HMS Belfast is the museum ship on the Thames, while HMS Caroline is a World War One light cruiser that is still in commission as a training ship for the Royal Naval Reserve in Belfast, Northern Ireland and is expected to be preserved and restored to her wartime appearance after she is finally decommissioned next year. At present, she is the second oldest warship afloat.

[PAR35]

At present, she is the second oldest warship afloat.

Not quite correct. Second oldest British warship in commission. .

HMS Victory is older, but in dry dock.

As for afloat, the USS Constitution (in commission and afloat), USS Constellation (afloat, not in commission)USS Texas (afloat, not in commission, plans are to take her out of the water, but that hasn't been done yet).

Off the top of my head. May be other older ships out there as well. But at best, number 4 on the list of oldest warships afloat.
