Tests directly at the front confirmed the great survivability and the absolute need to re-equip all Pe-2 (Pe-3) aircraft in front-line conditions. The weight turned out to be correct and well thought out.
The first good news came from the front, letters of gratitude to the plant and categorical demands for the speedy re-equipment of the entire fleet of combat aircraft. The first combat tests were on May 5, 1942 near Kerch. Factory installations "FT" was tested by the 30th bomber regiment under the command of Colonel Nikolaev. Their appearance was a complete surprise for the Germans. When our planes, after completing a combat mission, returned to base, they were intercepted by German fighters. Confident in their impunity, they, as before, approaching from the tail, tried to get closer to 300 meters in order to beat for sure.
Several FT installations opened fire almost simultaneously, and 3 fascist fighters, engulfed in flames, collapsed to the ground. Not realizing what happened, the other "Messers" routinely repeated the maneuver and were also shot down. It was a victory for the new weapon. Meanwhile, Moscow, more precisely the 10th Main Directorate of the NKAP, represented by the head of department B. N. Tarasevich, “bombed” the plant with telegrams about the immediate removal of the “FT” installation from mass production.
A difficult situation has arisen: on the one hand, the front, its categorical demands, the complete refusal of the Air Force crews to accept Pe-2 aircraft with the ShKAS installation, and on the other hand, the leadership categorically demanded an end to "amateur activities" and bringing the perpetrators to trial by a military tribunal.
Turning to V. A. Okulov with the question “what to do?”, I heard the calm answer of Vasily Andreevich:
- Send all the leadership away, work calmly!
Finally, in complete despair, hungry and angry, I met one employee of the NKAP in the corridor, unfortunately, my memory did not retain her last name. She asked me about my affairs and promised to help. Apparently she had connections. After a while, they gave me the telephone number of Fedotikov, an employee of the Central Committee, and suggested that I call him.
After listening to me, Fedotikov asked me to call back the next day at 11.00. At the appointed time, I went to the reception of the Central Committee.
To my great joy, Fedotikov said that the issue was resolved. A decision was made to launch the FT plant in Kazan and at the Savelovsky plant.
Forgetting all the troubles, having issued a business trip, I returned with a victory to Kazan.
After some time, P. A. Chugunov, already from OKO, was sent to Savelovo to assist the plant in the implementation of the FT installation. 1010 such installations were produced at the Savelovsky Machine-Building Plant.
So the front received the necessary re-equipment of the Pe-2 aircraft.
Department of operation and repair of the plant named after. S. P. Gorbunova (NKAP USSR) in June 1942 issued the “Information Bulletin” No. 11 - 12 “Replacing the upper rifle mount for the ShKAS machine gun in the navigator’s cockpit with the FT mount for the Berezin machine gun” (repair method).
The bulletin says:
“In order to further improve the combat qualities of the Pe-2 aircraft, the plant has begun production of new FT shooting mounts. "FT" - front-line requirement - this is the factory name of the upper installation for the Berezin machine gun - UBT, designed by Comrade Selyakov and Chugunov, designers of the Experimental Design Department of the plant.
Instead of the upper firing point for the ShKAS machine gun on aircraft in units, the “FT” installation is mounted for the Berezin machine gun - UBT ... "
Pe-2 «I»
In the spring of 1944, we tested a new English bomber DH "Mosquito". This aircraft, having high speed and not having any defensive weapons, carried out raids on the rear of Germany with virtually impunity. V. M. Myasishchev called me and offered to work out a possible modification of the production Pe-2 aircraft with the aim of making it the Soviet Mosquito. Without thinking twice, I got to work.
As a result, an aircraft project appeared, which was supposed to reach a speed of 100 - 120 km / h more than the serial Pe-2.
In addition to obtaining high flight data, we were faced with the task of placing an aerial bomb of the FAB-1000 caliber on the aircraft, for which we had to create a cargo compartment, since the external suspension of bombs on a production aircraft significantly reduced its flight data, reducing speed, flight range and altitude. It was a difficult task. The Pe-2 aircraft is a low-wing aircraft, and it is impossible to place a compartment for a 1000-kg bomb without touching the center section.
To solve the problem, part of the lower steel belts of the spars of the center section was cut out and replaced with arched forged liners. The height of the wing spar along the axis of the aircraft decreased exactly by half. Then the fuselage was built up, changing the circular section in its lower part to an oval one.
The FAB-1000 bomb was placed in the resulting space.
Refinement of the spars, an increase in the midsection and fuselage surface led to some increase in the empty weight of the aircraft, but a significant improvement in aerodynamics more than compensated for this. A small gain in weight was given by the elimination of small cargo compartments for FAB-100 bombs in engine nacelles.
As a result of improvements to the aircraft, its tactical capabilities have significantly increased.
In order to achieve a decision on the creation of the Soviet "Mosquito", V. M. Myasishchev went to Moscow. I had to, without waiting for a decision, to deploy design work.
Soon the decision of the Government was received.
The aircraft, which received the Pe-2 "I" index, had no equal in terms of its speed characteristics.
During training air battles during state tests, it was shown that modern fighters Me 109, FV190 and our Yak-3 cannot intercept and attack it: the flight speed is too high. It differed from the production Pe-2 aircraft in the best contours of the forward fuselage, all radiators were removed into the wing with air outlet under the wing, and not on its upper surface. The wing tips, as on the latest production models, were blunted with a NASA 23012 profile, which improved stall characteristics at high angles of attack. The engines were VK-107 with a capacity of 1650 hp from each.
In the tail section of the fuselage, a remote shooting mount was installed under the Berezin machine gun cal. 12.7 mm, from which the navigator fired. Crew - 2 people.
The aircraft successfully passed state tests and was recommended for mass production. At the very end of the war, a small series was built.
Factory flight tests of the Pe-2 "I" - "Mosquito" aircraft were carried out by test pilot A. G. Vasilchenko.
During the creation of this aircraft, the aerodynamics group was led by Emmanuil Anatolyevich Osherov, a competent, very good and likeable person, but very cautious.
We had an interesting technical dispute with him. Having carried out all the necessary calculations, Osherov stated that the maximum flight speed could be obtained until 620 km / h, with a given one - 640.
I told him that he was being careful and making mistakes, and we would complete the task, but he firmly stood his ground - 620 and no more.
Flight tests showed - 656km / h!
Thus, the Pe-2 "I" became the fastest Soviet bomber during the Great Patriotic War. Unfortunately, he arrived too late.

Our plane would still have engines like the Mosquito, and not with our resource ...
