The T-X program is a United States Air Force development and acquisition program for a new two-seat jet trainer to replace the Northrop T-38 Talon. On 27 September 2018, the US Air Force selected the Boeing/Saab T-X entry to become its trainer aircraft. The new aircraft was given the designation and name "T-7 Red Hawk" in September 2019. The Air Force's initial plan is to purchase 351 T-7s, and has an option to purchase up to 475.
