How Britain’s Hispano Mk.II 20mm Cannon Fired 600 RPM Without Jamming
The German Luftwaffe believed British 20mm aircraft cannons were unreliable and would jam during dogfights. But the RAF proved them wrong with the Hispano Mk.II — a powerful, high-rate-of-fire 20mm cannon that became one of the most reliable weapons of World War II.
This video explores how the Hispano Mk.II fired an incredible 600 rounds per minute, why it rarely jammed, and how it transformed RAF fighters like the Spitfire and Hawker Hurricane. Learn the engineering upgrades, battlefield performance, and real pilot accounts that show how this cannon helped the RAF dominate air combat.
Perfect for fans of aviation history, WWII technology, aircraft weapons, and military engineering.
