Boeing CH-46E Sea Knight

The twin turbine tandem-rotor CH-46 Sea Knight is a Medium-Lift Transport Helicopter. It won a design competition for a medium assault transport helicopter for the Marine Corps in 1961 and made its first flight in August 1962. The first U.S. Marine Corps Sea Knight was delivered in 1964 and began military service during the Vietnam War a year later, carrying troops and cargo to and from Navy ships in the China Sea. The CH-46 can accommodate 17 troops or 15 litters and 2 attendants with a range of 265 nm. It has a crew of 3-5. By 1968, the Sea Knight had flown 75,000 hours on 180,000 missions, including 8,700 missions rescuing wounded Marines, and had carried 500,000 troops. Between 1964 and 1990, Boeing Vertol delivered over 600 Sea Knights. The passenger version of the Sea Knight, the Model 107-II, entered service with New York Airways in July 1962. During the 1980's and 1990's, Boeing developed modification kits and upgrades to modernize the Sea Knights. The Sea Knight on display was the last CH-46 delivered to the United States Marine Corps from Boeing Vertol’s Plant 2 near Philadelphia International Airport.
