Standard colours of Ukrainian aircraft in grey pixel camouflage

After
collapse of the Soviet Union the Ukrainian AF inherited a great number
of combat aircraft, including Su-27s, Mig-29s, Su-24s and Su-25s of
different age and condition. Ever since, the Ukrainian AF has been
downsizing and trying to upgrade its forces.

Although most of the
design bureaus specialized in combat planes stayed outside of Ukraine,
it retained some very experienced repair plants, capable of modernizing
the inherited inventory. Amongst the types that since 2010 have
gradually re-entered service after some kind of modernization are
MiG-29MU1, Su-25M1 (and two-seater Su-25UBM1), Su-24M, Su-24MR and
L-39M1 trainers.

Majority of the modernized airframes, but also
some only overhauled (not modernized) ones, wear a distinctive grey
pixel camouflage.
