The M2 Browning (12.7 mm) is an aircraft-mounted heavy machine gun featured ubiquitously on American aircraft before, during, and just after WWII as forward-facing offensive armament, or as flexible defensive armament. It is related to the [[M2HB (12.7 mm)]] heavy machine gun which were heavier variants mounted to ground vehicles. The M2 Browning is commonly referred to as the ".50 cal", in relation to its ammunition's caliber.

There are 4 version of the M2 Browning in War Thunder. The "early" M2 does not have API bullets. The "mid" M2 is identical to the early M2, but with access to API bullets. The "late" M2 has access to more effective belts, has better accuracy, overheats slower, and a slightly higher rate of fire. The British have their own variant that is similar to the "mid" version but with different bullets (for example the API for the American gun is different from the British API).

In 1917, Germany introduced a new biplane called the Junkers J.I., which was one of the first armoured aircraft. This innovation made the rifle calibre machine guns used to arm biplanes at the time almost obsolete. General John J. Pershing, commander of the American Expeditionary Force, asked for a machine gun with a .50 inch calibre and a muzzle velocity of 2,700 feet per second to combat the new aircraft. That July, legendary gunsmith John Moses Browning began development of a larger version of the M1917 Browning design already used by the AEF to fit this criteria. The war ended during the development, but the project continued with Winchester making a .50 calibre round and muzzle velocity of 2,750 ft/s (838 m/s) in 1918 while Browning's new water-cooled machine gun for this new cartridge was finished in 1921. The Browning M1921 would be used experimentally until the design was upgraded in between 1927 to 1932 by S. H. Green and yielded seven different variants on the same receiver design, but with differences in the feed system and barrel or other components. The Army and Navy would accept a 60-pound "light version" for use on aircraft designated the .50 calibre AN/M2. American autocannon development suffered from unreliability issues, resulting in the M2 Browning becoming the main armament for aircraft with multiple machine guns being mounted in the wings or engine blocks to compensate for the lack of cannon shells with sheer volume of .50 calibre rounds. During World War II, it was the primary weapon of almost every pursuit fighter replacing the older [[Browning (7.62 mm)|Browning .30 M1919]]. It would also be used in fixed mounts in bombers ranging from the [[SBD-3]] Dauntless to the [[A-26 (Family)|A-26 Invader]] which had variants with 16 or 18 machine guns including the nose guns, mounted gun pods, and the dorsal turret for strafing attacks. It was also used in flexible mounts on bombers ranging from the [[B-17 (Family)|B-17 Flying Fortress]], the [[P-61A-1]] Black Widow, [[PBY-5 Catalina]] flying boats and the [[B-29A-BN]] Superfortress. After World War II, the dawning jet age led to the realization that the M2 did not have the rate of fire to deal with new generation fighters so they worked on making improved, faster firing variants of the M2 leading to the [[M3 Browning (12.7 mm)|M3 Browning]] which still sees service on some helicopters to this day. The M2 also sees use in the ground role with the [[M2HB (12.7 mm)|M2HB]] and the [[AN-M2 (12.7 mm)|AN-M2]] used by the Navy.

This page is about the aircraft-mounted M2 Browning (12.7 mm). For the vehicle-mounted variant, see M2HB (12.7 mm). For other uses, see M2 (Disambiguation).

Description

The M2 Browning (12.7 mm) is an aircraft-mounted heavy machine gun featured ubiquitously on American aircraft before, during, and just after WWII as forward-facing offensive armament, or as flexible defensive armament. It is related to the M2HB (12.7 mm) heavy machine gun which were heavier variants mounted to ground vehicles. The M2 Browning is commonly referred to as the ".50 cal", in relation to its ammunition's caliber.

There are 4 version of the M2 Browning in War Thunder. The "early" M2 does not have API bullets. The "mid" M2 is identical to the early M2, but with access to API bullets. The "late" M2 has access to more effective belts, has better accuracy, overheats slower, and a slightly higher rate of fire. The British have their own variant that is similar to the "mid" version but with different bullets (for example the API for the American gun is different from the British API).

The turreted variants of the M2 Browning are also separated into the "mid" version, the "late" version, and the British version. The only difference between the "mid" and "late" variants are the belt composition. The British version yet again has different bullets, but is otherwise identical to the American versions.

The DGP-1 gunpods are composed of 4 "late" M2's.

General info

The 12.7 mm (.50 cal) M2 Browning is a very powerful heavy machine gun when used in large numbers, particularly with the late P-51s and P-47s, with six and eight .50 cal machine guns respectively. However, on early American aircraft, many are armed with only a 7.62 mm and .50 cal, putting out very limited firepower. The .50 cals are inadequate in few numbers, making them ineffective in "snapshots" or high deflection shots. This is particularly noticeable in Spitfire Mk IX, XIV, and XVI, where the two Brownings provide insufficient firepower and are mounted too far apart, leaving only the plane with 2 cannons, with only 240-260 shells each, without complementing firepower. Without the cannons, the .50s can only chip away at the enemy, and the best hope for scoring is to hope for a lucky pilot snipe.

Comparison with analogues

The 12.7 mm M2 Browning is comparable in damage and or rate of fire to other contemporary heavy-calibre machine guns such as the Soviet Berezin UB (12.7 mm), German MG 151 (15 mm) and MG 131 (13 mm), Swedish Akan m/39A (13.2 mm) and Akan m/39A (12.7 mm) (based on the Browning M2), Italian Breda-SAFAT (12.7 mm), and Japanese Ho-103 (12.7 mm). The 12.7 mm M2 Browning is also comparable in damage to some early 20 mm such as the MG-FF or MG C30/L.

The 12.7 mm M3 Browning, being a development of the M2 Browning for jet aircraft, features similar ballistic performance with a faster fire-rate.

Usage in battles

  • AP, API, and API-T rounds are effective against light pillboxes, light tanks, armoured trucks, SPGs, artillery, AAA.
  • Usually incapable of an instant kill or a "snapshot" kill unless you pilot snipe, but is quite capable of a "snapshot fire" (not guaranteed though)... which is almost a kill...
  • Incredible range (can hit and still light a fire at 1.5km+, but damage does drop off). Good for long range desperation/harassment shots.

Pros and cons

Pros:

  • Usually carries enough rounds per gun to be able to take out multiple targets per sortie
  • Quite accurate, does not randomly spread a lot (unlike stock AN/M3 and stock Hispanos)
  • API-T rounds are exceptionally good at igniting fuel tanks and engines
  • Armour piercing (AP) rounds have better penetration values when compared to most small calibre cannons
  • Retains kinetic energy and damage potential over a range much better than 7 mm calibre machine guns
  • Can be fired accurately and be a significant threat to fleeing enemies upwards of 1.5 km away
  • Virtually only jams if you try to mag-dump (continuous fire until the weapon jams or runs out of ammunition) the entire ammo load
  • Makes up the bulk of the USAAF's armament with most planes utilizing anywhere between 4-8 guns

Cons:

  • Ball ammo in the default belt is rather ineffective
  • 25% slower rate of fire compared to 7 mm calibre machine guns
  • AP ammo lacks any incendiary or tracer, meaning shots that don't hit vital components barely does anything
  • Slower rate of fire at higher ranks means boom-n-zoom is necessary to maintain a firing solution long enough to dump sufficient rounds on target
  • The M2 Browning has 3 different variations, which all have vastly different ammunition belt types and how they are used

Words of wisdom: Always check the belt composition on a new vehicle or when returning to an old aircraft you have not used in a while...before heading into battle!

History

In 1917 during WWI, Germany introduced a new biplane called the Junkers J.I., which was one of the first armoured aircraft. This innovation made the rifle calibre machine guns used to arm biplanes at the time almost obsolete. General John J. Pershing, commander of the American Expeditionary Force (AEF), asked for a machine gun with a .50 inch calibre and a muzzle velocity of 2,700 feet per second in order to combat the new aircraft. That July, legendary gunsmith John Moses Browning began development of a larger version of the M1917 Browning design already used by the AEF to fit this criteria. The war ended during the development, but the project continued with Winchester making a .50 calibre round and muzzle velocity of 2,750 ft/s (838 m/s) in 1918 while Browning's new water-cooled machine gun for this new cartridge was finished in 1921.

The Browning M1921 would be used experimentally until the design was upgraded in between 1927 to 1932 by S. H. Green and yielded seven different variants on the same receiver design, but with differences in the feed system, barrel, and other components. The Army and Navy would accept a 60-pound "light version" for use on aircraft designated the .50 calibre AN/M2. American autocannon development suffered from unreliability issues, resulting in the M2 Browning becoming the main armament for aircraft with multiple machine guns being mounted in the wings or engine blocks to compensate for the lack of cannon shells with a sheer volume of .50 calibre rounds.

During World War II, it was the primary weapon of almost every pursuit fighter, replacing the older Browning .30 cal M1919. It would also be used in fixed mounts in bombers ranging from the SBD-3 Dauntless to the A-26 Invader which had variants fitted with up to 16 or 18 machine guns including the nose guns, mounted gun pods, and the dorsal turret for strafing attacks. It was also used in flexible mounts on bombers ranging from the B-17 Flying Fortress, the PBJ-1J, PBY-5 Catalina flying boats and the B-29A-BN Superfortress.

After World War II, the dawning jet age led to the realization that the M2 did not have the rate of fire to deal with new generation fighters so they worked on making improved, faster firing variants of the M2. This lead to the M3 Browning which saw service in the jet era and still sees service mounted on some helicopters to this day.

The M2 design also sees use in the ground role in the M2HB and naval use with the AN-M2.
