Although the conflict between Russia and Ukraine took the form of "behind the times" war that was unexpected to the outside world, the Pentagon is still anxious about the slow progress in hypersonic weapons. Bloomberg said on the 7th that due to the failure of three consecutive tests of the air force's agm-183a air launched hypersonic missile, the tense schedule of the U.S. military to catch up with China and Russia in this field is bound to be delayed. Agm-183a air launched hypersonic missile It is reported that Lockheed Martin's agm-183a air launched hypersonic missile failed three consecutive tests, which may frustrate the efforts of the United States to catch up with China and Russia with hypersonic weapons. "According to the Pentagon's plan, the missile will become the first hypersonic weapon available for combat in the United States, and initial production will begin before September 30. Now this compact timetable has been widely questioned.". "China and Russia have tested and deployed their respective hypersonic weapons. They can fly and maneuver at five times the speed of sound, making them more difficult to find and shoot down." According to the report, the United States faces many obstacles in the development stage of hypersonic weapons. In order to catch up with the time, the Pentagon has reduced the development time originally required for several years to a few months. Agm-183a missile is planned to be launched by b-52h strategic bomber and start the booster engine. After reaching a certain speed, the glider warhead will separate from it and fly to the target at hypersonic speed. However, due to the failure of the first three tests, Lockheed Martin must carry out the fourth and fifth tests on its engine before June 30 this year, so as to carry out the most critical flight tests from July to September in accordance with the Pentagon's "radical schedule" and complete the preliminary preparation for mass production. At present, it is estimated that it will cost at least $1.4 billion to ensure its "early combat capability". Even so, the U.S. Air Force has not yet released an estimate of the total procurement cost or how many such missiles it wants. According to the report, the production of the first batch of 12 missiles originally scheduled to start in January has been temporarily put on hold, waiting for the early failure review results. The project office said, "if there is no production preparation review and successful all-round flight test, the production contract will not be awarded." According to the report, compared with the slow progress of the United States, China and Russia take the lead. As an ally of NATO, it also sent a "warning signal to Russia before the Hypersonic Missile Invasion". At present, Russia has deployed "dagger" hypersonic glider and "zircon" hypersonic cruise missile. Russian Defense Minister Shoigu said that hypersonic weapons will become the core of Russia's future non nuclear deterrence capability. The report also mentioned that according to the US strategic command, China is also investing heavily in hypersonic weapons. Faced with the development of hypersonic weapons between China and Russia, the Pentagon is anxious. Xu Ruobing, Chinese American Deputy Defense Secretary in charge of research and engineering, said she "supports the efforts of the air force to actively accelerate development", but "the formation of initial combat capability on September 30 is a very radical timetable." The US Air Force said that so far all tests have failed, but "if the future flight test ends according to the current plan", "it is still possible to provide this capability as planned". Kelly seller, an advanced technology analyst at hypersonic and other technologies, admitted that the US air force wants to obtain the first hypersonic weapon as planned on September 30, "leaving little room for test delays or additional flight failures", so it will be extremely challenging to complete the project on schedule.
