The Reggiane Re.2005 "Sagittario" (Archer in English) was the result of many years of developing and refining the Re.2000 series of fighters. It was much faster than previous models thanks to its DB 605A engine and was more aerodynamically sleek. These changes helped propel the Re.2005 to speeds well over 640 km/h (397 mph). The elliptical wing, also seen in early Spitfires, gave the Re.2005 an incredible turn rate that could keep up with Spitfires. German pilots would also state that the Sagittario had similar flight characteristics to the Bf 109 G-14. The Re.2005 was a relatively good aircraft, but it would never be built in massive numbers. Only a handful were produced, and the armistice forced the destruction of some Re.2005s.

Introduced in Update 1.91 "Night Vision", the Re.2005 serie 0 is a decent Italian fighter. Although the performance was superb in real life, in-game it is outclassed by many aircraft due to its battle rating. Aircraft like the F8F Bearcat and Griffon-powered Spitfires will easily outrun the Sagittario. This is a common issue with planes that are more focused on the ability to turn than straight-line speed. Sagittario pilots should expect to be the victims of constant boom and zoom attacks; the best option is to perform reversals and try and get a shot off after the enemy aircraft makes a pass. Players can also sideclimb and wait for enemy aircraft to lose their altitude. Armed with three MG 151 cannons and two Breda-SAFAT 12.7 mm machine guns, the Re.2005 can easily down enemy aircraft with the air target belts. It also has plenty of ammunition, so players can be generous with firing. Overall, the Re.2005 is a relatively difficult aircraft to succeed in due to its battle rating.
