Germany produced around 3,300 D.VII aircraft in the second half of 1918. In service with the Luftstreitkräfte, the D.VII quickly proved itself to be a formidable aircraft. The Armistice ending the war specifically required Germany to surrender all D.VIIs to the Allies. Surviving aircraft saw continued widespread service with many other countries in the years after World War I. Fokker's factory was not up to the task of meeting all D.VII production orders. Idflieg therefore directed Albatros and AEG to build the D.VII under license, though AEG did not ultimately produce any aircraft. Because the Fokker factory did not use detailed plans as part of its production process, Fokker simply sent a completed D.VII airframe for Albatros to copy. Albatros paid Fokker a five percent royalty for every D.VII built under license. Albatros Flugzeugwerke and its subsidiary, Ostdeutsche Albatros Werke (OAW), built the D.VII at factories in Johannisthal (designated Fokker D.VII (Alb)) and Schneidemühl (Fokker D.VII (OAW)), respectively. Many sources erroneously state that the D.VII was equipped with the 120 kW (160 hp) Mercedes D.III engine. The Germans themselves used the generic D.III designation to describe later versions of that engine. The earliest production D.VIIs were equipped with 170-180 hp Mercedes D.IIIa. Production quickly switched to the intended standard engine, the higher-compression 134 kW (180-200 hp) Mercedes D.IIIaü. It appears that some early production D.VIIs delivered with the Mercedes D.IIIa were later re-engined with the D.IIIaü. By mid-1918, some D.VIIs received the "overcompressed" 138 kW (185 hp) BMW IIIa, the first product of the BMW firm. The BMW IIIa followed the SOHC, straight-six configuration of the Mercedes D.III, but incorporated several improvements. Increased displacement, higher compression, and an altitude-adjusting carburetor produced a marked increase in speed and climb rate at high altitude. Because the BMW IIIa was overcompressed, using full throttle at altitudes below 2,000 m (6,700 ft) risked premature detonation in the cylinders and damage to the engine. At low altitudes, full throttle could produce up to 179 kW (240 hp) for a short time. Fokker-built aircraft with the new BMW engine were designated D.VII(F), the suffix "F" standing for Max Friz, the engine's designer. BMW-engined aircraft entered service with Jasta 11 in late June 1918. Pilots clamored for the D.VII(F), of which about 750 were built. Production of the BMW IIIa was very limited and the D.VII continued to be produced with the 134 kW (180 hp) Mercedes D.IIIaü until the end of the war. D.VIIs flew with different propeller designs from different manufacturers. Despite the differing appearances there is no indication these propellers gave disparate performance. Axial, Wolff, Wotan, and Heine propellers have been noted. The D.VII entered squadron service with Jasta 10 in early May 1918. When the Fokker D.VII appeared on the Western Front in April 1918, Allied pilots at first underestimated the new fighter because of its squarish, ungainly appearance, but quickly revised their view. The type quickly proved to have many important advantages over the Albatros and Pfalz scouts. Unlike the Albatros scouts, the D.VII could dive without any fear of structural failure. The D.VII was also noted for its high maneuverability and ability to climb at high angles of attack, its remarkably docile stall, and its reluctance to spin. It could literally "hang on its prop" without stalling for brief periods of time, spraying enemy aircraft from below with machine gun fire. These handling characteristics contrasted with contemporary scouts such as the Camel and SPAD, which stalled sharply and spun vigorously. The D.VII also had problems. Several aircraft suffered rib failures and fabric shedding on the upper wing. Heat from the engine sometimes ignited phosphorus ammunition until cooling vents were installed in the engine cowling, and fuel tanks sometimes broke at the seams. Aircraft built by the Fokker factory at Schwerin were noted for their lower standard of workmanship and materials. Nevertheless, the D.VII proved to be a remarkably successful design, leading to the familiar aphorism that it could turn a mediocre pilot into a good one, and a good pilot into an ace. Manfred von Richthofen died days before the D.VII began to reach the Jagdstaffeln and never flew it in combat. Other pilots, including Erich Löwenhardt and Hermann Göring, quickly racked up victories and generally lauded the design. Aircraft availability was limited at first, but by July there were 407 on charge. Larger numbers became available by August, when D.VIIs achieved 565 victories. The D.VII eventually equipped 46 Jagdstaffeln. When the war ended in November, 775 D.VII aircraft were in service. The Allies confiscated large numbers of D.VII aircraft after the Armistice. The United States Army and Navy evaluated 142 captured examples. Several of these aircraft were re-engined with American-built Liberty L-6 motors, very similar in appearance to the D.VII's original German power plants. France, Great Britain, and Canada also received numbers of war prizes. Other countries used the D.VII operationally. The Polish deployed approximately 50 aircraft during the Polish-Soviet War, using them mainly for ground attack missions. The Hungarian Soviet Republic used a number of D.VIIs, both built by MAG and ex-German aircraft in the Hungarian-Romanian War of 1919. The Dutch, Swiss, and Belgian air forces also operated the D.VII. The aircraft proved so popular that Fokker completed and sold a large number of D.VII airframes that he had smuggled into the Netherlands after the Armistice. As late as 1929, the Alfred Comte company manufactured eight new D.VII airframes under license for the Swiss Fliegertruppe. RARE & HARD TO FIND IN THIS CONDITION. READY TO COMPLETE YOUR COLLECTION.
