The crashed Russian Su-57 was found to have at least four critical problems, learned BulgarianMiltary.com, according published report in Military Review of some russian experts, Eurasia Diary reports citing Bulgarian Military.

The crash involving a fifth-generation Russian fighter in the Khabarovsk Territory made it possible to establish that this combat aircraft was absolutely not even ready to fly, not to mention the fact that one of the features of the fighter, which gave it an advantage in aerial combat, was unexpectedly lost.

As part of the review of all versions of the crash, it was possible to identify at least three critical problems of the Russian Su-57, three of which were quite enough for the plane to crash.

“Among the main problems inherent in the new machine, experts single out, firstly, the use of new control systems. <…> The second possible problem is related to the tail. On the Su-57, it is represented by all-turning trapezoidal stabilizers, includes keels with small air intakes that allow cooling aircraft equipment <…> In addition to the listed problems that could lead to the crash of the car, the Su-57 has other obvious disadvantages. For example, many experts talk about problems with electronics, which is due, first of all, to the lack of domestic high-tech industries in Russia in Russia,” the Military Review Russian news publication reports.

Moreover, according to the publication, the fifth-generation Russian fighter has problems with stealth, which reduces the success of its use in battle, although until recently it was reported that the Su-57 is a “stealth” fighter.

Despite a lot of hegative comments and reports the Russian Deputy Prime Minister Yuri Borisov said that the program for the supply of fifth-generation Russian fighter aircraft Su-57 to the Armed Forces of the Russian Federation will continue in accordance with the schedule.

“Everything is going according to plan, everything is fine,” the Deputy Prime Minister said in response to a question from Interfax about a possible adjustment to the program after the crash of the Su-57 in the Khabarovsk Territory.

Earlier it was reported about the creation of a commission to investigate the causes of the crash of the Su-57.
