The Petlyakov Pe-2 (Cyrillic: Петляков Пе-2), nicknamed Peshka (Пешка - "Pawn") was a Soviet dive bomber aircraft used during World War II. It was fast and maneuverable yet durable, and was manufactured in large numbers. Several Communist nations flew the type after the war, when it became known by the NATO reporting name Buck. The Finnish Air Force serial code was PE- and unofficial nickname Pekka-Eemeli.

[edit] Design and development
The Pe-2 was designed in a sharashka after Vladimir Petlyakov had been arrested and imprisoned in 1937 for allegedly deliberately delaying design work on the Tupolev ANT-42 bomber. In the sharashka, Petlyakov was put in charge of a team to develop a high-altitude fighter escort for the ANT-42 under the designation VI-100. The first of two prototypes flew on December 22, 1939 and was a very sophisticated aircraft for its time, featuring a pressurised cabin, all-metal construction, superchargers and many electrically-actuated systems. The prototypes proved so pleasing that production was ordered almost immediately. It is said that Petlyakov and his team could see the VI-100 prototype from their prison as it was put through its paces for the crowds watching the annual May Day parade in 1940.
Just as production was ready to begin, the air force ordered a re-design of the aircraft. The value of tactical bombing had just been displayed by the Luftwaffe in the Blitzkrieg, and the need for such an aircraft suddenly became much more important than the need for a high-altitude escort fighter. Petlyakov's team was given 45 days to redesign their aircraft as a dive bomber. The cabin pressurization and superchargers were deleted, and dive brakes and a position for a bombardier were added, among a number of aerodynamic refinements. A fuselage bomb-bay was added, along with smaller bays in each engine nacelle. Initially designated PB-100, Stalin was impressed enough with Petlyakov to free him, and his name was permitted to be used in the aircraft's designation. The first aircraft flew on December 15, 1940, rushed through production without a prototype under severe threats from Stalin if a Pe-2 did not fly by the end of the year. Deliveries to combat units began the following Spring.
While the Pe-2 generally featured favorable flying characteristics when airborne, it took a good amount of force to pull the elevators up to get the plane rotated off the runway during takeoff. Russian night bombing missions often flew with female pilots and some of the women pilots were not strong enough to get the airplane airborne by themselves. When such a situation occurred, the procedure was to have one of the crew get behind the pilot's seat and wrap her arms around the control wheel and help the pilot force the wheel back. Once the aircraft was airborne, the crew returned to her duties and the pilot continued to fly the plane without assistance.
[edit] Operational service
The aircraft did not really show its true potential until the end of the year, after the Soviet Air Force had a chance to regroup after the German onslaught during the Winter. The Pe-2 quickly proved itself to be a highly capable aircraft, capable of eluding the Luftwaffe's interceptors and allowing their crews to develop great accuracy with their bombing. Throughout 1942 the design was steadily refined and improved, in direct consultation with pilots who were actually flying them in combat. Western sources use mark Pe-2FT for production series after 83 (where FT stands for Frontovoe Trebovanie(Frontline Request)), although soviet documents do not use this identification. Final versions Pe-2K (transitional version of Pe-2I) and Pe-2I were produced in small numbers, due to unwillingness of Soviet industry to decelerate production numbers.
[edit] Finnish Air Force
In 1941, after the outbreak of Continuation War Finland purchased six war booty Pe-2 aircraft from Germany. These arrived to State Aircraft Factory facilities at Härmälä in January 1942, where the airframes were overhauled and given Finnish serial numbers. The seventh Pe-2 was bought from the Germans in January 1944, and it was flown to Finland at the end of the month.
It was initially planned to use these planes as dive bombers in the 1st flight of LeLv 48, which began to receive its aircraft in July 1942, but during the training it was found out that this caused too much strain for the engines. Thus, the role of Pe-2s was changed to fly long-range photographic and visual reconnaissance missions for the Army General Headquarters. These sorties began in late 1942, and were often flown with two 250 kg bombs for harassment bombing and in order to cover the true purpose of missions.
By the time the Soviet Fourth strategic offensive started in June 1944, the secondary bombing role had already ended and the surviving Pe-2s began to be used solely at Karelian Isthmus in escorted (normally by four FiAF Bf-109 Gs) photographic reconnaissance flights in order to find out enemy troop concentrations. These vital missions were flown successfully, allowing artillery and Finnish Air Force and Luftwaffe's Gefechtsverband Kuhlmey's bombers to make their strikes against the formations preparing for attack, which had an important effect to the outcome of the Battle of Tali-Ihantala, where the Soviet advance was halted.
During the Continuation War, three Pe-2s were lost in accidents or technical failures, one was destroyed in bombing of Lappeenranta airfield, one was shot down by Soviet fighters and one went missing in action. In the Lapland War the only remaining machine flew a single reconnaissance sortie in October 1944.
