U.S. Navy Orders Up to 474 Composite RHIB Boats in $650M Maritime Operations Expansion.

The U.S. Navy has awarded a $325.9 million contract to eight domestic shipbuilders to procure up to 474 rigid-hull inflatable boats, according to a U.S. Department of War (Department of Defense) announcement published on April 30, 2026. The award strengthens the Navy’s ability to operate in fast-moving coastal battlespaces, expanding its fleet of high-speed small craft for maritime security, special operations insertion, and rapid response in contested littoral zones where larger vessels are more vulnerable, particularly in regions such as the Indo-Pacific.

These composite-hull boats deliver speed, maneuverability, and shallow-water access, enabling dispersed naval units to patrol, interdict, and support missions closer to shore. The investment reflects a broader shift toward distributed maritime operations, where smaller, agile platforms enhance survivability and sustain operational pressure in complex coastal environments.

The contract, announced by the U.S. Department of War (Department of Defense) on May 1, 2026, is managed by the Naval Sea Systems Command and was competitively tendered through the Procurement Integrated Enterprise Environment, with 15 offers received. Initial deliveries are expected by July 2026, supporting near-term fleet readiness while enabling scalable expansion of small craft capacity across multiple operational theaters.

The selected manufacturers include ASIS Boats USA doing business as Ocean Craft Marine, Brig USA doing business as Fluid Marine Response, Ghostworks Marine, Ribcraft USA, St. Johns Ship Building, Structural Composites, United States Marine Inc., and The Whiskey Project Group. Their distribution across U.S. coastal and inland industrial hubs strengthens production resilience and supports sustained output of mission-ready boats under a flexible acquisition framework.

A composite rigid-hull inflatable boat, commonly referred to as RHIB, is a high-speed military craft built around a solid, lightweight hull made from advanced composite materials combined with inflatable tubes along the sides. This configuration provides a unique balance of structural strength, buoyancy, and shock absorption, allowing the boat to maintain stability at high speeds and in rough sea conditions. The rigid hull, often designed with a deep V shape, improves hydrodynamic efficiency and enables rapid maneuvering, while the inflatable collar enhances survivability by offering additional flotation and impact protection during boarding or alongside operations.

RHIBs are typically powered by high-output outboard or inboard engines, enabling speeds exceeding 40 knots depending on configuration and payload. Their modular layout allows integration of navigation radars, secure communications systems, weapon mounts, and mission-specific equipment. This adaptability makes them suitable for a wide range of naval tasks, including visit, board, search, and seizure operations; troop insertion; maritime interdiction; search and rescue; and harbor security.

Operationally, these boats are heavily used by Navy expeditionary forces, coastal riverine units, and special warfare teams. Their shallow draft allows access to confined waterways, river systems, and coastal zones that are inaccessible to larger surface combatants. This makes RHIBs essential for missions in archipelagic regions and urban littorals where control of the near-shore environment is decisive.

The indefinite-delivery and indefinite-quantity structure of the contract allows procurement to scale over time, with a potential ceiling value of $650.1 million across ten years if all options are exercised. Only minimal initial funding is obligated at award, with the majority allocated through future delivery orders, ensuring that production aligns with evolving operational requirements and budget priorities.

From a strategic perspective, the expansion of the RHIB fleet supports the U.S. Navy’s emphasis on distributed maritime operations. By deploying a larger number of small, fast, and networked boats, naval forces can increase presence, complicate adversary targeting, and sustain persistent operations in contested coastal zones. This approach enhances deterrence by improving responsiveness and enabling rapid concentration of force at critical points.

Strengthening the fleet of composite rigid-hull inflatable boats reflects a broader shift toward flexible, high-mobility maritime capabilities. As potential conflicts increasingly focus on littoral regions and hybrid threats, the ability to deploy versatile small craft at scale provides the U.S. Navy with a critical operational advantage in securing sea lines of communication, protecting infrastructure, and supporting joint force operations.
