A new Russian stealth drone has been reportedly photographed in detail for what may be the first time in Siberia.

Military analysts said first grainy images of Okhotnik, an unmanned combat air vehicle (UCAV) built by the Sukhoi design bureau, may have appeared online as early as 2017. On Wednesday, the U.S. aviation online outlet The War Zone reported that new photos of Okhotnik taken at a distance may have been snapped during November ground tests in Novosibirsk. The sixth-generation battle drone underwent tests last summer and is expected to fly for the first time in 2019, Interfax reported last June, citing an unnamed source.
