Interesting ensign to be flying at the time of her launch, when in theory she was still the property of the yard. I guess I have missed the point and RFA had a different approach to either the RN or the MN as to the time of taking over title of their ship..
What me? I know nothing! As far as I know RFAs are usually launched with RFA Ensigns. This appears to be a plain Blue Ensign but maybe the anchor is lost in the folds. Or perhaps they just didnt have one to hand.
She wore a Red for the sea trials.
