Concord is a copy of a Tu-144 - it flew 3 months after Soviet design.
The big differance though is the F-15 is a superior design in all respects with the one exception of overall top speed. When the US got our hands on the Mig-25 that flew to Japan we soon found out it was a POS. The F-15 wasn't designed to directly compete with the Mig-25 because it didn't need too. With well over 200 kills and NO losses in air to air combat the F-15 has proven itself. Can't really say that about the Mig-25 considering some of the kills made by the F-15 were Mig-25's. So much for being a "lame" copy huh?
Actualy design of the Concord started before the Tu-144. The Soviets rushed the Tu-144 program to beat the west and ended up with an aircraft with so many problem they shelved it, while the Concord went on to be a production aircraft that flew for over 20 years in international service with the best safety record of any comercial aircraft in history. Millions of miles flown and thousands of hours on the airframes and only 1 crash.
Oh and before you call the Concord a copy of the 144 you might want to look at some interesting facts concerning arrests that were made.
Although the Tu-144 flew before Concorde, its development was connected with industrial espionage against the French company Aérospatiale, which was developing Concorde. When Sergei Pavlov —officially acting as Aeroflot’s representative in Paris—was arrested in 1965, he was in possession of detailed plans of the braking system, the landing gear and the airframe of Concorde. Another agent named Sergei Fabiew, who was arrested in 1977, was believed to have obtained the entire plans of the prototype Concorde back in the mid-1960s. However, these were early development plans and would not have permitted the USSR engineers to come up with their own aircraft; the plans could only serve as a general indication of the work of the Concorde design team.
So who copied who???
