Adem Duygu, a military analyst from Turkey, posted commercial satellite imagery of Russia's new combat stealth drone on a flight line around the date President Vladimir Putin inspected the country's latest warplanes at the 929th Chkalov State Flight-Test Center in Russia's Astrakhan region.

Commenting on the latest satellite imagery, The National Interest said the new drone, dubbed the Sukhoi Okhotnik-B, or Hunter-B, a stealth heavy unmanned combat aerial vehicle (UCAV) being developed by Sukhoi as a sixth-generation aircraft, was first spotted by land-based cameras earlier this year at an airfield in Novosibirsk in southern Russia.

Duygu didn't provide a date on when the satellite imagery was taken, but it's likely the photo was snapped within the first two weeks of May. This is because, on May 14, Putin was escorted by six Sukhoi Su-57 stealth jets to Chkalov, for an immediate inspection of the flight line.

The satellite image of the flight line at the Chkalov State Flight-Test Center shows the Hunter-B, Su-57, Su-34, a MiG-29, and multiple Sukhoi Flanker variants.
