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, supercharger

 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 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 pull the wheel back. Once the aircraft was airborne, the crew member returned to her duties and the pilot continued to fly the plane without assistance.
Its armament was clearly insufficient, however. The dorsal ShKAS machine gun was inadequate. It had a high rate of fire but it also had 48 ways of jamming. The ventral Berezin UB

 had a very limited field of view and at the beginning was unreliable too. To give more protection, another ShKAS was added that could be moved between sockets on both sides of the fuselage and, in emergency, the gunner could fire upwards, but in this case he had to be quite strong to keep it in his arms. To improve the bomber's defences, a dorsal Berezin UBT

 12,7 mm was mounted. This modification was reported to increase the life expectancy of a Pe-2 from 20 sorties to 54.

Operational service

The aircraft did not show its true potential until the end of 1941, 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, able to elude the Luftwaffes interceptors and allowing their crews to develop great accuracy with their bombing.

The records of the 16th and 39th BAPs of the Western Front Air Force note that the Pe-2s crews had the greatest success in repelling the attacks of enemy fighters in June and July 1941. On 1st July, for example, six Pe-2s fended off attacks by four Messerschmitt Bf 109

, of six Pe-2s, led by Capt. A. Tsurtsulin, was a great success: 552,150 lb of petroleum were burnt in the raid. The Romanian information agency claimed tha at least 100 Soviet planes had bombed Ploesti. A German pilot shot down by a Petlyakov over Bobruysk, Maj. A. Mudin of JG 51, affirmed that the Pe-2 was the best Soviet aircraft: "It is a fast aircraft, with good armament, and it is dangerous to enemy fighters."

The Pe-2 regiments' operations were not always successful and the service pilots complained about insufficient defensive armament and survivability: there was a great risk of fire and insufficient armour protection, especially for the navigators and gunners.

German pilots soon discovered the limited sighting angles of the ventral gun mounting and its poor reliability. The ammo

 belt of the UBT machine-gun often jammed after the first burst of fire when shooting in extreme positions. The navigator and the radio operator were poorly protected.
On average, ten Pe-2 gunners were wounded for every pilot, and two or three were killed for the loss of one pilot.
Throughout 1942 the design was steadily refined and improved, in direct consultation with pilots who were actually flying them in combat. Improved armour protection and a fifth ShKAS machine-gun were installed and fuel tanks modified.
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 the unwillingness of Soviet industry to decelerate production numbers.

, 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 (551 lb) bombs for harassment bombing and in order to cover the true purpose of missions.

PE-301 and PE-215 were destroyed when Soviet aircraft bombed the Lappenranta airfield on 2 July 1944. PE-212 went down in 1943, PE-213 was destroyed in an emergency landing in 1942. PE-214 was destroyed in a failed take-off attempt at Härmälä on 21 May 1942: as Härmälä airfield was quite short, the pilot had to try to lift off with too little speed, which caused the aircraft to stall and crash, killing the crew. PE-217 managed to shoot down a Soviet fighter in 1944. PE-216 was destroyed in a forced landing in 1944. PE-211 survived the war and was removed from FAF lists in 1946. It was still standing beside the Kauhava airfield in 1952, but further information on its fate is unknown.
