What does this mean?

Well, we're talking about it over at USNIBlog.

Also this AM, Lee sent something that fits the subject .... and shows more and more people are starting to see the "Terrible 20s."

O’Rourke crunches the numbers and finds that over the lifespan of the Navy’s 30-year shipbuilding plan, even if its shipbuilding requests are met, the Navy is currently projecting that it will face “significant shortfalls” in the numbers of attack submarines and cruisers/destroyers--even as the sustainment costs rise significantly. What’s more, after FY15 when the Navy builds less LCS and JHSV’s, it will start building a planned twelve replacement ballistic-missile submarines, which at $6-7 billion a pop, is equivalent to almost half of the service’s annual budget for new ship construction. In other words, something is going to have to give.
