Which, to be fair to the Navy, is as much Congressional meddling and military procurement seeding--if you stop paying your contractors, they stop being military contractors and the knowledge you'd like walks out the door, which doesn't excuse the LCS program but does explain some of it--as anything else.
When we say that we're bad at procurement in the United States, there's a lot of targets for blame. (I think you're right that the Air Force tends to have the best project execution of the service branches though.)
