Lla Fokker D.VII était un avion de chasse allemand de la Première Guerre mondiale conçu par Reinhold Platz du Fokker-Flugzeugwerke. L’Allemagne a produit environ 3 300 avions D.VII au second semestre de 1918. En service avec le Luftstreitkräfte, le D.VII s’est rapidement révélé être un avion redoutable. L’armistice mettant fin à la guerre exigeait expressément de l’Allemagne qu’elle rende toutes les D.VII aux Alliés. Les avions survivants ont connu beaucoup de service dans de nombreux pays dans les années qui ont après la Première Guerre mondiale.
Lla Fokker D.VIIis widely considered the finest fighter aircraft produced during World War I. Entering service in April 1918, it arrived just in time to restore German air superiority. It was so formidable that the Allied powers included a specific clause in the Armistice agreement (Article IV) demanding that Germany surrender every single D.VII in its inventory. It was noted for being exceptionally easy to fly, famously described as being able to « turn a mediocre pilot into a good one, and a good pilot into an ace. »

Revolutionary Engineering
Cantilever Wing Design:Unlike contemporary biplanes that relied on a complex web of external bracing wires, the D.VII used thick « cantilever » wings. This reduced aerodynamic drag significantly and made the wings incredibly strong, allowing the plane to dive at speeds that would have ripped the wings off other aircraft.
Welded Steel Tube Fuselage:While most aircraft of the era used wooden frames, Anthony Fokker utilized a frame of welded steel tubing. This made the aircraft more durable in combat and better at protecting the pilot during crash landings.
Lla « Propeller Hang »:The D.VII had a unique ability to « hang on its prop »—essentially flying at a nose-high angle in a near-stalled condition while remaining fully controllable. This allowed pilots to fire upward into the unprotected bellies of Allied aircraft.
BMW IIIa Engine:The later « F » variants were equipped with the high-compression BMW engine. This motor was designed to maintain power as the air thinned at high altitudes, giving the D.VII a massive advantage over Allied fighters like the Sopwith Camel.
A Legacy Smuggled into History
The Great Smuggle:After the war, Anthony Fokker successfully smuggled several trains full of D.VII components and engines across the border into his native Netherlands, defying the Armistice terms and allowing his company to continue production post-war.
Global Service:Because it was so advanced, the D.VII served for years after the war in the air forces of Poland, Belgium, the Netherlands, and even the United States, where captured examples were used for research.
The Red Baron’s Input:Manfred von Richthofen personally flew the prototype (the V.11) during the January 1918 fighter competition. His enthusiastic recommendation was a key reason the aircraft was rushed into mass production.
Preservation:Only about seven original D.VIIs survive today. One of the most famous is displayed at theMusée national de l’air et de l’espacein Washington, D.C., still wearing its original « lozenge » camouflage fabric.
