HMS Belfast celebrates the 75th anniversary of its launch this weekend.
It was one of the largest and most powerful cruisers in the Royal Navy and saw more than 30 years of active service.
The vessel has been moored on the River Thames since 1971 and veterans and VIPs are returning this weekend to celebrate.
Robert Hall has been to meet some of those who served on the ship.
