Most ship availabilities follow a milestone schedule. Depending upon the shift of the ship availability, there may be a bona fide need of the pre-ship availability work. This would depend upon the milestone schedule as well as the color of the funds utilized for the pre-ship availability work. For example, if the ship availability shifts 2-3 months, and the pre-ship availability work, according to the milestone schedule, is to be conducted in the present, there is a bona fide need for the pre-ship availability work. Obviously there would need to be funding (color of funding) that matches the bona fide need and the work effort. If the ship availability shifted to a later date (a few years), then the bona fide need could also shift a few years according to the ship availability a milestone schedule, and the corresponding funding would also need to be revised to the new fiscal year(s).
