Aerial warfare in the Winter War


The aerial warfare in the Winter War was the aerial aspect of the Winter War between Finland and the Soviet Union from 30 November 1939 to 13 March 1940. While the Soviet air forces greatly outnumbered the Finnish Air Force, the Soviet bombing campaign was largely ineffective, and Finnish pilots and antiaircraft gunners inflicted significant losses on the Soviets.

Soviet Air Force

The Soviet Union enjoyed air superiority throughout the war. The Soviet Air Force, supported the Red Army's invasion with about 2,500 aircraft of the Soviet Air Forces, for the loss of only one I-16.
Finland's capital city, Helsinki, was bombed on the first day of the war; a number of buildings were destroyed and some 200 people were killed. However the city was the target of raids only a few times thereafter. All in all, Finland lost only 5 percent of its total man-hour production time due to Soviet bombings. Nevertheless, bombings affected thousands of civilians as the Soviets launched 2,075 bombing attacks on 516 localities. Air raids killed 957 Finnish civilians. The city of Viipuri, a major Soviet objective, was almost leveled by nearly 12,000 bombs. No attacks on civilian targets were mentioned in Soviet radio or newspaper reports. In January 1940, Pravda continued to stress that no civilian targets in Finland had been struck, even by accident.

Soviet aircraft

At the start of hostilities the Soviet Air Force had the following aircraft in service:
Fighters
Bombers
Reconnaissance
Naval aviation
Figures of Soviet losses during the conflict vary from source to source; One estimate puts the loss at 700-900 aircraft, the majority of them bombers: Against this Finnish losses were 62 aircraft, with a further 59 damaged beyond repair. Another states Finnish aircraft shot down 240 Soviet aircraft, with anti-aircraft fire accounting for 314 to 444 others.

Finnish Air Force

At the beginning of the war, Finland had a very small air force, with only 114 combat airplanes fit for duty. Therefore, Finnish air missions were very limited and fighter aircraft were mainly used to repel Soviet bombers. Old-fashioned and few in numbers, Finnish aircraft could not offer support to the Finnish ground troops. Therefore, the Finnish Air Force adopted the same guerilla tactics used by Finnish ground forces, dispersing to makeshift airfields often consisting only of a frozen lake. In spite of aircraft losses throughout the war, the Finnish Air Force grew by 50 percent by the end of the war. Most new aircraft shipments arrived during January 1940.
The Finnish Air Force had also revised its tactics; In air combat, the Finns used the more flexible "finger four" formation, which was superior to the Soviet tactic of three fighters flying in a Vic formation. This formation and the credo of Finnish pilots to always attack, no matter the odds, contributed to the failure of Soviet bombers to inflict substantial damage against Finnish positions and population centres.
Finnish fighter pilots often dove into Soviet formations that outnumbered them ten or even twenty times, and Soviet bomber formations became wary of even single Finnish fighters, as they knew the pilot would not let them pass un-noticed. Entire squadrons could disappear on missions over Finland, and those back at their bases in Estonia could only guess at what had happened.
On one occasion, the Finnish ace Jorma Kalevi Sarvanto encountered a formation of seven DB-3 bombers on 6 January 1940 and shot down six in just 4 minutes.

Finnish aircraft

At the start of hostilities, the Finnish Air Force had 146 aircraft of all types at its disposal, organized into 12 squadrons. The primary fighter aircraft were
There were also 18 license-built Bristol Blenheim bombers. In 1939, an order had been placed in Italy for 25 Fiat G.50 fighters; two were being assembled in Sweden when the war broke out.
During the war, a number of aircraft were ordered from abroad:
Also there was a Swedish volunteer squadron named Flight Regiment 19, Finnish Air Force taking care of the air defence of Northern Finland. It was equipped with 12 Gloster Gladiator II biplane fighters and 5 Hawker Hart biplane bombers.
Owing to this reinforcement, the Finnish Air Force had a greater strength at the end of the conflict than at the beginning; however they were seldom able to field more than 100 aircraft at any one time against an expanding VVS commitment.
Finnish fighters shot down 240 confirmed Soviet aircraft, against the Finnish loss of 26. A Finnish forward air base often consisted of only a frozen lake, a windsock, a telephone set and some tents. Air-raid warnings were given by Finnish women organized by the Lotta Svärd. Finnish antiaircraft gunners shot down between 314 and 444 Soviet aircraft.
