Re: The operational status of NCC 1701-A...?
For me I always believed that it probably was a rush build from existing segments (abandoned new build because of Excelsior class) due to Scotty's line about the ship being put together by monkeys. I don't think that makes sense if it is a repair or refit on an existing ship.
It would if the refit was a rushed job and not all of the systems were fully tested (or even fully integrated) when she was commissioned.
