The Northrop T-38 Talon is a twin-engine supersonic jet trainer

. It was the world's first supersonic trainer and is also the most produced. The T-38 remains in service as of 2011 in air forces throughout the world.

United States Air Force

Northrop Corporation
Northrop Corporation was a leading United States aircraft manufacturer from its formation in 1939 until its merger with Grumman to form Northrop Grumman in 1994. The company is known for its development of the flying wing design, although only a few of these have entered service.-History:Jack...

 designs. The company began with its single-engine Northrop N-102 "Fang" concept. The N-102 was facing weight and cost growth, so the project was canceled and the company N-156 project was begun.

Although the USAF had no need for a small fighter at the time, it became interested in the trainer as a replacement for the T-33 Shooting Star
T-33 Shooting Star
The Lockheed T-33 Shooting Star is an American-built jet trainer aircraft. It was produced by Lockheed and made its first flight in 1948, piloted by Tony LeVier. The T-33 was developed from the Lockheed P-80/F-80 starting as TP-80C/TF-80C in development, then designated T-33A. It was used by the...

 it was then using in that role. The first of three prototypes (designated YT-38) flew on 10 March 1959. The type was quickly adopted and the first production examples were delivered in 1961, officially entering service on 17 March that year, complementing the T-37 primary jet trainer. When production ended in 1972, 1,187 T-38s had been built. Since its introduction, it is estimated that some 50,000 military pilots have trained on this aircraft. The USAF remains one of the few armed flying forces using dedicated supersonic final trainers, as most, such as the US Navy, use high subsonic trainers.

The T-38 is of conventional configuration, with a small, low, long-chord wing, a single vertical stabilizer, and tricycle undercarriage
Undercarriage

. The aircraft seats a student pilot and instructor in tandem, and has intakes for its two turbojet engines at the wing roots. Its nimble performance has earned it the nickname white rocket. In 1962 the T-38 set absolute time-to-climb records for 3000, 6000, 9000 and 12000 meters, beating the records for those altitudes set by the F-104 in December 1958. (The F-4 beat the T-38's records less than a month later.)

The F-5B and F (which also derive from the N-156) can be distinguished from the T-38 by the wings; the wing of the T-38 meets the fuselage straight and ends square, while the F-5 has leading edge extension

s near the wing roots and wingtip launch rails for air to air missiles. Under the paint the T-38 wing is constructed of honeycomb material while the wing of the F-5 family uses conventional skin over underlying support structure.

Most T-38s built were of the T-38A variant, but the USAF also had a small number of aircraft that had been converted for weapons training. These aircraft (designated AT-38B) had been fitted with a gunsight and could carry a gunpod, rockets, or bombs on a centerline pylon. In 2003, 562 T-38s were still operational with the USAF and are currently undergoing structural and avionics programs (T-38C) to extend their service life to 2020.

 as well as PMP (a propulsion modification to improve low-altitude engine thrust). Many USAF variants (T-38A and AT-38B) are being converted to the T-38C standard.

The fighter version of the N-156 was eventually selected for the US Military Assistance Program and produced as the F-5 Freedom Fighter. Many of these have since reverted to a weapons training role as various air forces have introduced newer types into service. The F-5G was an advanced single engine variant later renamed the F-20 Tigershark.

The AETC received T-38Cs in 2001 as part of the Avionics Upgrade Program. The T-38Cs owned by the AETC have undergone propulsion modernization which replaces major engine components to enhance reliability and maintainability, and an engine inlet/injector modification to increase available takeoff thrust. These upgrades and modifications, with the Pacer Classic program, should extend the service life of T-38s to 2020.
