Speaking of tensions with China… PM Scott Morrison yesterday announced a $1 billion plan for Oz to work with the US to build our own guided missiles. They’re the type whose course can be altered during flight. The aim is to bulk up our self-defence capabilities amid what the PM politely called a “changing global environment”. While a home for the project hasn’t been determined, the big defence manufacturing outfits like Raytheon and BAE Systems are on the list as potential partners. In November last year, an Aussie-US collab to develop and test a hypersonic cruise missile was announced. They’re the ones that go really far, really quickly. All up, the government is forecast to spend $270 billion on defence over the next decade.
