A promising US helicopter, presented by Lockheed Martin, was able to reach a speed of almost 460 kilometers per hour. In the video that the company published on its website, you can watch this.
We tested the Defiant helicopter. It is being developed for the US Department of Defense. In flight, the car managed to reach a speed of 247 knots - about 457 kilometers per hour.
Lockheed Martin reports that the Defiant will be equipped with a modern control system that will provide more reliable and safe flights at low altitude, with a large number of obstacles and in difficult natural conditions.
