The first Boeing F-15EX serial 20-0001 commonly known as “EX-1” completed its maiden flight on February 2, 2021 and delivered March 10, 2021. On April 20, 2021 an official ceremony was held at Eglin AFB and the new aircraft was named F-15 Eagle II. This is the most advanced version of the F-15 ever built 48 years since the first F-15A flew. The USAF hopes to purchase 76 F-15EXs over 5 years and a final total of 144. The F-15EX is ready to fight as they leave the production line.
