he main Russian hypersonic weapon are derived from space glider Yu-71 (Project 4202), which flew during tests at a speed of 6000-11200 km/h over a distance of 5,500 km at a cruising altitude below 80,000 m, receiving repeated pulses from a rocket engine to climb, execute maneuvers and cornering trajectory. It is estimated that the glider is armed with warheads that are spatially independent, with autonomous guidance systems similar to the air-ground missiles Kh-29 L/T and T Kh-25 (which provides a probable deviation of 2-6 m). Although it may take nuclear warheads, the space glider will be armed with conventional warheads and will be powered by a rocket launched normally from nuclear-powered Russian submarines.
The new Russian military doctrine states that an attack on the American invasion fleet is to be executed in three waves, three alignments, thus preventing American expeditionary naval groups from positioning themselves near the Russian coast of the Baltic Sea. The first wave of hypersonic weapons, consisting of space gliders arranged on Russian nuclear-powered submarines under immersion in the middle of the Atlantic, starts fighting US naval expeditionary groups as they start crossing the Atlantic to Europe. The American naval groups need 7-8 days to cross the Atlantic; the plane Il-76MD-90A has a maximum flight distance of 6300 km and can be powered in the air, reaching the middle of the Atlantic Ocean in a few hours.
