Military actions would have begun with the surprise blow by the Soviet Air Force on the airfields of Eastern Prussia, Poland and Romania. The overall Soviet superiority in aviation would have made it possible to subject German airfields in a 250 km-deep border zone to continuous airstrikes, which would have led to a significant weakening of the enemy and would have facilitated Red Army ground forces operations. The ground forces were supposed to have two major strike directions: one striking towards Eastern Prussia and Poland and the other into Romania in the South.[15]
