Development and Design
The proposal for a new class of submarines to replace the Oberon class of diesel-electric submarines began in July 1978, when the RAN director of submarine policy prepared a paper detailing the need to start considering a replacement for the ageing Oberons. The paper also raised the suggestion that the majority of the submarines be constructed in Australia and that the number of submarines be increased beyond the six Oberons. Building the submarines in Australia was initially met with reactions predicting an impossible task because of the poor state of the Australian shipbuilding industry, and Australian industry in general, although campaigning by several figures in Australian industry who thought it could be done came to the attention of those spearheading the project to design the Oberon class replacement, and led to the view that it was both possible and feasible. The campaign to build submarines in Australia was also met with support from the Australian Labor Party and several trade unions.
The proposal was accepted by the defence operational requirements committee in August 1978, and the project was given the procurement designation of SEA 1114. Approval for the development phase of the project was given in the 1981–82 federal budget. The RAN had four main requirements: that the submarines were tailored to operating conditions in the Australasian region; that they be equipped with a combat system advanced enough to promote a long service life; that appropriate and sustainable infrastructure be established in Australia to construct the boats, then provide maintenance and technical support for their operational lifespan, and that the submarines were capable of peacetime and emergency operations in addition to their hunter-killer role. Ten submarines were envisioned, a number which was revised to between four and eight boats by the start of 1983, and later settled on the acquisition of six submarines, with the option to order two more.

Famous quotes containing the words development and, development and/or design:
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
“Every new development for the last three centuries has brought men closer to a state of affairs in which absolutely nothing would be recognized in the whole world as possessing a claim to obedience except the authority of the State. The majority of people in Europe obey nothing else.”
—Simone Weil (1909–1943)
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
