accentuated in the Great Patriotic War. Most
of the shattering losses in the first two weeks
were sustained not in air combat but on the

unemployed, but such was the Luftwaffe's

By the spring of 1939 the two prototypes
had been built, the first powered by a 900hp

M-63 of the same power. The third prototype,
powered by an ungeared M-63, was ready by
the autumn. The first two had a fixed under-
carriage, while the third had retractable gear.
All three had open cockpits.

11-21
Of all the many and varied duties performed
by Sergei Ilyushin's 11-2 attack aircraft during
the war, the most unusual was its operation
as a fighter. While this large Soviet attack air-
craft was inferior to the Messerschmitt Bf109
and Focke-Wulf Fw 190 in dogfights, it outper-
formed all other Luftwaffe aircraft. At the very
beginning of the war Luftwaffe front line units
equipped with the Henschel Hs 126 suffered
most of all from the ravages of Il-2s, and they
often attacked close formations of Junkers
Ju87 dive bombers, knowing that the 7.92mm
machine guns of the German aircraft were in-
effective against the Soviet armoured attack
aircraft. Once their close formations were
broken up and their concentration of fire was

fighter, or literally 'destroyer'). The 1-22 fight-
er, to which reference has been made in pre-
vious accounts, is not mentioned at all in
contemporary documents, and it can be ar-
gued that it never existed.
Design studies of the 1-301 advanced with
difficulty. Although the bureau had 93 work-
ers in December 1939, it was still disorgan-
ised. Unlike the Yakovlev OKB it had not
gained experience by producing trainers, and
it did not enjoy the support of a production
plant, like Mikoyan's OKB. Other designers
were using used new and advanced compo-
nents, but in the case ofOKB-301 the aircraft's
basic structural material was still experimen-
tal, not having been tried under normal condi-
tions for any length of time.
There were unavoidable conflicts between
the three leaders; frequently their decisions
were far from being mutually agreed. For ex-
ample, in the course of manufacturing the air-
craft, Gudkov insisted on a metal tailplane,
and other problems arose during the work.
For this reason the Administration of the Peo-
pie's Commissariat urged that one of the
three designers be appointed to take respon-
sibility. Semyon Lavochkin was chosen as
being the most competent.
Development of the aircraft was difficult.
The VIAM-B-3 adhesive used was still in the
experimental stage, and produced an un-
pleasant surprise. It contained much pheno-

not examined, and despite the efforts of ar-
mament engineer V Berezin its weapons sys-
tem was not improved. It was decided to
proceed with updating and developing the 1-
301 while simultaneously building a small
batch of 25 to 30 aircraft for operational trials.
The prototype's test report concluded:
'In terms of design, the problem of creating
an aircraft utilising re-inforced wood has
been mainly solved in the 1-301. People's
Commissariat of the Aircraft Industry Alexey
Shakhurin is requested to ask the Commis-
sariat to devote more attention to the prob-
lem of refining, testing and building the 1-301.'
Although the new fighter was obviously of
interest to the Red Army Air Force, 115 de-
fects and deficiencies, not including the ar-
mament, were detected, 14 of them being
eliminated during the tests. Among the main
faults mentioned in report were:
• the cockpit was hot,
• the canopy transparency was sub-
standard,
• the stick forces when operating the
ailerons and elevators were too great,
• longitudinal stability was inadequate,
• at the aircraft's flying weight the wheel
loads were limited, preventing normal
operation of the undercarriage.
Development work continued. An accident
occurred on 11 th August 1940, when the low
sun dazzled Nikashin during a landing and
the aircraft was seriously damaged. It was de-
cided to speed up construction of the second
example while the first prototype was re-
paired. On 2nd October 1940, as both aircraft
were about to be rolled out, the government
issued an edict that all new fighters should
have a range of 621 miles (l,OOOkm). One of
