CH-46 "Bull Frog"





History

The CH-46 started life as Boeing Vertol Model 107. This was a twin-rotor, twin-engine design that first flew in April 1958. Production of all variants of this aircraft ended in the early 1970s. The Japanese operate a licensed version of this aircraft designated KV-107.

The first US military version was the CH-46A (initially designated HRB-1), which entered service and began operations in Vietnam in March 1966. The early Sea Knights were capable of carrying 17-25 troops or 4000 pounds of cargo over a combat radius of 115 miles.

The CH-46E is one of the current versions of the aircraft still in service and was the primary mode of airborne transportation for the Marines during Operation Iraqi Freedom. These aircraft had been scheduled to be replaced by the V-22 Osprey, but delays in development have forced the CH-46 to soldier on into the 21st Century.
