This Russia’s Stealth Drone Is a Big Problem for NATO. The Sukhoi S-70 Okhotnik-B, Russian for “Hunter-B,” is an upcoming sixth-generation heavy stealth drone that will fly alongside the Su-57. The Okhotnik-B boasts a flying wing design, a take-off weight of around twenty tons, a maximum speed of around one thousand kilometers per hour, and an operational range of six thousand kilometers. The drone is believed to be powered by either the older AL-31F engine or the more advanced AL-41F engine that is also used by the Su-35S air superiority fighter.
