USS Cleveland enters service as Navy advances distributed maritime operations

Built by Lockheed Martin at the Fincantieri Marinette Marine shipyard in Marinette, Wis., Cleveland is the 16th and final Freedom-variant littoral combat ship constructed for the Navy. The vessel will be homeported at Naval Station Mayport, Fla.

Key Highlights

  • USS Cleveland is the final Freedom-variant LCS, representing the Navy's shift toward modular, software-defined, and network-centric naval warfare capabilities.
  • Equipped with advanced radar, combat management, and networking systems, Cleveland supports surface warfare, mine countermeasures, and integration with uncrewed platforms.
  • The ship's design emphasizes high-speed maneuverability, with waterjet propulsion allowing speeds over 40 knots in littoral environments.

CLEVELAND - The U.S. Navy commissioned the Freedom-variant littoral combat ship USS Cleveland (LCS-31) on 16 May 2026, formally placing into active service one of the Navy's most networked and modular small surface combatants and closing out a major chapter in the service's push toward software-defined, network-centric naval warfare.

Although the Littoral Combat Ship program faced years of scrutiny over survivability, mission effectiveness, and lifecycle costs, the USS Cleveland enters service as a showcase for many of the technologies now shaping the Navy's future distributed maritime operations strategy, including modular payloads, uncrewed systems integration, advanced tactical networking, and software-defined combat systems.

The Freedom-variant littoral combat ship architecture was designed around speed, automation, and mission flexibility for operations in contested coastal waters. Cleveland is equipped with modular mission packages that integrate crewed and uncrewed platforms, sensors, and weapons systems for surface warfare and mine countermeasures missions.

Among the ship's most important technologies is the COMBATSS-21 combat management system, a software-defined architecture derived from the Aegis combat system. The system integrates radar, electronic warfare, tactical data links, and aviation assets into a common operational picture intended to improve sensor fusion and real-time decision-making.

Cleveland also incorporates the TRS-4D active electronically scanned array radar system, designed to improve simultaneous air and surface target tracking in cluttered littoral environments. AESA radar technology enables faster beam steering, improved reliability, and better tracking performance against small surface threats and low-signature targets.

Advanced networking

The ship also incorporates advanced networking capabilities that enable it to operate as part of a larger distributed naval force alongside cruisers, destroyers, aircraft, and uncrewed systems. Navy officials have increasingly emphasized this type of networked warfare concept as part of future fleet modernization efforts.

Cleveland's onboard technologies include aviation systems capable of supporting the MH-60R Seahawk helicopter and MQ-8C Fire Scout uncrewed helicopter, extending the ship's intelligence, surveillance, and reconnaissance reach beyond the horizon.

The ship's modular mission systems architecture also supports integration of technologies such as uncrewed surface vessels, mine-hunting sensors, Naval Strike Missile systems, and the MK-70 Payload Delivery System.

Designed for high-speed maneuverability in littoral environments, the Freedom variant features a steel monohull with waterjet propulsion, capable of exceeding 40 knots. The ship measures 387.6 feet long with a displacement of approximately 3,450 metric tons at full load.

The Littoral Combat Ship program began in 2002 as part of a Navy effort to develop fast, modular surface combatants capable of operating in near-shore environments against asymmetric threats, including mines, small boats, submarines, and uncrewed systems. The program ultimately produced two variants: the Freedom-variant monohull, built by Lockheed Martin, and the Independence-variant trimaran, built by Austal USA.
