MK-8 Spitfire
The "Spitfire" is the most renowned British aircraft of WWII. This iconic fighter plane played a pivotal role in the air defense of the British isles against the German Luftwaffe.
Most notably, they are credited with the Allied victory in the Battle of Britain, a major campaign fought entirely through the use of aircraft, in which the Nazi regime sought to destroy British infrastructure and air capabilities through the large scale use of fighters and bombers. The incredible engineering of the Spitfire yielded, in 1935, around "1,000-horsepower", through a "12-cylinder, liquid-cooled Rolls-Royce PV-12 engine," thanks to which "It had superb performance and flight characteristics", (Britannica). This model was later upgraded to the MK-8 "Supermarine", with even greater capabilities of speed and firing power. As can be seen, the Spitfires, along with the Hawker Hurricane, were used bravely and viciously by the Royal Air Force servicemen to prevent the Luftwaffe from securing its tactical objectives in the Battle of Britain, which can be considered Nazi Germany's first significant loss in the war.
