“奥库斯”核潜艇遇阻，澳大利亚或改买B-2隐形轰炸机？

Group 1 - The AUKUS trilateral security pact, signed by the US, UK, and Australia, involves a $368 billion investment to assist Australia in building a nuclear submarine fleet to counter perceived threats from China, but its implementation is increasingly doubtful [1] - Australia is currently paying the US and UK for the AUKUS agreement, with approximately $4.6 billion already received by the US for enhancing its submarine construction capabilities, and an additional $4.8 billion expected by the UK over the next decade, yet Australia has not received any substantial returns [1] - Experts indicate that the US is unlikely to provide Australia with Virginia-class submarines due to its own shortages, with a backlog of 12 orders and an average production rate of only 1.2 submarines per year, which is insufficient to meet both US and Australian demands [2] Group 2 - The UK is also facing challenges in meeting Australia's submarine needs, with its submarine fleet described as "chaotic" and "precarious," leading to a significant shortage of operational submarines [2] - Defense experts suggest that Australia should consider acquiring B-2 stealth bombers instead of nuclear submarines, as they could provide a more cost-effective and flexible strategic strike capability in the Indo-Pacific region [3] - The Chinese government has expressed opposition to the AUKUS pact, citing concerns over increased nuclear proliferation and an arms race in the region [3]
