"UK forces participated in a joint operation with US forces against a Houthi military target in Yemen," the Ministry of Defence said in a statement, adding that the strike took place at night about 25 kilometres (15 miles) south of the capital Sanaa.
Britain has taken part in joint air strikes against Houthis led by the United States since early 2024.
Meanwhile, US forces have struck more than 1,000 targets in Yemen since Washington launched the latest round of its air campaign against the Houthi rebels in mid-March, the Pentagon said on Tuesday.
Since March 15, "USCENTCOM strikes have hit over 1,000 targets, killing Houthi fighters and leaders... and degrading their capabilities," Pentagon spokesman Sean Parnell said in a statement, referring to the military command responsible for the Middle East.
CENTCOM on Sunday had put the figure at more than 800 targets hit since mid-March, saying hundreds of Houthi fighters had been killed as a result.
Hours after that announcement, Houthi-controlled media said US strikes had hit a migrant detention center in the city of Saada, killing at least 68 people, while a United Nations spokesperson later said preliminary information indicated that those killed were migrants.
A US defense official said the military was looking into reports of civilian casualties resulting from its strikes in Yemen.
Attacks by the Houthis have prevented ships from passing through the Suez Canal -- a vital route that normally carries about 12 percent of the world's shipping traffic.
The group say they are targeting shipping in solidarity with Palestinians in Gaza, which has been devastated by Israel's military since October 2023.
