 Slats were fitted on the leading edges and slotted flaps were mounted on the trailing edges of the wings.The two Tumansky R-11 turbojet engines, initially with 57 kN (12,795 lbf) thrust each, were mounted in pods, similar to the previous Yak-25.The wing-mounted engines and bicycle-type main landing gear (supplemented by outrigger wheels in fairings near the wingtips) were widely spaced, allowing most of the fuselage to be used for fuel and equipment.
