The Bay class was designed as a replacement for the Round Table class logistics ships operated by the RFA. The new design was based on the Royal Schelde Enforcer design; a joint project between the Dutch and Spanish resulting in the Rotterdam class and Galicia class amphibious warfare ships. The main difference with the British ships is the lack of a helicopter hangar.

The ships were originally designated "Auxiliary Landing Ship Logistics" or ALSL, but this was changed in 2002 to "Landing Ship Dock (Auxiliary)" or LSD(A), better reflecting their operational role. Four ships were ordered; two from Swan Hunter, and two from BAE Systems Naval Ships.[1]

At the end of 2010, RFA Largs Bay was marked as one of the vessels to be removed from service under the UK Strategic Defence and Security Review. On 17 March 2011, the Department of Defence announced that the Royal Australian Navy would be bidding for Largs Bay. This was followed on 6 April by news that a A$100 million (£65 million) bid had been successful.

ADF Ship Choules was formally handed to the Australian Defence Force in October 2011 following extensive sea trials to confirm the condition of the vessel. The ship also underwent a major refit to make her suitable for RAN service as was commissioned as HMAS Choules on 13 December 2011.

The Bay Class has a large flight deck aft which can accommodate two large helicopters and a docking well in the stern capable of operating a LCM-8 or two LCVP landing craft.

The military lift includes the capacity to load and transport up to 32 Abrams tanks, or 150 light trucks. They can carry a normal load of 356 troops, or overloaded with 500. They are designed to operate over the horizon using helicopters and landing craft, to get men and equipment ashore.
