Rooted in Australia's defence history, Nulka has become one of the nation’s biggest defence success stories. Nulka – a hovering rocket which lures incoming missiles away from ships to protect their crews – is made in Australia with an Indigenous name meaning “be quick”. It is currently deployed on more than 140 Australian, American and Canadian warships. More than 1,000 Nulka systems have been manufactured earning more than $1 billion for the Australian economy.   Join Lily Serna as she meets the people behind the development and daily operation of this ‘ghost missile’.
