Supermarine Spitfire Mk.IX (1942)

The Supermarine Spitfire Mk.IX, a British single-engine fighter from World War II, represents a major upgrade of the Mk.V airframe designed to accommodate the powerful 1,565 hp Rolls-Royce Merlin 61 two-stage engine, created to effectively counter the German Fw 190. The aircraft features an all-metal, cantilever low-wing configuration with a distinctive elliptical wing—spanning 11.23 m with an area of ​​22.48 m²—and a thin airfoil profile. Its semi-monocoque fuselage is 9.12 m long, with a normal takeoff weight of approximately 3,400 kg. A liquid-cooled, 12-cylinder V-engine in the nose drives a four-bladed, variable-pitch Rotol propeller, while two enlarged radiators are symmetrically mounted beneath the wings. The "C-type" wing is armed with two 20mm Hispano Mk II automatic cannons (120 rounds per barrel) and four 7.7mm Browning machine guns (350 rounds each); the weapons are housed within the wing sections, with their barrels extending beyond the leading edge. The cockpit, located in the mid-fuselage, features a sliding bubble canopy, bulletproof windscreen, armored seat back, a suite of analog flight and navigation instruments, and an optical gunsight. The fuel system utilizes self-sealing tanks located in the fuselage forward of the cockpit. The main landing gear retracts outward—from the fuselage sides toward the wingtips—into dedicated wheel wells, while the tailwheel is fixed. Thanks to its optimized aerodynamics and high power-to-weight ratio, the Spitfire Mk.IX reaches speeds of up to 654 km/h at altitude and boasts exceptional climb rate and maneuverability.
