A Royal Navy vessel with strong links to County Durham is set to become the region's flagship.
HMS Bulwark is one of the Royal Navy's biggest ships
HMS Bulwark, a 20,000 tonne amphibious assault ship, is affiliated with a number of organisations in Durham.
On Tuesday the commanding officer will be presented with a county flag to fly during the vessel's first major deployment since being commissioned.
Royal Navy ships are allowed to fly an "unofficial" flag when refuelling and replenishing alongside a support ship.
Captain Clive Johnstone studied anthropology at Durham University, and spent two years serving on board Durham City's former adopted ship, the aircraft carrier HMS Invincible.
He said: "I'm delighted at the prospect of renewing my acquaintance with County Durham, and am very much looking forward to building upon the friendships and affiliations which already exist between ship and shore."
