Prior to the fall of the Soviet Union, the Air Force was divided into three aircraft based groups of units.
[1] Its design was based on An-72, with a completely redesigned rear fuselage supporting the radar dome (rotodome) atop the broad-chord forward-swept fin.
The program was cancelled with the fall of the Soviet Union when issues with the radar Vega-M Kvant could not be resolved.
The AV-MF decided to seek a second purpose-built AWACS proposal using an improved Kvant-M version of the existing An-71/An-75's Kvant Radar by the Vega-M design bureau.
In the end, the An-75 would have shared only slight commonality with the An-71/An-72 aircraft families and was deemed too costly to continue, considering the clean-sheet design of the Yak-44E.
