It's not often sailors get permission to take a baseball bat to a multimillion-dollar aircraft carrier. But when the Navy's aircraft carrier Harry S.

"[It said] 'Hey, when you get out to do this, when you head on out, don't forget to bring a bunch of baseball bats,'" said Chief of Naval Operations Adm. John Richardson.
