Air Force chooses HH-47
The CSAR program calls for initial operational capability of the HH-47 aircraft in 2012. Under the program, which is valued at up to $10bn, Boeing will build 141 production aircraft and four test aircraft at its Rotorcraft Systems manufacturing facility in Ridley Park, Pennsylvania, which is also home to the MH-47G Special Operations and CH-47F Chinook programs.
CSAR-X is a US Air Force initiative to procure more capable and survivable aircraft able to recover isolated personnel from hostile or denied territory.
The tandem rotor, heavy-lift, high-altitude HH-47 is based on the CH/MH-47 Chinook transport helicopter, with performance capabilities that have been widely demonstrated in numerous US and international humanitarian relief operations.
