The Su-9 was developed from earlier work on a developmental aircraft designated T-3, to which the Su-9 was nearly identical. Internally at Sukhoi, the Su-9 was known as the T-43. The delta wing of the Su-9 was adopted because of its lower drag in the supersonic flight regime.
The aircraft carried a total of 1,350 kilograms (2,980 lb) of fuel in two bladder tanks, one each ahead and behind the pilot. The low-mounted, straight wing had a single-spar and a slight dihedral of 4°20'. The outer flaps were split and could act as air brakes. The Su-9 was the first Soviet aircraft to use hydraulic-powered controls. [3]
