Which is the world's oldest naval ship still in commission?

I have visited this ship in Portsmouth but I don't consider it still in commission when it's not sailing anymore its a museum.

luckycatfay, acting as a museum is in commission

That's what I called Victory 😂😂😂

ImmovableSalesman4, my majority opinion, has not worked, for me, in a couple of months now!!

ImmovableSalesman4, I usually go with second most popular if it's close. also depends on what level you are playing. which isn't easy. my levels are jumbled. Y.N.W.A.    JFT96

majority vote seems to be wrong more times than right!!!
