HMAS Arunta receives new mast

Royal Australian Navy Anzac-class frigate, HMAS Arunta, has received its new mast as part of its Mid Life Capability Assurance Program (AMCAP) being undertaken at BAE Systems Australia’s Henderson facility.

The new mast has been manufactured by BAE Systems as part of the Warship Asset Management Agreement between BAE Systems, SAAB Australia, Naval Ship Management and the Commonwealth of Australia.

The mast installation is one of the last major works on the ship ahead of its undocking before the end of 2018. The vessel will then undergo sea trials ahead of a planned return to service in 2019.

The new mast is taller and wider than the existing mast in order to accommodate the new CEA L-Band radar system, while retaining the existing anti-ship missile defence radar capability. The new L-Band radar capability will be integrated into the existing combat management systems of the ship by SAAB Australia.

Upon completion of the AMCAP, HMAS Arunta will have upgraded ventilation systems; new sewage systems; improvements to the control and monitoring system; engine modifications to improve power and efficiency; and a new communications suite.

The control and monitoring system of the ship has also received a technological enhancement, replacing existing analogue technology with digital. Integration of the communications system into the existing data communications systems has been closely managed during design by Leonardo.
