Collins Class Submarine - Problems During Construction and Trials

Problems During Construction and Trials

The Collins-class submarines experienced a wide range of problems during their construction and early service life. Many of these were attributed to the submarines being a new, untested design, and were successfully addressed as they were discovered. Most systems and features worked with few or no problems, while the boats' maximum speed, manoeuvrability, and low-speed submerged endurance were found to exceed specifications. The ship control system, which during development had been marked as a major potential problem, functioned beyond positive expectation: for example, the autopilot (which aboard Collins was nicknamed 'Sven') was found to be better at maintaining depth during snorting than most helmsmen.

However, problems with the combat system, excessive noise, and engine breakdowns were recurring and appeared across the entire class. These and other shortcomings were often made harder to solve by disagreements between Kockums, ASC, Rockwell, the RAN, and the Australian Government over the nature of problems, their causes, and who was responsible for solving them. Media reporting of the problems during the mid-1990s was often negative and exaggerated, creating poor public perception. This was aided by politicians, who used the shortcomings to politically attack the Labor Party and Kim Beazley, particularly after Labor was defeated by the Liberal-National Coalition in the 1996 federal election, and Beazley became Leader of the Opposition. During the mid-1990s, it was recommended on several occasions that the submarine project be abandoned, and the completed submarines and incomplete hulls be broken up for scrap.

Following the McIntosh-Prescott Report, which indicated the long-term faults with the class that still required solving, successful efforts were made to bring the submarines to operational standard. As part of this, a public relations plan was implemented to provide up-to-date information on the submarines to the media, to improve the public perception of the class by providing factual information on the status of the project and responding to queries and incidents. This same period saw the dispelling of the idea, widely-held within the RAN, that the Collins-class boats would be like any other vessel previously ordered by the RAN: in service with another navy, well tested, and with all the problems solved before they entered Australian hands. The RAN began to realise that as the parent navy for the class, they had a greater responsibility than normal in ensuring that the boats were at an operational standard.

Famous quotes containing the words problems, construction and/or trials:

    It’s so easy during those first few months to think that the problems will never end. You feel as if your son will never sleep through the night, will always spit up food after eating, and will never learn to smile—even though you don’t know any adults or even older children who still act this way.
    Lawrence Kutner (20th century)

    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)

    On the whole, yes, I would rather be the Chief Justice of the United States, and a quieter life than that which becomes at the White House is more in keeping with the temperament, but when taken into consideration that I go into history as President, and my children and my children’s children are the better placed on account of that fact, I am inclined to think that to be President well compensates one for all the trials and criticisms he has to bear and undergo.
    William Howard Taft (1857–1930)
