ABS certification and 2.5 million operational nautical miles since 2012 constitute evidentiary weight. The Navy would need to demonstrate its evaluation followed the March RFP's stated criteria — a showing the complaints allege it cannot make.

The first path (voluntary reevaluation) aligns with Saildrone's stated position that "advancement to the on-water test event imposes no material financial obligation on the government." It also mirrors the Navy's own hedge strategy, visible in the $16.3 million SOUTHCOM task order extension for Saildrone announced in August and the Danish Armed Forces' operational trial of four Voyager USVs. The service is already buying Saildrone capability outside MUSV; excluding it from MUSV looks inconsistent.

Whichever path the Navy chooses, the October test deadline is the forcing function. A court ruling on the injunctions will likely precede it. If the Navy wants 63 unmanned vessels in FY27, it needs the marketplace mechanism functional by late 2026. Litigation that extends into 2027 breaks that chain.

The ghost fleet's first stress test isn't at sea. It's in a courtroom, where the service's own rules are on trial — and the clock is running.
