The US and UK have deployed warships to repel the Houthis who have been attacking commercial ships in the Red Sea.
The Iran-backed group have been targeting ships they claim are links to Israel and the West in protest against the war in Gaza.
The ships are a huge show of force by the US and its allies. They are meant to be acting as a deterrent and a show of support for Israel after the 7 October Hamas attacks.
BBC News has been given special access to US Navy warships that have been deployed to the region.
