RMS CELESTIA

The RMS (Royal Merchant Steamer) CELESTIA along with her sister ship the RMS LUNA were Equestria's largest iron made oceanliners during the Great War and were to have the luxuries that would rival Canterlot Castle. The ships were to symbolise the advancement in technology during the war and to show the ponies of Equestria that if they could build such large ships then they could do the same for the war effort. The reason for these giant ships however was really to ferry ponies in the thousands away from Equestria to a safe land, though it was never revealed to the general public. 

The RMS CELESTIA was the second to be built with the LUNA being built a year before. She was scheduled for her maiden voyage during the later stages of the war but before she could embark the bombs fell so the ship never had her maiden voyage and remained in her dock. She sat there for two hundred years before she was discovered by Appletart and her friends.

Edit: Added the two tall vents and full cover railing on the bow from Raise the Titanic. This was something I intended to do last night before i uploaded her but forgot as i was in a rush to get her uploaded before i went to bed.
