The Collins Class

The characteristics and range of Collins class submarines have been tailored specifically for its defence and two-ocean surveillance role in the Royal Australian Navy. Designed to be as quiet as advanced technology can achieve, Collins class submarines have been developed from five generations of submarines designed and built by the Swedish Navy.

One of the first submarines to be totally designed by computers, these submarines boast a vast range of features. They include a high performance hull form, highly automated controls, low indiscretion rates, high shock resistance, efficient weapons handling, and an optional air-independent propulsion system.

The submarines move silently on electric power supplied by banks of new-technology lead-acid batteries. The batteries are charged by three on-board diesel generator sets.

The sophisticated combat system, which gathers its intelligence from its sensors, computes the input and then launches and directs weapons, is an advance on any system currently available.  Referred to as AN/BYG-1(v)8, it is the result of an Armaments Cooperative Program (ACP) between the navies of Australia and the US.

Each ship has been named after a distinguished former member of the RAN, some of whom have made the ultimate sacrifice for their country.

Based at HMAS Stirling in Western Australia, they are a formidable element in Australia's defence capability.

Project Development

The Collins Class project was established by the Royal Australian Navy (RAN) in 1982.

Replacing the RAN's Oberon Class, the new design was required to meet the unique needs of the Navy, which were dictated by, among other things, Australia's geographic location.

The new submarines would be required to:

  • travel great distances;
  • operate in varying environments;
  • have state-of the-art weapons systems; and
  • perform traditional submarine functions using the most advanced technology available.

The submarines would also be required to protect Australia through their very existance, acting as a deterrent to enemy forces.

It was decided that large conventional submarines would be acquired.  The Collins Class submarines are the second largest non-nuclear powered submarines in the world.

In 1987,  the newly formed Australian Submarine Corporation (now ASC Pty Ltd), began the task of designing and building the most sophisticated conventional submarine in the world.

Construction of the first Collins Class submarine, HMAS Collins, was begun in 1990 and delivered it to the RAN in 1996.  The sixth and final boat, HMAS Rankin, was delivered to the RAN in 2003

 

Submarine Construction

Submarine Construction
The construction of the Collins Class submarines was an unprecedented feat of engineering, design and logistics in Australia.

 
The project required specification, integration and installation of equipment and material from over 150 major contractors and hundreds of smaller suppliers.  Most of the submarine modules were constructed off-site and then shipped to us for integration.

Key parameters for equipment included electrical power, cooling, noise, shock resistance, weight and electromagnetic characteristics, all under rigorous configuration management as data was distributed between the various suppliers during the design phase.

Submarine Outfitting Statistics
 
Piping     23,500 metres
Major cable lengths  7,000
Cable connections   200,000
Cable     75,000 metres
Batteries    400 tonnes
 
A completed submarine is a system of systems.  A Collins Class submarine contains 108 integrated systems which are linked structurally, mechanically, electrically, hydraulically, pneumatically and electronically.

All of these systems need power and cooling, and many need to communicate with each other in order to achieve full operational capability.


Technical Documentation
 
Over 33,000 drawings and 5,000 work orders were produced before construction of the Collins Class submarines could begin.  Once work started, each submarine took 2.5 million hours to assemble.

There are an estimated 350,000 individual technical documents associated with the Collins Class submarines, including:
 

 
Design drawings  70,727
Parts lists   46,717
Specifications    42,865
