Contracts for the design of the Main Storage Batteries Stages 1 and 2 for the Attack Class submarines have been awarded, another major milestone for the program.

PMB Defence, based in Adelaide and Sunlight, based in Greece have been contracted to provide design, prototyping and qualification activities for the Main Storage Batteries. Both organisations will provide Naval Group with the data necessary to select one as the preferred MSB design for the Attack Class program in 2022.

The Main Storage Batteries are responsible for supplying power to the propulsion system of the submarine and to other equipment on-board the ship. They directly impact the safety of the submarine when diving, making them a critical piece of equipment for the platform.

Minister for Defence, Senator the Hon Linda Reynolds CSC said the design of the main storage batteries is one of the “Top 5” critical equipment items to the overall design of the Attack class submarine.

The Attack-class submarine is a future class of submarines for the Royal Australian Navy based on the Shortfin Barracuda proposal by French shipbuilder Naval Group (formerly known as DCNS) to replace the Collins-class submarines. The class will enter service in the early 2030s with construction extending into the late 2040s to 2050. The Program is estimated to cost $50 billion and will be the largest, and most complex, defence acquisition project in Australian history.

Further contracts will be awarded for the manufacture of the batteries in Australia following selection of the preferred battery design.
