Any of you guys ever serve on DDG-14 the USS Buchanan? I used it as a cover shot for my latest book:
Sinkex 2000. They first hit it with a couple hellfires from helicopters. It just smiles and kept floating. Next 2 - 1000 lb laser guided bombs from an F-111 - still floating. Next, they hit it with a Mk 48 torpedo from a LA class nuclear attack sub - it malfunctioned. It took a seal team with a 1000 lbs of C4 to finally put it down the next day.
BTW, for you Navy guys, here's a great source of photos and history:
