Wednesday, the Pentagon claimed that Russia notified the US before conducting an intercontinental ballistic missile test.
The Pentagon said Russia's first test launch of its Sarmat intercontinental ballistic missile, a new addition to its nuclear arsenal, did not constitute a "threat" to the US and its allies.
On state television, Russian President Vladimir Putin praised the missile as a "truly unique weapon."
The weapon would "strengthen our armed forces' combat capability, ensure Russia's security against external threats in a reliable manner, and provide food for thought for those who, in the heat of frenzied aggressive rhetoric, attempt to threaten our country," Putin said.
"The new complex possesses the most advanced tactical and technical capabilities and is capable of defeating any modern anti-missile defense systems. It has no counterparts in the globe and will not for an extended period of time," Putin stated.
NATO has called the RS-28 Sarmat "Satan 2." It is Russia's most powerful intercontinental ballistic missile.
The Pentagon responded that the test was regular.
"Testing is routine, and this was not unexpected," Pentagon spokesman John Kirby said during a briefing to reporters.
Kirby stated that the department "has determined that the test poses no threat to the United States of America or its allies."
The United States According to the Congressional Research Service, Russia is planning to deploy the Sarmat later this year, with each missile carrying ten or more warheads.
According to Russia's Defense Ministry, the missile was launched that afternoon from the Plesetsk cosmodrome, located about 800 kilometers north of Moscow in the northern Arkhangelsk area. It targeted targets in Russia's far east, on the Kamchatka peninsula, approximately 6,000 kilometers away.
"This is the inaugural launch of the government's test program. After the test program is completed, the tested Sarmat missile system will be integrated into Russia's strategic missile capabilities," the Russian military stated following the missile test.
Russia's Defense Ministry, echoing Putin's words, added that the Sarmat would boost the power of Moscow's nuclear arsenal.
"The Sarmat missile possesses unique characteristics that enable it to defeat any existing or future missile defense systems with confidence," the ministry stated.
The test launch occurred at a time of high geopolitical tensions due to Russia's invasion of neighboring Ukraine on Feb. 24.
Kirby told reporters that the Pentagon "remains focused on Russia's unlawful and unprovoked aggression against Ukraine."
