CH-46A Sea Knight
National Museum of Naval Aviation
the Navy ordered a tandem-rotor helicopter design, the HRB (later CH-46),
featuring a rear cargo-loading ramp, a top speed of 166 m.p.h., and the
ability to carry 4,000 lb. of cargo or 22 combat-equipped troops. The first
Sea Knights were delivered in June 1964, and entered combat in Vietnam
during 1966. Known affectionately as the "Phrog", the helicopter has served
the Marine Corps continuously since Vietnam. Typically, Marine Expeditionary
Units operating on board amphibious assault ships include twelve CH-46s to
transport leathernecks ashore.
