AUKUS五年进展评估：澳大利亚核潜艇计划面临时间与产能挑战

美英澳三国2021年9月15日宣布的AUKUS安全伙伴关系已运行五年，该倡议旨在加强印太地区防御能力。1根据进展评估，澳大利亚在这一30年"最优路径"计划中投资估计为2680亿至3680亿澳元，其中约1229亿澳元被设为应急资金。1在具体基础设施建设上，Henderson国防基地投资120亿澳元，HMAS Stirling扩建投资80亿澳元，Osborne核潜艇建造船厂投资85亿澳元。1美国方面投入20亿美元，英国方面承诺24亿英镑。1

核潜艇交付时间面临显著延迟。澳大利亚至少需要6年后才能收到首艘美制弗吉尼亚级潜艇，至少15年后才能收到首艘AUKUS级潜艇。1这些延期与美国的生产能力密切相关。美国潜艇生产率自疫情后平均为1.1-1.3艘每年，但要满足该计划需要达到2.33艘每年的生产速度。1美国海军预计2032年才能达到2艘每年的生产速度。1更深层的挑战在于，美国海军预计需要66艘潜艇应对中俄威胁，但实际舰队数量正在下降。1

The AUKUS security partnership between the United States, United Kingdom, and Australia, announced on September 15, 2021, by President Biden, Prime Minister Johnson, and Prime Minister Morrison, has committed significant resources to advancing naval capabilities in the Indo-Pacific region 1. Australia's 30-year "optimal pathway" plan involves estimated investments ranging from AUD 268 billion to AUD 368 billion, with approximately AUD 122.9 billion designated as contingency funding within the higher estimate 1. These funds are being directed toward critical infrastructure projects, including AUD 12 billion for Henderson Defence Base, AUD 8 billion for HMAS Stirling expansion, and AUD 8.5 billion for the Osborne nuclear submarine shipyard 1. The United States has committed USD 2 billion to the initiative, while the United Kingdom has pledged GBP 24 billion 1.

Despite substantial investment, the timeline for acquiring submarines remains extended. Australia will not receive its first Virginia-class submarine from the United States for at least six years, and will need to wait at least 15 years for the first AUKUS-class submarine 1. These delays reflect broader production constraints, as U.S. submarine manufacturing has averaged only 1.1 to 1.3 vessels annually since the pandemic, while meeting the partnership's objectives requires an output of 2.33 vessels per year 1. The U.S. Navy projects achieving a production rate of two vessels per year by 2032 1. These challenges compound existing defense concerns, as the U.S. Navy requires 66 submarines to address threats from China and Russia, yet its current fleet size is declining 1.
