Actually, two a month is a pretty good rate of production. They’re not chevy novas.

I do know the unit cost of both the A10 and the F15 (as examples I was familiar with back in the Stone Age) would have been significantly lower had they been produced at a more rapid pace. The same was true of the initial F18s the Navy purchased, or so I'm told by a retired friend who was at the time involved in aircraft procurement.
This particular variant is specialized so it's something of an exception. I still don't see how the slower pace of production is anything other than Congress looking at people in their district being employed rather than the real cost to taxpayers.
