Building Depth: How Indo-Pacific Allies Are Hardening for a Long Contest
In the fast-paced world of the Indo-Pacific, headlines often grab attention with news of carrier movements, missile tests, and coast guard confrontations in the South China Sea. However, a closer look at the recent activities of key allies in mid-October 2026 reveals a more significant and consequential story unfolding.
Japan: Depth Through Energy, Industry, and Unmanned Systems
Japan stands out as a prime example of a nation taking a holistic approach to building resilience. In a move to strengthen and diversify the country’s energy supply chains, the Japanese cabinet approved three bills on October 13. These bills aim to reduce dependence on the Strait of Hormuz for crude imports, with subsidies for refiners and government support for tanker insurance and pipeline investments in the Middle East.
Additionally, Japan is investing in its defense industrial base by building a new hull-block manufacturing plant on Chōshū-Dejima island. This investment, supported by government funds, highlights the shift towards viewing shipbuilding capacity as an economic-security asset.
Looking towards the future, Japan is also focusing on developing unmanned maritime systems, with plans to establish a defense base in Kure for research, production, and maintenance facilities. This move emphasizes the importance of building, repairing, and upgrading unmanned systems close to operational areas for enhanced strategic depth.
South Korea: Depth Through Industry, Dispersal, and Manpower
South Korea is strategically building depth along three key lines. Firstly, the nation is prioritizing industrial advancements, with increased funding for defense procurement and production. Noteworthy reforms include faster fielding of systems and a shift towards continuous upgrades to keep pace with evolving threats.
Operationally, South Korea is moving away from traditional large command posts towards a more dispersed training approach across the peninsula. General Xavier Brunson’s emphasis on mobility, resilient command, and learning from combat experiences in Ukraine underscores the importance of adaptability and readiness.
On the manpower front, South Korea is addressing demographic challenges by considering changes to service exemptions and planning for a potential decline in the military manpower pool. These efforts align with the nation’s push towards autonomy and unmanned systems in response to strategic constraints.
Taiwan: Defending the Center, Distributing the Edge
Taiwan’s initiatives focus on enhancing resilience from its capital outward. Plans to expand the Military Police Command and equip troops with counter-drone capabilities demonstrate a proactive approach to safeguarding critical infrastructure against potential threats.
At sea, Taiwan is exploring the integration of reusable, multi-mission autonomous surface vessels to enhance maritime capabilities. Emphasizing co-production and local maintenance, Taiwan’s strategy aims to build a sustainable and effective unmanned force.
India: Sovereign Control of Connectivity
In India, discussions around sovereignty and connectivity highlight the nation’s focus on ensuring independent control over critical capabilities. Debates on reliance on foreign operators like Starlink underscore the significance of connectivity as a warfighting capability and a matter of national sovereignty.
Australia: A Cautionary Note
Australia’s decision to sell the Williamstown shipyard raises questions about the strategic management of shipbuilding capacity. Contrasting with Japan’s approach of viewing shipbuilding as an economic-security asset, Australia’s handling of the shipyard as a property transaction underscores the importance of strategic attention to infrastructure ownership and location.
Implications for the Alliance
The recent developments among allies in the Indo-Pacific underscore the shift towards prioritizing resilience, operational adaptability, and industrial depth in strategic planning. As allies invest in building their own depth, there is a growing opportunity for collaboration through co-production, shared sustainment, and interoperable autonomy to enhance collective security in the region.
While headlines may capture attention with visible events, the true significance lies in the strategic decisions being made to strengthen alliances and ensure readiness for the challenges ahead.
