Description:
CH-46 Sea Knight was developed by Boeing to meet the US Marine Corps (USMC) requirements for a medium-lift helicopter as a replacement for the UH-34. In 1964 Boeing delivered the first two three-blade rotor CH-46A aircraft powered by two T58-GE-8 engines rated at 1,250-shp each. In 1968 H-46 production model was the CH-46D which was powered by two more powerful T58-GE-10 engines rated at 1,400-shp each.
In 1978 the USMC took delivery of the first CH-46E Sea Knight aircraft which was the result of upgrading existing D models to the new standard. The CH-46E Sea Knight was powered by two T58-GE-16 engines rated at 1,870-shp each. Currently, CH-46E is the only H-46 model operated by the USMC. The US Navy also ordered the H-46 aircraft under the UH-46 designation. The USMC CH-46A and CH-46D models were delivered to the US Navy as the UH-46A and UH-46D.
US Navy's H-46 helicopter primary mission is shipboard delivery of personnel and cargo. The USMC CH-46E Sea Knight provides all-weather, day/night assault transport of combat troops operating from the US Navy's carriers, amphibious ships and landing docks anywhere in the world. Transport of supplies and equipment is a secondary task for the USMC. H-46 is flexible enough to conduct additional missions such as search and rescue, medical evacuation, etc.
Sea Knight was sold to Sweden as the HKP-4, Saudi Arabia, Japan as the KV 107 and Canada as the CH-113. The Japanese KV 107 was produced locally under license by Kawasaki Heavy Industries till 1990.
