I'm no kind of expert on this, but I didn't think yard capacity was the issue. I read a while ago the BIW president saying they could build two additional DDGs per FY with their current infrastructure. I imagine HII is similar. NNS could build a CVN in four years instead of 5+. I don't know about the Sub yards but Virginia-class production is mature and humming along. The production schedule is stretched out to spread costs over multiple budget years and make the arithmetic work, not because there aren't enough workers or big enough plant. How much would a SLEP cost, and could we get new construction of a 30-year-lifespan hull for the money instead?
It's as if when you make a number the goal, then everyone quickly becomes target-fixated on reaching that number, whether it makes sense or not. There are some pretty fundamental questions that are still unanswered before anyone can say whether a 5-10-year SLEP helps you or not.
- What's our national strategy? What do we need our Navy to do?
- How many and what kinds of ships do we need to accomplish that strategy?
- If we need to ramp up production, what do we do to sustain the industrial base once the 'surge' is done? And can we afford it anyway?
- If SLEP is the answer, what comes after the 5-10-years?
- If SLEP is the answer, does that mean we can meet our tasking with current designs? In which case, why not build more of the existing design, since it works well enough?
- If our existing ships aren't suitable, then why are we SLEPing them?
Overtasked in terms of the Fleet tasking requirement that is running the Fleet ragged, not yard capacity.
BIW/HII do not get involved (with very limited exceptions) with ship maintenance once the ship's leave the BIW/HII shipyard. I'm fairly certain the CVN side is similar but maybe not.
The mid-life overhauls/modernizations are done at a mix of Government and private shipyards, usually done near the major Fleet bases.
Generally there would be 2 sides of SLEP.
1 would be the HM&E stuff to keep the ship's plant running and in general keep shit from falling apart.
On the actual combat systems side, we are turning ship's commissioned in 1990 into state of the art warships more capable than those built 10 years ago. So you can definitely make them suitable to meet current/advanced threats.
The latter doesn't help if the former isn't a viable option. The point NAVSEA is making is that some of the older ships do have good life remaining in the hulls. So as an example, you could run the same modernization on some of the CGs sitting around in inactive status, and bring them up to the capability of the most advanced surface combatants we've got.
