With the beginning of the spring 1944 thaw, roads became impassable and temporary airfields unusable. Supplies and fuel, provided by air, allowed the Second Air Army to fly 400 sorties per day until 17 April, 1944. During this period, First Ukrainian Front consolidated its positions along the Dnieper River. Victories in White Russia and the Karelian Isthmus strained German forces. As a result, the Soviet high command ordered the First Ukrainian Front to attack Rava Ruskaya and the Lvov areas with the intention to break through and destroy German forces in the area.
The German Army Group defending First Ukrainian Front’s objectives were supported by the Fourth Air Fleet with 750 machines, while the Sixth Air Fleet provided an additional 300 to 400 machines as needed.
The reinforced Second Air Army, supporting the offensive, possessed three thousand aircraft based on 65 airfields. Planning for the assault and controlling this force required a division of labor. Twelve hundred aircraft in the Rava Ruskaya area fell under the command of Second Air Army staff under the deputy commander, General S. V. Slyusarev. This group’s mission consisted of protecting the attacking ground forces. Fifteen hundred aircraft, under the Second Air Army commander’s control with the assistance of Eighth Air Army’s field control group, operated in the Lvov area. The remaining four hundred aircraft remained in reserve.
A day or two before the beginning of the offensive, the air units moved to forward airfields. Mock airfields, constructed to distract the Germans, served their purpose admirably, drawing considerable attention from German bombers.
The offensive began on 13 July, 1944, with a two thousand plane raid intended to pin down enemy forces, suppress artillery fire, and soften up enemy strong points. Sixty percent of the Second Air Army’s assets supported mobile units. Reserves supported the armored forces. Strikes pounded the columns of German armor advancing out of Zolochev.
On 15 July the Germans attacked near Plugow forcing Soviet units to take defensive positions. Air strikes were called in to repel the attack. Soviet fighters protected the dive bombers by positioning themselves at the altitude where the dive bombing attacks began, and also at the altitude where the dive bombers recovered. Dive bombers were followed up by horizontal bombers making repeated runs. From 2 pm until 6 pm the bombings continued, augmented by the commander’s reserves. Nearly 3,300 sorties were flown. As the 8th Panzer Division advanced to the front, they too, were inundated with bombers.
By 16 July the battle neared Lvov. Bombers attacked resistance points at Vinnikov, Zhuravka, and Kratoshina, entry points to the city of Lvov. The Third Guards Tank Army circled behind the city of Lvov and coordinated its attacks from the west with those of the forces closing in from the east. Lvov fell to Soviet forces on 27 July, 1944.
From 13 July to 27 July the Second Air Army flew 30,500 sorties and destroyed 350 enemy aircraft on the ground and in the air.
