Fighter, is an adaptation lagg-3 under the air-cooled engine M-82. such modification study conducted from the end of 1940 g. In summer 1941 g. under the direction of MI. Gudkov factory number 21 (g. Bitter) Gu-82 aircraft was built, and in the early 1942 g. factory number 31, evacuated to Tbilisi – jet lag 5, designed by MP. Gorbunov. However, in a series of a third embodiment implemented lagg-3 to M-82, developed under the leadership of SA. Lavochkin.

prototype construction were at the plant №21. He first flew in March 1942 city, and already 21 April, it was signed by a generally positive conclusion on the results of state tests. 20 May came the order to launch the aircraft into series production at the factory number 21 under the designation LaGG-5, but in August 1942 g. the designation was changed to La-5. Airplane retained inherent lagg-3 tselnoderevyannaya structure. weaponry – Two 20-mm cannon synchronous SP-20. Suspension was allowed two 50-kg bombs.
Military trials La-5 took place in the second half of August 1942 g. in 49th ICAD during operation Rzhev- Sarychevskoy. For two weeks the new aircraft performed 180 sorties, knocking 16 enemy aircraft and lost 10 own. At the same time there have been numerous breakdowns and accidents La-5. In the second half of August to Stalingrad arrived 240y IAP, who lost almost all of the La-5 10 days of fighting. In a more appreciable amount of La-5 appeared at Stalingrad in December 1942 g. Here they fought 13th and 181st IAP, 3-th and 5-th GIAP.
As of 1 January 1943 g. Red Army Air Force had 717 La-5 – less 10 % fighter fleet. Since March, they have participated in the battles of Kharkov, then in the Kuban, at Leningrad and Velikie Luki. The large numbers of La-5 were used in the Battle of Kursk. 215 I'm here fighting for them, 279-I, 286-I, 295-I, 302-I, 322-Ya hoping, 3-I 8th Hyades, and also five regiments within other divisions – total, 29 regiments. In the autumn 1943 g. La-5 fought on the river. Mius and in the battle for the Dnieper. By the end of the year of this type of aircraft we were on all fronts, except the Far North, as well as the Air Force of the Baltic and Black Sea Fleets.
AT 1944 g. combat use tactics La enriched 5 due to the wider application of offensive receptions, incl. "Free hunt" and blocking enemy airfields. For "free hunting" stood out whole regiments – eg, 19-and PAI (1-Second Ukrainian Front). The blocking actions considerable progress achieved 1st Hyades VVS Baltic Fleet. Aircraft La-5 made up a significant share not only in tactical aviation, but in Fighter Corps Reserve Bids -naprimer, in the 4th and 7th IAK. spring 1944 g. the body acted in the Romanian direction. In June and July 1944 g. parts, armed with La-5, We took an active part in the offensive operation "Bagration" in Belarus. Contributed to the La-5 and break the siege of Leningrad, liberation of Karelia. But, although production of La-5FN still ongoing, in combat units to replace them began to come more advanced Yak-3, Yak-9U and La-7. Nevertheless, by the end of the Great Patriotic War, the La-5 (mainly modifications FN) More were armed 42 fighter Wing. They participated in the battles in East Prussia, Hungary, Czechoslovakia, in Berlin offensive. After the war, the mass cancellation of the La-5, but even in August 1945 g. parts (eg, 939-and PAI) We managed to take episodic part in the war with Japan. Generally, wooden La-5 design, quite appropriate in wartime, when the aircraft service life was, usually, small, not suitable for continuous operation in peacetime. In April 1946 g. It was officially decommissioned La-5 and La-5F, A year later, a similar decision was taken and La-5FN.
In addition to the USSR, La-5FN were in service in Czechoslovakia. spring 1944 g. they formed in the USSR armed 128-th separate the IAE, soon deployed in the 1st Czechoslovak IAP, received 24 La-5FN and 1 La-5UTI. During the Slovak National Uprising in September-October 1944 g. This part was based in Zvolen, in the territory, controlled by insurgents. In January 1945 g. It has been received yet 4 La-5UTI, and in April-May – 27 La-5FN. After the war, Czechoslovak La-5FN was given the designation S-95, a La-5-UTI – CS-95. With their arms lifted in the middle 1948 g.
The aircraft La-5 with all its advantages and disadvantages was the product of his era, established taking into account the difficulties of wartime, requirements of the front and mass production capabilities. By complex tactical flight characteristics La 5 well suited to the East Front conditions and made a significant contribution to the victory.
Major modifications La 5:
The total volume serial production of La-5 of all modifications made 10002 Aircraft. The lion's share accounted for the plant number 21 – 9229 machines (1107 at 1942 city, 4619 in m-1943 and 3503 in 1944). factory number 381 I passed 460 aircraft (239 at 1943 g. and 221 in 1944), № 99 -286 (184 at 1943 g. and 102 at 1944 city) and number 31 – 27 (22 at 1942 g. and 5 at 1943 city). Battle casualties 2591 car: 73 at 1942 city, 1460 in 1943, 825 to 1944-m and 233 at 1945 g. No less serious were the losses in accidents and catastrophes: only 1944 g. For these reasons, we are written off 736 samoletov.Osnovnye modification:
La-5 – motor M-82A. During the production and retreading introduced bronespinka tanks, and from October 1942 g. -bulletproof glass canopy hood. Serial production of the factory number 21 It began in August 1942 g. (initially by rework finished gliders lagg-3), December 1942 – January 1943 gg. small batch of La-5 assembled factory number 31.
La-5F – variant with the engine M-82F with an improved control system and the oil system afterburner. To facilitate machine gun ammunition with reduced 220 to 200 rounds on the barrel, fuel supply is also reduced. Later series got lower fairing and a flashlight with back review. Since December 1942 g. to build a plant number 21, then release mastered plants number 99 Ulan-Ude 381 in Moscow.
La-5FN – built in May 1943 g. M-mounted engine with direct injection 82FN. Ammunition guns reduced to 170 rounds on the barrel. In the manufacturing process we implemented numerous enhancements, chief among them the introduction of the metal wing spars (39 Series). emergency discharge lamp device also introduced, inert gas system, etc..
La-5UTI – double training fighter. Of arms left only one gun. Notable deteriorated compared with the base machine longitudinal and directional stability. A minor amount of the converted aircraft, admissions for repair.
The series is not introduced modifications La-5TK (high-altitude fighter, equipped with two turbochargers TC-3) and La to the motor M 5-71F.
