Compared with traditional subsonic or supersonic weapons, hypersonic weapons have the advantages of fast strike speed, high flying height, and strong penetration ability. They can be used as a new type of conventional fast and precise strike weapons. The green laser pointer achieves sensitive targets outside the zone. Precise strike. As a strategic commanding height in the aerospace field in the future, hypersonic weapon technology has been widely recognized for its huge military value, and competition among major military powers in the field of hypersonic technology has become increasingly fierce.
Russia has listed the development and deployment of hypersonic weapons as one of its major priorities in the 2018-2025 national weapons and equipment plan. Among the six cutting-edge weapons and equipment displayed in the 2018 State of the Union address, there are two hypersonic weapons-a boost gliding hypersonic aircraft flying at speeds above Mach 20 and an air-launched hypersonic missile named “Dagger”. Russia has made real technological breakthroughs in developing new booster gliding hypersonic weapons, and has successfully tested them, saying that the weapon “like a meteorite” can fly in the atmosphere.
At present, Russia’s research on hypersonic boost gliding aircraft mainly includes Yu-71 and Yu-74. The hypersonic aircraft shown in this State of the Union report should be one of them. The Yu-71 has a flying speed of more than 11 thousand kilometers per hour. Its unique flight trajectory is different from ordinary warheads. After returning to the atmosphere, it can use its high lift-drag profile to perform hypersonic gliding at high altitude.
