From the manufacturer:
The Boeing B-17 "Flying Fortress" boasts a remarkable legacy, as both a strategic weapon and an enduring symbol of AMerican air power during WWII. Designed as a large, multi-engine bomber with substantial defensive armament, the B-17 was introduced in 1938. First used in combat with the RAF in 1941, where it carried out bombing raids in France, its poor performance suggested that improved defense and greater bombing accuracy were needed if the B-17 was to ever be a success.
Later variants like the B-17G proved more effective and it gradually became a potent strategic weapon capable of carrying out high-altitude, long-range attacks. Despite heavy defensive armament, the B-17s still suffered at the hands of enemy fighters and it was only with the advent of long-range escort fighters that the losses became acceptable.
Completed model measures 320mm long and 438 wide.
