context_page_description: The Boeing Skyfox is an American twin-engined jet trainer aircraft, a highly upgraded development of the Lockheed T-33. It was designed as a primary trainer to compete with and replace the Cessna T-37 Tweet. Besides its primary role as a trainer, the aircraft was envisioned to have other roles as well, including ground attack. The program was started by the Skyfox Corporation in 1983, and was acquired by Boeing in 1986.
  The program included the replacement of the Allison J33-A-35 turbojet by two Garrett TFE731-3A turbofans. It also included an extensive redesign of the airframe. Only one prototype aircraft was built, and the program was later canceled due to lack of customers.
context_section_description: The Skyfox was designed to be produced entirely from kits of components. The conversion involved the disassembly, the inspection, and the refurbishment of the T-33 airframe as necessary; the installation of the kits; and reassembly of the airframe in the Skyfox configuration.
  There were two conversion options: to purchase a complete Skyfox from Boeing or to purchase a conversion kit from Boeing and perform the conversion in the country itself.
  The standard conversion kit included:
  Two Garrett TFE371-3A turbofans, the nacelles, and the propulsion support system.
  Nose and tail assemblies.
  Single-point refuelling.
  Aerodynamic refinement kit.
  Structural refinement kit.
  Nose wheel steering.
  Anti-skid power brakes.
  Single-piece windscreen.
  Hydraulic components kit.
  Generator control and distribution system.
  Throttle quadrants and control system.
  Fire extinguishing system.
  Control panels for the cockpit.
  In addition to the standard conversion kit described above, Boeing also offered a number of options that could further improve the overall capability of the Skyfox:
  Avionics upgrade.
  Basic rewiring of the aircraft.
  Tactical, reconnaissance, and electronic warfare training mission packages.
  Zero-zero ejection seats.
