Some aerial combats
4th November 1936: the first I-15 combat. 11 Chatos led by P.V.Rychagov attacked 9 He51 and shot down 4 of them.
(It's the one of few examples when the Republicans had number superiority.
In most cases that was on the contrary, especially in the end of the war - because of huge German and Italian help to the Nationalists.)
In the same day, I-15s downed and damaged some Fiats. Soviet planes had no combat losses, but 2 pilots
mistakenly sat to an enemy airfield. The fascists killed them and cut one of them and drop his
body parts in a box to Republican positions - what a chivalry...
6th November 1936: the first air combat over Madrid. Junkerses and Fiats tried to bomb the capital again. But this time
the Republicans have Soviet fighters and shot down 9 nationalists planes.
November 1936: The big melee over 200 planes (I-15, I-16, R-5 vs He51, CR.32).
the Republican losses: 4 planes ; the Nationalist losses: 15 planes
15th May 1937: the 1st downed Messerschmitt-109, the victory of Leopoldo Morquillas Rubio.
29th May 1937: German brand-new heavy cruiser "Deutschland"
was attacked by two SB bombers (commanded by Ostryakov) which achieved two direct hits and one point-blank explosion.
There were destroyed: the 3rd 150mm turret, the one of boilers, a hydroplane; 23 men killed and 77 wounded.
14 June 1937: 14 I-15 along with I-16 engaged big group of enemy planes (Ju52/3m,
He46, He51, CR-32). Nationalists losses: 1 Junkers and 6 ftrs, Republican losses two I-15 and two I-16.
8th July 1937: the 1st Messerschmitt combat over Madrid. It was initiated
as I-15's (10 planes) combat vs bigger number of Fiats (20..30).
Three CR.32's were shot down; and one I-15 was flamed, but managed to ditch. Then 10 I-16's arrived and
8 Bf109's appeared too. In result two brand new German planes were shot down.
27th July 1937: the 1st night victory (a Junkers by Soviet pilot M.Yakushin).
1st September 1937, Belcite area: During the day Republicans managed to shot down
at least 26 (downed to Republican territory) Nationalist planes by cost of
only 2 own planes. 19 nationalist pilots were POWed, including famous Carlos Bayo.
15th October 1937: ground strike to Garapinilios. It was the preventive
and well-planed action which had great success. I.Eremenko was the flight
leader of 64 ftrs. Two I-15 sqds led by Serov and Chindosvindo attacked the airfield by MG fire and little bombs.
Four I-16 sqds led by Zarausa, Pleschenko, Devotchenko, Gusev
wasted time in close escort, then strafed some ground targets too.
Meanwhile 16 bmrs (SB-2's led by A.Senatorov) hit military targets of Saragossa.
About 60 Nationalist planes (which were almost ready to take off to hit Republican airfields) were
destroyed and damaged; AA batteries were caught at surprise and
suppressed; 2 109's were flamed when they tried to scramble; fuel tanks
and ammo storages blowed up; personnel barracks and just arrived buses
with pilots were strafed. The Republicans had no losses.
5th September 1938: Intercept (I-16 vs Bf109, CR.32, Ju86).
the Republican losses: 2 Moscas ; the Nationalist losses: 6 CR.32's + 2 Bf109's + 2 Ju86's
The best mission of the time. In 1938,
Sergey Gritsevets shot down 7 (seven!) Nationalist planes (incl. 5 Chirries)
during one half of hour. The Soviet ace flew I-16 type 10, which one was
badly damaged, but the talent pilot was able to land even in such situation.
It was the best record until famous combat of Alexander Gorovets in 1943.
18th September 1938: 1st combat of I-16's type 10 equipped with instandart F-54 engine
with improved hight-alt capabilities. In company with regular I-16's type 10
and I-15's eleven Bf109's were shot down with no Republican losses.
