The frigate is undergoing its Anzac Midlife Capability Assurance Program (AMCAP).
The upgrade programme is being conducted at Henderson shipyard.
This programme will help Anzac frigates fill the requirement gaps, especially after the decommissioning of Australian vessels HMA Ships Success (II), Melbourne (III) and Newcastle.
Upgradation works on Anzac include the installation of a new phased array air search radar with an enhanced communications suite.
The upgrade will also provide an improved cooling system with other platform systems remediation (PSR).
PSR involves the upgrade of propulsion control, fridges, waste management, and water production systems.
The programme aims to make Anzac ready for combat and ‘fit to fight’. It also seeks to make sure the Anzac Class Frigates remains effective until the Hunter Class Frigates are introduced.
After the completion of the upgrade programme, the frigate will undergo sea trials and is expected to re-join service with the navy this year.
HMAS Arunta (II) was the first Fast Frigate Helicopter (FFH) to receive the upgrade.
It rejoined the fleet in June last year after completing a 20-month AMCAP upgrade.
AMCAP is a Warship Asset Management Agreement (WAMA) project. It is an alliance between the Commonwealth’s Capability Acquisition and Sustainment Group, Saab Australia, BAE Systems and Naval Ship Management Australia.
BAE Systems Australia is the prime contractor for the construction and development of the Anzac-class frigate.
In September last year, BAE Systems installed a new mast on HMAS Anzac.
