AUKUS Five-Year Review: Gains, Gaps, and the Road Ahead
By Drooid · · How we work
Core Event – Five Years After the AUKUS Announcement
In September 2021 the United States, the United Kingdom and Australia launched the AUKUS partnership, a 30-year security pact built around two pillars: a nuclear-powered submarine program (Pillar I) and joint development of advanced defence technologies (Pillar II). Five years on, senior architects of the deal—including former U.S. deputy secretary of state Kurt Campbell, former Australian defence secretary Greg Moriarty and former UK national-security adviser Sir Stephen Lovegrove—have said the initiative is “on track” but still faces “major challenges” such as workforce shortages and submarine-construction delays.
Background & Context
The original plan called for Australia to acquire at least three U.S. Virginia-class submarines in the 2030s and later build its own “AUKUS-class” boats. Pillar II covers under-sea, quantum, AI, cyber, hypersonic and electronic-warfare capabilities. The partnership survived multiple leadership changes and has been assessed by CSIS as having moved beyond its early “institution-building” phase to a stage of “considerable” infrastructure.
Data & Statistics
| Metric | Figure | Source |
|---|---|---|
| Total projected AUKUS cost (30 years) | A$268 billion – A$368 billion | The Conversation |
| Contingency allocation (? 1/3 of total) | A$122.9 billion (may not be spent) | The Conversation |
| Infrastructure spending | A$12 billion (Henderson Defence Precinct); A$8 billion (HMAS Stirling expansion) | The Conversation |
| Australian contributions to overseas shipyards | US$2 billion (? A$2.8 billion) in three instalments; US$1 billion (? A$1.4 billion) pledged over the next decade | The Conversation |
| Projected Australian AUKUS spending | ? A$2.2 billion per year for the first four years, rising to > A$8 billion annually thereafter | The Conversation |
| U.S. submarine production rate (COVID era) | 1.1 – 1.3 boats per year (down from 1.9 per year 2016-19) | The Conversation |
| Target production to meet U.S. + Australian demand | 2.33 boats per year; U.S. Navy aims for 2 boats per year by 2032 | The Conversation |
Official Statements & Responses
Campbell argued that AUKUS forced the United States to confront a “profoundly lacking” submarine-maintenance and construction capacity, but expressed confidence the partnership will eventually overcome those gaps. Moriarty highlighted the “enormous investment” made by the Trump administration in the submarine industrial base and noted steps taken to accelerate shipbuilding capability.
A congressional committee has asked the U.S. Navy to explain how the proposed “Trump-class” battleship program will avoid delaying the nuclear-powered submarines needed for AUKUS, underscoring lingering concerns about resource competition.
Conflicting Reports & Gaps
Australia lacks a single, publicly available ledger that itemises all AUKUS-related spending, making it difficult to verify the exact amount already expended. Likewise, public records do not consistently disclose the current U.S. submarine production rate, leaving analysts to rely on estimates rather than definitive data.
What’s Next
The Submarine Rotational Force-West (SRF-W) is scheduled to begin regular U.S. and U.K. submarine visits to HMAS Stirling in Perth from 2027, providing Australian personnel with hands-on maintenance and operational experience. The first U.S.-built Virginia-class submarine is expected to arrive in Australia in the early 2030s, followed by the first domestically co-developed AUKUS-class boat at least 15 years later. Ongoing investment in shipyard infrastructure and workforce training will be essential to meet production targets and sustain the broader strategic aim of deterring regional threats.
