Old video of Russian submarine test shared with false claim it shows Iran launching missiles

11 February 2026

What was claimed

A video shows Iran launching missiles from beneath the sea.

Our verdict

False. This video was posted by the Russian Ministry of Defense in 2018 and shows a Russian submarine testing intercontinental ballistic missiles.

A video of missiles being launched “from beneath the sea” has been widely shared on social media with claims it shows Iran’s “terrifying capabilities”.

But this video has nothing to do with Iran. It actually dates back to 2018 and shows a Russian submarine testing intercontinental ballistic missiles.

The clip alongside a misleading caption has been liked thousands of times online, but using reverse image search we traced it back to a video posted on YouTube by the Russian Ministry of Defense in May 2018.

The video is captioned “SSBN Yuriy Dolgorukiy successfully tests 4 Bulava missiles in salvo”. Local outlets reported at the time that the Russian Navy test-launched four intercontinental ballistic missiles from a nuclear-powered submarine in the White Sea.

In late January, Iran’s state media reported the country’s naval forces would carry out live-fire exercises in the Strait of Hormuz, a vital shipping lane between Iran, Oman and the UAE, on 1 and 2 February. But this reportedly did not take place.
