The Kamov design bureau developed a technology that allows fighter helicopters to accelerate to 600 kilometres (or 372 miles) per hour, which is faster than what a similar US helicopter can do, Chief Designer Sergei Mikheev said.

“I was able to find a solution, I patented it, for a fighter helicopter to fly at over 600 kilometres per hour”, Mikheev said at the MAKS-2019 air show, currently underway in Moscow region’s Zhukovsky.

Kamov is part of the Russian Helicopters company.

The MAKS-2019 International Aviation and Space Salon will run through 1 September. Rossiya Segodnya International Information Agency is an official media partner of the event.
