Fictional story
The Grigoriev Gr-214 (NATO reporting name Empyrean) is a four-engined aerial refueling tanker
designed by the Grigoriev design bureau in the Soviet (Re)Union.
The aircraft has two removable fuselage tanks that can hold a maximum transferable load of 85.72 tonnes (188,540 lb)
All tests on the Gr-214 were succesfully performed in March 2018 and made it's maiden flight on April 10th 2018.
The Soviet airforce already owns 20 aircraft and will probably order more if the Gr-214 performs to it's expectations.
China also showed interests and will order 5 aircraft for testing and training purposes
An AWACS and Ground Attack variant are considered.
