HTK-BS47 Polish Air Force Su-22M4 paint set
Standard colours of Polish Su-22M4 / UM3K fleet from late 1990s till 2015
In 1990s Polish AF's Su-22M4 / UM3K fleet started to undergo overhauls in WZL-2 in Bydgoszcz. In 1997 the new camouflage scheme (so-called "NATO scheme") was tested on Su-22M4 "3214" and approved for use on all overhauled Su-22s. Since that time all operational Su-22M4s and UM3Ks had been repainted using this pattern.
In 2015 a decision was made to change the already classical "NATO scheme" for a two-tone grey camouflage (similar to the one used on Polish F-16s). The change being applied during the final round of periodic overhauls in WZL-2 to all aircraft remaining in service.
