À propos de ce contenu

The SSW D.IV came very late to the Great War to change Germany’s fortunes, but what machines did make it to front-line squadrons acquitted themselves well. The SS.DIV was the end result of a robust line of aircraft that saw service in the war and it came with a unique feature. The 200-hp SH.IIIa rotary engine had a crankshaft that rotated opposite of the engine and the propeller ’s rotation in an attempt to reduce the torque. The four-bladed propeller gave it a fast rate of climb and a high speed. The SS.DIV was even faster than Germany’s mainstay front-line fighter, the very successful Fokker D.VII. It was also very maneuverable, but reportedly had nasty stall behavior when pushed too far. The SS.DIV was armed with two 2 × 7.92mm machine guns.

SSW D.IV is a completely new addition - it wasn't modeled in our earlier WWI sim Rise of Flight. It can be used in Quick Mission Builder, Advanced Quick Mission Generator and Multiplayer modes.
