Russia: On Tuesday, Russian President Vladimir Putin showed off the latest and most sophisticated weapons and called on other countries to try to follow them. "No country has weapons faster than sound, only we can do it first," Putin told a meeting of the Russian Defense Ministry. Like Russia, the United States and China are working on the project. Earlier this year, China said it was testing supersonic aircraft and the US Air Force had contracted Lockheed. Martin to develop missiles.


Last year, Putin similarly said that the supersonic missile system would be launched in 2019, but so far nothing has happened. Recently, the Russian leader showed the public the latest weapons, which he said could defeat the United States and NATO. But in the past, analysts have warned that no one supports Russia's show of military power. Russia also on Tuesday tested a Su-57 fighter jet in the Khabarovsk region, according to Russia's local news agency.
