Spitfire at War

The most famous aircraft ever to serve in the Royal Air force. Never before and rarely since, has an airframe design been so successfully, continuously, aggressively and thoroughly developed. At the end of its development life, the Spitfire carried an engine giving more than twice the power and weighing about three-quarters more than the original, had its maximum speed increased by a quarter, its rate of climb almost doubled and its fire-power increased by a factor of five.
