A Royal Navy destroyer is leaving Portsmouth today to help in the fight against Islamic State.
HMS Daring will head towards the Persian Gulf and will protect US aircraft carriers conducting bombing against targets in Iraq and Syria.
The £1bn destroyer, which has a crew of 190, will also patrol some of the world's busiest shipping lanes as part of her mission.
Similar Type 45 destroyers have faced engine problems in the same area, because they were not designed for temperatures in the region.
Commanding Officer, Philip Dennis, HMS Daring, talks about the mission.
