With the ongoing lack of will in congress to fund stepping up the Virginia class builds yea this is likely for the best. It's bad news though when even loosing one ship can put significant load on others to take up the slack. It's PP Planning and a dangerous plan. You have to have a causality cushion and today's numbers don't allow for such.
Both Houses of Congress and both parties are falling all over themselves to restore the second FY-14 boat in the shipbuilding plan. I don't know if there is a defense acquisition with more support.
