The investment is made in the context of the Aukus-Pact, a collaboration of the United States, the United Kingdom and Australia. An important point in this is a fleet of core submarines for Australia. With the Pact, the countries seem to want to arm themselves mainly against the growing influence of China in the region. The Australian Defense Minister Richard Marles said on Sunday that the US can use the facilities in the future as part of the Aukus agreements.
Australia, which now has no facilities for the maintenance of core submarines, wants to purchase at least three American submarines from the Virginia class within fifteen years and eventually start building his own submarines in the facilities in Perth. The plans announced are part of a defense project that will last twenty years. According to Marles, the total costs can go up to 25 billion Australian dollars (14 billion euros).
