The Boeing-Saab T-7 Red Hawk, originally known as the Boeing T-X, is an American/Swedish advanced jet trainer produced by Boeing in partnership with Saab. It was selected on 27 September 2018 by the United States Air Force (USAF) as the winner of the T-X program to replace the Northrop T-38 Talon. The USAF's Air Education and Training Command (AETC) began developing the requirements for a replacement for the Northrop T-38 Talon as early as 2003. Originally, the replacement trainer was expected to enter service around 2020. A fatigue failure of a T-38C killed the two-person crew in 2008 and the USAF advanced the target date of initial operational capability (IOC) to 2017. In the Fiscal 2013 budget proposal, the USAF suggested delaying the initial operating capability to FY2020 with the contract award not expected before FY2016. Shrinking budgets and higher priority modernization projects pushed the IOC of the T-X program winner to "fiscal year 2023 or 2024". Although the program was left out of the FY 2014 budget entirely, the service still viewed the trainer as a priority. In cooperation with its Swedish aerospace partner, Saab, Boeing's submission to the competition was the Boeing T-X, a single-engine advanced jet trainer with a twin tail, tandem seating, and retractable tricycle landing gear. The submitted aircraft and demonstration models featured a General Electric F404 afterburning turbofan engine. Boeing revealed its aircraft to the public on 13 September 2016. The first T-X aircraft flew on 20 December 2016. On 27 September 2018, Boeing's design was officially announced as the USAF's new advanced jet trainer to replace the T-38 Talon. A total of 351 aircraft, 46 simulators, maintenance training, and support are to be supplied at a program cost of US$9.2 billion. In May 2019, Saab announced that it would open a U.S. manufacturing facility for the T-X in Indiana in partnership with Purdue University. The Royal Australian Air Force (RAAF) is looking to replace 33 BAE Hawk Mk 127 Lead-in Fighter (LIF) jet trainers, which it first ordered in 1997. Boeing intends to participate in the tender of the RAAF’s LIFT program. For details of design, avionics, operational history and variants, click here.
