Background information on paying for our Navy. Bottom line: we can't get the numbers the Navy says it needs with the building plan the Navy wants.
If numbers matter, we can get them. It just depends on whether the Navy accepts less capable ships to reach that number.
The Navy needs to adapt to the budget realities. Saying that such a reality-based course will result in a Navy they don't want ignores that by ignoring reality the Navy won't be what they want it to be anyway--and it won't be better.
