General info

The La-5FN in the garage.

The La-5FN is a Rank III Soviet Fighter with a battle rating of 4.0 (AB/SB) and 3.7 (RB). It was in the game since the start of the Open Beta Test prior to Update 1.29.

The main purpose, usage and tactics recommendations

General play style

The La-5FN is a strong contender at its level that can provide very intense experiences. The La-5FN is a plane with a heart, that excels in dogfighting thanks to its engine power and roll rate, with a quite competitive turning ability. The La-5FN can get in the middle of a fight, pull some aggressive speed-costly maneuvers and then escape the fight using its climb rate and/or speed.

Against aircraft that are similarly designed to dogfight intensely, like the Bf-109, the La-5FN meets a challenge that can only be won by outwitting the opponent, when altitude and speed advantages are not present. In this case, constant dogfight maneuvering will be needed, and throttling down and up again,and doing barrel rolls and yo-yo'ing will be a constant in the fight. In SB, the extreme cockpit visibility enables more intense maneuvering without losing sight of the enemy. In AB though, the fact that lots of enemies will be in one place at a time means that keeping energy is very important. Despite that, this aircraft wins an advantage in Arcade Mode, since it can use its great dive acceleration without fear of reaching wing-ripping speeds, since wing overload and over speed crashes don't happen in this mode. In other modes, particularly in RB, the low dive limit is a great limitation to an otherwise very complete aircraft. Against very nimble aircraft, like the A6M3 Reisen and the Spitfires, Boom and Zoom tactics are recommended. Attacking clean and safely is the wisest choice, and when being chased, a shallow dive can usually bring safety to the La-5FN pilot. The engine power of this fighter aircraft means that it can be afford to lose a fair amount of energy in a fight against these aircraft and still come out on top, but this is not very recommendable, as patience will always be more rewarding.

Tactics

Specific enemies worth noting

A6M Reisen: Japanese planes will easily out turn and out manouever you. Avoid these type of engagements against the A6M Reisen and go for boom and zoom attacks.

Modules and improvements

History of creation and combat usage

In June 1942, Arkadiy Shvetsov's factory in Perm completed testing of the new M-82FN radial engine. This new version of the M-82 featured direct fuel injection into the engine cylinder heads, as opposed to the carburetors used by the earlier M-82 and M-82F. The engine also featured an enlarged cylinder ribbing to improve in-flight cooling (the M-82 proved to be quite prone to overheating on the La-5), reinforced pistons and rods, and an exhaust pipe fitted to each individual cylinder. The new engine’s output increased to 1,850hp at low level, 1,670hp at 5,000ft, and 1,460hp at 15,000ft.

The first Lavochkin La-5 with the new M-82FN was tested in December 1942, using the older Type 37 air frame without the cut-down rear fuselage. The definitive La-5FN prototype using the new Type 39 air frame was completed in March 1943 and submitted for state testing. The new air frame featured numerous improvements besides the new M-82FN engine: fuselage pressurization, a retractable tail wheel, larger tail surfaces to improve handling and reduce stick forces when manoeuvering, the radio mast was angled against the airflow, and the air intake for the gear-driven supercharger was enlarged atop the engine cowling. Metal wing spars were used for lightness and strength. The new La-5's performance was outstanding: a maximum speed of 372mph at low level using boost, 391mph at 10,500ft and 405mph at 20,500ft.

Despite its outstanding performance, production of the La-5FN was slow due to a lack of M-82FN engines. The first La-5FNs began entering service in the summer of that year, arriving just in time to participate in the titanic Battle of Kursk. With the La-5FN, the VVS-KA finally achieved parity in terms of fighter quality with the German Bf 109 G-2/G-6 and Fw 190 A-3/A-4. Among the most famous pilots of the La-5FN was the Allied ace of aces, Ivan Kozhedub, who gained 45 of his 62 victories in the La-5FN. Further improvements to the La-5FN would lead to the so-called '1944 standard La-5FN', which would enter service as the La-7.

Ingame description

The Lavochkin La-5 was a single-engine monoplane fighter, a single-seater with an enclosed cockpit, wooden frame and a canvas skin. FN in the designation stands for Boosted, Fuel Injection. The new variant entered production and began to reach front-line units in March 1943. The La-5FN, rather than being a successor to the earlier La-5F, was produced concurrently. Its ASh-82FN engine could reach 1,850 HP and remain at takeoff power settings for up to 10 minutes.

In April 1943 a serial La-5FN was flight tested in mock combat against a captured Bf-109G-2. The Soviet aircraft proved superior at low and medium altitudes, the most common on the Eastern Front. The La-5FN was superior both in top speed as well as maneuvering in the vertical. An analysis of these engagements led to significant changes in Soviet tactics. The La-5FN's armament was identical to that of the La-5 and consisted of twin 20mm ShVAK cannon with 200 rounds per gun. The guns were pneumatically or mechanically operated.
