The LaGG-3 was designed by Soviet engineers Lavochkin, Gorbunov, and Gudkov to replace the LaGG-1. The original LaGG-3 prototype was made almost entirely out of wood. The airframe was made out of special multi-ply wood bonded with resin. The wings were similar to that of the Yak-1, the difference being the LaGG wing was made in two sections. The fuselage was similar to another Russian fighter, the MiG-3. Armament includes a 20 mm ShVAK rapid-fire cannon with 150 RPG mounted in a hollow shaft. A 12.7 mm Berezin machine gun was synchronized and mounted on the engine cowling with 170 RPG. The LaGG-3 had many problems during production, the Klimov M-106 engine was powerful but unreliable. The Klimov M105, however, was more reliable but weaker. This led to the LaGG-3 being severely underpowered and disliked by many pilots. This led to Lavochkin's decision to install a more powerful Shvetsov M-82 radial. Which gave birth to one of the most feared fighters in the game: the La-5.

The breakneck rush to produce fighters in 1941, in tandem with an influx of unqualified personnel to aircraft plants, led to an unavoidable drop in quality in the assembly and machining of planes. The situation was worsened by an emerging shortage of Bakelite plywood, which had to be replaced with standard pine and birch. As a result, the LaGG-3's weight increased again, and its aerodynamic properties and flight characteristics decreased.
  
"A single-seat monoplane fighter made entirely of wood with a closed cockpit, low wing and retractable landing gear with a tail wheel.
+
Designers attempted to counteract the increased weight by weakening its weaponry yet again. The LaGG-3 Series 8 had its synchronized 7.62 mm ShKAS machine guns removed.
The appearance of the new German Messerschmitt BF-109 in Spain made it clear that Soviet aviation had become outdated. Several design collectives at once took it upon themselves to develop new fighters, including OKB-301 headed by the “triumvirate” of aircraft designers – S.A. Lavochkin, V.P. Gorbunov and M.I. Gudkov – with their I-301 design. 
 
 
 
The first prototype took its maiden flight on 28 March 1940. After the introduction of a range of upgrades to its design, the fighter went into series production in the beginning of 1941 under the designation LaGG-3.
 
  
The LaGG-3's airframe consisted entirely of wood. All its parts were attached with glue, without nails or screws. The most crucial parts were processed with Bakelite lacquer, a phenol formaldehyde resin.
+
The plane's armament now consisted of a 20 mm Shpitalny-Vladimirov ShVAK cannon in the cavity between the engine cylinders with 150 shells, and a 12.7 mm synchronized Berezina BS installed in the nose section of the fuselage above the engine and to the right with 200 rounds each.
  
LaGG-3 Series 1 planes went into production at the end of 1940 at the No. 21, No. 23, No. 31 and No. 153 aircraft plants in Nizhny Novgorod, Leningrad, Taganrog and Novosibirsk respectively. Following the LaGG-3 Series 1, series 2 and 3 planes went into production with practically no difference from the series 1 planes.  
+
This airborne armament configuration became standard, and remained unchanged (except for series 34 planes) until LaGG-3 series production ceased.
  
The LaGG-3 Series 1 was equipped with the water-cooled V12 Klimov M-105P (“Pushechny”, or “Cannon-type”) engine with a maximum output of 1,050 hp.
+
Externally, the LaGG-3 Series 8 planes differed in the absence of the now unnecessary ShVAK cannon fairings on the engine hood.
  
Its weaponry consisted of a 12.7 mm Berezina BK machine gun with 230 rounds, installed in the cavity between the engine cylinders; two 12.7 mm synchronized Berezina BS machine guns installed in the nose section of the fuselage above the engine with 240 rounds each; and two 7.62 mm synchronized ShKAS machine guns with 325 rounds each, installed in the nose section of the fuselage above the engine in large drop-shaped cowls.
+
The LaGG-3 Series 8 went into production at the end of 1941. LaGG-3 fighters of this model were produced right up until series 11 was launched.
  
As compared with the I-301, the series-produced LaGG-3's takeoff weight was significantly increased due to the installation of additional fuel tanks, the armored backrest of the pilot's seat, a radio kit and several other pieces of equipment. The fighter's flight performance decreased as a result, but was nonetheless considered fully acceptable.
+
Consequently, in less than a year, the LaGG-3 went from being a plane with excellent firepower to a fighter with a relatively average armament. Unfortunately, its "disarmament" only slightly improved its flight characteristics. The LaGG-3 still weighed nearly 300 kg more than the Yak-1, which was superior in speed, maneuverability and ascension rate. But worse still, it was not only inferior to its fellow Soviet Yak, but also to the German Messerschmitt, particularly its new Bf.109F model.
  
The first LaGG-3 was accepted into the military on 24 February 1941. Manufacturing of the LaGG-3 Series 1, 2 and 3 continued until the summer of 1941. In total, plants produced 322 planes of all three series before the beginning of the war."
+
Nonetheless, in spite of its drawbacks, the LaGG-3 was actively used on the front starting in August 1941. In the autumn of 1941, it was used on the Bryansk, Kalinin and Western fronts and in the Moscow Air Defense Force.

Description

GarageImage LaGG-3-8.jpg


The LaGG-3-8 is a rank I Russian fighter with a battle rating of 2.3 (AB), 2.0 (RB), and 1.7 (SB). It was introduced in Update 1.33.

The LaGG-3-8 is one of the first aircraft in the game to be armed with a cannon. It is also one of three Soviet fighters in rank I to be armed with a cannon, the others being the LaGG-3-11 and Yak-1. As the first monoplane fighter for many rank I Soviet pilots, a big change from the reserve biplanes, it is an introduction to a whole new range of tactics and armaments.

Survivability and armour

  • 8 mm Steel plate behind the pilot.

Armaments

Offensive armament

The LaGG-3-8 is armed with:

  • 1 x 20 mm ShVAK cannon, nose-mounted (150 rpg)
  • 1 x 12.7 mm Berezin UB machine gun, nose-mounted (200 rpg)

Usage in battles

The LaGG-3-8 should be flown mainly as a fighter. It can be used as a bomber hunter, but it is not well suited to this role due to its average rate of climb and fragile engine.

As a fighter, the LaGG-3-8 packs quite a punch at its low rank. The powerful cannon in the nose of the plane allows it to potentially dish out large amounts of damage to unsuspecting aircraft, biplanes, monoplanes and bombers alike. Its heavy armament makes it the perfect aircraft to pounce on carefully selected enemies that are on their own or engaged in a furball at low altitudes. Due to the average rate of climb, this aircraft is best used in diving attacks, booming and zooming in and out of the fray.

Another feasible tactic in the LaGG-3-8 is to take advantage of the nose centred armament in head-on attacks. Due to the aircraft's fairly robust airframe, it can take some hits in most areas, even from 20 mm cannons. When performing a head-on attack in the LaGG-3-8, take advantage of the central armament to take some shots from more than 750 m out, then pitching down and pulling to the side slightly. If you see that your opponent has committed to the head-on, pull the aircraft back on target and fire in long bursts.

If up against a fighter or single engine aircraft, aim for the main mass of the plane, the fuselage. If up against a heavy fighter or bomber, aim for a single engine or wing. Usually a burst of cannon fire into these areas will do them in. If you happen to come up against an aircraft with similar armament (central cannons), take a few pot shots, roll and dive out of the fight to a safe distance. However, against most other planes, the nose mounted armament of the LaGG-3-8 excels. Another thing to watch out for is the plane's fragile engine, as it can be easily knocked out by aircraft with heavier armament in head-on attacks.

At this low rank, there are many planes that can out-turn the LaGG-3-8. Although this aircraft can pull a very fast initial turn, in a sustained turn-fight it will start to show its faults. Its weak engine combined with a heavy airframe means that this aircraft bleeds energy very quickly in tight turns, nosing down during long, low speed turns. Once at this state of low energy, its average climb rate and acceleration worsens, posing it as an easy target for even the slowest of fighters.

In summary, the main points to take note of when flying this aircraft are:

  • Keep your speed and energy up
  • Use your dive speed and nose mounted cannon to your advantage
  • Go for unsuspecting targets when alone or in furballs
  • Perform head-on attacks against weaker targets
  • Don't engage in a sustained turn fight
  • Try not to get the engine damaged

Pros and cons

Pros:

  • Relatively fast for its battle rating
  • Good diving speeds
  • Average turn time
  • Fairly good roll rate
  • Strong armament for its battle rating
  • Reasonably high cannon ammunition capacity (150 rounds)
  • Armament centred in nose
  • Easy to fly

Cons:

  • Rate of climb is average at best due to weight and weak engine
  • Can be out-turned easily by biplanes
  • to nose down in sustained low speed turns
  • Low machine gun ammunition capacity (200 rounds)
  • Cannon and machine gun rounds follow different trajectories
  • Engine overheats and can be knocked out quite easily (liquid-cooled)

History

The LaGG-3 was designed by Soviet engineers Lavochkin, Gorbunov, and Gudkov to replace the LaGG-1. The original LaGG-3 prototype was made almost entirely out of wood. The airframe was made out of special multi-ply wood bonded with resin. The wings were similar to that of the Yak-1, the difference being the LaGG wing was made in two sections. The fuselage was similar to another Russian fighter, the MiG-3. Armament includes a 20 mm ShVAK rapid-fire cannon with 150 RPG mounted in a hollow shaft. A 12.7 mm Berezin machine gun was synchronized and mounted on the engine cowling with 170 RPG. The LaGG-3 had many problems during production, the Klimov M-106 engine was powerful but unreliable. The Klimov M105, however, was more reliable but weaker. This led to the LaGG-3 being severely underpowered and disliked by many pilots. This led to Lavochkin's decision to install a more powerful Shvetsov M-82 radial. Which gave birth to one of the most feared fighters in the game: the La-5.
