CHARLOTTESVILLE, Va., Sept. 2 (UPI) -- Navigation suites on ANZAC-class frigates of the Royal New Zealand Navy are to be replaced with new units by Northrop Grumman.
The new inertial navigation suites -- fourth generation MK39s -- feature an embedded data distribution system. They are also lighter and smaller than the MK49 units they are replacing and have auto-select features that ensure highest quality data.
