The MU90 has been successfully supported by Thales Australia’s facility in Rockingham, Western Australia since it entered into service with the Navy in 2013.

The renewal of the in-service support contract for 3 years will be delivered utilizing 100% Australian Industry Capability (AIC), and will directly support jobs with Thales in Western Australia, and more in Thales’s local WA supply chain.

Over the past decade, Thales has built a sovereign industrial capability in WA to ensure Australia has the capability to fully support the MU90 torpedo.

The MU90 is an advanced lightweight anti-submarine torpedo of the 3rd generation[3] developed by France and Italy for navies of France, Italy, Germany, Denmark, Australia and Poland. Designed and built with the most advanced technology, the weapon is a fire-and-forget type, conceived to cope with any task any environment capability requirements and meet the ASW (Anti-Submarine Warfare) operational needs of the 21st century.

The MU90 has been designed to counter any type of nuclear or conventional submarine, acoustically coated, deep and fast-evasive, deploying active or passive anti-torpedo effectors. The torpedo can be deployed by any type of platform such as surface vessels, fixed or rotary-wing aircraft, or missiles. Pre-arrangements to cope with Submarine-Launched Anti-Air Missiles (SLAAM) have been already incorporated into the system.

The MU90 torpedo is 323.7mm ‘NATO Standard’ calibre, weight 304 kg and has a length of 2850mm long. The torpedo is powered through an Aluminium-Silver Oxide sea water battery using dissolved sodium-dioxide powder as electrolyte and incorporating an advanced closed-loop electrolyte re-circulation system, the torpedo is propelled by an electronically controlled high-RPM brush-less motor driving a skewed multi-blades pumpjet propulsor allowing a continuously variable torpedo speed automatically selected by the tactics of the weapon according to the scenario, the environment and the operational phase.

The Mu-90 torpedo operates without any speed degradation and any limitation of salinity and temperature in water depths in excess of 1,000 m and as shallow as 25 m, retaining navigation capability up to 3 m. The advanced acoustic seeker features multi pre-formed transmission and reception beams.
