‘We’ve been very clear in private’ what US needs from AUKUS: Pentagon

The Pentagon's top policy official confirmed on August 13, 2026, that the United States has communicated clearly with the Australian government about its expectations under the AUKUS security pact, emphasizing the strategic significance of the HMAS Stirling base in Western Australia. Elbridge Colby, Undersecretary of War for Policy at the U.S. Department of Defense, stated during a press briefing that the U.S. has maintained a consistent dialogue with Australia regarding the responsibilities outlined in the tripartite agreement involving the U.S., the United Kingdom, and Australia. This comes amid ongoing discussions over the deployment of U.S. nuclear-powered submarines at the facility, which has sparked debate within Australian politics. Colby, who previously expressed skepticism about AUKUS during his time in the Trump administration, noted that the Pentagon has been satisfied with the progress made since the agreement underwent a comprehensive review last year. He highlighted the critical role of the Submarine Rotational Force-West (SRF-West), which involves the rotation of U.S. and eventually Australian nuclear-powered submarines at HMAS Stirling. Colby described the base as “tremendously important” and emphasized that it benefits both the U.S. and Australia. Recent controversy surrounded the SRF-West initiative following comments from Australia’s Defence Industry Minister, Pat Conroy, who initially suggested that U.S. submarines would be stationed at the base for only five years until 2032. However, Conroy later corrected himself, stating that the U.S. presence would be “ongoing.” The issue centers around whether nuclear-armed submarines could operate at HMAS Stirling, considering Australia’s commitment to maintaining a nuclear-weapon-free zone under the Treaty of Rarotonga. When questioned about the potential deployment of nuclear-armed submarines beyond 2032, Colby avoided providing a direct response. Instead, he indicated that the U.S. and Australian governments share a “very tight discussion and a very clear understanding” regarding AUKUS, though he refrained from disclosing specifics of these discussions. Colby reiterated that the U.S. has been transparent with Australia about its expectations, aiming to establish a stable framework for achieving the shared objectives of the alliance. The U.S. defense secretary, Pete Hegseth, has appointed Colby as his undersecretary for policy, underscoring the importance of maintaining close coordination with Australia. Colby acknowledged the growing momentum in Australia toward fulfilling its commitments under AUKUS, describing Australia as “no better ally” than the U.S. in the context of regional security. The U.S. faces challenges in meeting its submarine production goals, with the current rate of building Virginia-class nuclear submarines lagging behind the required pace. The Pentagon has acknowledged that the annual production rate stands at approximately 1.1 to 1.2 submarines per year, far below the target of 2.33 units necessary to support AUKUS obligations. Despite this shortfall, Colby expressed confidence in the ability of both nations to address these issues, stating that the U.S. would continue to push forward with its targets while expecting similar efforts from Australia. As the AUKUS partnership continues to evolve, the strategic implications for the Indo-Pacific region remain significant. Both the U.S. and Australia are committed to strengthening their military cooperation, particularly in areas such as naval capabilities and regional stability. The ongoing dialogue between the two countries reflects a mutual recognition of the necessity for robust defense collaboration to counter emerging threats and maintain a balanced power structure in the region.
