Yeah I know.. but it still isn't odd, when you realise WHY the number is 433...
It's pretty straight foreward.. they could not start on her unless one of the other two was finished at least.
And in the meanwhile, they kept on building other ships.. it's not like they only had those two projects going.. Sop when it was her turn, they were further along the line..
So it's not odd or funny, or weird or strange at all. I guess they could have "reserved" the number for her. But the number is of no significance anyway. Not for anything other then their own bookkeeping reasons.
No ship is referred to by it's yard number.. they have names for a reason. No one really cared what it would be, I bet.
