Russian naval forces launched long-range cruise missiles on Tuesday evening from the waters off Sevastopol, a port city in Russia-held Crimea, according to expert analysis of video verified by The Washington Post.

Russia said the 3M-14 Kalibr cruise missile attack destroyed a major Ukrainian arsenal.

A video filmed by a witness from the Sevastopol waterfront on Tuesday shows at least four projectiles being fired from the water. Geolocation of the video by The Post shows the missiles appear to be traveling northwest, away from the city. As the narrator recites the date and location, the camera pans to show his surroundings.

“We thought it was a plane flying,” the narrator says. “It’s normal that planes fly here. But shooting is something serious.”

Additional video filmed around the same time shows eight flares with long tails that appear to be airborne missiles flying over the Black Sea. Both videos were verified by The Post.

Footage shared by the Russian defense ministry on social media shows large fireballs emanating from a warship where the ministry said Russian forces had fired Kaliber cruise missiles toward military assets in Orzhev, a village outside of the city of Rivne. Rivne is located more than 200 miles west of Kyiv and would be within the range a 3M-14 Kalibr missile could travel if it was fired from Sevastopol.

The tightly cropped video first shows multiple large explosions in succession above a ship, while someone off camera counts, “First, second, third, fourth.” The video then cuts to a wider view of a sunset where the long tails of the eight missiles are visible. The Post was not able to verify the location of this launch.

“As a result of the strike, a large depot of weapons and military equipment of the Ukrainian troops, including those received from Western countries, was destroyed,” a statement on the ministry’s Telegram channel said.

U.S. officials said they could not confirm that the weapons had been used. Ukrainian authorities have not confirmed the deployment of the missiles or the destruction of an arsenal near Rivne.

The Post could not independently verify Russia’s claim that a weapons depot had been destroyed.

Ian Williams, deputy director of the missile defense project at the Center for Strategic and International Studies, said he was nearly positive the videos showed the launch of 3M-14 Kalibr cruise missiles.

“These are Russia’s long-range naval sea-based cruise missiles, similar to the U.S. Tomahawk,” he told The Post in an email. “They use satellite navigation along with some onboard inertial guidance.”

“This was almost certainly launched by the Russian Black Sea Fleet,” Mark Cancian, senior adviser for the international security program at CSIS, said in an email. Kalibr missiles are “at the high end of Russian capabilities,” he added. “Russia uses them to attack the highest priority targets. They seem to be doing more of that in western Ukraine. It may be part of an effort to attack strategic targets, that is, targets that matter in the long war.”

The 3M-14 or SS-N-30A cruise missile, commonly referred to as the Kalibr missile, can be fired from ships or submarines toward land targets. It can travel a maximum range of about 1,550 miles, according to the CSIS Missile Defense Project.

The missiles, designed to penetrate the air defenses of stationary ground targets, fly autonomously and largely horizontally at low altitude, along preprogrammed waypoints. Their route can be updated midcourse via satellite communication. Cruise missiles can be highly accurate compared to ballistic missiles.

The standard 3M14T land-attack missile reportedly contains a nearly 1,000-pound high explosive warhead. It is often used to attack storage facilities, command posts, seaports and airports.

Russia stuck barracks in the southern port city of Mykolaiv with a Kalibr missile earlier this month, the New York Times reported, killing at least eight Ukrainian soldiers who had been sleeping there. The region’s governor said at least 19 others were wounded.

A Pentagon official said at a background briefing Wednesday that the United States still assessed that Russia has “the vast majority” of its inventory of surface-to-air missiles and cruise missiles.

Russia first used the SS-N-30A Kalibr missile in Syria in October 2015, when it launched 26 missiles from Russian naval vessels in the Caspian Sea, at forces fighting the government of Syrian President Bashar al-Assad.

The latest: President Biden is headed for NATO’s eastern flank on Friday, when he will meet with his Polish counterpart — a visit that comes after the U.S. pledged to open its borders to 100,000 Ukrainian refugees.

The fight: Russia — which has launched more than 1,000 missiles so far — is increasingly relying on “dumb” bombs to wear cities and civilians down. Russia’s assault on Ukraine has been extensive with strikes and attacks across the entire country, and Russia has been accused of committing war crimes.

The weapons: Ukraine is making use weapons like Javelin antitank missiles and Switchblade “kamikaze” drones from the United States and other allies to combat the superior numbers and heavier weaponry of the Russian military.

Oil prices: Sanctions on Russia are helping gas prices hit new highs. Here’s why — and how long the surge could last.

In Russia: Putin has locked down the flow of information within Russia, where the war isn’t even being called a war. “Information warriors” from around the world are working to penetrate Putin’s propaganda wall.

How you can help: Here are ways those in the U.S. can help support the Ukrainian people as well as what people around the world have been donating.
