Developed by Hugo Junkers, the D-1 was the world's first operational all metal fighter plane. With a top speed of 140 mph and a service ceiling of just under 20,000 feet the D-1 was decades ahead of its wood and wire, fabric covered competition. This made it arguably the Messerschmitt ME-262 of World War One! Though it arrived too late to play a significant part, the Junkers D-1 was certainly a harbinger of what "Warbirds" were to become!                                                                                                                                                                                                                                                                               Upgrade To the Junkers D-1 Kit Package
