The Royal Australian Navy's Anzac class frigate HMAS Parramatta is preparing to undock in mid-April this year from a shipyard in Henderson, Western Australia, following a 12-month upgrade programme.
The ship is Australia's fifth Anzac class frigate, and the sixth to enter the Anti-Ship Missile Defence Upgrade programme.
Work under the project included replacement and upgrades to the combat system, as well as removal of the propulsion and electrical generation system.
BAE Systems, Saab Australia and Naval Ship Management delivered a range of engineering changes and maintenance tasks during the programme.
Prior to docking in late April last year, Parramatta underwent a comprehensive safety and preparation phase at Fleet Base West in February.
During this time, the vessel was completely emptied of all stores and supplies, de-fuelled, and cleaned in an extensive operation undertaken by the crew and contractors.
Removal of some major radar and other antennae, and upper deck fixtures also commenced, allowing more efficient use of time on the dock to achieve the major upgrade work.
Capability Acquisition and Sustainment Group, Anzac System Program Office was handed over material control of the vessel after it was docked.
HMAS Parramatta's crew moved to the sister ship HMAS Warramunga for return to navy service following completion of the upgrade.
The guided missile vertical launch system was also removed to allow access for engine removal, which then allows them to be overhauled offsite and replaced in the vessel prior to undocking.
By October last year, the entire outer hull was blasted back and coated in a red preservation undercoat.
The new masts, built on the base of the original masts with new upper structures, cables, services, and a new paint scheme, were lifted into place on in November.
More than 600,000h of individual labour services were provided for the upgrade of Parramatta.
