Check out the HMS Illustrious!
She's an aircraft carrier - which is a ship that is built to be big enough for planes and helicopters to take off and land on it.
She's 210 metres long and weighs a jaw dropping 22,000 tonnes - that's the equivalent of 1,760 double decker buses.
During her 32 years in service, HMS Illustrious travelled an incredible distance and now it makes her final journey to Turkey to be recycled.
