Delta-Wing Dragon: Story of The SAAB J35-Sweden's Mach 2 Delta

摘要

The Draken (Dragon) concept dates back to September 1949 when the Swedish Air Force requisitioned a new single-seat all-weather interceptor to replace the Saab J29 'Tunnan', The program was named Project 1200 and called for a supersonic aircraft capable of achieving speeds of at least Mach 1.4 yet would be able to operate off specially-built sections of public roadway. It had to be ragged, easy to maintain, and cheap to operate as well. One of the most important requirements was that it had to have a , very high rate of climb in order to catch the emerg-ing threat of fast, high-altitude jet bombers traveling at speeds of Mach .9. Sweden was a neutral country and was determined to defend its inde-pendence against any threat, especially that of Cold War bombers from the Soviet Union.
