RAN Weapons electrical engineering officer lieutenant commander Mark Williams said that the Nulka is a hovering rocket decoy system that is primarily used against anti-ship missiles.
Williams added: “It forms a part of our layered defensive capability in the maritime environment.
“During the testing of new components, we aimed to increase the tactical effectiveness of the Nulka against anti-ship missiles.”
The trials were conducted in order to demonstrate the RAN’s ability to fight and win during sea-based conflicts.
RAN’s missile defence capabilities were tested using a civilian aircraft and included an under-slung Nulka payload carried by helicopter, as well as a Learjet aircraft that simulated an incoming anti-ship missile.
The Nulka enhancements have been trialled in collaboration with Australia’s defence industry partners as part of this year’s Ocean Explorer exercise, which represents one of the RAN’s largest fleet training activities.
Williams further added: “We used fast jets fitted with missile simulators, and helicopters carrying a Nulka payload to generate a realistic missile engagement scenario.
“The more effective Nulka is, the more enhanced will be the defence of our largest ships, the Landing Helicopter Docks.”
RAN collaborated with the Defence Science and Technology Group, Air Affairs Australia and Kestrel Australia in order to carry out the tests.
The Nulka active missile decoy has been developed by the US in cooperation with Australia.
Aerojet was responsible for the manufacture of the system’s rocket motor.
The Nulka system features advanced flight vehicle guidance and control techniques, in addition to upgraded radio frequency (RF) electronic technologies.
