The modernization and equipping of aircraft with modern systems is becoming an important field of activity of Military Aviation Works No. 2. The Company has upgraded MiG-29, Su-22, TS-11, Mi-17, Mi-8 and Mi-2 aircraft by equipping them with the following systems: GPS, TACAN, VOR/ILS, anti-collision lights, UHF/VHF radio stations, transponders, KT/IFF and more. In 2007 a thorough modernisation of Su-22 aircraft was carried out for the Angolan Air Force, including installation and integration of a new mission computer, EGI laser platform, HUD, and multifunction display. In the years 2011-2014 the Company overhauled 16 MiG-29 aircraft of the Polish Air Force. It involved integrating modern avionics systems and developing an open architecture based on the new mission computer and MIL BUS 1553 B.

In November 2011, a prototype refit of Mi-8 helicopter was completed, along with the extension of service life and modernization. The Company has been authorised to perform serial refits of this type of aircraft.

Since 2015, verification refits of Su-22M4K and Su-22UM3K aircraft have been carried out, including the adaptation of instruments in the cabin to English units and installation of a new radio station.

The verification overhaul extends the aircraft service life for another 10 years.
