SIA Welcomes the Acting Prime Minister’s Launch of the 2026 National Defence Strategy and Integrated Investment Program
The Submarine Institute of Australia (SIA) welcomes the release of the 2026 National Defence Strategy (NDS) and the 2026 Integrated Investment Program (IIP) by the Acting Prime Minister and Minister for Defence, the Hon. Richard Marles MP. These foundational documents provide critical continuity, building upon the frameworks established in 2024 to strengthen Australia’s maritime security.
The 2026 NDS reinforces the Strategy of Denial adopted in 2024 with increased self?reliance, and a more robust sovereign industrial base. Notably, the Strategy acknowledges the pivotal importance of undersea warfare to Australia’s deterrence posture, with submarines and advanced undersea systems recognised as some of the nation’s most strategically valuable assets.
The SIA is pleased to note the progress achieved and the ongoing commitment to the acquisition of conventionally armed nuclear-powered submarines. Commitments of long-term investment, reform to enhance delivery, partnerships to ensure a skilled and integrated national workforce, and continuation of efforts to involve Australian industry in global supply chains are timely and welcome.
While much public discussion of submarines focus on the AUKUS program, the SIA is pleased with the Government’s commitment to current and near-term undersea capability requirements. This includes continued investment in the current submarine force - including investment in the Collins class submarines to ensure they remain a powerful strike and deterrent capability and operationally viable until 2040. The Government’s support for undersea warfare requirements and uncrewed maritime systems, such as Ghost Shark, Speartooth, and Bluebottle, is also welcomed by the SIA.
SIA President, Michael Fitzgerald, commented:
“The 2026 NDS and IIP recognise that Australia’s undersea capability is fundamental to national security and prosperity. Submarines—and the broader undersea warfare ecosystem that supports and supplements them—provide Australia with a capability to deliver impactful projection to deter conflict and coercion. The SIA strongly supports the Government’s commitment to both the current and future sub-sea capability.”
The SIA looks forward to continuing its constructive engagement, fostering informed debate with Government, Defence, industry, academia, and international partners.
