Russian fifth-generation Su-57 fighters have begun using new low-visibility missiles S-71K and S-71M. This was also reported by Ukrainian media. So far, there are only photos of the new ammunition. This is a hybrid of a drone and a S-71M Monochrome missile and low-visibility cruise missiles S-71K Carpet. The first mentions of the S-71 appeared in 2019. There is no information with characteristics on them, officially they are still undergoing tests, so far only assumptions are published. We publish patent images showing the operation of the S-71 drones. Judging by them, the drone launched from the aircraft will search for the line of combat contact and independently search for targets. The estimated range of the S-71 ammunition is up to 350 km, with a flight altitude of 5 to 75 meters. Flight speed from 730 to 950 km / h
