Can a Galaxy class starship be built in less than 2 1/2 months?
An existing starship can be named in less than two and a half months. Example, the Enterprise A. While not actually mentioned on screen, many fans think that the Enterprise A was a existing ship that was renamed. Either a newly built ship that had it's name change, or a older connie that was rebuilt as the Enterprise was in TMP, then renamed.
