The Fleet Solid Support Ship Programme (FSSP) aims to deliver up to three fleet solid support ships to the British Royal Fleet Auxiliary. The ships will be used to provide underway replenishment of dry stores, such as ammunition, spare parts and supplies, to ships of the Royal Navy. They will regularly deploy with the UK Carrier Strike Group, providing crucial supplies to the Queen Elizabeth-class aircraft carriers and their escorts. All three ships had been scheduled to enter service between 2028 and 2032. However, subsequently the Ministry of Defence indicated that the first ship would in fact not be operational until 2031.
