Combatant Craft Heavy (CCH) is a United States Special Operations watercraft developed to transport United States Navy SEALs, United States Marine Raiders, and other United States Special Operations Command elements for high-threat littoral and riverine missions. Designed for clandestine infiltration, secure logistics, and direct-action support, the CCH integrates lessons from operations in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation Inherent Resolve. It complements platforms such as the Mark V Special Operations Craft, Special Operations Craft-Riverine, and Naval Special Warfare fast boats.

Design and Development

Design and development drew on experience from Naval Special Warfare Command, United States Special Operations Command, Naval Surface Warfare Center, General Dynamics, Lockheed Martin, Austal USA, and private shipbuilders active in programs like Small Tactical Watercraft and Sea Frame Design projects. Requirements were shaped by doctrine from Joint Special Operations Command, operational feedback after Battle of Ramadi, and interoperability standards from NATO and U.S. Pacific Command. Prototyping used materials and methods consistent with programs such as Ship-to-Shore Connector and Littoral Combat Ship modularity, while survivability criteria referenced standards demonstrated in Operation Urgent Fury and analyses from Center for Naval Analyses.

Specifications

The CCH is approximately 85 feet in length with hull form influenced by Planing hull designs used on the Mark V Special Operations Craft and Patrol Coastal (PC) class. Propulsion options include waterjets and surface drives similar to those on Mk VI patrol boat and Cyclone-class patrol ship. Endurance and range specifications echo requirements from U.S. Africa Command and U.S. Central Command littoral operations. Navigation, communications, and mission systems align with equipment suites found in AN/PRC-117, AN/UPX-29, and standards from Defense Information Systems Agency and Program Executive Office C4I.

Operational History

CCH entered limited service after evaluation periods at Naval Amphibious Base Coronado, Naval Station Norfolk, and training at Special Warfare Combatant-craft Crewmen facilities. Exercises and deployments included participation in RIMPAC, Cobra Gold, and bilateral training with Royal Navy and Royal Australian Navy units. Missions supporting Operation Enduring Freedom and Operation Iraqi Freedom informed doctrine for counter-piracy patrols in coordination with Combined Task Force 151 and for interdiction missions connected to Operation Odyssey Dawn and Operation Unified Protector.

Variants and Modifications

Planned and fielded variants reflect mission-specific adaptations similar to conversions seen in the Mark V Special Operations Craft and Special Operations Craft-Riverine lines. Modifications include mission payload modules compatible with Navy Expeditionary Combat Command concepts, enhanced ballistic protection patterned after standards from Naval Sea Systems Command, and sensor suites integrating technology from Raytheon, Northrop Grumman, and BAE Systems. Logistic and medical packages mirror configurations used on USNS Mercy and USNS Comfort support conversions for expeditionary medical support.

Armament and Systems

Armament fits within doctrines established by Naval Special Warfare Command and procurement practices seen with the Mk VI patrol boat and Cyclone-class patrol ship, featuring machine-gun mounts similar to M240, M2 Browning, and remote weapon stations from Kongsberg Defence & Aerospace or Rafael Advanced Defense Systems. Sensor and electronic suites incorporate electro-optical/infrared systems used on platforms like MQ-8 Fire Scout and communications compatible with AN/PRC-117 and Link 16 where platform size permits. Defensive measures reference countermeasures and signature reduction techniques from Naval Research Laboratory research and survivability guidelines in Naval Vessel Rules.

Operators

Primary operators include elements of United States Navy Special Warfare Combatant-craft Crewmen and United States Marine Corps Forces Special Operations Command, with deployment under tasking by United States Special Operations Command and coordination with regional commands such as U.S. Central Command and U.S. Indo-Pacific Command. International interest and training exchanges involved partners including the United Kingdom, Australia, Japan Self-Defense Forces, and Philippine Navy units during combined exercises.

Incidents and Losses

Operational records cite accidents and incidents similar in profile to losses experienced by fast patrol craft during Operation Iraqi Freedom and other littoral campaigns; incidents prompted safety reviews overseen by Naval Safety Center and investigations coordinated with Naval Criminal Investigative Service when applicable. Lessons learned were integrated into training at Naval Special Warfare Group centers and shared in after-action reports with allied services such as Royal Navy and Royal Australian Navy.
