Enter the Beast...

To paraphrase Crocodile Dundee:

That's not a ship...


...that's a Ship.

Random fact derived from Wikipedia and a calculator - PS is heavier than 2 US Carrier Battle Groups (i.e  1 is a carrier plus 5 escort warships). Not that that scale is any easier to get your head around.

In the extras the bridge of the 'little' ship alongside PS is probably the height of a 4 storey building.
