The T-38 can be traced back to 1952 and Northrop's N-102 Fang and N-156 fighter aircraft projects. During the mid-1950s, Northrop officials decided to adapt the N-156 to suit a recently issued general operating requirement by the United States Air Force (USAF) for a supersonic trainer to replace the Lockheed T-33. The bid was successful, in no small part on its lower lifecycle cost comparisons to competing aircraft, and the company received an initial order to build three prototypes. The first of these, designated YT-38, made its maiden flight on 10 April 1959. The T-38 was introduced to USAF service on 17 March 1961.

The USAF is the largest operator of the T-38. Additional operators of the T-38 include NASA and the United States Navy. U.S. Naval Test Pilot School in Patuxent River, Maryland, is the principal US Navy operator. Other T-38s were previously used by the US Navy for dissimilar air combat training until replaced by the similar Northrop F-5 Tiger II. Pilots of other NATO nations have commonly flown the T-38 during joint training programs with American pilots.[1] The T-38 remains in service as of 2023 with several air forces. As of 2023, the T-38 has been in service for over 60 years with the USAF, its original operator. In September 2018, USAF announced the replacement of the Talon by the Boeing–Saab T-7 Red Hawk with phaseout to begin in 2023.[2][needs update]

In 1952, Northrop began work on a fighter project, the N-102 Fang, with shoulder-mounted delta wing and a single engine.[3] The proposed General Electric J79 engine, weighing nearly two tons, meant the resulting aircraft would be large and expensive.[4][5] During 1953, representatives from General Electric Aviation's newly created Small Aircraft Engine Department showed Northrop a relatively compact engine, around 400 lb installed weight, capable of 2,500 lb of thrust. Upon seeing the engine, Northrop VP-Engineering Edgar Schmued saw the possibility of reversing the trend toward the large fighters.[5]

Schmued and chief engineer Welko Gasich decided on a small, twin-engined "hot-rod" fighter, the N-156. Northrop launched its N-156 project in 1954, aiming for a small, supersonic fighter jet capable of operating from the US Navy's escort carriers.[5] When the Navy chose not to pursue equipping its fleets in such a fashion, favoring large fleet carriers instead, Northrop opted to continue work on the N-156 using in-house funding. It was instead recast as a lightweight fighter, referred to as the N-156F, that was primarily aimed at the export market.[5]

In the mid-1950s, the USAF issued a general operating requirement for a supersonic trainer, seeking to retire its 1940s-era Lockheed T-33s for an aircraft better suited to training pilots to fly its high speed fighter aircraft.[5] Northrop officials decided to adapt the N-156 to this competition. The only other candidate was the two-seat version of the North American F-100 Super Sabre. Although the F-100 was not considered the ideal candidate for a training aircraft (it is not capable of recovering from a spin),[6] NAA was still considered the favorite in the competition due to that company's favored-contractor status with the USAF, but Northrop officials presented lifecycle cost comparisons that proved to be highly persuasive amongst USAF officials.[7] Accordingly, Northrop was awarded an initial contract in June 1956 to produce three prototypes, designated YT-38.[7]

On 10 April 1959, the first YT-38 performed its maiden flight at the hands of test pilot Lew Nelson.[7][8]

The type was quickly adopted. The first production examples were delivered in 1961, entering service on 17 March 1961, complementing the Cessna T-37 Tweet primary jet trainer. When production ended in 1972, 1,187 T-38s had been built, plus two N-156T prototypes. Since its introduction, an estimated 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.[9]

During 1962, the T-38 set absolute time-to-climb records for 3,000, 6,000, 9,000, and 12,000 meters, beating the records for those altitudes set by the F-104 in December 1958. The F-4 Phantom beat the T-38's records less than a month later.

The majority of T-38s built were of the T-38A variant. The USAF had a small number of aircraft converted for weapons training, designated AT-38B, which were fitted with a gunsight and could carry a gun pod, rockets, or bombs on a centerline pylon. By the end of September 2017, 503 T-38s were still operational with the USAF,[10] while many more remained in operation around the world.

Most of the USAF's aircraft, T-38A and AT-38B, have been converted to the T-38C through an avionics upgrade program. Improvements include the addition of a head-up display, global satellite positioning, inertial navigation system, and traffic collision avoidance system. Most aircraft have received a propulsion modification to improve low-altitude engine thrust. Around a third of the fleet, those that experience more severe usage, are currently undergoing structural replacements and upgrades, as well as receiving new wings, to extend their service life to 2029.[11]

The fighter version of the N-156 was 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-engined variant later renamed the F-20 Tigershark. In 2018, the Iranian Air Force announced that an outwardly similar aircraft, named the Kowsar, had been constructed within Iran.[12][13][14]

Design

edit

The Northrop T-38 Talon is of a conventional configuration, with a small, low-mounted, long-chord wing, a single vertical stabilizer, and tricycle undercarriage. The cockpit accommodates a student pilot and instructor in a tandem seating arrangement. The flight controls were hydraulically-powered and lacked manual reversion, and thus the aircraft would be unflyable in the event of both engines failing mid-flight.[7]

Its handling was relatively conventional and viceless. While it was originally considered to be too easy to fly compared with frontline fighters of the 1960s, by the twenty-first century, it had become regarded as the most challenging aircraft in the USAF's inventory.[15] The aircraft's nimble performance earned it the nickname "white rocket". It had been considered by trainee pilots to be a somewhat unforgiving aircraft from an aerodynamic standpoint.[16]

The T-38 can be visually distinguished from both the F-5B and F-5F, which are also derived from the N-156, by the wings. The wing of the T-38 meets the fuselage straight and ends square, while the F-5 has leading edge extensions near the wing roots and wingtip launch rails for air-to-air missiles. The wings of both the T-38 and the F-5 family use conventional skin over spar-rib structure.[17] The T-38's wings were originally designed to withstand 7.33-G loads and for a fatigue life of 4,000 flight hours. This proved sufficient for the majority of the training syllabus, but was a major limiting factor when the aircraft was used for aggressive dogfighting-style maneuvering. Incidents of wing tips separating mid-flight were reported. Northrop resolved this via the installation of new wings with thickened skins.[11]

Throughout the development process, a strict weight control regime was exercised by the design team.[7] This was one reason for the T-38's relative simplicity; only basic systems for navigation and communication were provided. No fuel was housed within the wings while no provision for external stores was made.[7] The aircraft's twin General Electric J85-5A turbojet engines were accommodated within the fuselage to exert less drag and produce fewer aerodynamic disturbances. The J85-5A engine, despite generating up to 3,850 lb of static thrust, was relatively compact and lightweight for the era, weighing less than 600 pounds.[5] Air was supplied to the engines via intakes at the wing roots. A twin-engine arrangement had been pursued to provide a greater margin of safety.[7]

Various design decisions were taken and features were incorporated to simplify the T-38 and make it as easy to maintain as possible.[7] To avoid removing the vertical fin while changing an engine, the fin was attached directly to the keel structure between the engines, and instead detaching the horizontal stabilizer along with the entire aft shell of the fuselage that surrounds the engines, which could be removed relatively easily via undoing several fasteners that hold the fuselage shell together and disconnecting two push rods that connect the pilot's control stick to the horizontal stabilizer's hydraulic actuators.[7]

To avoid having to break and reconnect multiple hydraulic lines during an engine swap, designers mounted the hydraulic pump and other accessory drives on the fuselage which joined to the engine by a short driveshaft. Several internal check valves prevented a loss of hydraulic fluid.[7] The engines hung from rails on either side of the central keel. This design enabled ground crews to remove and replace an engine in roughly one hour.[7]

Operational history

edit

Military

edit

The USAF Strategic Air Command (SAC) had T-38s in service from 1978 until SAC's 1991 inactivation. These aircraft were used to enhance the career development of bomber and tanker copilots through the Accelerated Copilot Enrichment Program. They were later used as proficiency aircraft for all B-52, B-1, Lockheed SR-71, U-2, Boeing KC-135, and KC-10 pilots. SAC's successors, the Air Combat Command (ACC) and the Air Force Global Strike Command (AFGSC) retain T-38s as proficiency aircraft for U-2 pilots and B-2 pilots, respectively.[9]

The Air Training Command's successor, the Air Education and Training Command (AETC), uses the T-38C to prepare pilots for the F-15C Eagle and F-15E Strike Eagle, the F-16 Fighting Falcon, B-52 Stratofortress, B-1B Lancer, B-2 Spirit, A-10 Thunderbolt, F-22 Raptor, and F-35 Lightning II. 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.[9] These upgrades and modifications, with the Pacer Classic program, were to extend the service life of T-38s past 2020. The T-38 has an availability goal of 75%, which it maintained in 2011. In 2015, its availability was 60%.[18]

After graduating from basic flying on the Cessna T-37 Tweet, pilots were trained on more advanced aspects, including supersonic flight, blind flying, formation flight, handling stalls, single-engine flight procedures, low speed flight, and landing techniques.[16] Prior to the USAF ceasing the practice of trainees flying within icy conditions, the T-38's engines were prone to being damaged by ingesting ice. The relatively small engine intakes are also known to be problematic when flown at low speeds under 'hot and high' conditions.[19]

The landing gear's brakes have been criticised for being relatively weak, one of several factors that necessitates care while landing. Several incidents, including fatalities, have occurred due to imprecise management of the throttles and air speed during landing attempts.[19] Despite these factors, the T-38 has been regarded as a relatively safe trainer aircraft even into the twenty-first century. Between 1961 and 2005, the fleet has cumulatively flown 25 million hours, during which 150 of the 1,187 T-38s built between 1961 and 1972 were recorded as lost, resulting in 45 deaths.[11]

Besides the USAF and the USN, other military operators of the T-38 have included the German Air Force, the Portuguese Air Force, the Republic of China Air Force, and the Turkish Air Force.[9]

During late 2010, the USAF launched the T-X program to procure a replacement for its T-38s.[20] Bidders included a joint venture of BAE Systems and Rolls-Royce, offering the Hawk trainer, equipped with Rolls' Adour Mk951 engine with FADEC. Lockheed Martin and Korea Aerospace Industries, offered the T-50. Raytheon and Alenia Aermacchi offered the T-100, an aircraft whose design originated with the M-346.[21]

Boeing and Saab offered a new-technology design powered by the General Electric F404 turbofan engine. The Boeing/Saab bid first flew in December 2016. It was declared the winner of the T-X competition in September 2018.[22]

NASA

edit

NASA operates a fleet of 32 T-38 trainers.[23] The fleet is typically used to train its astronauts and as a chase plane. NASA's fleet is housed primarily at Ellington Field in Houston, Texas. NASA's internal projections showed the number of operational jet trainers falling to 16 by 2015. The agency spends $25–30 million annually to fly and maintain the T-38s.[24]

In 1966, two Project Gemini astronauts, Elliot See and Charles Bassett, died when their T-38 hit the roof of a McDonnell Douglas fabrication building at Lambert Field in St. Louis. Visibility was poor, but a later investigation concluded that the cause of the crash was likely pilot error.[25]

During the Space Shuttle era, an established NASA tradition was for astronauts to arrive at the Kennedy Space Center in T-38 Talons.[26]

Civil

edit

Seven privately owned T-38s are in the U.S.[23] Boeing owns two T-38s, which are used as chase planes.[23] Thornton Corporation owns two T-38s, and the National Test Pilot School owns one T-38.[23] Two others are in private ownership.[23]

  88. ^ Even though this value has been printed in USAF outlets for many years, it is probably incorrect. The T-38 time-to-climb record, set in 1962, was three minutes to 30,000 feet. According to Northrop's Roy Martin (quoted on p. 64 of Air & Space/Smithsonian, Vol. 20, No. 3 (August/September 2005)), a normal climb at military power – that is, maximum power without afterburner – is around 6,000 feet/minute.
