Description

GarageImage La-9.jpg


The La-9 is a Rank IV Soviet fighter with a battle rating of 5.7 (AB), 6.0 (RB), and 6.3 (SB). It was introduced in Update 1.37.

The La-9 main armament consists of four synchronized Nudelman-Suranov NS-23 23mm cannons located in the upper part of the nose with a total burst mass of 7,90 kg per second(with default belts). The total ammo capacity is only 300 rounds (75 rounds per gun), so make sure the hits count if flying in realistic battle or simulatory battle. The muzzle velocity of the shells lies at 690 ±10 m/s[3].

An important feature of the Soviet fighters armament is its ability to either fire the upper pair of cannons or the lower pair of cannons. This becomes particularly useful when in need of conserving ammo in realistic battle or simulatory battle because 2 cannons are still enough to easily kill any fighter. Only against resistant and well-defended bombers such as the B-29 is it really necessary to fire all the guns. When firing all 4 at once, be mindful of the powerful recoil as it tends to lift the nose slightly upwards as well as slowing the plane down, since the nose guns are placed above the centre of gravity (this becomes especially noticeable when the throttle is cut down to 0%). In high G turns this push will allow pilots to turn a bit tighter, making deflection shots easier to some regard. Beware that in Simulator Battle the sudden increase of angle of attack may result in a stall if the aircraft was already being pushed to its limit. The NS-23 gun possesses a high rate of fire of 10 rounds per second. With 4 guns those are 40 rounds per second. While the rate of fire is 20% slower then that of ShVAK cannons the higher weight of rounds more than makes up for it in terms of damage output. Combined with low ammo capacity per gun it is crucial to maintaining trigger discipline and fire in short bursts.

The ballistics of the cannons can be considered bad and usually require a lot of time getting used to before becoming proficient with them. The drop and spread of the shells is particularly noticeable when firing at large distances.

Armaments

Offensive armament

Main article: NS-23 (23 mm)

The La-9 is armed with:

  • 4 x 23 mm NS-23 cannon, nose mounted (75 rpg = 300 total)

Usage in the battles

Arcade Battles: As all planes, the La-9 has a boosted Flight Model (FM) in the Arcade mode, which allows for better overall performance, from speed and climb rate to maneuverability. It performs best at an altitude of 3400 m and below. The main reason for this is the absence of War Emergency Power (WEP) at altitudes above 4000 m. To be able to use WEP at altitudes between 3400 m – 4000 m it is necessary to maintain a good speed.

In terms of top speed, a fully upgraded La-9 is among the fastest planes at sea level in the game, allowing it to easily outrun most opponents. The acceleration is good even without WEP, but with it, becomes amazing, however, keep in mind not to overuse it and thus overheating the engine. Although it can be cooled off easily by lowering the throttle, thanks to the ASH-82FN being an air-cooled engine, once overheated both the top speed as well as acceleration take a noticeable loss in performance.

The La-9 is not a particularly maneuverable plane and should avoid dogfights in most cases as even if won, they are likely to take long enough and leave the plane low on speed – a tempting target for other enemy fighters.

The climb rate of the plane is great until the fighter reaches 4000 m after which it becomes somewhat moderate in comparison to other planes at tier IV, due to the absence of WEP at higher altitudes. The best IAS (Indicated airspeed) for climbing is 250 km/h.

Another important trait of this fighter is its energy retention, in arcade battles, it is possible to safely dive from 4,000 m to 1,000 m and still be able to recover all that altitude, it also helps to keep flying at above max speed after a dive longer than the average competition at its level.

Maximum true airspeed (TAS) depending on altitude in arcade battle

In Ground Strike battles, La-9 pilots have two choices:
Helping to secure altitude and bomber hunting/escorting – A high risk/high reward option, best attempt this if the La-9 is almost or already fully upgraded. At the start of the battle side climb for a bit, but don’t get too separated from friendly fighters that are also climbing. It is important to avoid the initial clash since the La-9 isn’t very maneuverable and with numerous enemies flying around – an easy target. Instead, provide cover for one of the more nimble teammates that have engaged in a dogfight. Once air superiority has been established, either pursue enemy bombers or escort friendly bombers by killing any climbing attackers. Should the team fail in establishing air superiority don’t stay up high as the La-9 gets outperformed by most fighters at higher altitudes, kill any enemy bombers within reach and proceed to the second option.

Covering ground targets and attacking low flying enemies – A relatively low risk/decent reward option, the most appropriate when the player doesn't have the plane upgraded (i.e. when it is in "stock" condition). The best way to do this is to fly the La-9 an altitude of 2,000 m - 3,000 m and to position it either at the flanks of the map or directly in front of friendly fighter spawn. A certain distance is to be kept from the core of the enemy airspace, whilst attacking low flying bombers and attackers to protect friendly ground targets, or whilst finding and engaging a fur ball from above and performing Boom and Zoom attacks on the enemy fighters below. In case of danger, speeding away towards the enemy team's fighter spawn ought to resolve any issues.

Domination mode is arguably the best mode for the La-9 because most enemies are flying below 4,000 m and are thus always allowing the fighter to perform at its best. The approach to Domination battles is always simple yet effective. With the plane above contested airspace at around 2,500 m altitude, one should dive down on an enemy, shoot and extend towards teammates. Once safe, it is time to regain altitude and repeat the process. The La-9 is also capable of quickly capturing airfields since it's powerful 23 mm cannons can be fired to use the recoil as a quasi-airbrake.

In the Realistic and Simulator modes the FM of the La-9 is no longer boosted in any way. However, the plane is still at its best below 4000 m, as the WEP is unavailable above 4000 m just as in the arcade mode. The speeds required to apply WEP at altitudes from 3000 m to 4000 m vary slightly from those in AB, but the main idea remains the same – high speed is required.

In realistic and simulator battles start by climbing to an altitude of 2500 m (if cloudy) or 3000 m (if the weather is clear). Climbing higher than that is only advised if not alone as the La-9 will be outperformed at high altitude by most enemies. The key to success in the La-9 is teamwork, so consider squading up with a friend. Since it is a bad idea to dogfight, try to get an enemies attention by acting as bait and lure him down to sea level instead. Once the enemy loses his altitude advantage, it is time for the squadmate to attack. Once low the pursuer won’t be able to either catch the bait nor escape your ally – an easy kill. Be also sure to target any enemies that are flying low, if the La-9 has an altitude advantage use Boom & Zoom tactics, if the plane is on the same low altitude as the enemy, perform high-speed fly-bys.

Maximum speed (TAS) depending on altitude in RB/SB

Even if not as fast as in arcade battle, it remains among the fastest fighters at low altitude in RB and SB, while also having great acceleration with WEP applied. Keep in mind that this only applies, if the engine isn’t overheated – to cool it off, lower the throttle; it will only take a couple of seconds.

Both the maneuverability and the climb rate take a drop in performance as well, but the general rule stays the same. Try to avoid dogfights and don’t climb above 4000 m unless not alone or there are no enemies above the La-9. The best IAS for climbing remains 250 km/h.

While the energy retention of the La-9 after a dive in RB and SB is great, one shouldn’t dive for more 2 -2,5 km at a time, because the plane quickly reaches its maximum allowed speed of 850 km/h IAS or roughly 910 km/h TAS (true airspeed, default speed measurement). Not only that but at speeds above 750 km/h IAS it becomes hard to pull up from a dive due to noticeable control stiffening.

A separate characteristic of the fighter which only really comes into play in RB and SB is the minimal amount of fuel a player can take into battle, which is currently enough for 45 minutes of flight time. In prolonged matches it allows the La-9 to simply outlast its enemies. Once around half of the fuel is consumed an increase of the fighters speed, climb rate, but most importantly roll rate becomes noticeable which is likely to come in handy late game.

This last feature is currently only really useful for SB players. The La-9 is currently one of the planes for which the canopy of the cockpit can be opened to improve the visibility at the expense of some top speed.

Specific enemies worth noting

When fighting German aircraft, the toughest opposition will be late Bf 109’s and aircraft of the Fw 190 D series (together with their cousin, theTa 152 H-1.

The former are deadly opponents above 4,000 m that are well capable of outmaneuvering the La-9 due to the Soviet fighter's absence of WEP at high altitudes, having also an advantage in regards of climb rate. This leaves the La-9 pilot with two options, either acting as bait - making the 109 loose energy and become vulnerable - or diving down. At lower altitudes, the La-9 regains a fighting chance, but it is usually a tense battle where the deciding factor will be the pilot’s individual skill. Don’t forget to use combat flaps.

Fw 190 D series/Ta-152 – similar to the Bf 109, these German aircraft possess a climb and also a speed advantage above 4000 m. However, they will be out-turned by the La-9 in the horizontal, though it may take a while. At lower altitudes, these planes are easy targets as they hold no significant advantages, except for roll rate and considerable firepower. It is unwise to perform head-on attacks against them.

When fighting British aircraft, naturally, different tactics are to be employed.

Late Spitfires, such as the Mk. XVIIIe or the Mk. 22 variants, can easily out-do the La-9 in the department of turn radius, so employing turn-heavy tactics is heavily discouraged. Their well-performing Rolls-Royce Griffon engines also grant them a better output at higher altitude, which means that fighting above 4,000 m for the La-9 puts the Soviet pilot at a disadvantage. These Spitfires, however, are not as fast as the La-9 nor do they maneuver as well at high speed. Therefore, engagements against these aircraft should consist of Boom & Zoom and Boom & Run oriented tactics.

The Tempest Mk II is of, all piston-engine enemies, the La-9's most deadly adversary. Any opportunity to engage one in an advantageous situation should be seized - lest the Tempest is given the upper hand and the La-9 becomes prey. Unlike other piston-engine planes, the Tempest is among those few planes that can rival the La-9 in terms of top-speed at lower altitudes. Climb rate and turn rates are similar, but the British fighter has the edge. To defeat one, very skillful defensive flying is required. The best course of action is to set the Tempest up for an attack on a teammate. One factor that can prove to decide on both sides is knowing how to use Manual Engine Controls.

Counter-tactics

The best way to fight the La-9 is by exploiting its weaknesses – poor maneuverability in dogfights and poor high altitude performance. If flying a more maneuverable plane (F8F-1B, Spitfires, Ki-84, N1K2 or Yak-9UT), turn-intensive tactics are recommended. If the La-9 commits to it, an easy kill is at hand, if not, one ougt to climb and employ the tactics recommendable when flying less maneuverable fighters.

A less nimble plane (Fw 190, Bf 109 K, F7F etc.) should, once above 4000 m hold on to that altitude and get in position for Boom & Zoom runs. The only way to catch the La-9, if it is going at full speed at low altitude, is by diving on one, so an altitude advantage is the key to success.

The two most important modules that should be unlocked as soon as possible are the Offensive 23 mm belts and Engine injection. The first gives access to the devastating air target ammo belt while the second one gives a huge boost to the fighters flight characteristics. Difference between a completely stock and a fully upgraded plane is huge (see screenshots in post below), and the first 50 or so battles will be very challenging.

The recommended order of research is as follows:

1-Offensive 23 mm belts
2-Radiator
3-Compressor
4-Engine
5-Wings repair
6-Engine Injection
7-Everything else, based on personal preferences

The total amount of Research Points(RP) necessary to unlock all modules on the La-9 lies at 167000 RP and makes it the most expensive plane in terms of RP to upgrade in all of Soviet tier IV. Curiously enough only 120000 RP are needed to research the plane itself.

One other camouflage besides the default one is currently available – Unicolor Grey Camouflage, which requires 350 player kills in the La-9 to be unlocked.

In-game description

"A single-seat all-metal cantilever monoplane fighter. Continuing the line of the La-5/La-7 fighters, the designers of the Lavochkin Design Bureau wanted to remove all of the wood from the aircraft's construction and create an all-metal fighter. In early 1946, prototype fighter 130 was built, to be launched into full-scale production under the designation of La-9 (Product 48) after the tests had been passed.

The La-9 was a new plane, not just an upgrade of the La-7 with metal parts instead of wooden ones. The La-9 had differently shaped monospar wings with laminar flow airfoils. This plane did not have leading edge slats. The weight savings gained by replacing wood with duralumin enabled the designers to mount five fuel tanks on the aircraft and increase the total fuel capacity.

The La-9's cockpit was more spacious than the La-7's, and its canopy required less framing and provided better visibility. By pressurizing the cockpit and the power unit compartment, one of the main shortcomings of the Lavochkins - the high temperature in the pilot's cockpit during engine operation - was finally overcome. Also, the aircraft's instrumentation system was brought into line with worldwide standards. A radio compass, an attitude indicator, and an identification-friend-or-foe transponder enabled the aircraft to be piloted and engage in dogfights even in difficult weather conditions.

The La-9 had a Shvetsov ASh-82FN fourteen-cylinder two-row radial air-cooled fuel-injected engine producing a maximum power of 1,850 hp. The plane's armament consisted of four synchronous 23mm Nudelman-Suranov NS-23S cannons with 300 rounds each. A Fairchild gun camera mounted on the right wing panel was used to direct shooting and for training purposes. Later it was replaced with an S-13, its Soviet counterpart, which was placed in the fairing over the cockpit windshield.

Production of the La-9 continued until 1949. A total of 1,882 planes were manufactured. Troops in the Soviet Air Force began to receive the new fighters in 1947. The La-9 did not remain in service for long, since the Air Force quickly switched to jet technology. The early 1950s saw the beginning of the mass handover of piston fighters for warehousing and conservation, as well as the re-equipping of fighting troops with MiG-15 jet aircraft.

In addition to flying with the Soviet Air Force, La-9 fighters remained in service with the People's Liberation Army Air Force of China until 1959, laying the foundation for the new Chinese Air Force. When the Korean War began, the La-9 was being supplied to the North Korean Air Force. The first planes were received in September and October 1950. During the final stage of the war, the Koreans used the La-9s as light night bombers. When bomb racks were mounted, the fighter could carry two 50-kg bombs. After the war, La-9s were in service with the Korean People's Army Air Force until the end of the 50s."
