Deterrence by Denial Starts With a Strong Defense Industrial Base

Why Indo-Pacific deterrence depends on production capacity, supply chain resilience, and the ability to manufacture critical defense systems at scale.

The United States is refining its strategy for preserving stability in the Indo-Pacific. In recent remarks at the Stratbase Institute in Manila, Under Secretary of War for Policy Elbridge Colby said the United States intends to maintain a posture of deterrence by denial along the first island chain. Quoting Secretary of War Pete Hegseth’s remarks at the 2026 Shangri La Dialogue, Colby described a denial defense in the Western Pacific that makes “aggression infeasible, escalation unattractive, and war deemed irrational.”

That is the right strategic objective, but policy statements, defense agreements, and budget authorizations will not create deterrence on their own. The strategy must be supported by a defense industrial base that can manufacture, deliver, maintain, and replenish critical military systems at the required speed and scale.

Experience inside factories reinforces one consistent lesson: a plan is only as credible as the ability to execute it. Execution requires production lines with reliable access to raw materials, qualified suppliers, skilled workers, disciplined manufacturing processes, and enough production capacity to meet demand from the United States and its allies. The credibility of deterrence by denial will ultimately be decided on the factory floor.

Deterrence Requires Industrial Capacity

Deterrence by denial is intended to convince an adversary that it cannot accomplish its military objectives at an acceptable cost. Across the Indo-Pacific, that requires credible capabilities involving missiles, air and missile defense, autonomous systems, aircraft, ships, sensors, communications equipment, and electronic warfare. Developing those technologies is only the beginning because they must also be manufactured in sufficient quantities, delivered according to dependable production schedules, maintained throughout their service lives, and replenished quickly if inventories are depleted.

The distances across the Indo-Pacific make this challenge even more consequential. Forces may need to operate from dispersed locations while relying on vulnerable logistics routes, which means even the most advanced system loses value if it cannot be repaired, resupplied, or replaced when needed. A successful prototype may prove that a technology works, but it does not demonstrate that the industrial base can produce and sustain it reliably at scale.

Defense manufacturers can face constraints involving specialized tooling, facility space, skilled labor, castings and forgings, microelectronics, propulsion systems, critical minerals, and other raw materials. A delay or quality problem involving one supplier deep in the network can interrupt production lines and delay an entire weapon system. Production capacity is determined by the weakest constraint in that network rather than its strongest participant.

The Department’s fiscal year 2027 defense budget request identifies more than $100 billion in defense industrial base investments, including funding intended to address critical minerals, strategic materials, microelectronics, batteries, castings and forgings, and maritime manufacturing. These investments are necessary, but funding alone will not create capacity. Defense programs must evaluate requirements early, identify constraints across the supply chain, and direct capital toward the problems most likely to restrict production.

Better Factory Performance Can Unlock Capacity

When demand rises, the first reaction is often to discuss a new factory, another production line, or more equipment. Those investments may be necessary, but many manufacturers can unlock meaningful production capacity within existing facilities by improving production efficiency and removing operational barriers.

That effort begins with understanding how people, raw materials, information, and products move through the factory. Leaders need to identify excessive work in process, equipment outages, labor shortages, inconsistent instructions, quality escapes, poor material flow, and manufacturing processes that cannot support the required rate. They must also understand how greater customer demand will affect equipment utilization, staffing, working capital, and quality assurance.

Improvement efforts should balance production lines around actual demand, increase equipment utilization, reduce downtime, shorten cycle times, strengthen quality assurance, and create dependable production schedules. Better material flow and inventory management can also increase throughput without immediately requiring major capital spending. When these efforts are sustained, they improve supplier performance, delivery reliability, and military readiness.

Artificial intelligence can support this work when it addresses a clearly defined problem and relies on accurate data. It can help analyze equipment performance, detect quality trends, improve production planning, forecast material requirements, and identify supply chain risks. Predictive maintenance can also help prevent equipment failures and reduce downtime, but technology cannot replace disciplined operations. It creates the most value when applied to manufacturing processes that leaders already understand, measure, and control.

Supply Chain Visibility Must Lead to Action

Prime contractors cannot manage production risk effectively if their visibility ends with immediate suppliers. The Department estimates that more than 200,000 suppliers help produce advanced weapon systems and noncombat goods, yet it still has limited insight into the origins of many parts and raw materials.

A Government Accountability Office assessment found that the primary federal procurement database provides little visibility into where goods purchased by the Department are manufactured or whether materials and parts come from domestic or foreign suppliers. GAO also found that other visibility efforts remained limited in scope and provided little insight into most suppliers, especially those providing parts and raw materials.

Manufacturers, prime contractors, and defense organizations need to know which components depend on a single source, where significant foreign dependencies exist, which materials have unusually long lead times, and whether smaller suppliers can support higher production rates. Supply chain mapping should guide supplier diversification, alternate sourcing, strategic inventory, domestic production, supplier development, and capital investment rather than become an administrative exercise that produces little action.

Colby’s call for “partnership, not dependency” should also apply to allied industrial cooperation. Indo-Pacific allies can contribute through component manufacturing, shipbuilding, aircraft maintenance, munitions production, logistics, and sustainment. With clear requirements, compatible standards, secure supply chains, and defined responsibilities, cooperation can expand collective production capacity, distribute risk, and place maintenance capabilities closer to potential operating areas.

Innovation and Surge Capacity Must Be Built Before a Crisis

The United States remains a global leader in defense innovation, particularly in artificial intelligence, autonomous systems, advanced sensors, electronic warfare, and next-generation weapons. However, demonstrating a promising technology does not automatically create a deployable military capability.

Companies moving from prototype development into production must establish repeatable manufacturing processes, qualified suppliers, production controls, workforce plans, inspection standards, and effective quality management systems. Designs must also be affordable, reliable, maintainable, and practical to manufacture at the required rate. Bringing engineers, manufacturing leaders, procurement teams, quality professionals, and suppliers together early can reduce risk and accelerate the transition into repeatable production.

The same discipline applies to surge production. Manufacturers cannot wait for a crisis to determine whether they have enough tooling, floor space, qualified workers, capable suppliers, approved raw materials, and proven manufacturing processes. Defense manufacturers and government program offices should understand their maximum sustainable rates, the time needed to activate additional production capacity, and the investments required to remove critical constraints.

Overtime and additional shifts may raise output temporarily, but they do not create sustainable capacity. If equipment is already stretched, suppliers are constrained, or workers are exhausted, additional pressure will eventually create more downtime, quality problems, and missed deliveries. Real surge production requires capital investment, supplier development, workforce preparation, and careful planning before demand exceeds what the production system can support.

Deterrence Depends on Industrial Execution

The success of deterrence by denial will ultimately depend on what the United States and its allies can deliver, maintain, and replenish, not simply what they intend to develop, fund, or purchase.

A credible Indo-Pacific posture requires the defense industrial base to increase production output, improve production efficiency, secure reliable access to raw materials, reduce downtime, and strengthen supplier performance. Factories must also develop enough capacity to replenish critical systems during periods of sustained or rapidly increasing demand.

Policy defines the strategic objective, budgets provide resources, and artificial intelligence creates new opportunities for improvement. Factories, suppliers, workers, and manufacturing processes determine whether those resources become operational military capability.

If the United States wants to make aggression infeasible, it must build a defense industrial base with the strength, depth, and resilience to withstand disruption, sustain production, and deliver when the nation needs it most.
