The Bell 47J Ranger is an American two-bladed, single engine, light helicopter that was manufactured by Bell Helicopter. It was an executive variant based on the highly successful Bell 47 and was the first helicopter to carry a United States president.

Design and development

The 47J was a four-seat variant of the earlier three-seat Bell 47H, the 47H was a deluxe variant of the 47G with a fully clad fuselage and enclosed cabin. The 47H proved to be too small and the 47J was developed. The "J" model was a single pilot aircraft with the pilot seat and controls position centered at the front of the cabin close to the 180° view unobstructed lexan "bubble" windscreen. A single bench seat at the rear of the cabin spanned its entire width and allowed for a passenger capacity limited by weight to typically 3 or 4 adults.

Operational history

In March 1957 two Bell 47Js were bought by the United States Air Force as presidential transport and designated H-13J. On 13 July 1957 a H-13J was the first helicopter used by a United States president when it carried Dwight D. Eisenhower from the White House. In March 1962 the two helicopters were moved from presidential duties but were used as VIP transports for the next five years until retired in July 1967.
