Function: The UH-1N is a light-lift Air Force utility helicopter used for support of Department of Defense contingency plans. The helicopter has a number of uses. Its primary mission includes airlift of emergency security and disaster response forces, medical evacuation, security surveillance of off-base movements of nuclear weapons convoys and test range areas during launch conditions. It is also used for space shuttle landing support, priority maintenance dispatch support, and search and rescue operations. Other uses include airlift of missile support personnel, airborne cable inspections and distinguished visitor transport.







History: The UH-1N entered the Air Force inventory in 1970 to provide search and rescue capabilities. The missions expanded to include missile, distinguished visitor and survival school support. Some of the UH-1Fs supporting the missile wings were eventually replaced by the UH-1N due to the greater safety and capability offered by the twin engine. Manufactured by Bell Helicopter/Textron Inc., the UH-1N is the military version of the Bell 212.







Description: The UH-1N is capable of flight in instrument and nighttime conditions. The crew complement is normally two (pilot and copilot), but may be flown single-pilot depending on weather and mission requirements. The crew complement for hoist, over water and navigational operations is three, adding a flight engineer. When configured for passengers, the UH-1N can seat up to 13 people, but actual passenger loads are dependent on fuel loads and atmospheric conditions. The medical evacuation configuration can accommodate up to six litters. Without seats or litters, the cabin can carry bulky, oversized cargo. Access to the cabin is through two full-sized sliding doors, one on each side of the aircraft.
