Design and Test of the Combat Rubber Raiding Craft
Abstract
The U.S. Navy H-60 Seahawk aircraft is routinely used in support of the Special Warfare community. In particular, operational squadrons are frequently tasked to insert SEAL personnel and equipment into hostile areas. For over-water missions, equipment to be carried and deployed includes weapons, ammunition, and the Combat Rubber Raiding Craft (CRRC). The CRRC is a specially fabricated inflatable raft measuring 15'5" by 6'3" and weighing up to 2,866 lb fully loaded. The CRRC contains eight airtight compartments and is designed to be operated by a crew of up to eight personnel using an outboard engine with a maximum rating of 65 Hp. The previous method for deploying the SEAL team, CRRC, and the equipment involved lowering personnel, the deflated CRRC and remaining equipment separately to the water via the rescue hoist, where the CRRC was subsequently inflated and loaded for the mission. NAWCAD engineers in conjunction with engineers from SEAL Team Training Group Two proposed and investigated several options for external carriage of the CRRC. One option involved fabrication of a Cargo Hook Restraint System (CHRS) that was attached to a single point on the aircraft via the aircraft cargo hook. The HH-60H platform team led the effort to design, fabricate, structurally analyze, and develop an operational flight envelope and deployment methods of this configuration. Successful completion of tests has resulted in providing an operational capability to the fleet operators, allowing deployment of the Special Warfare personnel, with a full loaded CRRC, in approximately 30 sec vice the previous 30 min.
