The F470 Combat Rubber Raiding Craft (CRRC) is an inflatable „Zodiac” boat which can be both paddled or powered by outboard motors. CRRCs are stealthy, especially when paddled, lightweight and easily stowed when deflated. They can be launched from submerged submarines or air-dropped from helicopters or medium-lift transport aircraft. A single F470 can be inflated to its complete size within 2 minutes through pressurized air from a SCUBA tank. The CRRC can be used for both "blue" (open water) or "brown" (riverine) water missions and is fully-capable of transporting up to ten combat-ready Special Forces operatives.
The Rigid Hull Inflatable Boat (RHIB) is a high-speed, high-buoyancy, extreme-weather craft with the primary mission of SEAL insertion/extraction and a secondary mission of marine interdiction operations.
The Special Operations Craft - Riverine (SOC-R) is designed as a high speed boat with ample weapons and equipment capacity. The mission of the SOC-R craft is to perform Short Range Insertion (SRI) of Special Operation Forces in a riverine environment. The capacity of the boat allows forces to conduct extended operations in waterways that are located well inland. It is also air-transportable.
The Mark V Special Operations Craft is used to carry Special Operations Forces (SOF), primarily SEAL combat swimmers, into and out of operations where the threat to these forces is considered to be low to medium. They also support limited coastal patrol and interruption of enemy activities.
The Landing Craft, Air Cushion (LCAC) is a high-speed, over-the-beach, fully amphibious landing craft, capable of carrying a 60-75 ton payload. It is used to transport the weapons systems, equipment, cargo and personnel of the assault elements of the Marine Air-Ground Task Force from ship to shore and across the beach. LCAC can carry heavy payloads, such as an M1 tank, at high speeds. The LCAC payload capability and speed combine to significantly increase the ability of the Marine Ground Element to reach the shore. Air cushion technology allows this vehicle to reach more than 70 percent of the world's coastline, while only about 15 percent of that coastline is accessible by conventional landing craft.
The LCU 1646 transports wheeled and tracked equipment and general cargo from ship to shore, shore to shore, and in retrograde operations. Although the Navy now has a newer craft, the Landing Craft Air Cushion (LCAC), the LCUs have the backbone for heavier loads. Its development and design updated the landing craft used in World War II, made famous by the invasion of Normandy Beach. However, it requires a 9 foot draft beneath its keel to operate safely, making it less versatile than the LCAC, which flies on top of water or ground. Another difference between the two landing craft is the LCU is home away from home for its crew, because it can operate independent of the amphibious ships on which it embarks. It contains living compartments that include sleeping quarters, a wash room with shower, a clothes washer and dryer, a lounge and a complete galley, making them able to operate at sea for up to 10 days. LCUs have both bow and stern ramps for onload/offload.
The LCU 2000 moves containers, general or vehicular cargo. This includes missions in LOTS (logistics-over-the-shore) operations in remote areas with austere shore facilities or unimproved beaches. The LCU 2000 is also suitable for the intratheater movement of cargo and unit equipment along coastlines or inland waterways. It is used for unit deployment and relocation. It has a bow ramp and a bow thruster to assist in beaching and beach extraction. Because of its shallow draft, the LCU 2000 can carry cargo from deep draft ships to shore ports or areas too shallow for larger ships.
The primary mission of Mark VI Patrol Boats is to provide capability to persistently patrol littoral areas beyond sheltered harbors and bays for the purpose of force protection of friendly and coalition forces and critical infrastructure. These missions include: security force assistance (SFA); high value unit (HVU) shipping escort; visit, board, search, and seizure (VBSS) operations; and theater security cooperation (TSC)
The Riverine Command Boat (RCB) is capable of offering command and control for a range of situations. RCBs can execute a variety of operations across all phases of military operations, including port security, troop insertion or extraction, inland counter-insurgency operations, organic air and fire support, organic unmanned aerial vehicle support, maritime interdiction, and command and control. RCBs serve as part of a Coastal Riverine Force (CRF) unit, acting as liaison between shallow water riverine units and standard deep-water naval vessels.
