Up Close And Personal With The Browning .50 Caliber Machine Gun

 
 
SHARE:

The quest for automatic weaponry has been around since the invention of the gun itself, and war engineers have always tried their best to design weapons which require minimum reloading when being used in the field.

Research on such weapons gained momentum during the last two centuries, and WWI turned out to be the focal point during which several radical concepts & technologies were introduced to modern warfare.

One such development in the field of weaponry was the .50 Caliber Machine Gun that has carved its name through the 20th century to this very day. Here are our top facts about this mighty weapon.

Top Facts

The original name of the .50 Caliber Machine Gun is the M2 Browning. The prototype was developed by John M. Browning in 1918 right after WWI when the world was saying farewell to trench warfare.

The machine gun has been in production since 1921 and more than 3 million units have been produced to date, currently by a plethora of companies most notably General Dynamics, US Ordnance, Manroy Engineering UK, Sabre Defense, etc.

The M2 is transportable by a crew thanks to a back plate with a spade, trigger, grips and latch release. Furthermore, the gun comes with a flash suppressor and spare barrel assembly making it a portable machine gun compared to other heavy weapons.

The Machine Gun is almost 61.42 inches in length and weighs 84 pounds alone and 128 pounds with its tripod. The bore has a diameter of .50 inches, obviously!

The M2 Browning has an effective firing range of 1800 meters and a maximum range of 6800 meters. The fired bullet has a muzzle velocity of 809m/s!

The M2HB variant manufactured by General Dynamics has a cyclic rate of 450 – 600 rounds/minute. Faster variants include the AN/M3, for use in aircraft, having a rate of fire around 1200 rounds/minute.

Right from World War II to the Vietnam War, the M2 was used with armor piercing incendiary rounds. To be called armor piercing, bullets have to punch reliably through 22.2 mm of hardened steel armor from 500 meters.

If you were to make a 2-meter hole within a bunker using an M2 Browning, you would need 300 rounds. That’s $1500 at $5 per round!

It is stated time and again by US Army Personnel that, during battles, the sound of the M2 Machine gun forced any nearby infantry units to take cover!

The M2 has been used by the United States in almost all its conflicts since its production. The long list includes WW2, Korean War, Suez Crisis, Vietnam War, Iraq War, Invasion of Panama, Somali War, War in Afghanistan, etc.

As an anti-aircraft weapon on ships, as many as six M2 guns can be mounted on the same turret. While on the ground, the M2 is used in either twin or quadruple mode.

The AN/M2 and AN/M3 variants have been put to use on US pursuit aircraft like the P-51 Mustang, P-38 Lighting, P-40 Tomahawk, etc. during WW2 and F-80 Shooting Star, Thunderjet and Sabre in the Korean War. Other aircraft variants include XM213, GAU-15/A, GAU-21A, and M3P.

The M2 is even used as a sniper rifle when equipped with a telescopic sight. This was a common technique during the Korean & Vietnam Wars when such an aggressive weapon was combined with a sniper scope. The US Marine Corps sniper Carlos Hathcock is credited for the practical use of this technique as he used his M2 to take down targets over 1800 meters away, twice the range of an average sniper rifle of the time!

When the IRA used the .50 Caliber Machine Gun in Northern Ireland, the media gave the weapon worldwide notoriety as a gun for Snipers.

The Unit Replacement Cost of the standard M2 Machine gun is around $14,000.

The M2 Machine Gun is used by almost all countries which are not under an arms embargo from the US. M2HB is the most sold variant of the .50 Caliber Machine Gun.

During the design phase and initial prototype development, the power of the gun was so paramount that it was restricted to experimental use only right until 1937. Surely, the M2 Browning is one of the best machine guns ever.
