The Boeing CH-46 Sea Knight helicopter has served the US Navy and Marine Corps faithfully since the early 1960s. The Sea Knight was originally designated the H-49. This venerable aircraft's primary mission areas in the Navy (as the H-46D) include Combat Logistics Support and Vertical Replenishment (VERTREP), Search and Rescue, and Special Operations. As a Marine Corps platform, the H-46E is used primarily during cargo and troop transport. The unique tandem-rotor design of the Sea Knight permits increased agility and superior handling qualities in strong relative winds from all directions, allowing, in particular, rapid direction changes during low airspeed maneuvering. This capability has resulted in the safe, efficient and graceful transfer of many millions of tons of cargo and many thousands of passengers over the years.

The United States Marine Corps has been flying the CH-46 Sea knight helicopter, commonly known as the 'Phrog,' since 1962. The Phrog is a descendant of Boeing's first turbine-powered helicopter--the Boeing 107 -- which first appeared in 1958, and which is still flying various missions throughout the world. In 1961, the USMC picked the CH-46 as its new medium-lift troop transport, replacing the ageing UK-34. Over 600 Phrogs were delivered to the USMC between 1962 and 1971. By the early 1990s fewer than 250 airframes were still flying in the Corps.
