The Su-25 has a conventional aerodynamic layout with a shoulder-mounted trapezoidal wing and a traditional tailplane and rudder. Several metals are used in the construction of the airframe: 60% aluminium, 19% steel, 13.5% titanium, 2% magnesium alloy and 5.5% other materials.
All versions of the Su-25 have a metal cantilever wing, of moderate sweep, high aspect ratio and equipped with high-lift devices. The wing consists of two cantilever sections attached to a central torsion box, forming a single unit with the fuselage. The air brakes are housed in fairings at the tip of each wing. Each wing has five hardpoints for weapons carriage, with the attachment points mounted on load-bearing ribs and spars. Each wing also features a five-section leading edge slat, a two-section flap and an aileron.
The flaps are mounted by steel sliders and rollers, attached to brackets on the rear spar. The trapezoidal ailerons are near the wingtips. The fuselage of the Su-25 has an ellipsoidal section and is of semi-monocoque, stressed-skin construction, arranged as a longitudinal load-bearing framework of longerons, beams and stringers, with a transverse load-bearing assembly of frames. The one-piece horizontal tailplane is attached to the load-bearing frame at two mounting points

In February 2017, it was announced that Russia's United Aircraft Corporation had signed a contract with its subsidiary Ilyushin Aviation Complex for the development of a new version of Ilyushin Il-96-400 wide-body passenger airliner to compete with the Boeing 777-9 and Airbus A350-1000.
By January 2020, the first test-flight airframe was in final assembly and the wing and fuselage were joined, to be finished at the end of 2020 before a first flight in 2021
Projected double-deck version of Il-96 for 550-600 passengers and powered by Kuznetsov NK-93 propfan engines. Following flight tests in 2007 the engines were removed and the aircraft was not developed further.
