USS Zumwalt Rolls Out of Ultra Hall
March 2012 - 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.
