Throughout the 1920s and 1930s, the Luftwaffe (German Air Force) moved ahead at break-neck speeds to develope civilian aircraft which secretly doubled as military fighters and bombers requiring only minor modifications to become war-fighter operational. Aircraft designated as transport and airline variants could easily be converted to bombers and the initial Bf 109 was no different in its purposes. The birth of the Bf 109 started out as a requirement from Herman Göring, Reichsminister of Aviation proposed to newly appointed Theo Croneiß of Bayerisch Flugzeugwerke (BFW, Bavarian Aircraft Works). The requirement was for a single-seat high-speed courier plane, obviously, one which could be converted into a fighter when the time required. At the same time this requirement went out, the Reichsluftfahrtministerium’s (RLM, Reich Aviation Ministry) Technisches Amt (C-AMT) or technical department was tasked with projecting aircraft requirements for potential future air combat and of the four main types determined to be essential, single-seat fighter requirements were published as L.A. 1432/33.

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.

During the early years of BFW, Willy Messerschmitt was the designer of the transport aircraft the BFW M.20, however due to several high-profile crashes of these transport aircraft, one of which included test pilot Hans Hackmack, a close friend of Erhard Milch (at the time, head of Luft Hansa and the German civil aviation authorities). With Erhard Milch, a lifelong hatred developed when Messerschmitt responded very callously to events about the crash. During this time, BFW went bankrupt and Messerschmitt went to work designing aircraft for a Romanian airline company. At the time requirements for L.A. 1432/33 were published, Messerschmitt was called back to Berlin and basically told his efforts were to be used for the Fatherland. Messerschmitt acquiesced and was given the specifications for the potential fighter, which after review, he proceeded to relate a very unfavourable opinion of the fighter as if built as described, the fighter would be literally obsolete as it rolled off the assembly line and unable to catch up to even medium bombers. After hearing the report and seeing the truth in Messerschmitt's words, the Technisches Amt awarded BFW the contract to build a fighter aircraft and Willy Messerschmitt was given free rein over the design of the aircraft.
  
Variants:
+
Messerschmitt began design of the P.1034 (later known as Bf 109), and much like its older transport sibling the Bf 108, the new fighter was developed based on Messerschmitt’s lightweight construction principle, the basis of this principle was to minimize the number of separate parts located on the aircraft, which would speed up construction and add in ease of maintenance. For example, many of the main connection points for the airframe, engine frame and wings all had their connecting load points all at the firewall. Another example was having the landing gear attached to the fuselage and not the wings, which allowed for removal of the wings without having to support the aircraft on jack-stands and also reduced the stress on the wing loads during takeoff and landing. One tell-tale sign of a Bf 109 is the landing gear slightly splayed outwards and this was to increase the stability of the aircraft while taxiing on the ground by providing a wider track, making it less prone to flipping over.
  
* 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
+
Forethought was put into the aircraft especially for mechanics which would service the aircraft on the front-lines of battle. The entire engine cowling, weapon hatches, and other maintenance access panels could be removed allowing the mechanics full access to service, repair and even replace critical parts on the aircraft with little difficulty. Pipe connections were colour-coded and electrical cabling plugged into junction boxes, typically an old engine could be disconnected, removed, replaced with a new engine and all connections resecured in a matter of minutes, something unheard of in most military aircraft of the time.
* 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.
+
While a high-speed requirement would necessitate a small wing to decrease surface area, Messerschmitt knew this would require a more powerful engine to generate enough lift to maintain flight. The wings of the Bf 109 had several modifications which would compensate for these issues to include high-lift devices such as automatically-opening leading edge slats and trailing edge flaps which had a large camber to allow for a significant increase of lift when deployed. To help increase the overall flap effectiveness, the ailerons would also “droop” to aid in the flaps work. The weapons for the aircraft were all centrally located in the fuselage, with the large cannons mounted in the propeller hub and the machine guns located in the upper fuselage. Leaving these out of the wings allowed for significant manoeuvrability with all of the heavy equipment kept along the centerline of the aircraft leaving the wings to be very thin and light.  
* 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
+
Messerschmitt was ahead of his time, this was noted when the Bf 109 went to trials. Most experienced military pilots were seasoned World War I pilots who spent their time flying biplane fighters such as the He-51, aircraft with two sets of wings, open cockpit, low wing loading and light g-forces, one look at the new Bf 109 produced sour reactions, especially from stunt and ace pilot Ernst Udet. At first glance, Udet had serious doubts about the Bf 109 and requested directly from Messerschmitt to remove the canopy to allow the pilot to judge the aircraft’s speed through the air stream and to add a second wing with struts and wires, otherwise, the aircraft was destined to fail as a fighter. Udet’s initial test flight of the Bf 109 drastically changed his opinion of the revolutionary new fighter, forever changing how Germany designed and manufactured their fighters.  
* 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
+
Throughout the years, the Bf 109 with through many iterations involving upgrades and fine-tuning. The last of the series was the Bf 109 K series, also known as Kurfüst. Unfortunately for this series, it was a compilation of model upgrades, modification kits and factory conversions which ultimately made both the production and maintenance of this aircraft a literal nightmare in both cost and complication with its maintenance. Due to problems with the series production and the lateness of the war when it entered, the K-4 model was the only version to be mass-produced. External changes included movement of the radio equipment hatch, fuselage fuel tank filler point, movement of the direction-finding loop and a retractable tail-wheel with clam-shell doors. Armament would include a 30 mm motorkanon and 2 x 13 mm machineguns with options to attach bombs or 20 mm cannon gondola pods, however, the suspended armament was rarely utilised. Between November 1944 and March 1945, a total of 1,593 Bf 109 K-4 fighters were produced, one in four Bf 109s listed in front line fighting units was the Bf 109 K-4. Unfortunately at this point in the war, the Bf 109 K-4 had two things going against it, first was the appearance of jet fighters which nullified any advantages the K-4 had achieved and secondly, the hastily trained novice pilots at this point of the war could not exploit the K-4’s advantages which would eventually come from experience.
* 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

Description

GarageImage Bf109K4.jpg


The Bf 109 K-4 is a rank IV German fighter with a battle rating of 6.0 (AB), 5.7 (RB), and 6.3 (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.

Bf109 K-4 billythekid 001.png

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.

  • 60 mm bullet proof glass in front and rear of pilot
  • Fuel tank with 21 mm steel plate behind it, and 4 mm plates surrounding it
  • Pilot's seat has 4 mm steel plates underneath, with 8 mm steel making up the back rest
  • 10 mm steel plates surrounding rear bullet proof glass

Armaments

Offensive armament

Bf109 K-4 bomberpilot1784.png

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.

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

Throughout the 1920s and 1930s, the Luftwaffe (German Air Force) moved ahead at break-neck speeds to develope civilian aircraft which secretly doubled as military fighters and bombers requiring only minor modifications to become war-fighter operational.

These fighter requirements were as follows:

  • Top speed – 400 kph (250 mph) at 6,000 m (19,690 ft) maintained for 20 minutes
  • Total flight duration – 90 minutes
  • Critical altitude of 4,000 m reached within 17 minutes
  • Operational ceiling – 10,000 m (32,810 ft)
  • Armed with 1 x 20 mm motorkanone and two 7.92 mm machine guns
  • Rated performance in the order of: level speed, rate of climb and maneuverability

During the early years of BFW, Willy Messerschmitt was the designer of the transport aircraft the BFW M.20, however due to several high-profile crashes of these transport aircraft, one of which included test pilot Hans Hackmack, a close friend of Erhard Milch (at the time, head of Luft Hansa and the German civil aviation authorities). With Erhard Milch, a lifelong hatred developed when Messerschmitt responded very callously to events about the crash. During this time, BFW went bankrupt and Messerschmitt went to work designing aircraft for a Romanian airline company. At the time requirements for L.A. 1432/33 were published, Messerschmitt was called back to Berlin and basically told his efforts were to be used for the Fatherland. Messerschmitt acquiesced and was given the specifications for the potential fighter, which after review, he proceeded to relate a very unfavourable opinion of the fighter as if built as described, the fighter would be literally obsolete as it rolled off the assembly line and unable to catch up to even medium bombers.

Throughout the years, the Bf 109 with through many iterations involving upgrades and fine-tuning. The last of the series was the Bf 109 K series, also known as Kurfüst. Unfortunately for this series, it was a compilation of model upgrades, modification kits and factory conversions which ultimately made both the production and maintenance of this aircraft a literal nightmare in both cost and complication with its maintenance. Due to problems with the series production and the lateness of the war when it entered, the K-4 model was the only version to be mass-produced. External changes included movement of the radio equipment hatch, fuselage fuel tank filler point, movement of the direction-finding loop and a retractable tail-wheel with clam-shell doors. Armament would include a 30 mm motorkanon and 2 x 13 mm machineguns with options to attach bombs or 20 mm cannon gondola pods, however, the suspended armament was rarely utilised. Between November 1944 and March 1945, a total of 1,593 Bf 109 K-4 fighters were produced, one in four Bf 109s listed in front line fighting units was the Bf 109 K-4. Unfortunately at this point in the war, the Bf 109 K-4 had two things going against it, first was the appearance of jet fighters which nullified any advantages the K-4 had achieved and secondly, the hastily trained novice pilots at this point of the war could not exploit the K-4’s advantages which would eventually come from experience.

In-game description

The Messerschmitt Bf 109 was a single-seat monoplane fighter used by the Luftwaffe before and during WWII. It was used as a fighter, interceptor, high-altitude interceptor, fighter-bomber and reconnaissance aircraft.

The Bf 109K "Kurfuerst" was the last mass-produced variant of the Bf 109 family. It first reached front-line units in September 1944 (or early 1945, according to other data). The fighter was powered by the Daimler-Benz DB 605 DCM engine and had more powerful armament, with some variants equipped with two 15mm or three 30mm cannon.
