MOSCOW, April 7. /TASS-DEFENSE/. The cockpit glass of a Su-57 fighter jet can sustain a collision with a 1.8-kg object at a speed of 600 km/h, Rostec said: “The stealth glass survives a hit by a wrench and a collision with a 1.8-kg object at a speed of over 600 km/h. The characteristics were confirmed by trials with a pneumatic gun”.

The stealth glass was designed by Technologia Company in Obninsk. The material is extremely durable. Rostec released a video of the trials.

The corporation said the glass decreases the aircraft signature due to thin metal film and oxide coating by magnetron sputtering in a vacuum unit. The upgraded unit increased peak parameters of magnetron sputtering three times and coats the glass with lower surface resistance. The cockpit of the aircraft receives better optical characteristics and a lower radar signature.
