SPAD VII vs Albatros D III: 1917–18: Duel, cartea 36

When originally conceived, the French SPAD VII and German Albatros D II represented steps away from an emphasis on maneuver in aerial combat in favor of speed and durability - factors that came into play in hit-and-run tactics. At the end of 1916, however, Albatros tried to have the best of both worlds by incorporating the sesquiplane wing of the nimble Nieuport 17 into its D III. The result combined the better downward view and maneuverability of the Nieuport with the power and twin machine guns of the Albatros D II, but at a high price - a disturbing tendency for the single-spar lower wing to fail in a dive.

While Albatros (and the Austrian Oeffag firm, which built the fighter under license) sought to alleviate that weakness with various reinforcing measures, the Germans developed tactics to maximize the D III's strengths and minimize its shortcomings. At the same time, the French worked to improve the SPAD VII with more power and a more reliable cooling system before moving on to the twin-gunned SPAD XIII. While all that was going on, the Albatros D III became a mainstay of the German and Austro-Hungarian air services in frequent encounters with SPAD VIIs flown by French, Belgian, British, Italian and American airmen.
