I believe it is meant to be this ship. I'm not sure whether we should put in the OTL part at the top and make this a sub-section but I do think renaming the article to "HMY Britannia" would be appropriate. ML4E (talk) 16:39, September 20, 2016 (UTC)
At a minimum, retitle. Not sure if we should dogmatically say it's the OTL ship, given that T2G runs counter to expectations about as often as it fulfills them. TR (talk) 16:58, September 20, 2016 (UTC)
