Description

The Yak-1 is a Rank I Soviet fighter with a battle rating of 2.3. It was introduced in Update 1.43.

The Yak-1 is a fairly good turn fighter. Although not as good as Spitfires around the same BR, its better than some of the German aircraft. The aircraft has good diving speed and energy retention, however without slats, it cannot out-turn a 109 F in a vertical loop. This aircraft performs best at medium-low altitudes. Due to its small wings and poor rate of climb at higher altitudes, it lacks as a high altitude fighter. The aircraft can be used in horizontal turn fighter, one must be careful to be on the lookout for Boom & Zoomers. If the situation gets bad, a possible escape can be flying low level at high speed or trying an energy-retaining climb. While this aircraft should not be wasted on ground attack, as last resort it can be used to destroy unarmoured ground targets if the last flying opponent happens to be running away. The aircraft does performs well at lower speeds, yet it becomes most vulnerable to most enemy aircraft including biplanes.

Used well, the Yak-1 can be an unstoppable flying machine. Two of the most important things a Yak-1 pilot should aim for are the opponent's cockpit (pilot sniping) or wings. These are typically the weakest spots of an aircraft where a good shot can knock-out the enemy pilot or snap off a wing with a few well placed rounds. The ShVAK is a fantastic weapon 20 mm cannon if your aim is good! This cannon has an excellent rate of fire, unfortunately it is paired with a barely adequate amount of ammunition which can be used up quickly. Mounted along side the ShVAK are two 7.62 ShKAS machine guns. Much like the cannon, the machine guns do not have a large ammo pool to draw from. Yak-1 pilots always need to be mindful on how much ammo remains after an encounter or risk being pounced on by more maneuverable enemies when out of ammunition (or reloading in AB).

An Achilles Heel of the Yak-1 is that it lacks armour protection. Head-on attacks from an enemy risk your pilot being knocked out by flying rounds or your water coolant radiator being hit. With a leaking water radiator, the Yak-1 will suffer engine failure with in a few minutes (in RB mode). The engine of the Yak-1, like most Russian fighter engines, tends to overheat quickly and stays running hot. One way to combat overheating is to run the engine at 97% of maximum and limiting usage of WEP. If the aircraft is damaged, the Yak-1 pilot can check the cockpit’s instrument panel (refer to the instrument panel image above) and observe the oil temperature gauge as this will give you a more accurate state of the engine than the water temperature gauge.

Survivability and armour

• 8 mm Steel - Plate behind pilot's seat
• No armour glazing
• Critical components located at front of aircraft (fuel, pilot, engine, controls)
• Fuel tanks located in wings near fuselage

Armaments

Offensive armament

The Yak-1 is armed with:

• 1 x 20 mm ShVAK cannon, nose-mounted (110 rpg)
• 2 x 7.62 mm ShKAS machine gun, nose-mounted (620 rpg = 1,240 total)

Suspended armament

The Yak-1 can be outfitted with external ordinance:

• Without load
• 2 x 50 kg FAB-50 bombs (100 kg total)
• 2 x 100 kg FAB-100 bombs (200 kg total)

Usage in the battles

Due to the Yak-1’s maneuverability and armament, it’s main role will be employed as a fighter in game. The Yak-1 can be used as a turn fighter (see next section for aircraft to avoid while turn fighting), boom & zoom and energy fighting. The Yak-1 performs well in the mid to lower altitudes, but loses mobility in the higher altitudes.

• Ground attack: This should be avoided due to low speeds needed allowing the Yak-1 to become an easy target for enemy aircraft (especially biplanes).

• Bomber hunting: This is a risky option as bombers typically fly in the higher altitudes where the Yak-1 starts losing its maneuverability. The lack of armour on the Yak-1 makes it vulnerable to turret gunners and it is very easy to lose your pilot, engine or a wing to them. When hunting bombers, the Yak-1 can utilize a head-on approach going for the pilots (pilot sniping) or the engines; otherwise employ the speed of the Yak-1 by diving from a higher altitude towards the front of the bomber aiming for the cockpit, engine or wings. If you fail to destroy the bomber on the first pass, exercise patience and set up for another diving pass, any other way the Yak-1 risks bleeding crucial speed in making a quick turn in an attempt to finish off the bomber. Here, quick turns will expose you to any turrets on the plane which would otherwise have a very difficult time acquire a firing a firing solution on a zooming fighter which is quickly out of their range.

Specific enemies worth noting

• Spitfires: The Spitfire's superior turning ability gives it an edge over the Yak-1's maneuverability. Turn fighting against a Spitfire is very difficult in a Yak-1's, usually resulting in the Yak-1 being unable to shake or out run the Spitfire. Baring any mistakes made by the Spitfire pilot, the Yak-1 will have a very difficult time gaining an advantage or escaping.

• A6M Zeroes: Much like the Spitfires, the A6M Zeros are superior turn fighters and have the added bonus of being armed with 20 mm auto cannons giving the Japanese fighter a firepower boost against the Yak-1.

Counter-tactics

When attacking a Yak-1, specific areas to exploit:

• When attacking in a Spitfire or A6M Zero, engage in a turn fight, bait the Yak-1 into tight turns to bleed its speed.

• Bait the Yak-1 to higher altitudes, the higher it goes, the less maneuverable it becomes and the more limited their options become.

• The Yak-1 does not have any armour plates in the front and is susceptible to pilot sniping, wing snapping, engine/fuel tank fires and overheating with a few well placed shots from cannons or machine guns.

• Non-turn fighting aircraft should rely on Boom & Zoom tactics in attempt to take out a Yak-1.

If you find a Yak-1 on your tail you can attempt:

• A drastic speed reduction and turn in hopes of an overshoot.

• Keep moving around so the Yak-1 cannot get acquire a firing solution with its cannon, causing the Yak-1 to expend all of its rounds (in AB this then gives you a ~ 40 second window to attempt to get away or reverse roles before the Yak-1 cannon has reloaded).

• Drag the Yak-1 back towards teammates and set the Yak-1 up to be an easy target for your comrades to take out.

Pros and cons

Pros:

• Powerful cannon with limited ammo/dual machine guns with an adequate amount of ammo.
• Good low level acceleration.
• Good top speed at low altitudes.
• Even though it's frame is constructed of wood, the Yak can take a lot of punishment and still perform well.
• Highly maneuverable

Cons:

• Engine overheats quite easily, forcing the pilot to slow down or return to base to allow it to cool (engine is notorious for overheating and ceasing to work in mid-dogfight if run at 100% or WEP). Operating the engine at 97% reduces chances for engine overheating while maintaining very good aircraft performance
• No armour to protect pilot from the front, engine or fuel tanks, almost doomed if set on fire.
• Cannon ammo runs out very quickly if not carefully monitored (in AB, reloading at every opportunity is advised)
• Single powerful gun requires good aim and knowledge of aircraft weak spots to be used effectively ("spray and pray" causes ammo to deplete very quickly)

History

In 1939 the Soviet Command was looking for a replacement for their outdated I-153 Chaikas and I-16 Ishaks. Jakovlev was part of a soviet delegation on a visit to the German aviation industry in October 1939. His interest was in aerodynamic design and during a visit at Heinkel, their new radiator lacking He 100 fighter was shown to them. Three (or ten) vehicles were bought by the CCCP. While the He 100 was producing record level top speeds, the surface cooling technology and other handling characteristics tainted the aircraft with the Soviets and was marked unsuitable, like in Germany.

Already by January 1940 a first prototype was ready for take off. Baptized I-26 (Istrebitel -> Fighter), the test flights were marked by a horrible accident as Julian I. Piontkowski, test pilot for every Yakovlev plane, crashed and died. Fortunately for the plane's designers the aircraft's construction was not found to be the cause of the accident and state supervised tests continued until November 1940. Serial production subsequently started in December 1940 under the new designation "Yak-1".

By the time of the German invasion, all of the new fighters were delegated to the defence of Moscow, as was the MiG-3.
