The Focke-Wulf 187 was a twin-engined fighter developed in Germany before WWII. Its first flight was in 1937. For its time, it had outstanding performance, with a speed 80 Km/h faster than the Messerschmitt Bf109B as well as twice its range and better climb performance. However, in spite of this performance it did not fit into the tactical concept of the Luftwaffe and only a small series was built that was used for various tests and in a local defence squadron guarding the Focke-Wulf factory in Bremen
