The 20mm, a projectile that is larger than the .50 caliber, but intended for different purposes, was developed to fulfill that need. The early designs, like the Oerlikon cannons, saw significant service in the Second World War, primarily mounted on Allied ships. As the war progressed, 20mm cannons became invaluable as anti-aircraft guns on land and aboard naval vessels. This weapon quickly proved its mettle by quickly adapting to the changing landscape of aerial warfare. It also proved to be effective in the ground role during the war. These weapons systems were adopted by multiple forces, and were used in many theaters throughout the war.
These two distinct weapons systems emerged from similar environments – periods of intense technological advancement spurred by the demands of war. However, their development and primary roles reflect different strategic priorities, setting the stage for their respective evolutionary paths and eventual employment in diverse applications.
Inside the Machines: Exploring Design and Mechanics
Delving into the physical attributes and operational intricacies reveals the core differences between these powerful weapon systems.
The ammunition, the heart of any weapon, tells much of the tale. The .50 caliber fires the massive 12.7x99mm cartridge. The projectiles, typically weighing around 750 grains, offer a variety of options. Ball rounds provide standard function, while armor-piercing and incendiary variants expand its operational capabilities. The sheer size and weight of the .50 caliber round are indicative of its capacity for destruction.
The 20mm, on the other hand, utilizes a range of ammunition, tailored to specific roles. High-explosive (HE) rounds deliver devastating blast effects, while armor-piercing (AP) rounds penetrate hardened targets. Incendiary rounds add another layer of destructive force. The versatility of the 20mm ammunition is a significant advantage, allowing for adaptation to a wide range of engagements.
The .50 caliber machine gun often takes the form of the Browning M2, a weapon characterized by its recoil-operated design. The M2 uses a reciprocating bolt and is generally a very reliable design. The barrel can be changed in order to maintain a healthy firing rate. The .50 caliber weapon is typically larger and heavier, making it suitable for fixed positions or vehicle mounting.
The 20mm cannons utilize a more complex operating system. Gatling guns, single-barrel cannons, and chain guns are all commonly seen in the 20mm category. Many are electrically powered, which allows for high rates of fire. Their designs allow them to deliver devastating barrages of projectiles. These features make them a preferred weapon for aircraft, anti-aircraft defense, and specialized ground vehicles.
