Northrop Grumman Corporation has received orders to supply integrated bridge systems for five new roll-on/roll-off (ro-ro) vehicle carriers being built for Grimaldi Group Naples by Croatian Shipbuilding Corporation at its Uljanik shipyard in Pula, Croatia. The ships will be fitted with a complete suite of navigation and communication systems to be supplied by Northrop Grumman’s Sperry Marine business unit in conjunction with Compania Generale Telemar. The navigation systems to be installed on the five new ro-ro ships will be based on Sperry Marine’s new-generation VisionMaster FT technology, which was unveiled at the 2006 SMM Exhibition in Hamburg.
