In July 1941 Lazukin served in 4./13 IAP-KBF. This unit was at the time based at Täcktom, Hanko.

Between 21:07 and 22:00 on 22 July three I-153s of 4./13 IAP-KBF led by leytenant Lazukin flew an air reconnaissance over the Turku airfield and returned reporting “several dark spots” on the ground.
This information led to the decision to attack Turku next day.

At 14:55 on 23 July nine I-153s of 4./13 IAP-KBF led by starshiy politruk Biskup with an escort of two I-16s from 2./13 IAP-KBF (kapitan Aleksey Antonenko and leytenant Petr Brinko) took off from Täcktom airfield. The I-153s flew at low level the I-16s covered them 2000 meters high.
Over Turku airfield they encountered heavy AA barrage and the I-153 of mladishiy leytenant Mikhail Chernov was shot down in flames on the way to target and crashed into a forest. The rest of the I-153s dropped their bombs aiming on those “dark spots on the ground” and returned to base at 15:55.
On the way home Antonenko and Brinko strafed the seaplane station Ruissalo, situated not far from Turku, and claimed two He 60s destroyed on the ground.

As a revenge for the death of Chernov it was decided to attack Turku one more time during the same day.
A new group of two I-16s (Antonenko and Brinko) and two I-153s (leytenant Lazukin and mladishiy leytenant Konstantin Belorustsev) took off from Täcktom at 18:40. They attacked Ruissalo again and claimed five He 60s destroyed.
At 19:05 four Finnish Fokker D.XXIs of 2/LeLv 30 (luutnantti Martti Kalima in FR-148, vänrikki Salomaa in FR-156, Lehto in FR-152 and Järvi in FR-150) scrambled to intercept the Soviet aircraft. North of Turku they spotted a reported four I-153s and attacked. Both the I-16s and I-153s avoided the attack and headed towards Hanko. Kalima however managed to close in on one of the I-153s and claimed it damaged and presumably shot down (later upgraded to a confirmed).
50 km north of Bengtskär Island, in the vicinity of Ere Island, the Soviet fighters turned on the Finnish fighters and a fierce dogfight at 100 meters height started. The Soviet pilots returned claiming several Finnish aircraft shot down into the sea. When they returned at 19:36 they reported combat with six “Spitfires” (later changed to “Fokkers”) of which four was claimed shot down; one each by Antonenko, Brinko, Lazukin and Belorustsev.
When the landed at 19:45 the Finnish pilots reported combat with five to seven I-16s and seven I-153s of which they claimed two shot down; one I-16 and one I-153 both claimed by Kalima.
It seems that no aircraft was shot down. Kalima returned with a damaged fighter when his FR-148 had lost the antenna and suffered several hits in the fuselage and ailerons while one bullet hit was found in the fuel tank on Lazukin’s I-153.

Lazukin ended the war with 1 biplane victory.
