Also, the British have named a bunch of ships "Nimrod" in centuries past. I think the name has a bit of dignity because of that.

IIRC we Brits also have/had some sort of reconaissance aircraft by that name too.

Also, wasn't there a living-metal future-sentinel type thing in the X-Men stories that was called Nimrod and was pretty terrifying?
