The Sukhoi Su-1, which first flew in 1940, represents early Soviet fighter development. This single-seat, single-engine aircraft measures 8.4 meters long with an 11.5-meter wingspan, achieving 640 km/h with a 720-kilometer range. Designated as a high-altitude fighter, the Su-1 addressed Soviet requirements for intercepting German bombers at elevation. Its modest dimensions and available powerplant reflect Soviet manufacturing capabilities during wartime aircraft development. The Su-1 served transitional role in Soviet fighter evolution from biplane toward monoplane dominance.
