Design and Construction
The Anzac class originated from RAN plans to replace the six River class destroyer escorts with a mid-capability patrol frigate. Australian shipbuilding was thought to be incapable of warship design, so the RAN decided to take a proven foreign design and modify it. Around the same time, the Royal New Zealand Navy (RNZN) was looking to replace four Leander class frigates; a deterioration in New Zealand-United States relations, the need to improve alliances with nearby nations, and the commonalities between the RAN and RNZN ships' requirements led the two nations to begin collaborating on the acquisition in 1987. Tenders were requested by the Anzac Ship Project at the end of 1986, with 12 ship designs (including an airship) submitted. By August 1987, the tenders were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later Karel Doorman class) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defence) would build the modified MEKO 200 design. The Australians ordered eight ships, while New Zealand ordered two, with an unexercised option for two more.
The Anzacs are based on Blohm + Voss' MEKO 200 PN (or Vasco da Gama class) frigates, modified to meet Australian and New Zealand specifications and maximise the use of locally built equipment. Each frigate has a 3,600-tonne (3,500-long-ton; 4,000-short-ton) full load displacement. The ships are 109 metres (358 ft) long at the waterline, and 118 metres (387 ft) long overall, with a beam of 14.8 metres (49 ft), and a full load draught of 4.35 metres (14.3 ft). A Combined Diesel or Gas (CODOG) propulsion machinery layout is used, with a single, 30,172-horsepower (22,499 kW) General Electric LM2500-30 gas turbine and two 8,840-horsepower (6,590 kW) MTU 12V1163 TB83 diesel engines driving the ship's two controllable-pitch propellers. Maximum speed is 27 knots (50 km/h; 31 mph), and maximum range is over 6,000 nautical miles (11,000 km; 6,900 mi) at 18 knots (33 km/h; 21 mph); about 50% greater than other MEKO 200 designs.
As designed, the main armament for the frigate is a 5-inch 54 calibre Mark 45 gun, supplemented by an eight-cell Mark 41 vertical launch system (for RIM-7 Sea Sparrow or RIM-162 Evolved Sea Sparrow missiles), two 12.7-millimetre (0.50 in) machine guns, and two Mark 32 triple torpedo tube sets (initially firing Mark 46 torpedoes, but later upgraded to use the MU90 Impact torpedo). They were also designed for but not with a close-in weapons system (two Mini Typhoons fitted when required from 2005 onwards), two quad-canister Harpoon anti-ship missile launchers (which were installed across the RAN vessels from 2005 onwards), and a second Mark 41 launcher (which has not been added). The Australian Anzacs use a Sikorsky S-70B-2 Seahawk helicopter; plans to replace them with Kaman SH-2G Super Seasprites were candled in 2008 due to ongoing problems.
Perth was laid down at Williamstown, Victoria, on 24 July 2003. The ship was assembled from six hull modules and six superstructure modules; the superstructure modules were fabricated in Whangarei, New Zealand, and hull modules were built at both Williamstown and Newcastle, New South Wales, with final integration at Williamstown. She was launched on 20 March 2004, and commissioned into the RAN on 26 August 2006 in Fremantle, Western Australia (the closest port to the ship's namesake city). Perth was the final Anzac class ship to be constructed.

Famous quotes containing the words design and/or construction:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
