Australia’s Navy relies on one frigate in particular
The Royal Australian Navy has a big job, even though it is a relatively small force. This force relies on one ship as its backbone, the Anzac-class frigate, and those frigates have been on the front lines for Australia and New Zealand.
According to the Sixteenth Edition of The Naval Institute Guide to Combat Fleets of the World, Australia has eight of these vessels in service, while New Zealand has two. These ships can be very powerful, and are based on the MEKO 200 design from Germany, a vessel that has also been sold to Turkey, Algeria, Greece, Portugal, and South Africa.
Australian Anzac-class frigates are heavily armed. They have an eight-cell Mk 41 vertical-launch system for the RIM-162 Evolved Sea Sparrow Missile, a five-inch gun, eight RGM-84 Harpoon anti-ship missiles, and the ability to operate a Sikorsky MH-60R Seahawk multi-mission helicopter. They also have Mk 32 launchers for 324mm torpedoes. These vessels have received upgrades for defending themselves against anti-ship missiles. These upgrades are centered around the CEAFAR and CEAMOUNT phased-array radars.
The New Zealand Anzacs didn't get the same upgrade, largely due to the collapse of the ANZUS mutual-defense treaty in the 1980s, spurred by New Zealand's anti-nuclear policy. As a result, the Te Kaha and Te Mana have a less-capable system. Their Mk 41 vertical launch system initially only fired RIM-7 Sea Sparrows, and they operate SH-2G Sea Sprites. An upgrade, though replaced the old Sea Sparrows with the Sea Ceptor system from the United Kingdom
These frigates will still be around for a while. Australia plans to replace them with one of three designs (the French-Italian FREMM, the British Type 26m, or a modified Spanish F100) starting in 2024. New Zealand's will remain in service until 2030.
