The '''{{Specs|name}}''' is a Rank {{Specs|rank}} German fighter {{Battle-rating|2}}. It was in the game since the start of the Open Beta Test prior to Update 1.29. The K-4 is the pinnacle of the famed [[Bf_109_(Disambiguation)|109 series]]. The `'''K'''urfürst´ frame is the last iteration and was focused on ease of production rather than performance, yet it features the best power to weight ratio and acceleration of any 109, turning this machine into a beast. However, the age of the design is showing with bad high speed characteristics.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} German fighter {{Battle-rating}}. It has been in the game since the start of the Open Beta Test prior to Update 1.27. The K-4 is the pinnacle of the famed [[Bf_109_(Disambiguation)|109 series]]. The ''''K'''urfürst' frame is the last iteration and was focused on ease of production rather than performance, yet it features the best power to weight ratio and acceleration of any 109, turning this machine into a beast. However, the age of the design is reflected in its poor high-speed characteristics.
  
Use your outstanding climb rate and keep speed. Your main principle of combat should be energy fighting tactics. Up to its top-speed (as this feature is derived from the engine) it has a good acceleration with WEP. This grants the machine reasonable zoom abilities. If chased, dodge away from your enemy with fancy manoeuvers without losing too much speed. In Realistic Battle try to do a climb spiral, but be sure you are in a better energy state! A miscalculation and the foe will have the opportunity for an easy deflection shot.

Use the plane's outstanding climb rate and speed retention. Energy fighting tactics should be this plane's primary mode of fighting. It has good acceleration when using WEP. This grants the machine reasonable zoom climbing abilities. If chased, dodge away from the enemy with fancy manoeuvres without losing too much speed. In Realistic Battles, try to do a climbing spiral, but be sure to be in a higher energy state than the enemy! A miscalculation and the foe will have the opportunity for an easy deflection shot.
  
However, there are also downsides. Top-speed can be reached quickly, yet it is not fast when stock. While it does have an edge in agility, it has bad low-speed manoeuvrability. Furthermore, these foes will not usually engage in manoeuvering combat; rendering this advantage moot.

However, there are also downsides. The top speed can be reached quickly, yet the plane is not fast when stock. While it does have an edge in agility, it has bad low-speed manoeuvrability. Furthermore, foes will not usually engage in manoeuvring combat, rendering any manoeuvrability advantage moot.
  
K-4 can outmanoeuver these planes at medium speeds (<450 IAS/kph): [[P-51]] (all types), [[P-47D-28|P-47D]], [[Typhoon_Mk_Ib/L|Typhoons]] and the [[La-9]]. However it will have a hard time on dealing with other late Rank IV aircraft, especially Spitfires. It is highly recommended that you use rudder during rolls as this increases roll rate dramatically. This is useful if you're trying to force a dive overshoot or avoid shots.

The [[MK 108 (30 mm)|MK 108]] is a double-edged sword: Nicknamed by the allies for its characteristic sound, the `''Jackhammer''´ is true to its name. Slow but powerful. Its '''main purpose''': Demolition of heavy objects, such as fortresses, preferably B-17G.<br />All this does not help for its '''''common''''' '''purpose''' in War Thunder: Hunting fighter planes. The cannon's rate of fire is extremely low, making it good for conserving ammo, but bad for deflection shots. Furthermore, the minengeschoß-shells are slow; very slow. Either one becomes very good at aiming their shots, or does the historic thing and closes the distance. Kills are generally done below 300 m/400 yards, if not closer. On the plus side, the damage is equivalent to most 37 mm cannons upon hitting. Tip: In order to better learn and understand the cannon's trajectory; do not fire with machine guns.
 
  
The two additional machine guns are best fired alone. The [[MG 131 (13 mm)|MG 131]] features HE shells (named IAI ingame) as ''Tracer belt''. Yet they are only an interesting choice for Simulator Battle, where they will deal good damage to control surface areas, causing inexperienced pilots to lose control. In Arcade and Realistic battle however, the instructor will dampen any such effects. Here, the damage-based ''Stealth-'' and ''Fighter belt'' fare better.

The plane should equip one of two load-outs: with either the single 30 mm cannon or 2 x 20 mm cannons. The single 30 mm is very capable of taking out 2-3 bombers and the low muzzle velocity matters less due to the large targets. The 3 x 20 mm cannons are very capable of taking out fighters due to the high shell density and sheer damage output. A single 20 mm does not deal enough damage and the 30 mm with gun pods is rather ineffective due to the differing muzzle velocities of the 30 mm and 20 mm cannons.
  
The plane should be played with 2 load-outs: either the single 30 mm Canon or 3 x 20 mm Cannons. The single 30 mm is very capable of taking out 2-3 bombers and the muzzle velocity matters less due to the large targets. The 3 x 20 mm cannons are very capable of taking out fighters due to the high shell density and 2 of your guns being on the wings. The single 20 mm does not deal enough damage and the 30 mm with gunpods is rather ineffective due to the different muzzle velocities.

One technique you can use is the prop pitch technique. Most of the later 109s have this but it is really effective in the 109 K-4. The prop pitch technique is using Manual Engine Control (found in sim controls) to set your prop pitch to 100% but throttle to 0%. This will make your prop, a giant air brake and is very helpful in forcing overshoots of the enemy aircraft. It can also be very helpful in diving where you might get dangerously close to your rip speed.

The true acceleration power of the plane is only achieved very late into the grind. Specifically, the Tier 4 ''Engine injection'' modification provides a significant boost and is a top priority. On the way there, all engine upgrades should be taken. 13 mm belts are helpful for removing tracer rounds. The 20 mm gun pods with belts and the gun upgrade are viable choices but engine injection remains a priority.

The Bf 109 K-4 was one of Kurfurst Bf 109 series, Kurfurst was the last series of 109 before war's end. The K series was the most upgraded and most expensive 109 and with war coming to an end not many were built. Work on the K series began in the spring of 1943 and prototype was ready by autumn of the same year. The series began production in August 1944 with the K-4 but due to changes to the design and delays with the new DB605D engine, the K-4 was the only one to be mass produced. Externally, the Kurfurst series had changes in radio equipment location hatch. A filler point for the fuselage fuel tank, and with removal of the D/F loop, were the main external differences to other Bf109 series. The landing gear also had doors that closed up the bottom completely and armament was the Motorkanone 108 (30 mm) , 2 x MG 131 (13 mm), with additional 2 gun pods of MG 151 (20 mm). Payloads included a 500 kg bomb or on rare occasion Wfr.Gr.21 Rockets (21 cm). Due to limited resources many of the variants didn't enter production.

Description

GarageImage Bf109K4.jpg


The Bf 109 K-4 is a rank IV German fighter with a battle rating of 6.0 (AB) and 5.7 (RB/SB). It has been in the game since the start of the Open Beta Test prior to Update 1.27. The K-4 is the pinnacle of the famed 109 series. The 'Kurfürst' frame is the last iteration and was focused on ease of production rather than performance, yet it features the best power to weight ratio and acceleration of any 109, turning this machine into a beast. However, the age of the design is reflected in its poor high-speed characteristics.

Use the plane's outstanding climb rate and speed retention. Energy fighting tactics should be this plane's primary mode of fighting. It has good acceleration when using WEP. This grants the machine reasonable zoom climbing abilities. If chased, dodge away from the enemy with fancy manoeuvres without losing too much speed. In Realistic Battles, try to do a climbing spiral, but be sure to be in a higher energy state than the enemy! A miscalculation and the foe will have the opportunity for an easy deflection shot.

However, there are also downsides. The top speed can be reached quickly, yet the plane is not fast when stock. While it does have an edge in agility, it has bad low-speed manoeuvrability. Furthermore, foes will not usually engage in manoeuvring combat, rendering any manoeuvrability advantage moot.

K-4 can outmanoeuvre these planes at medium speeds (<450 km/h IAS): P-51 (all types), P-47D, Typhoons and the La-9. However, it will have a hard time dealing with other late Rank IV aircraft, especially Spitfires. It is highly recommended to use rudder during rolls as this increases the roll rate dramatically. This is useful if when trying to force an overshoot or when avoiding shots.

Survivability and armour

The 109 K-4 has a very substantial amount of armour around the pilot but is mainly to protect the gigantic fuel tank your pilot is sitting on top off. The fuel tank, however, is self-sealing.

Armaments

Offensive armament

The Bf 109 K-4 is armed with:

  • A choice between two presets:
    • 1 x 30 mm MK 108 cannon, nose-mounted (65 rpg) + 2 x 13 mm MG 131 machine guns, nose-mounted (300 rpg = 600 total)
    • 1 x 20 mm MG 151 cannon, nose-mounted (200 rpg) + 2 x 13 mm MG 131 machine guns, nose-mounted (300 rpg = 600 total)

Suspended armament

Main article: MG 151 (20 mm)

The Bf 109 K-4 can be outfitted with the following ordnance:

  • Without load
  • 2 x 20 mm MG 151 cannons, wing-mounted (135 rpg = 270 total)

Usage in battles

The Bf 109 K-4's instrument panel.

The MK 108 is a double-edged sword: Nicknamed by the allies for its characteristic sound, the `Jackhammer´ lives true to its name. Slow but powerful. Its main purpose: Demolition of heavy objects, such as the B-17G Flying Fortress. However, its common purpose in War Thunder remains to hunt fighter planes. The cannon's rate of fire is extremely low, making it good for conserving ammo, but bad for deflection shots. Furthermore, the minengeschoß-shells are slow- very slow. One must either become very good at leading the shells or close the distance. Kills are generally done from 300 meters away, if not closer. On the plus side, the damage is equivalent to most 37 mm cannons upon hitting. Tip: In order to better learn and understand the cannon's trajectory, do not fire in conjunction with the machine guns.

The two additional machine guns are best fired alone. The MG 131 features HE shells (named IAI in-game) as the Tracer belt. Yet they are only highly effective in Simulator battles, where they will deal good damage to control surface areas, causing inexperienced pilots to lose control. In Arcade and Realistic battles, however, the instructor will dampen any such effects. Here, the damage-based Stealth and Fighter belts fare better.

The plane should equip one of two load-outs: with either the single 30 mm cannon or 2 x 20 mm cannons. The single 30 mm is very capable of taking out 2-3 bombers and the low muzzle velocity matters less due to the large targets. The 3 x 20 mm cannons are very capable of taking out fighters due to the high shell density and sheer damage output. A single 20 mm does not deal enough damage and the 30 mm with gun pods is rather ineffective due to the differing muzzle velocities of the 30 mm and 20 mm cannons.

One technique you can use is the prop pitch technique. Most of the later 109s have this but it is really effective in the 109 K-4. The prop pitch technique is using Manual Engine Control (found in sim controls) to set your prop pitch to 100% but throttle to 0%. This will make your prop, a giant air brake and is very helpful in forcing overshoots of the enemy aircraft. It can also be very helpful in diving where you might get dangerously close to your rip speed.

IV Engine injection Cover New 30 mm cannons New 20 mm cannons

The true acceleration power of the plane is only achieved very late into the grind. Specifically, the Tier 4 Engine injection modification provides a significant boost and is a top priority. On the way there, all engine upgrades should be taken. 13 mm belts are helpful for removing tracer rounds. The 20 mm gun pods with belts and the gun upgrade are viable choices but engine injection remains a priority.

Pros and cons

Pros:

  • Very powerful engine when using WEP, providing excellent acceleration and climb rate
  • Manual engine control can extend the climb rate and top speed in realistic and simulator battles
  • Nose mounted weaponry
  • Good performance at medium altitude
  • Good firepower for destroying larger attackers and bombers
  • Can carry additional armament
  • Performance on par with Griffon Spitfires (even better when fully upgraded)
  • 30 mm cannon will usually destroy anything that it hits
  • Can research nose-mounted 20 mm MG 151 cannon, which makes deflection shooting much more reliable
  • Exceptional high-speed manoeuvrability

Cons:

  • Low cannon ammunition count for the 30 mm MK 108 cannon and the 13 mm MG 131 machine guns
  • Low velocity 30 mm shell with a high drop, resulting in a VERY large lead angle on targets in turn leading to poor dogfight performance due to having to pull extreme turns to get guns on target
  • Flimsy airframe, prone to react heavily to damage
  • When aircraft is stock, very heavy and slow to fly without WEP
  • Stock 13 mm machine gun belts consist solely out of tracers which alerts enemy, makes aiming 30 mm difficult
  • Fighters with lower top speeds but better low altitude performances (such as Russia's La-7 fighters) will find it quite easy to run down the K-4 when at a low energy state
  • Very slow deploying flaps

History

The Bf 109 K-4 was one of Kurfurst Bf 109 series, Kurfurst was the last series of 109 before war's end. The K series was the most upgraded and most expensive 109 and with the war coming to an end not many were built. Work on the K series began in the spring of 1943 and prototype was ready by autumn of the same year. The series began production in August 1944 with the K-4 but due to changes to the design and delays with the new DB605D engine, the K-4 was the only one to be mass-produced. Externally, the Kurfurst series had changes in radio equipment location hatch. A filler point for the fuselage fuel tank, and with removal of the D/F loop, were the main external differences to other Bf109 series. The landing gear also had doors that closed up the bottom completely and armament was the Motorkanone 108 (30 mm) , 2 x MG 131 (13 mm), with additional 2 gun pods of MG 151 (20 mm). Payloads included a 500 kg bomb or on rare occasion Wfr.Gr.21 Rockets (21 cm). Due to limited resources, many of the variants didn't enter production.

Variants:

  • R I ETC 501/IX b or Schloß 503belly bomb rack, fusing equipment for fitting a 250 kg (550 lb) or 500 kg (1,100 lb) bomb
  • R III Schloß 503A-1 rack for one fuselage drop tank (300 L/80 US gal).
  • R IV BSK 16 gun-camera in the left-wing between nose ribs 3 and 4.
  • R VI two 20 mm Mauser MG 151/20 underwing gun pods with 135 RPG.
  • K-0 Pre-production aircraft, powered by a DB 605DM engine
  • K-2 proposed version without a pressurized cockpit
  • K-4 only serial production version without pressurized cockpit, powered by a DB 605DM (early on) or DB/DC engine
  • K-6 proposed heavy fighter version, as K-4 with reinforced wings holding two additional 30 mm MK 108 cannons and additional armour
  • K-8 proposed reconnaissance version, equipment similar to G-8
  • K-10 proposed version, similar to K-6, MK 103 M engine cannon instead of MK 108
  • K-12 proposed version, dual-seat trainer similar to G-12
  • K-14 proposed version, similar to K-6, powered by a DB 605L engine
