Knox Army Heliport

Home to the CH-47 Chinook

The CH-47 Chinook has been in U.S Army service since 1962 and will remain in the Army fleet at least through the 2030s. The Chinook is a tandem rotor, medium-lift helicopter that meets tactical and combat support mission requirements for military forces around the world. The Chinook is the world’s most reliable and efficient transport helicopter, capable of handling useful loads up to 24,000 pounds (10,886 kg), a maximum gross weight of up to 50,000 pounds (22,668 kg), maximum speed of 170 knots, and a service ceiling of 20,000 feet. With a crew of three, Chinook helicopters can transport 34 combat troops or 24 casualty litters. These aircraft can carry palletized cargo internally as well as its three cargo hook external load capability. The tandem rotor configuration also provides exceptional handling qualities that enable the CH-47 to operate in climatic, altitude and crosswind conditions that typically keep other helicopters from flying. The current versions of the Chinook are the CH-47D and F. The CH-47D/F fleets are the result of modernization efforts to maintain heavy lift capabilities for the U.S. Army and international defense forces. The CH-47D aircraft was rolled out in March of 1979 and reached its 20 year service life admirably with its upgraded power plants, rotor transmissions, integral lubrication and cooling, along with the improved electrical and modular hydraulic systems. This latest version, the CH-47F Improved Cargo Helicopter (ICH), contains a fully integrated, digital cockpit management system, Common Aviation Architecture Cockpit and advanced cargo-handling capabilities that complement the aircraft’s mission performance and handling characteristics. The CH-47 Chinook provides continued support, coverage and sustainment for maneuver, fire support, air defense, mobility, and survivability mission areas. The primary mission is transportation of ground forces, supplies, and battle critical cargo in support of all future contingencies. The geographical mission area for the Chinook is worldwide; anywhere aviation or ground operations are being conducted by U.S Forces. Chinooks have performed humanitarian support, disaster relief, rescue, fire-fighting, and nation-building mission on six continents in all climates and conditions. Through its speed and agility, the Chinook will meet time sensitive transportation requirements of urgently needed armed forces, equipment and supplies, that are not otherwise rapidly available from ground transportation systems. Missions will be conducted during day and night, adverse weather, and extreme environment across the range of operations from support of friendly host nations, primary regional conflicts and high intensity battle.
