With modern U.S., Chinese and Turkish UCAVs already operationally deployed in a multitude of nations and conflicts worldwide, Russia has been notably lagging behind in the development and production of such drones. Favouring instead attack helicopters like the Ka-52 and Mi-28 to perform strike missions while loitering over the battlefield, they adhere to a doctrine that disregards the UCAV's carefully executed reconnaissance and strike operations for more aggressive search and assault missions. Each new conflict of the modern age seems to showcase the merit of the UCAV to greater detail however, and Russia has thus increasingly opted to invest in the concept as well.
