Donskoye (also Bryusterort or Donskoe) is an air base in Kaliningrad Oblast, Russia, located 1 km east of Donskoye (formerly Gross Dirschkeim, lith. Tirškaimis). It is a very old airfield probably dating back to World War II, nearly at Russia's most extreme western point. The facility contains 25 aircraft pads, and appears to be in a severe state of decay. Its original length was 2000 m, but only 500 m remains.
