Mikoyan MiG-31K fighter jets equipped with Kinzhal hypersonic missiles flew over Moscow's Red Square to commemorate the 73rd anniversary of the victory over Nazi Germany in World War IIAccording to a report by the Government Accountability Office (GAO),the United States lacks the necessary defense measures to defend against new highly complex hypersonic weapons from China and Russia.

The report states,"China and Russia are seeking hypersonic weapons because their speed, altitude, and maneuverability could potentially defeat most missile defense systems, and they could be used to enhance long-range conventional and nuclear strike capabilities." "There are no ready-made countermeasuresEarlier this year, the Russian military announced that it had successfully tested a nuclear capable hypersonic missile capable of infiltrating enemy defenses.

A video released by the Ministry of National Defense on Sunday showed a MiG-31 fighter jet launching a Kinzhar missile during a training flight.The department stated that the missile carrying a conventional warhead hit a training target at a shooting range in southern Russia.

Russian President Vladimir Putin stated that Kinzhar's flight speed is 10 times faster than the speed of sound, with a range of over 1250 miles, and can carry nuclear or conventional warheads. The military stated that it is capable of striking land targets and naval vessels.

When Russian President Vladimir Putin delivered his annual speech to the Russian Federal Parliament at the Manezh Central Exhibition Hall in Moscow, a video screen showed the Kinzhal missile systemThe Chinese military has been busy enhancing its hypersonic weapon capabilities.

In April of this year, the Pentagon announced an agreement with Lockheed Martin to develop a "hypersonic conventional strike weapon" for the US Air Force. The transaction value of hypersonic conventional strike weapons (HCSW) launched from the air is as high as 928 million US dollars.

Four months later, the US Air Force awarded Lockheed Martin a contract worth up to $480 million to design a second hypersonic prototype, the Air Launched Rapid Reaction Weapon (ARRW).The Air Force explained in a statement,"ARRW and HCSW are developing unique capabilities for combat personnel and each has different technological approaches." "ARRW's efforts are to 'drive possible art' by leveraging the technological foundation established by the Air Force/DARPA partnership. HCSW is using mature technology that has not yet been integrated into air launch systems

In response to GAO, the Department of Defense described the report as "an accurate but thought-provoking macro picture of how the United States responds to emerging threats in the world.

On Tuesday, Russian President Vladimir Putin cited the Kinzhal hypersonic missile and Avangard hypersonic glider launched from the air in a speech to senior Russian military officials, stating that they greatly enhance Russia's military capabilities.No one has hypersonic weapons yet, but we have them,"he said.

Kinzhal has been commissioned by the military, which puts them in service with a MiG-31 fighter squadron.Russian Defense Minister Shoigu stated on Tuesday that the missile carrying aircraft has conducted 89 patrol missions over the Caspian and Black Seas this year. Contrary to Putin's statement, US officials have stated that Russia has not yet deployed any hypersonic weapons that are still in the testing phase.
