Who's that new guy in our airspace? It's Boeing's new F-15QA designed for the Qatar Emiri Air Force. Operating out of MidAmerica Airport, formal training and instruction will be given to the pilots of this new aircraft over the next several months–ed by Scott's OSS team! pic.twitter.com/pks31DGOqo

The F-15QA is one of the latest and most modern variants of the F-15 Eagle. Designed and manufactured by Boeing for the Qatari Air Force, which acquired a total of 36 units of the aircraft – with an option for another 36 –, the F-15QA incorporates numerous advances in avionics systems and in the electronic warfare suite. The engines were also improved: the fighter uses two General Electric F110-GE-129, more powerful than the Pratt & Whitney F100 models used in the USA.
Its structure was also modified to increase its payload, being able to carry more weapons. The aircraft is still under development. Possibly was on a test flight when the incident occurred.
The model was also used as the basis for the development of the US Air Force's F-15EX Eagle II. The USAF intends to acquire up to 144 F-15EX to replace its older Legacy Series (C/D) F-15s.
