HH-47 Combat Search and Rescue (CSAR-X)
On 09 November 2006 the Boeing Company’s HH-47 helicopter has been selected by the U.S. Air Force as the winner of the Combat Search and Rescue (CSAR) program competition. The CSAR program calls for initial operational capability of the HH-47 aircraft in 2012. Under the program, which is valued at up to $10 billion, Boeing will build 141 production aircraft and four test aircraft at its Rotorcraft Systems manufacturing facility in Ridley Park, Pa., also home to the MH-47G Special Operations and CH-47F Chinook programs.
"The CSAR award is a vote of confidence by the Air Force in the ability of Boeing to provide them the rotorcraft they need for this very important mission," said Jim Albaugh, president and chief executive officer of Boeing Integrated Defense Systems. "Backed by our decades of experience in rotorcraft design, production and systems integration, the HH-47 will rapidly deploy versatile rescue capability to even the most challenging combat rescue situations."
In September 2005 the Boeing Company announced its entry in the U.S. Air Force combat search and rescue aircraft program, the advanced HH-47 CSAR-X tandem rotor aircraft. The HH-47 Boeing is offering to the US Air Force is a combat proven and technologically proven solution. This option is in line with Boeing's vision of being the preferred supplier, integrator and teammate of the Air Force customer.
Built on a new airframe, the Boeing HH-47 CSAR-X rescue aircraft is equipped with advanced countermeasures and survivability enhancements similar to those utilized in U.S. Special Operations MH-47G heavy assault rotorcraft. With its proven long-range performance, the special operations helicopter is multi-mission capable with significant combat experience, at high altitudes, in austere environments and with limited visibility. Military worldwide including the Netherlands Air Force, United Kingdom’s Royal Air Force, Egyptian Air Force, Singapore, Japan, Australia and many more currently use this Boeing platform.
This aircraft has a history of performing search, rescue and humanitarian missions around the world,. The configuration that meets the customer’s requirements is in active production and, as such, is a low risk choice for the U.S. Air Force.
The HH-47 is fully equipped and includes a net-ready cockpit, forward-looking infrared radar, terrain-following-terrain avoidance radar, and is capable of in-flight refueling. The aircraft also has a special corrosion protection for the fuselage and rescue hoist. In addition to improved power, avionics, vibration reduction and transportability enhancements, the HH-47 CSAR-X model will feature an environmentally controlled patient treatment area, a 48-inch starboard door, rotor blade de-icing and wire strike protection. The aircraft is compliant with key performance parameters, and incorporates the advanced functionality to perform demanding CSAR missions.
Utilizing today’s technology expands the range of improvements in this aircraft. The Common Avionics Architecture System cockpit makes the aircraft fully compliant with digital battlefield requirements. Adding the latest joint capability, like Link 16, furthers the dynamic flexibility of this aircraft.
The HH-47 has a fully coupled autopilot, integrated multimode radar for nap-of-the-earth and low-level flight operations in the clouds, or in extremely poor visibility conditions. Improved digital maps, greater situational awareness, mission planning and management capability enable flight crews to conduct missions with pinpoint accuracy.
This search and rescue aircraft features more powerful and efficient T-55-GA-714A engines with full authority digital electronic control. The engines each produce 4,868 maximum shaft horsepower, which enables the aircraft to reach speeds in excess of 175 mph and provides the capability to transport a payload of up to 21,016 lbs. With its internal auxiliary fuel tanks, the HH-47 CSAR -X is capable of self-deployment over 1,160 nautical miles without refueling. The new aircraft will be equipped with an improved air transportability kit, fully compliant with time requirements, to simplify aft pylon removal and cut build-up time, making strategic deployment a greater option.
This aircraft has a reputation for reliability and versatility spanning 40 years of service as a combat, multi-force aircraft. Beyond combat assault, in high altitudes and severe weather conditions, the platform is deployed wherever humanitarian needs arise. Most recently, the aircraft was widely used in the multi-national tsunami efforts for rescue, recovery, and medical evacuation and transport operations and is participating in the recovery efforts on the U.S. Gulf Coast.
