RFA Lyme Bay is a Bay-class auxiliary landing ship dock (LSD(A)) of the British Royal Fleet Auxiliary (RFA). Ordered from Swan Hunter in 2000, the ship was launched in 2005. However, cost overruns and delays saw the shipbuilder removed from the project, and the incomplete ship was towed to Govan for finishing by BAE Systems Naval Ships. Lyme Bay entered service in late 2007; the last ship of the class to join the RFA.
