The new MK39 units, which offer a significant reduction in weight and size, has auto select features that will support the delivery of highest quality data to the ship.

"Northrop Grumman is pleased to have been awarded a contract by the New Zealand Ministry of Defence for this crucial upgrade."

The 118m-long Anzac-class frigates vessel have a displacement capacity of 3,600t and are capable of accommodating a crew of 163.

Powered by a combined diesel or gas turbine system, including a GE LM 2,500 gas turbine and two MTU 12V 1163 TB83 diesel engines, the vessels have a speed of 27k, with a maximum range of 11,000km.
