Ivan Fedorov was born in 1916.

He graduated from Chkalovskaya Flight School in 1938.

Starshiy leitenant Fedorov took part in the Soviet-Finnish Winter War where he served in 68 IAP between February and March 1940. This regiment was equipped with Polikarpov I-153s.

In the early morning on 29 February 1940, mladshiy leitenant Viktor Masich of 68 IAP led a three-aircraft group making a reconnaissance mission to the Antrea area. Here they detected the well-camouflaged ice base at Ruokolahti. Over the Finnish air base, Masich claimed one Gladiator and he was able to return with some 80 holes in his fighter. The Gladiator lost was GL-269 of LLv 26, subordinate to LLv 24 (detachment Luukkanen), which was lost due to enemy fighter fire when it returned to Ruokolahti base after a morning alarm mission. The Gladiators had been on an abortive mission together with detachment Luukkanen’s Fokkers and were following in the wake of the Fokkers when a lone Russian I-153 appeared like a wraith and shot down the Gladiator in flames, and was gone as suddenly as it had arrived. The pilot alikersantti Pentti Kosola died of wounds.
At 12:00, the detachment received a message that 21 enemy bombers were heading towards Antrea from the south at an altitude of 16,500 feet. The detachments leader kapteeni Eino Luukkanen was prevented to take off due to a loose starboard ski on his Fokker D.XXI and command was given by him to luutnantti Tatu Huhanantti (6 victories). However, it seems that the control centre had given them wrong information or been referring to an entirely different formation for when the 14 Fokkers and Gladiators of LLv 24 and LLv 26 were climbing out of Ruokolahti field they were trapped in a most unfavourable position when they were attacked by an estimated 40 I-153 and I-16 fighters.
In fact, they were 17 I-16s and six I-153s from 68 IAP, which were returning after the morning’s reconnaissance mission. Twelve fighters were led by major Yakov Gil (I-16) while the remaining eleven fighters were led by Starshiy leitenant D. P. Yefimov (CO of 1 Eskadrilya). In the vicious battle that followed three Gladiators were shot down immediately on take-off. In the low-level combat that followed, the Russians destroyed two more Gladiators and one Fokker. The battle lasted only some fifteen minutes before the Russians withdrew.
Alikersantti Sulo Suikkanen (GL-256) succeeded in shooting down one I-16 over Kaukopää at 12:20. Suikkanen also claimed a second I-16 damaged over Imatra at the same time. A third reportedly I-16 hit the trees and crashed. Seven more Soviet fighters were damaged. During the combat luutnantti Tatu Huhanantti (Fokker D.XXI FR-94) was killed together with luutnanttis Aimo Halme (GL-262) and Carl Kristensen (GL-259). Luutnantti Poul Christensen (GL-261) and vääpeli Olavi Lilja (GL-268) parachuted to safety but both were injured and Christensen was burnt in his face and hospitalized for the rest of the Winter War. Vääpeli Jussi Tolkki (GL-263) had a remarkable escape by falling into a snow bank when his fighter disintegrated just above the trees.
The returning Soviet pilots claimed eleven “Bulldogs” and eight Fokker D.XXIs (one additional claim for an enemy fighter with an unknown pilot). Major Gil claimed one Fokker in a head on attack. The enemy fighter caught fire, overturned and came down. Gil’s second claim was a Bulldog, which got on the tail of leitenant Aleksandr Polukhin (I-16). This Bulldog also caught fire and went to the ground. Starshiy leitenant Vladimir Plotnikov (I-16) attacked a Bulldog, which got on major Gil’s tail. The Bulldog began to smoke, lost control and crashed to the ground. Starshiy leitenant Ivanov attacked and shot down one Bulldog, which got on starshiy leitenant Plotnikov’s tail. The Bulldog smoked heavily and went to the ground. Leitenants Pavel Sorokin (I-16) and Nikitin (I-16) attacked a Fokker, which caught fire and fell out of control from an altitude of 3200 metres. Starshiy leitenant Dmitriy Yefimov (I-16), leitenant Shishov, leitenant Terpugov, leitenant Viktor Orlov (I-16) and leitenant Aleksey Sapozhnikov (I-16) together claimed a Bulldog, which caught fire and crashed to the ground from an altitude of 70-100 metres. Leitenant Shishov then saw one Bulldog flying at 100 metres altitude, attacked it at high speed, overtook it, then turned back and attacked it again. The Bulldog began to smoke and crashed to the ground. Leitenant Orlov dived on the tail of a Bulldog that flew just over the ground and with fire forced it to crash to the ground. Leitenant Polukhin and mladshiy leitenant Ivan Mazurenko (I-16) saw a Fokker, which attempted to attack their flight. With a swift turn they got onto the enemy’s tail and shot it down with an attack from two sides. The enemy caught fire and crashed to the ground. Mladshiy leitenant Mazurenko then saw a Fokker got behind his tail. With a heavy slideslip, he turned his aircraft 45-50 degrees and the Fokker overtook him. Mazurenko turned back and with a long burst downed the enemy. The Fokker caught fire and crashed to the ground. Mazurenko’s aircraft returned with 36 bullet holes. Leitenant Aleksandr Platonov pursued one Bulldog and with an attack from behind, he forced it to dive. Platonov followed it and continued to fire until the Bulldog got into a spin and crashed into the ground. After the attack of the airfield, leitenant Viktor Popov was climbing for altitude when he saw a Bulldog chased by I-16s and I-153s. With a spilt-S, the Bulldog evaded their attack but Popov attacked it when it was recovering from its dive. Popov fired on it and it caught fire. While climbing for altitude, leitenant Sergey Mayev (I-16) saw a Fokker, which got behind an I-16 and began to fire. Mayev attacked the Fokker from behind and set it on fire. The Fokker crashed to ground out of control. Mladshiy leitenant Vasiliy Soldatov dropped bombs on the enemy aircraft parked on the frozen lake. After that he was attacked by two Fokkers, bus using the manoeuvrability and climbing performance of his I-153, he evaded the attack and climbed to the Soviet group. He saw that one Fokker was pursuing an I-16 and decided to attack it. The enemy decided to outrun him, but Soldatov manoeuvred behind it and fired several long bursts. The enemy aircraft went into a dive. Soldatov followed it and observed that the Fokker crashed into the forest. Leitenant Konyukhov shot down one Fokker in a head on attack. For some reason the enemy aircraft didn’t return fire. The Fokker began to smoke and hit the ground out of control. Leitenant Nikitin twice attacked a Bulldog and shot it down. It fell into the forest and caught fire. Having approached the target, starshiy leitenant Fedorov, saw one Bulldog at 2200 meters altitude. Fedorov got behind it and with two bursts shot it down. The Bulldog dived vertically and fell north of Salvisaari Island. After that, Fedorov dropped the bombs on one Fokker, which was taxiing on the lake. Just after taking off, this Fokker caught fire and hit the ice.
68 IAP lost one I-16 flown by starshiy leitenant Yefimov (CO of 1 Eskadrilya), who was killed when his I-16 didn’t level out from a steep dive to evade chasing enemy Finnish fighters, but crashed to the ground and one I-153 (c/n 521) were the pilot, mladshiy leitenant Mikhail Ivanovich Volosevich (2 Eskadrilya), parachuted at Tainiokoski to become a PoW.
This combat was the biggest single aerial defeat suffered by the Finns during the whole course of the Second World War.

When Germany invaded the Soviet Union on 22 June 1941, starshiy leitenant Fedorov served in 84-A IAP. This regiment was equipped with Polikarpov I-153s.

Starshiy leitenant Fedorov was killed in air combat on 12 April 1943.

At the time of his death, Fedorov was credited with 2 biplane victories.
These had been claimed during 208 combat missions and 48 air combats.
