an Agile Tracker has been fitted. The main radar will be the Thales SMART-S Mk2 3D radar. Other sensors and upgrades include Link 16, laser warning, and IFF. The Lockheed Martin Combat Management System 330 is also installed on the RNZN frigates, as it increases the eyes on each screen, covering lesser sensors and crew. Operational history In 1999, Te Kaha pursued Patagonian Toothfish poachers in the Ross Dependency, participated in the INTERFET multinational deployment to East Timor, and operated as part of the Multinational Interception Force in the Persian Gulf. The New Zealand frigates served periods as guardships at the Solomon Islands capital of Honiara between 2000 and 2001. In 2002, Te Kaha returned to the Persian Gulf, this time as part of Operation Enduring Freedom, after a four-month flag-showing deployment in Asian waters. The frigate was replaced in the Gulf by Te Mana in early 2003. In March 2003, Anzac provided fire support for Royal Marines during the Battle of Al Faw during the 2003 Invasion of Iraq. A 2002 review of the RNZN's abilities found that the navy was not meeting its patrol capability requirements; one of the contributing factors was that the New Zealand Anzacs were both too few and overcapable for EEZ patrols, and deploying them in this manner prevented them from more effective use elsewhere. Remedying this was one of the aims of Project Protector, a multi-ship acquisition project which saw three new classes of ship enter RNZN service. From 2018, the Anzac-class frigates were undergoing their Midlife Capability Assurance Program (AMCAP) upgrade at the Australian Marine Complex, Henderson, Western Australia, a process scheduled to be completed by 2023. Arunta was the first ship to undergo the upgrade, followed by Anzac and Warramunga. Planned replacement The RAN plans to begin removing their Anzacs from service from 2024 onwards. To replace them, the Hunter class of new frigates will be built under the SEA 5000 acquisition project. The frigates are predicted to have a displacement of up to , and although they will be primarily oriented towards anti-submarine warfare, they are expected to be capable of also operating against air, sea-surface, and land targets. Originally eight vessels were planned, but by August 2015, the number of planned ships had increased to nine, with an estimated cost of $20 billion. Construction is predicted to commence in 2020. The Abbott Government promised that the two-decade construction project
