Based on a modified German MEKO 200 design, the ten Anzac ^[1] class frigates are the major surface units of the Royal Australian Navy ^[2] (RAN) and Royal New Zealand Navy (RNZN).

Built by Tenix Defence Systems using modular construction techniques, hull and superstrucuture modules were built in both New Zealand and Australia. Final fitout was in Williamstown, Australia. Eight ships serve in the RAN and are numbered FFH 150 - FFH 157. The two RNZN ships are F77 and F111.

[edit] Australian improvements

• CEA SSCWI fitted for control of the ESSM missile in upgraded RAN units.

• Upward creep in ship manning led the RAN to undertake a habitability upgrade study. Additionally, restructuring the Marine Engineering Department has resulted in a change in the rank / billet structure, creating a need to re-work some habitation areas. Habitability upgrades are intended to provide added flexibility for additional training bunks, force protection personnel, special operations personnel and mixed genders onboard the ships, by increasing the ships berthing by +11 from 174 to 185 berths. The additional +11 berths have a ranking mix of +2 Officers, +2 CPO's, +2 PO's & +5 JR's. Arunta has completed her upgrade and remaining units will follow.

• The Harpoon anti-ship missile is being fitted to Australian units. Work was complete on the first upgraded ship, HMAS Warramunga,in 2004. For a number of reasons related to operational considerations and the electronic environment, the Harpoon installation was relocated from its reserved space and weight position on 02 Deck to a position on 01 Deck forward of the bridge. Remaining units will be upgraded in due course.

The Australian Defence Department decided to upgrade their Anzacs even before all ships were completed, the upgraded configuration includes, RGM-84 Harpoon anti-ship missiles fitted in two Quad Launchers, Evolved Sea Sparrow Missiles Quad Packed in VLS enabling 32 missiles to be carried, 4 Nulka active missile decoys and the Petrel Mine and Obstacle Avoidance Sonar system. All upgrades and new builds are scheduled for completion by 2006.

Subsequent upgrades will focus on anti-ship missile defence, and are slated to include, an additional fire control channel, IRST (Infra-red search and track) system and two RIM-116 Rolling Airframe Missile close in weapons systems. In September 2005, the RAN selected the CEA Technologies CEA-FAR 3D E/F band, fixed active phased array radar for improved fire control against anti-ship missiles. The radar will enter service from 2009.

[edit] New Zealand improvements

• Phalanx CIWS fitted to RNZN units.
• ESSM to be fitted from 2008.

[edit] New Zealand frigate controversy

The purchase of the frigates was opposed in New Zealand by a coalition of those in the minority Green Party basically opposed to any defence spending.^{[citation needed]} It did not help that the purchase was supported by the New Zealand National Party and became a political issue. However the majority of New Zealanders objected to buying these particular frigates.^{[citation needed]} The reasons were complex, but included perceptions the ANZAC frigates offered poor capability for the cost, the frigates were a make work scheme for uncompetitive Australian dock yards and any purchase as surrender to Australian political pressure.^{[citation needed]}

The Australian government undoubtedly did place pressure on the New Zealand government to make the purchase, but their public reasons were that New Zealand firms would receive much of the work and that it was important to ensure compatibility between the ships of both nations.^{[citation needed]}

While the decision was still being made, the Australian manufacturer placed advertisements in New Zealand promising engineering work to Kiwi firms, and did eventually subcontract a significant amount of work to New Zealand.

Plans to buy an additional two frigates were eventually dropped, largely as a result of public and treasury pressure.^{[citation needed]}

This has left the New Zealand Navy with only two frigates, while some believe four vessels of similar capability could have been purchased for the original price.^{[citation needed]} New Zealand frigates HMNZS Te Kaha and Te Mana have not received the same standard of equipment as their Australian counterparts^{[citation needed]} (with the exception of their new build Kaman SH-2 Seasprite helicopters, which have in service not experienced the reliability problems of Australia's second-hand purchase).

Te Kaha and Te Mana have seen service in East Timor, the Persian Gulf and pursuing poachers around Antarctica.
