The Spitfire Mk. XIV was the first of the Griffon-powered Spitfires to be powered by the Griffon 65 inline engine, which was fitted with a two-stage supercharger to overcome the poor high-altitude performance of the earlier, single-stage Griffon engines. At maximum power, this new engine model could produce 2,050 horsepower. In addition to the new engine, a new five-bladed Rotol propeller was also fitted to the plane.

The initial armament of the Mk. XIV consisted of 0.303 Browning light machine guns and 20 mm Hispano Mk. II cannons fitted in the wings. Later, during the summer of 1944, the 0.303s were replaced with a pair of Browning M2 0.50 caliber heavy machine guns. To gain extra performance while chasing V-1 flying bombs in the summer of 1944, some squadrons removed the machine guns and faired over the firing ports. A lead-computing gyroscopic gunsight could also be fitted.

The Spitfire Mk. XIV could be fitted with bomb racks to carry 250 lb. and 500 lb. bombs, although operationally this was limited to one squadron from February 1945. To improve turning performance, Mk. XIVs began being fitted with clipped wingtips in the winter of 1944-45.

Production of the Spitfire Mk. XIV began in late 1943, and the first handful of planes was issued to No. 610 Squadron at the end of December 1943. Besides hunting for V-1s, this model of the Spitfire eventually became the 2nd Tactical Air Force’s main high-altitude air superiority fighter over northwestern Europe. Mk. XIVs began to be sent to southeastern Asia in June 1945, but these saw no usage against the Japanese.All told, 957 Mk. XIV Spitfires were built. After the end of World War II, the plane was exported to a number of foreign countries, including Belgium, India, and Thailand.

In addition to Quick Mission Builder, Advanced Quick Mission Generator and Multiplayer modes, you can fly it in Career mode during Battle of Normandy and Battle of Bodenplatte timeframes.

Operation features

• The engine is equipped with the automatic governor of the manifold pressure that works when the throttle is set to 1/3 position or above.
  
• The engine has a two stage mechanical supercharger which does not require manual control. It can be switched to the low gear manually.
  
• The engine is equipped with an automatic fuel mixture control which maintains optimal mixture.
  
• Engine RPM has an automatic governor that controls the propeller pitch to maintain the required RPM.
  
• The water and oil radiators shutters are operated automatically, but there is a special manual mode that forces radiator shutters to open completely.
  
• The aircraft has a neutral static stability. The elevator effectiveness is high, so the aircraft should be controlled carefully, not giving too much flight stick input.
  
• The aircraft becomes unstable with extended landing flaps.
  
• The aircraft is equipped with elevator and rudder trimmers.
  
• Landing flaps have a pneumatic actuator so they can be extended to maximum position only. Speed with extended landing flaps is limited to 160 mph.
  
• The tail wheel rotates freely and does not have a lock. Since the landing gear wheels are relatively close to each other, it is necessary to confidently and accurately operate the rudder pedals during the takeoff and landing.
  
• The aircraft has differential pneumatic wheel brakes with shared control lever. This means that if the brake lever is held and the rudder pedal the opposite wheel brake is gradually released causing the plane to swing to one side or the other.
  
• The aircraft is equipped with a siren that warns a pilot if the throttle is set to low position with landing gear retracted.
  
• It is impossible to open or close the canopy at high speed due to strong airflow. The canopy has an emergency release system for bailouts.
  
• The aircraft is equipped with two underwing formation lights.
  
• Standard gunsight is adjustable: both the target distance and target base can be set.
  
• The gyroscopic gunsight automatically calculates required angular deflection while firing at a target. It has 4 modes: fixed reticle, fixed and gyro reticle, gyro reticle, gyro reticle with the target range fixed at 150 yards (night mode). The angular deflection will be calculated correctly only if the target range is set properly. To set the range, adjust the target base first using separate controls and then set the range by adjusting the size of the range finding reticle to be the same as the target size.
  
• Both gunsights have sliding sun-filters.
