Full-scale development of the LaG-5, as the aircraft was now
designated, began, and simultaneously problems arose concerning the
initiation of the production process. Especially difficult to build
were the first ten aircraft, assembled early in June 1942, which
were manufactured in dreadful haste, with numerous errors. While it
is normal practice to make parts from drawings, this time, on the
contrary, final drawings were sometimes made from the parts. At the
same time the tooling was being prepared and the process of
producing new components was being mastered.
Aircraft Plant No.21 handled the task well. The transition to
the modified fighter was effected almost without any reduction in
the delivery rate to the air force. Following delivery of the first
fully operational LaG-5 on 20th June 1942, the Gorkii workers
turned out 37 more by the end of the month. In August the plant
surpassed the production rate of all the previous months, 148
LaGG-3s being added to 145 new LaG-5s.
Series produced aircraft were considerably inferior to the
prototype in speed, being some 24.8 to 31 mph (40 to 50km/h)
slower. On the one hand this is understandable, as the LaGG-3 M-82
prototype lacked the radio antenna, bomb carriers and leading edge
slats fitted to production aircraft. But there were other
contributory causes, particularly insufficiently tight cowlings.
Work carried out by Professor V Polinovsky with the workers of the
design bureau of Plant No.21 enabled the openings to be found and
eliminated.
Series built aircraft were sent to war, and the LaG-5's combat
performance was proved in the 49th Red Banner Fighter Air Regiment
of the 1st Air Army. In the unit's first 17 battles 16 enemy
aircraft were shot down at a cost of ten of its own, five pilots
being lost. Command believed that the heavy losses occurred because
the new aircraft had not been fully mastered and, as a consequence,
its operational qualities were not used to full advantage. Pilots
noted that, owing to the machine's high weight and insufficient
control surface balance, it made more demands upon flying technique
than the LaGG-3 and Yak-1. At the same time, however, the LaG-5 had
an advantage over fighters with liquid-cooled engines, as its
double-row radial protected its pilot from frontal attacks.
Aircraft survivability increased noticeably as a consequence. Three
fighters returned to their airfield despite pierced inlet nozzles,
exhaust pipes and rocker box covers.
The involvement of LaG-5s of the 287th Fighter Air Division,
commanded by Colonel S Danilov, Hero of the Soviet Union, in the
Battle of Stalingrad was a severe test for the aircraft. Fierce
fighting took place over the Volga, and the Luftwaffe was stronger
than ever before. The division experienced its first combats on
20th August 1942 with 57 LaG-5s, of which two-thirds were combat
capable. Four regiments of the division were to have 80 fighters on
strength, but a great many deficiencies prevented this. Serious
accidents occurred; one fighter crashed during take-off, and two
more collided while taxying owing to the pilots' poor view. During
the first three flying days the LaGs shot down eight German
fighters and three bombers. Seven were lost, including three to
'friendly' anti-aircraft fire.
Subsequently, the division pilots were more successful. There
were repeated observations of attacks against enemy bombers, of
which 57 were destroyed within a month, but the division's own
losses were severe.
Based on experience gained during combat, the pilots of the 27th
Fighter Air Regiment, 287th Fighter Air Division, concluded that
their fighters were inferior to Bf109F-4s and, especially, 'G-2s in
speed and vertical manoeuvrability. They reported: 'We have to
engage only in defensive combat actions. The enemy is superior in
altitude and, therefore, has a more favourable position from which
to attack.'
Hitherto, it has often been stated in Soviet and other
historical accounts that the La-5 (the designation assigned to the
fighter in early September 1942) had passed its service tests
during the Stalingrad battle in splendid fashion. In reality, this
advanced fighter still had to overcome some 'growing pains'.
This was proved by state tests of the La-5 Series 4 at the NII
WS during September and October 1942. At a flying weight of 7,4071b
(3,360kg) the aircraft attained a maximum speed at ground level of
316mph (509km/h) at its normal power rating, 332.4mph (535 km/h) at
its augmented rating and 360.4mph (580km/h) at the service ceiling
of 20,500ft (6,250m) The Soviet-made M-82 family of engines -
derived from the US-designed Wright R-1820 Cyclone - had an
augmented power rating only at the first supercharger speed). The
aircraft climbed to 16,400ft (5,000m) in 6.0 minutes at normal
power rating and in 5.7 minutes with augmentation. Its armament was
similar to that of the prototype. Horizontal manoeuvrability was
slightly improved, but in the vertical plane it was decreased. Many
defects in design and manufacture had not been corrected.
In combat Soviet pilots flew the La-5 with the canopy open, the
cowling side flaps fully open and the tailwheel down, and this
reduced its speed by another 18.6 to 24.8mph (30 to 40km/h). As a
result, on 25th September 1942 the State Defence Committee issued
an edict requiring that the La-5 be lightened, and that its
performance and operational characteristics be improved.
The industry produced 1,129 La-5s during the second half of
1942, and these saw use during the counter attack by Soviet troops
near Stalingrad. Of 289 La-5s in service with fighter aviation, the
majority, 180 aircraft, were assigned to the forces of the Supreme
Command Headquarters Reserve. The Soviet Command was preparing for
a general winter offensive, and was building up reserves to place
in support. One of these strong formations became the 2nd Mixed Air
Corps under Hero of the Soviet Union Major-General I Yeryomenko,
the two fighter divisions of which had five regiments (the 13th,
181st, 239th, 437th and 3rd Guards) equipped with the improved
La-5. The new aircraft proved to be 11 to 12.4mph (18 to 20km/h)
faster than the fighter which had passed the state tests at the NII
WS in September and October 1942.
When the 2nd Mixed Air Corps, with more than 300 first class
combat aircraft, was used to reinforce the 8th Air Army, the latter
had only 160 serviceable aircraft. The 2nd Mixed Air Corps,
reliably protecting and supporting the counter offensive by troops
along the lines of advance, flew over 8,000 missions and shot down
353 enemy aircraft from 19th November 1942 to 2nd February
1943.
Progress made in combat activities by the Air Corps aviators in
co-operation with joint forces during offensive operations on the
Stalingrad and Southern fronts were noted by the ground forces
Command. General Rodion Malinovsky, Commander of the 2nd Guards
Army (later Defence Minister), wrote:
'The active warfare of the fighter units of the 2nd Mixed Air
Corps [of which 80% of its aircraft were La-5s], by covering and
supporting combat formations of Army troops, actually helped to
protect the army from enemy air attacks. Pilots displayed courage,
heroism and valour in the battlefield. With appearance of the Air
Corps fighters the hostile aircraft avoided battle.
