Amazing timelapse. Ultra 2200, the second of 4 Ultra units for the future USS Zumwalt,
rolls out of the Ultra Hall at Bath Iron Works and gains two smaller
units before being joined to Ultra 1400 (rolled out last fall). At 4500
tons, this is the largest ship module ever moved by BIW. Two thirds of
the hull are now on the ways, with another hull module and the composite
deckhouse still to come.
