caption_attribution_description: English: Cessna Model 407 proposal for a business jet version of the T-37 trainer.
context_page_description: The Cessna T-37 Tweet is a small, economical twin-engined jet trainer type which flew for decades as a primary trainer for the United States Air Force and in the air forces of several other nations. The T-37C was additionally capable of some light attack duties if required. The A-37 Dragonfly variant served in the light attack role during the Vietnam War and continues to serve in the air forces of several South American nations.
  The T-37 served as the U.S. Air Force's primary pilot training vehicle for over 52 years after its first flight. After completing Primary in the Tweet, students moved on to other advanced Air Force, Navy, Marine Corps or Allied trainers. With a total of 1,269 Cessna T-37s built, the USAF retired its last T-37 in 2009.
context_section_description: Cessna proposed a number of innovative variants of the Tweet that never went into production. In 1959, Cessna built a prototype of a light jet transport version of the T-37, designated the Cessna Model 407, which was stretched 2 ft (61 cm) to accommodate a four-place pressurized cockpit with an automobile-type configuration. Only a wooden mockup of the Model 407 was constructed. The project was cancelled due to insufficient customer interest.
  The company also proposed a similar four-place military light transport, the Model 405, with a big, clamshell canopy, but it was never built.
  In response to a United States Navy "Tandem Navy Trainer" (TNT) requirement, Cessna proposed a T-37 with a modified fuselage featuring a tandem cockpit. The Navy selected the North American T-2 Buckeye, instead.
  Cessna proposed various other trainer derivatives for the US Navy and Air Force, including a vertical takeoff version based on the TNT configuration and incorporating lift-jet pods in the wings, but none of them reached the prototype stage.
