, although the modular design of the frigates allowed construction to occur at sites across Australia and New Zealand. The RAN ordered eight ships, while the RNZN ordered two, with the option to add two more later. The frigate acquisition was controversial and widely opposed in New Zealand, and as a result, the additional ships were not ordered.

In 1992, work started on the frigates; 3600 tonnes (3,543.1 LT) ships capable of a 27 knots (14.7 m/s) top speed, and a range of 6000 nautical miles (11,112 km) at 18 knots (9.8 m/s). The armament initially consisted of a single 5-inch gun and a point-defence missile system, supported by a missile-armed helicopter. In addition, the ships were fitted for but not with a torpedo system, anti-ship missiles, and a close-in weapons system. The last ship of the class entered service in 2006; by this point, the RAN and RNZN had embarked on separate projects to improve the frigates' capabilities by fitting the additional weapons, along with updates to other systems and equipment.

. Eventually, the project settled on a ship of approximately 3600 tonnes (3,543.1 LT) displacement. At this time, it was also believed that Australia did not have the capability to design a major warship from scratch, so the decision was made to select a proven foreign design and fit it with an Australian-developed combat system. In early 1986, a review of policy regarding surface combatants saw the NSC classified into the middle of three tiers: a patrol frigate designed to operate on low- to mid-intensity operations in Australia's Economic Exclusion Zone.

; one such avenue was to promote military interoperability between the countries by standardising equipment and procedures where possible. The Australian NSC project was seen to have "virtually identical" requirements to the RNZN's proposed Replacement Combat Ship concept, and the need to replace the warships dovetailed with the need to improve relations with Australia.

On 6 March 1987, a Memorandum of Understanding was signed by the two nations and RNZN representatives were invited to collaborate on the project. To recognise their involvement, the project was renamed the Anzac Ship Project, taking the name from the Australian and New Zealand Army Corps

The New Zealanders' involvement was structured to allow their involvement in the selection of the design and shipyard and explore options for New Zealand industry involvement: when the time came to commit, they could either continue cooperating into the construction stage of the project, independently order the ships from the designer, or abandon the project entirely.

, and Royal Schelde with Australian Warship Systems.
On 14 August 1989, the Australian government announced that AMECON had been awarded the tender for construction of the Anzac class based on Blohm + Voss' modified MEKO 200 design. Although both the MEKO 200 and M class designs met the design requirements, the MEKO design was selected as more ships could be purchased for the budget cost. The A$5 billion contract was, at the time, the largest defence contract awarded in Australia. The decision was made despite ongoing debate in New Zealand over the project. New Zealand committed in principle to the purchase of two frigates plus the option for two more on 7 September, and the contract for the first two ships was signed on 10 November.

New Zealand controversy

From the mid-1980s onwards, the New Zealand government's planned acquisition of the Anzac class frigates was a major point of debate and contention: researcher Peter Greener claims that it "was possibly the most strongly debated defence purchase of the century". In New Zealand at the time, "frigate" was a dirty word, and attempts to make the replacement of the old navy ships more palatable to the public included using euphemisms like "ocean combat ship" and "ocean surveillance vessel". The government's official stance was dedication to maintaining a blue-water navy

), and military personnel. Most of the concern revolved around the cost of purchasing frigate-type ships, along with the idea that four high-capability warships would be too few and too overspecialised to operate in the roles envisioned for the RNZN.

The primary role foreseen for the RNZN was fisheries protection, particularly following the introduction of a 200 nautical miles (370.4 km) Exclusive Economic Zone

; this was thought to require a minimum of six vessels to effectively police. Peace campaigners claimed that the purchase of the Anzacs was a politically motivated decision made under pressure from Australia, which was trying to support its shipbuilding industry, and stated that the Fourth Labour Government was undermining its commitment to reduce the nation's deficit by spending so much on high-tech warships (although figures of $NZ20 billion for purchase and 20 years of operation was misquoted as an upfront lump sum). There were also concerns that by possessing modern warships, New Zealand would be "dragged" back into ANZUS. One proposal suggested to avoid this was that the New Zealand Anzacs be fitted with inferior engines that would reduce the vessels' top speed and make it impossible to operate with United States Navy

, the National Party retained power, but only in coalition with the New Zealand First party, which opposed the purchase of additional frigates. Other options for replacing the two remaining Leanders were explored, but these were generally more expensive than purchasing the Anzacs. Internal political opposition, particularly from New Zealand First, prevented the exercising of the contract option for two more ships before it lapsed on 10 November 1997, at which point the government was considering the purchase of a single frigate, outside the terms of the original contract. A year later, the idea was still being debated internally, although the proposal had been downgraded to buying one of the active Australian Anzacs second-hand, which the RAN could then replace by building an additional ship. At this point, the National-New Zealand First coalition had collapsed, and the National Party was only holding on to power by the support of minority parties and independents; support that was likely to be withdrawn if a third frigate was approved. Cabinet rejected the plan, and the issue of replacing the Leander class frigate was deferred.

Maximum speed is 27 knots (14.7 m/s), and maximum range is over 6000 nautical miles (11,112 km) at 18 knots (9.8 m/s). The frigates' range is about 50% greater than other MEKO-type frigates, due to an enhanced fuel supply. Originally, two gas turbines were to be fitted; this layout would have provided a top speed of 31.75 knots (17.3 m/s). The starboard turbine was cancelled to save costs.

The standard ship's company of an Anzac consists of 22 officers and 141 sailors. Onboard electricity requirements are met by four MTU diesel generators. Each ship can carry up to 29 cubic metres (1,024.1 cu ft) of dry provisions, 29 cubic metres (1,024.1 cu ft) of refrigerated provisions, and 54 tonnes (53.1 LT) of fresh water.

Armament

At the time of construction, the main weapon for the Anzacs was a United Defense 5-inch 54 calibre Mark 45 Mod 2 dual purpose gun. The forward-mounted gun is capable of firing 32 kilograms (70.5 lb) shells at a rate of 20 rounds per minute, to a distance of 23 kilometres (14.3 mi). The barrel can elevate to 65 degrees.

All ships were initially fitted with a ThomsonSintra Spherion B hull-mounted bow sonar, for active search and attack operations. From Warramunga onwards, ships were launched with a Petrel Mine and Obstacle Avoidance Sonar system. this was later retrofitted to Anzac. All ships were fitted for but not with a towed-array sonar, with the RAN and RNZN following separate acquisition programs for these. The frigates were also fitted for but not with SATCOM and a Helo datalink.

Construction

On 14 August 1989, AMECON was awarded the tender to build the Blohm + Voss designed frigate. The frigates were to be constructed at the AMECON shipyard in Williamstown, Victoria

 (formerly Williamstown Naval Dockyard), but the modular design of the frigate allowed sections of the ships to be constructed throughout Australia and New Zealand, with final assembly in Williamstown. Each vessel was made up of six hull modules and six superstructure modules. All of lead ship Anzacs modules were assembled at Williamstown, but for later ships, the superstructure modules were fabricated in Whangarei, New Zealand, and hull modules were built at both Williamstown and Newcastle, New South Wales

. Unlike previous shipbuilding contracts, AMECON was only contractually obliged to meet the navy's set commissioning dates for the ships; all other construction deadlines were to be determined at the shipbuilder's discretion.

The second and fourth ships to be built were allocated to the New Zealanders. The third and fifth ships to be produced were earmarked for the RNZN in the event that approval to order two more frigates was given, with two more ships for the RAN to be added at the end of the production run. Project offsets meant that construction costs for the New Zealand ships were about 20% less than the Australian vessels.

Steel cutting for the first ship, , commenced on 27 March 1992. Work on the first New Zealand ship, , began in February 1993. Anzac commissioned into the RAN in May 1996, and Te Kaha into the RNZN in July 1997. In early 2002, the first four ships found to have microscopic cracks in the bilge keel and hull plating. The ships' hulls were repaired and reinforced. Construction of the final vessel, , began in July 2003, with the vessel commissioning into the RAN in August 2006.

". The RAN and RNZN began to plan for upgrades to their frigates before all of the ships entered service: these upgrades were planned and executed on a national basis.

Australian modifications

The RAN commenced plans to improve their frigates' combat capability in 1996, with the Warfighting Improvement Program (WIP). Upgrades proposed under the WIP included installation of a phased-array radar, a second Mark 41 vertical launch system. The WIP was scrapped near the end of 1999, and plans for a less ambitious anti-ship missile defence (ASMD) upgrade were made. In 2004, Tenix, Saab, and the Department of Defence formed a Private Public Partnership to upgrade the anti-ship missile defence (ASMD) capability of the Anzac class, through the installation of CEA Technologies

 to for the ASMD upgrade. Both of the frigate's masts were replaced, and the operations room layout was improved. After completion in October 2010, Perth was used to test the modifications, with trials completed in July 2011. Approval to upgrade the other seven RAN Anzacs was granted in November 2011, with work on the the A$650 million refits to begin in 2012 and be completed by 2017.

From Warramunga onwards, the frigates were launched with the ability to carry and fire the RIM-162 Evolved Sea Sparrow Missile (ESSM) as a replacement for the Sea Sparrow missile; these were quad-packed into the Mark 41 launcher for a payload of 32 missiles. ESSM test firing occurred aboard Warramunga in January 2003. The modifications entered operational service aboard three ships in June 2004. A CEA Technologies solid-state continuous wave illuminator was also fitted as part of the ESSM system.

From 2005 onwards, the RAN began fitting the Anzacs and the Adelaides with Harpoon Block II missiles in two quad-tube canister launchers. The Australian Anzacs were fitted for but not with the launchers, but the original planned location on 02 deck was found to be unsuitable, and the launchers were relocated to 01 deck, in front of the bridge. Around the same time, the RAN began to fit all frigates deploying to the Persian Gulf

 torpedo prior to 2008. Toowoomba was the first Australian ship to fire an MU90 torpedo, during a test firing in June 2008.

The RAN commenced tendering for a helicopter design to replace the Seahawks aboard the Australian Anzacs in 2006, with a contract for 11 Kaman SH-2G Super Seasprite helicopters signed in 1997. In addition to the Anzacs, the acquired helicopter also had to be operatable from the class of offshore patrol vessels the RAN was planning to build with the Royal Malaysian Navy (Malaysia later withdrew from the plan, and the RAN acquired the smaller Armidale class patrol boats

, which were not helicopter-equipped), with a second contract to be signed for these at a later date. In order to get the best capability for the cheapest price, the Australian Department of Defence opted to have Kaman acquire 40-year-old SH-2F Seasprite airframes decommissioned by the United States Navy, and fit modern flight systems to the reconditioned airframes. This approach led to major delays, and the helicopters were found to be inoperable in low-visibility conditions. By 2006, ten of the helicopters had been delivered, but none were permitted to fly. The Super Seasprite acquisition was cancelled outright in March 2008.

New Zealand modifications

 weapons system, recycled from decommissioning Leanders, was fitted to each frigate in addition to the Mark 32 torpedo tube sets.

In 1997, the RNZN began steps to acquire five Kaman SH-2G Super Seasprite helicopters for the two frigates. Unlike the Australians, the New Zealand contract specified new-build helicopters. Kaman Aerospace loaned four SH-2F Seasprites to the RNZN while the new helicopters were constructed: the SH-2Fs operated from February 1998 to August 2001, when the first two SH-2Gs were accepted into service.

At the end of 2006, the RNZN placed an order for two Mini Typhoons for each of its Anzac class frigates. Unlike the Australian configuration, the New Zealand ships are only fitted with a single TopLite director.

In 2007, Te Kaha began undergoing a series of major upgrades as part of the four-stage Platform Systems Upgrade (PSU), planning for which started in 2004. The four areas of modification under the PSU were improved stability and compartment configuration changes, overhaul of the propulsion system, installation of a new integrated platform management system

. The stability upgrades were to accommodate predicted increases in displacement as updated equipment was installed on the ships. As part of the modification, the ships' quarterdecks were enclosed, creating space for a gymnasium and improved laundry facilities. Propulsion changes are primarily focused around replacing the TB83 diesel engines with the TB93, providing an additional 1.4 MW and higher speeds during diesel-only sailing. The IPMS replacement is prompted by the perceived obsolescence of the current system by 2013; as of 2009, tendering for the new system was underway. The environmental control upgrade is intended to improve personnel comfort during deployments to South East Asia, the Middle East, or similar climates, and will use more environmentally friendly products. Each stage of the upgrade is organised to occur simultaneously with ship maintenance dockings, with the first two upgrades being installed during each ship's major maintenance docking in 2009 and 2010 respectively, then the other two upgrades during the next docking in the 2011–2012 period.

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.

, a multi-ship acquisition project which saw three new classes of ship enter RNZN service.

Planned replacement

The RAN plans to begin removing their Anzacs from service from 2024 onwards. To replace them, a class of eight new frigates will be built under the SEA 5000 acquisition project. The frigates are predicted to have a displacement of up to 7000 tonnes (6,889.4 LT), and although they will be oriented towards anti-submarine warfare, they are expected to be all-rounders, with the ability to also operate against air, sea-surface, and land targets.

The New Zealand 2010 Defence White Paper indicated that the RNZN's Anzacs will be replaced around 2030.
