Building Depth: How Indo-Pacific Allies Are Hardening for a Long Contest

The headlines in the Indo-Pacific tend to focus on the visible: carrier movements, missile tests, coast guard confrontations in the South China Sea. But a look at what key allies were actually doing in a single week in mid-October 2026 reveals a different and, in my view, more consequential story.

Japan, South Korea and Taiwan, with India and Australia providing instructive contrasts, are building strategic depth and resilience. They are not simply buying more platforms. They are identifying their single points of failure and then paying, often quietly and at real expense, to remove them.

The common thread is dependence. It might be dependence on a maritime chokepoint, a shipyard, a pool of conscripts, a satellite operator or a command post that can be found and struck. The allies that recognize these dependencies and act on them are building the kind of depth that matters in a long contest with China. Those that do not are accepting risk they may not fully appreciate.

Japan: Depth Through Energy, Industry and Unmanned Systems

Japan offers the most comprehensive example of a government treating resilience as a whole-of-nation enterprise.

On 13 October, the Japanese cabinet approved three bills to strengthen and diversify the country’s energy supply chains, according to Jiji Press via Nippon.com. The first subsidizes refiners for the extra cost of buying crude through routes outside the Strait of Hormuz. The second has the government step in on tanker insurance when overseas reinsurers will not. The third allows the state energy agency JOGMEC to invest in and guarantee pipelines in the Middle East that bypass the Strait.

The scale of the exposure explains the urgency. Japan sourced 94 percent of its crude imports from the Middle East in 2025, and 93 percent of those shipments passed through Hormuz, as reported by Hydrocarbon Processing. The insurance backstop is being extended beyond crude to oil products and LNG, according to S&P Global.

What is striking is the design. The subsidy is funded by levies on the importers themselves, with JOGMEC administering grants against government-certified procurement plans. This is not a one-time bailout. It is a standing mechanism that puts a price on chokepoint dependence and rewards the companies that reduce it.

The same logic now extends to the defense industrial base. On 2 October, Mitsubishi Heavy Industries signed a contract with Shimonoseki City to build a new hull-block manufacturing plant on the artificial island of Chōshū-Dejima, according to J-Defense News. The investment is about ¥100 billion, with up to ¥40 billion in government support. That support became possible after the transport ministry certified Mitsubishi Shipbuilding’s supply-security plan under the Economic Security Promotion Act, which now lists hulls among the critical goods it covers.

Put simply, Tokyo has defined shipbuilding capacity as an economic-security asset. That is a significant shift in how a democracy thinks about the industrial foundations of maritime power.

The third Japanese initiative points toward the future force. At Kure, where the battleship Yamato was built, Japan’s acquisition agency ATLA has invited private companies to set up research, production and maintenance facilities on a planned 140-hectare integrated defense base, as reported by Asian Military Review. Planned functions include the manufacturing, maintenance and testing of unmanned surface and underwater vehicles, alongside naval logistics, fuel and sustainment. ATLA has said it prefers companies engaged in international co-development, with expressions of interest due by 30 October and selections expected around May 2027.

This is the right model. Unmanned maritime systems deliver strategic depth only if they can be built, repaired, upgraded and regenerated close to where they will operate. Kure puts the factory, the test range, the maintenance depot and the operating force on the same waterfront, and it explicitly invites allied partners in. That is an industrial expression of the kill web.

South Korea: Depth Through Industry, Dispersal and Manpower

South Korea is building depth along three lines at once.

The first is industrial. In its 13 October audit briefing to the National Assembly’s Defense Committee, Seoul’s arms agency DAPA requested ₩22.7 trillion for 2027, up 13.8 percent, with weapons procurement and production rising 19.4 percent, according to Financial News. DAPA also confirmed that a nuclear-powered submarine project team has been formally established.

The acquisition reforms matter as much as the money. Companies, rather than the services alone, would propose performance targets and schedules. Systems would be fielded early and upgraded continuously rather than held back for a complete design. The period for rapid demonstration projects would be cut from two years to one, specifically to field drones and satellites faster. In effect, Seoul is trying to move at the speed of change rather than the speed of a traditional requirements process.

The second line is operational. Speaking at the AUSA annual meeting in Washington, General Xavier Brunson, commander of US Forces Korea, said the two big annual exercises on the peninsula “focus on large command posts” and that the allies have “got to move away from that,” as reported by Korea JoongAng Daily. He called for training “across the entirety of the peninsula,” from Jeju to Gyeonggi, and drew directly on Ukraine, where drones make fixed positions vulnerable. “We won’t be moored in place,” he said.

Brunson also warned that North Korean troops fighting in Ukraine are feeding combat lessons into Pyongyang’s training and weapons development. That is a sobering point. The adversary is learning in combat while the alliance is still learning in exercises. Dispersal, mobility and resilient command are the answer, and they are as much a matter of mindset as of equipment.

The third line is people. At a National Assembly audit on 12 October, Korea’s Military Manpower Administration backed plans to reduce or abolish supplementary service exemptions for athletes, artists and others, and warned that the manpower pool will fall below 150,000 after 2040, according to Korea JoongAng Daily. Demography is a strategic constraint, and it is one more reason the Korean push toward autonomy and unmanned systems is not optional.

Korea is also creating geographic options. The containership Panstar Acro returned to Busan on 11 October after a 50-day round trip to Europe via the Northern Sea Route, as reported by The Maritime Executive. The voyage was not a commercial success, and it ran five days late. But President Lee Jae-myung has called for regular Arctic service by 2030, and the government aims for commercial viability by 2035. Whatever the economics, this is a nation building familiarity with an alternative sea route that bypasses the southern chokepoints.

Taiwan: Defending the Center, Distributing the Edge

Taiwan’s initiatives show resilience being built from the capital outward.

Taiwan’s defense ministry plans to nearly double the Military Police Command from 5,600 to 11,000 troops and to expand its role from policing and presidential security to combat as a motorized infantry force, according to the Taipei Times. Its mission would be to defend the Taipei metropolitan region and critical infrastructure against a decapitation strike.

The equipment list is essentially a counter-drone list: the US-made M-ACE vehicle-mounted counter-drone system, rifles with Smartshooter optics designed to engage drones at 400 meters, remote weapon stations carrying anti-tank missiles, and a presidential command vehicle disguised as a civilian car with jam-resistant satellite communications. This is a direct application of the lessons of Ukraine to the protection of a political center. The aim is simple: the government continues to function and command continues to flow.

At sea, the debate is about what kind of unmanned force Taiwan needs. At a TAITRA forum, Mira Resnick, a former deputy assistant secretary of state now with Saronic, noted that of Taiwan’s plan for more than 200,000 unmanned systems, only about 1,300 are boats, mostly single-use attack craft useful only once a war begins, as reported by Central News Agency. China, she argued, is wearing Taiwan down every day through gray-zone pressure that consumes fuel and, above all, scarce ship crews.

Her prescription was reusable, multi-mission autonomous surface vessels that return to port and go out again, autonomous enough that one operator can supervise many boats, and integrated with Taiwanese sensors, command and control, and local maintenance. That is the mesh-fleet argument: co-production and sustainment on the island, not simply arms sales. Taiwan’s economics ministry, meanwhile, approved 27 of 49 drone research projects worth NT$780 million, the largest going to AIDC for a GPS-independent heavy logistics drone, according to a separate Central News Agency report.

India: Sovereign Control of Connectivity

India offers a different but related example. The Observer Research Foundation has opened a debate on whether India should allow itself to depend on Starlink. One contribution argues that India’s gateway, geofencing and self-certification rules can discipline a foreign operator only after the fact, but “cannot guarantee that service will stay on when India needs it and off when it does not,” according to ORF. Another, by ORF’s vice-president, concludes that Starlink should go the Huawei way in India.

Whatever one thinks of that conclusion, the question is the right one. Connectivity is now a warfighting capability. Who holds the off switch is a question of sovereignty, and India is asking it out loud.

Australia: A Cautionary Note

Not every allied decision runs in the same direction. BAE Systems Australia is selling the Williamstown shipyard in Victoria, which dates to 1858 and built all ten ANZAC-class frigates as well as the superstructures of the two landing helicopter docks. The buyer is EMKC3, a property fund part-owned by Hong Kong-based EMKC Group, as reported by Australian Defence Magazine. The site was listed in 2024 at up to A$200 million and is reportedly being sold for considerably less. Victorian law requires it to stay in marine-engineering use, and Treasury declined to say whether the Foreign Investment Review Board is involved.

Set beside Japan’s subsidized hull-block plant and Kure’s unmanned-systems park, the contrast is sharp. Tokyo is treating shipbuilding capacity as an economic-security asset. Here, a major naval shipbuilding site is being handled as a property transaction. For a nation investing heavily in maritime power under AUKUS and its surface fleet plans, the location and ownership of shipbuilding and repair capacity deserves the same strategic attention as the ships themselves.

What This Means for the Alliance

Three conclusions emerge from a single week of reporting.

First, resilience is being priced in cash and law, not only in steel. Japan’s energy bills, its economic-security certification of a shipyard and India’s satellite debate are all cases of governments using funds, regulations and licensing to reduce dependence. The contest is being shaped by treasuries and regulators before it is fought by navies.

Second, the operational lessons of Ukraine are now driving allied force design in the Indo-Pacific. Dispersal in Korea, counter-drone defense of Taipei and the push for reusable autonomous boats all reflect the same understanding: fixed and concentrated forces are targets, and survivability comes from distribution, mobility and the ability to regenerate.

Third, industrial depth is becoming the foundation of strategic depth. The ability to build, repair and upgrade hulls and unmanned systems near the fight, ideally with allied partners, is what turns a force into a sustainable one. Kure’s explicit invitation to international co-developers is a model the United States should engage with directly.

For Washington, the implication is that the allies are not waiting. They are building their own depth in ways that can either be integrated into a broader allied kill web or left as separate national efforts. The opportunity is to connect them through co-production, shared sustainment, interoperable autonomy and a common understanding of where the vulnerabilities lie. The risk is that the United States continues to think in terms of platforms and arms sales while its allies are already thinking in terms of resilience.

The headlines will continue to focus on the visible.

The decisions that will matter most are being made beneath them.
