The wings are high-mounted and back-tapered with straight trailing edges. There are pods mounted at the square tips. There are two turbojets mounted alongside the body under the wings. There are semicircular air intakes forward of the wings’ leading edges. There are exhausts to the rear of the wings’ trailing edges. The fuselage is long, and slender and has a rounded nose. The body tapers to the rear section that overhangs the exhausts. There is a stepped canopy. The tail is swept-back and fin is tapered with a square tip. The flats mid-mounted on the fuselage, unequally tapered with blunt tips.
The Su-39 (also known as the Su-25T or Su-25TM) is a Frogfoot variant incorporating post-Afghanistan lessons-learned. It is based on the Su-25UB two-seat trainder, with the rear seat and cockpit replaced with a fuel cell and extra avionics. The Su-39 carries the Kopyo-25 multi mode radar in a pod under the fuselage. Armament includes ground attack missiles such as the AT-16 Vikhr , anti-ship missiles, and AAMs such as the R-27, R-27ER, R-60, R-73 and R-77. A four-fold reduction in thermal signature has been achieved through cooling intakes on the upper surface of aircraft, and a new center body which masks hot turbine blades. Only a few dozen of these aircraft have been built. Reports in the mid-1990s that the Su-39 designation had been assigned to a primary trainer derived from the Su-26 and Su-29 aerobatic competition aircraft, designed to replace the Yak-52, are apparently incorrect.
