This was the original Dreadnought - wasn't even a military vessel, it was a clipper ship and the fastest ship in the world at the time. Sandy Hook to Liverpool in 10 days. Unbelievable.
It's also the name of a Vancouver folk-punk band that also does Celtic, polkas and sea shanties...here's one of the latter about the clipper ship by that name...
The Dreadnought.
