Problem

The cost-exchange ratio for detecting and neutralizing asymmetric maritime threats in contested environments is heavily skewed in favor of the adversary. Bad actors deploy low-cost, low-signature threats—including explosive Unmanned Surface Vessels (USVs), Group 1–3 Unmanned Aircraft System (UASs), "go-fast" smuggling boats, and semi-submersibles.

Currently, the Department of War (DoW) relies on exquisite, multi-million-dollar naval and aviation assets to intercept these inexpensive targets. The Government requires affordable, scalable, production-ready maritime systems capable of persistent search, tracking, and operational effects against asymmetric threats. The Government seeks innovation combinations of USVs and UASs that maximize operational effectiveness while improving the cost-exchange ratio across a range of mission profiles.

Solution

The Government and the Department of War Innovation Unit (DIU) seek to partner with established maritime manufacturers, autonomy developers, sensor manufacturers, and UAS developers to execute a multi-phase Prize Challenge under 10 USC 4025 with up to $100M in available funding.

The DoW is relying on industry to provide inexpensive and scalable solutions that combine proven USVs with mature drone capabilities to extend sensing, targeting, communications, and defeat of hostile threats through kinetic and non-kinetic effects at scale.

This competition will be executed as a 12-Month Prize Challenge with rolling submission windows divided into three Sprint cohorts. In order to be considered for Sprint 1, submissions must be received by 8/10/2026 @ 2359 EST. Future submission windows will be published after the completion of Sprint 1. See “Challenge Series & Rolling Sprints” for additional details.

Desired Solution Attributes

The Department of War (DoW) seeks mature, market-ready USVs fully integrated with two or more mature, market-ready aerial drones to detect, identify, track, and defeat hostile threats. This program aims to fill a critical gap in low cost sensing and defeat within the maritime environment.

The USV solution must demonstrate a minimum operational range of 200 nautical miles and a sustained cruise speed of at least 10 knots. These values represent threshold requirements for consideration; however, the government seeks the highest-performing solutions, and top performers are expected to substantially exceed these minimums.

The USV solution should enable the following operations:

Carry, launch, control, and employ a minimum of two UAS, collectively capable of kinetic strike with a minimum 2kg payload and battle damage assessment (BDA). The UAS should include multiple system types to include a mix of recoverable/reusable and single use/one-way attack (OWA). The UASs should be technically mature and have an established production line.
Navigation to user-defined waypoints, patrol designated areas, loiter on station, and reposition in response to operator commands or mission objectives.
Safely operate in blue water, littoral, and brown water environments.
Detect, identify, and track surface targets using onboard sensors and/or launched drones, providing operators with real time situational awareness and the ability to direct drone employment as required.

The UAS solution should enable the following operations:

Seamless launch from the USV.
If utilizing expendable or loitering munitions, the design emphasizes a low cost per operational effect and fail-safe mission-abort protocols to prevent unexploded ordnance hazards.
Detect, classify, and maintain persistent custody of threats at extended ranges. Drones should support one or more operational effects, including ISR, comms relay, electronic warfare, payload delivery, or precision engagement of moving or stationary, as applicable, under operator command.
If recoverable, the UAS should be capable of safe and repeatable recovery aboard the USV while underway and in representative sea states with minimal operator intervention

Desired Primary Attributes

Persistent Area Search and Interdiction

The solution provides persistent, low-cost autonomous surveillance and interdiction of defined maritime operating areas, maximizing operational coverage, probability of detection, interdiction effectiveness, and time on station while minimizing daily operating cost, logistics burden, and required personnel. Solutions that deliver greater sustained area coverage and operational effectiveness at lower cost will be evaluated more favorably.

UAS System Operations

Able to carry, launch, control, and employ a minimum of two UAS, one of which must carry a 2kg+ kinetic payload. Solutions should demonstrate reliable integration between the USV, UAS, sensors, and C2 systems. All engagement capability is desired to be capable of remote operation, with appropriate safety measures such that the USV may be recovered and reused. The USV and all embarked UAS assets shall support First Person View (FPV) Beyond Line of Sight (BLOS) operations, enabling operators to maintain positive control of both maritime and airborne assets throughout mission execution. Solutions that support larger onboard drone quantities, higher payload capacity, sortie generation rates, or generate effects against both maritime surface threats and low-altitude airborne threats will be viewed favorably during evaluation. The Government encourages offerors to propose innovative mixes of UAS classes and employment concepts that optimize mission effectiveness. Solutions may combine reusable, attritable, and expendable aircraft of differing payload capacities, ranges, endurance, and operational roles where doing so improves overall system performance.

Mature System

Solutions must include a complete mission ready USV with integrated drone capability system available for testing and evaluation within 29 days of down-selection for Sprint 1. Solution briefs must address prior operational demonstrations, system maturity, proven integration, command-and-control architecture, and TRL. The Government is seeking production-ready capabilities and is not interested in conceptual designs, developmental efforts, or prototype-only solutions. Offers must demonstrate an established manufacturing capability and active production line for both the USVs and UASs. Solutions demonstrating greater production, scalability and surge capacity will be viewed more favorably during evaluation. Industry partnerships and teaming arrangements that are not sufficiently mature in time for the September evaluation may be considered during subsequent evaluation windows.

Open Architecture and Teaming

Solutions should leverage market-ready technologies and support modular integration of UAS, sensors, payloads, and software from multiple vendors. The Government encourages teaming arrangements that combine mature USV platforms with proven drone capabilities and other best-of-breed technologies to deliver an integrated, mission-ready solution. Solutions that demonstrate integration and operational employment of multiple drone types from different manufactures will be viewed favorably during evaluation. Open, interoperable architectures that enable rapid integration of new payloads, sensors, and autonomous capabilities over time are highly encouraged.

Desired Secondary Attribute(s)

Low Burden Logistics

Able to be moved and launched via standard vehicles without specialized equipment and transportable via common cargo containers such as a forty-foot equivalent unit (FEU), on common cargo aircraft (e.g., C-17 or C-130), and road trailers. Solutions that can launch from unimproved locations or provide additional launch flexibility, i.e. remotely from a container, will be looked upon favorably.

Resilient Comms and Localization

Able to operate in various degrees of denied, disrupted, intermittent and limited (DDIL) conditions. Systems must have resilient communications pathways to operators at various ranges to allow for direct operator supervision and be able to localize in environments where Global Navigation Satellite System (GNSS) may be denied, degraded or spoofed for indeterminate periods of time.

Autonomous Maritime Operations

USVs and drones should be able to autonomously navigate to user-defined waypoints, patrol designated areas, loiter on station, autonomously follow or shadow a vessel of interest, and autonomously intercept a noncooperative, maneuvering vessel. Autonomous execution of these functions is desired but not required.
