Soviet Su-25 attack aircraft are obsolete for participation in modern wars, and Russia, for economic reasons, could not modernize them to the more advanced Su-39. This is written by the Chinese edition of Sina.com.
The aircraft is equipped with electronic equipment and missile attack warning systems that do not meet modern realities, so the slow Su-25 is vulnerable to attacks of almost any MANPADS, the publication notes.
According to the authors of the material, instead of aircraft like the Su-25, it is more expedient to use reconnaissance and strike flying drones, for example, Chinese Rainbow CH-4 or American MQ-9 Reaper.
The Soviet subsonic Su-25 first took off in 1975. Currently, the Su-25 is being replaced with the Su-34, the first flight of which took place in 1990. In February 2018, the Su-25 of the Russian military aviation space in Syria was hit by MANPADS of militants. Pilot attack aircraft Roman Filipov catapulted, but undermined himself with a grenade, so as not to be captured. The pilot is presented to the title of Hero of Russia.
