Did the United Kingdom send warships to the Black Sea to attack Russian submarines during the 2022 Russia-Ukraine conflict as of July 25, 2022? No, that's not true: No credible reports suggest that the Royal Navy sent warships or attacked Russian submarines in the Black Sea. Also, the images in this video post are taken from an article that instead reports that the Royal Navy was surveilling Russian submarines in the North Sea.
The claim appeared in a Facebook post on July 24, 2022. The post features a video with a caption that reads:

A Google search using keywords "British Royal Navy Warships Attacked Russian Submarines in The Black Sea" produced no results that substantiate this claim.
Searching for "Russia submarine" on the Royal Navy website revealed an article about a Royal Navy warship tracking the movement of Russian submarines in the North Sea. The images at 0:30 in the video are the same as those in this July 23, 2022, BBC News article titled, "Royal Navy tracks two Russian submarines in the North Sea." The article verifies the Royal Navy's HMS Portland tracking "cruise missile submarine Severodvinsk after it surfaced" -- not attacking it.
