The first Su-57 Felon fighter appears to have been handed over to the Russian Ministry of Defense this month, with reports from spotters as the only confirmation.

A Russian military flight test center celebrated its 100th anniversary on Sept. 29 by publishing a video showing the flight of a group of four Su-57 fighters, one of which carried two R-77M medium-range air-to-air missiles that had not been seen before.

The most interesting unmanned aircraft system exhibits at Russia’s recent Army 2020 symposium were not the platforms themselves, but the new, dedicated weapons for them that were shown for the first time in large numbers.
