A return to Pacific Command
On 16th June, the US Department of War announced that its Indo-Pacific Command (USINDOPACOM) would revert to its previous name of US Pacific Command (USPACOM). While framed as a restoration of its historic title, the timing raises broader strategic questions. This largest and oldest US combatant command was referred to as USPACOM from 1947 until 2018, when its name was changed to recognise its geographic responsibilities and the increased connectivity between the Pacific and Indian Oceans.
Two aspects of this decision to drop ‘Indo’ from the combatant command’s title are important to note:
- The name change does not affect the geographic responsibilities of the command, which continue to encompass both oceans.
- The Pacific Command name will be a secondary title, whereas US Indo-Pacific Command will continue to be used for formal statutory references in the absence of congressional approval of a name change (which to date has not been sought).
A scan of social media suggests the rationale for reverting the name resonates with many who have been affiliated with USPACOM in the past. The key question is not what changed, but why now? After all, the logic that led to the first Trump administration decision in 2018 to change the name to Indo-Pacific Command remains, making this a notable reversal.
Why change the name now?
While this apparent change of mind might seem puzzling, it should be remembered that the 2018 announcement was made by then Defense Secretary Jim Mattis. After resigning from that role in December of 2018, General Mattis became a prominent critic of President Trump – which could help explain how the current Trump administration views the INDOPACOM title.
Commentators point to three likely reasons for the reversion, with the first one being a return to USPACOM’s history – the rationale given in the announcement. A second reason may be Secretary Hegseth’s intent to stamp authority through branding changes, in the same way as the Department shifted from Defense to War. This reason is consistent with the notion of a reversal of a decision made by an estranged official.
A third reason is to align more with the US’ 2026 National Defense Strategy (NDS), which emphasises putting US interests first through a more focused approach to the threats that the nation faces.
Strategy over symbolism
Overall, the explanation that best fits the available evidence is that the name change is driven more by strategy than heritage. Proximity is important, given the US west coast is on the Pacific, as is Hawaii, Alaska, and several US territories. While the 2026 NDS distances itself from an isolation approach to homeland defence, it is clear that US national security interests demand greater primacy of the Pacific Ocean than the Indian Ocean.
[T]he name change is driven more by strategy than heritage.
A US emphasis on the Pacific Ocean is consistent with the expectation under the Trump administration that allies and partners should take greater responsibility for their security. Under this approach, it would be reasonable for the US to take a greater lead in the Pacific and expect other nations to contribute more in the Indian Ocean area – which may be a message arising from the Indo name drop.
Strategic signals for China and India
Two countries that are specific objects for such messaging are China and India.
The great power contest between the United States and China is primarily focused on the Pacific Ocean, with Taiwan, the South China Sea, and the East China Sea sources of potential conflict. Taiwan was not mentioned in the 2026 NDS, perhaps in the interest of strategic ambiguity. Yet clearly any forceful unification of Taiwan remains the subject of military planning within USPACOM.
The 2018 rebranding to USINDOPACOM was part of a broader recognition of the interconnected Indian and Pacific Oceans, acknowledging India as a central actor in the balance of power. The 2026 reversion coincides with a shift away from the use of the Indo-Pacific term within the US government, and may signal that India no longer enjoys the privileged position it once held in US strategic thinking.
India remains an important security partner to the US – but the relationship with India (as with other partners) appears increasingly less strategic and more transactional. It also comes at a time when the US has sought to leverage relations with Pakistan to resolve conflict with Iran. As Ken Moriyasu points out, a de-emphasis of the relationship with India gives the US greater flexibility to work with Pakistan, whose relevance also relates to China’s western pivot.
What does this mean for the Quad and US Allies?
The US transactional approach to relationships may also be of concern to other key allies in the Indo-Pacific, such as Australia and Japan. Together with India, these nations have cooperated with the US on maritime security and dialogue for the past decade under the Quad partnership.
While dropping the Indo from Pacific Command’s title has generated speculation about the future of the Quad, commentators and US officials assert that there should be no impact on the relationship. Indeed, the growing remit and cooperative initiatives under the Quad should ensure that it remains strong.
Australia’s relationship with USPACOM is also resilient, with high levels of integration including senior embedded ADF staff in the headquarters. This is reflective of the close and enduring alliance between Australia and the US, which will continue to underpin Australia’s national security architecture – despite the occasionally unpredictable and transactional approach of the Trump administration.

Ultimately, the Indo drop reflects a subtle but meaningful shift away from a broader Indo-Pacific focus toward a stronger US emphasis on the Pacific.
Implications for Western Australia and AUKUS
For Western Australia, a key question is whether the name change has any impact on the maritime cooperation with the US Navy that supports Indian Ocean security, and thus our national security. Such cooperation is crucial to the AUKUS pathway, which requires rotations of submarines through HMAS Stirling.
Based on the available information, the name change does not represent a material risk in this regard, certainly not in comparison to the broader challenges facing the AUKUS program. For Australia, it reinforces a clear message that while US engagement remains strong, its allies will be expected to do more to shape and secure the wider region.
