This is a list of variants of the Focke-Wulf Fw 190, with detailed descriptions.
The first prototype, the Fw 190 V1 (civil registration D-OPZE), powered by a 1,550 PS (1,529 hp, 1,140 kW) BMW 139 14-cylinder two-row radial engine, first flew on 1 June 1939. It soon showed exceptional qualities for such a comparatively small aircraft, with excellent handling, good visibility and speed (initially around 610 km/h (380 mph)). The roll rate was 162° per second at 410 km/h (255 mph), but the aircraft had a high stall speed of 205 km/h (127 mph).
The cockpit, located directly behind the engine, quickly became uncomfortably hot. During the first flight, the temperature reached 55 °C (131 °F), after which Focke Wulf's chief test pilot, Hans Sander commented, "It was like sitting with both feet in the fireplace." Flight tests soon showed that the expected benefits of Tank's cooling design did not materialize, so after the first few flights, this arrangement was replaced by a smaller, more conventional spinner that covered only the hub of the three-blade VDM propeller.
In an attempt to increase airflow over the tightly cowled engine, a 10-blade fan was fitted at the front opening of the redesigned cowling and was geared to be driven at 3.12 times faster than the propeller shaft's speed. This quickly became standard on the Fw 190 and nearly all other German aircraft powered by the BMW 801. In this form the V1 first flew on 1 December 1939, having been repainted with the Luftwaffe's Balkenkreuz and with the Stammkennzeichen (factory code) RM+CA.
The Fw 190 V2, designated with the Stammkennzeichen alphabetic ID code of FL+OZ (later RM+CB) first flew on 31 October 1939 and was equipped from the outset with the new spinner and cooling fan. It was armed with one Rheinmetall-Borsig 7.92 mm (.312 in) MG 17 machine gun and one 13 mm (.51 in) synchronized MG 131 machine gun in each wing root.
Even before the first flight of the Fw 190 V1, BMW was bench testing a larger, more powerful 14-cylinder two-row radial engine, the BMW 801. This engine introduced a pioneering example of an engine management system called the Kommandogerät (command-device): in effect, an electro-mechanical computer which set mixture, propeller pitch (for the constant speed propeller), boost, and magneto timing. This reduced the pilot's work load to moving the throttle control only, with the rest of the associated inputs handled by the Kommandogerät. The drawback was slight and minor surges that made the Fw 190 harder to fly in close formations. Tank asserted the device did not work well.
