Well, that certainly gives one quite some respect for how some seagoing warships have lasted all these years and why they eventually have to be taken out of service.
The battleship, USS Missouri, is still around after 66 years, although I'm sure the "moth ball" process, the refurbishments she went through, and the preservation and upkeep now she's moored at Pearl harbor helped a lot. In fact, I do believe she could still be called back into service if needed.
The nuclear aircraft carrier, USS Enterprise, will be in service for 52 years before they finally decommission her, projected for 2013.
And, Nimitz class nuclear aircraft carriers have an expected 50-year lifespan.
Pretty impressive.
