An image of what was purported to be a prototype of Russia’s Okhotnik (Hunter) heavy unmanned aerial vehicle (UAV) began to circulate in Russian social media on 23 January, followed by three more images the next day.
The photos were likely taken by a plane spotter or spotters from close to the runway of Novosibirsk Aviation Plant (NAZ) named after V P Chkalov (part of the Sukhoi Company), also known as Yeltsovka airport.
The heavy UAV appearing in those images looks like a stealthy flying wing aircraft, although its conventional looking turbofan (likely of the AL-31/41 series) nozzle was unshrouded, which might eventually change as its development progresses.
