A report by the UK's Royal United Services Institute assesses Russia's electronic warfare to be a critical tactic of Russia in the war that has caused staggering losses of Ukrainian drones. 

The report assesses daily losses to amount to a total of 300 drones every day, citing anonymous Ukrainian officers interviewed in April and May. 

James Patton Rogers a professor of war studies at the University of Southern Denmark describes the war in Ukraine as the world's first "drone vs. drone conflicts". 

Rogers notes that the losses in Ukrainian drones reflect the finesse of Russian electronic warfare. 

The report by the Royal United Services Institute said that along the roughly 750 miles of the conflict's front line, Russian electronic warfare systems were activated every 6 miles. 

The Shipovnik-Aero system is one of the Russian electronic warfare signals which distorts the navigation of Ukrainian drones by sending fake signals. 

Ukraine holds a variety of drones in its arsenal ranging from commercial-grade UAVs to the multimillion-dollar Bayraktar TB2.

He added that number of countries, including Poland, have begun training Ukrainian pilots in flying F-16 fighter jets.
