A timeline of the sub’s history and the submarines that have been built since its first flight in 1961.
The timeline includes: 1963 – The Submarine Group submersible is commissioned at the Royal Australian Navy’s Sydney naval base.
1964 – The first submersibles are delivered to the Royal Navy, the Australian Submarine Force.
1965 – The Australian Submariners Training Group is established.
The training organisation is based at Sydney Naval Base.
1966 – The Royal Australian Subs (RAS) is created.
The RAS is based in Darwin.
1968 – The RAC conducts a series of tests and inspections of the first sub’s propulsion system and a range of new technologies.1969 – The submarine fleet is increased from 16 to 20 submarines by the RAS and the RAC.
1972 – The subs reach their final operational capability with the Australian Navy.
1973 – The fleet is upgraded with new technology and equipment.
The Submariner Group is decommissioned.
Submarine fleet operations in the next decade The fleet was upgraded from the existing 32 to a more modern fleet of 60 submersibles.
This was done to provide an effective deterrent to other countries, the RAAF said.
It is the first time the fleet has been fully modernised.
The RAAF also upgraded the fleet’s propulsion, communication and navigation systems, as well as adding new communications and radar systems to the fleet.
These included a new communications system that allows the RWS to communicate with the subs’ air and sea sensors, as they are no longer able to transmit their signals through conventional air and water.
The network also features a new remote communications link between the RWA and the submarine fleet.
The new system is designed to give the RAs operational control of the subs and the ability to send and receive commands from them, including the ability for the RAW to request the use of the submarine for a specific mission.
This will be the first capability for the fleet to be operational using a fully operational capability.
The submarines will continue to operate from the Royal Adelaide Naval Base, in South Australia, and at the Darwin Naval Base in Darwin, Australia.
