“At this critical moment, the Joint Force is contending with an acquisition process and defense industrial base that are not optimized for protracted conflict. The U.S. does not have the throughput, responsiveness, or agility needed to deter our adversaries.” — Chairman of the Joint Chiefs of Staff, General Dan Caine, U.S. Air Force

General Caine’s assessment is a warning order for the U.S. Navy. Supply chain resilience underpins every aspect of naval power. From modernizing the fleet to sustaining existing platforms and from routine peacetime operations to contested logistics during a protracted conflict, the strength and adaptability of the Navy’s supply chains will determine whether the service can carry out its mission when called on. The supply chains supporting today’s military are complex and interdependent. Modern naval platforms are marvels of engineering—and nightmares of logistics. A single destroyer relies on thousands of suppliers across multiple tiers, spanning continents and industries. A critical microchip might be fabricated in Taiwan, while specialized steel alloys come from a handful of domestic foundries and precision-machined components come from small shops in the industrial heartland. When any link in this chain breaks, readiness is interrupted. Honest assessment is the first step toward forging a resilient supply chain. The Navy must evaluate the state of its logistical lines, qualify new suppliers to expand and optimize industrial capacity, and plan for alternative sources in case combat disrupts normal channels. This is existential work for a Navy that seeks to deter great powers and, if necessary, fight them and win.

Measuring Resilience

The old management maxim holds true: You cannot improve what you do not measure. Without data on supply chain performance, it is impossible to determine whether logistical networks are fragile or resilient. The Navy needs to develop a system to measure that performance so it can answer fundamental questions: Are critical suppliers financially stable? Do they maintain adequate surge capacity? Can they source raw materials from multiple vendors? These questions demand answers grounded in data, not assumptions. A comprehensive measurement framework must accomplish several objectives. First, it must visualize multitier supply chains. Prime contractors may appear healthy, but what about their lower tier suppliers—the specialized manufacturers producing components no one else can? A weakness three tiers down can cascade to disrupt the production of a billion dollar warship. Second, measurement enables accountability. On-time delivery rates, quality metrics, and price trends reveal which suppliers are performing and which are struggling. By analyzing these metrics, program managers could identify suppliers who need support before small problems become program-killing failures. Early intervention—whether through additional contracts, technical assistance, or capital investment—could stabilize a wobbling supply base before it collapses. Third, resilience metrics could derisk naval modernization, sustainment, and combat readiness. Consider the Columbia-class ballistic-missile submarine program, for which schedule adherence is nonnegotiable. Real-time supply chain visibility would allow program managers to identify potential delays months in advance, enabling corrective action before the critical path is affected. For sustainment, resilience data could reveal which aging platforms face parts-obsolescence risks, informing decisions about service life extensions versus early retirement. For combat readiness, metrics could identify potential points of failure that could cripple fleets. The technology to achieve this visibility exists.

can map supply chains in detail. The challenge is organizational. To systematically measure and share resilience requires breaking down bureaucratic silos, incentivizing information sharing, and investing in the kind of mundane back-office systems that make modern warfare possible.

Enhancing Resilience Through Supplier Diversification

Measurement reveals vulnerabilities; action addresses them. The new tool the Navy most needs for building resilience is systematic qualification of new suppliers to expand industrial capacity and eliminate dangerous dependencies. The industrial landscape is riddled with single-source and sole-source suppliers—companies that are either the only qualified vendor or the only vendor, period, for critical components. This concentration risks catastrophe. A fire at one facility, a labor dispute, a bankruptcy, or sabotage could halt production across entire programs. The pandemic offered a preview of this fragility when semiconductor shortages cascaded through the economy, delaying everything from automobiles to weapon systems. Qualifying alternative suppliers is neither quick nor cheap. The Navy’s rigorous quality standards exist for good reason—lives depend on equipment performing flawlessly under extreme conditions.

Qualifying a new supplier for a complex component might require months of testing, facility audits, and process validation. But this investment ensures resilience, which is priceless. A supply base with multiple qualified vendors for critical items can absorb disruptions. Reliable economic incentives are crucial to increase the supplier base. Small and medium manufacturers will not invest in new equipment and workforce training on the possibility of occasional orders. They need the certainty of long-term contracts and guaranteed minimum volumes. The Department of Defense has tools to provide that certainty, from multiyear procurement authorities to economic order quantity contracting. Used strategically, these tools can stimulate investment in critical capabilities while distributing risk across a broader industrial base. Foreign partners also have a role to play. Many components can be sourced from allied nations with advanced manufacturing capabilities. Reciprocal qualification agreements, such as those envisioned under AUKUS, can create multinational supply networks resistant to disruptions in a single nation. A critical sensor unavailable from U.S. suppliers might be manufactured by British or Australian firms, while U.S. industrial capacity supports their programs in return.

Rapid Resilience for Contested Logistics

During a major conflict, such as a Taiwan contingency, the Navy’s supply chains would face stresses they have not experienced since World War II. Planning, measurement, and supplier qualification in peacetime aim to maintain operational capability during sustained combat. Consider the logistics challenge. Taiwan is a critical node in global supply chains. It produces the advanced semiconductors that permeate modern weapon systems. A conflict in the Taiwan Strait would increase demand for these components while potentially cutting off their primary source. Ships damaged in combat would require repair parts fabricated from materials that may no longer be accessible through normal channels. Prime contractors such as Lockheed Martin and transportation providers such as Maersk operate sophisticated global networks optimized for peacetime efficiency. War would shatter those optimizations. Routes would become contested, ports close, and suppliers in combat zones cease operations. The logistics enterprise must rapidly pivot from just-in-time delivery to whatever-it-takes survival mode.** The Defense Logistics Agency and Naval Supply Systems Command would bear enormous responsibility in such a scenario. Their peacetime mission of cost-effective, efficient supply chain management would give way to the wartime imperative to maintain the flow of critical matériel under fire. Stockpiles would be positioned forward in protected locations, while alternative transportation routes are activated. Surge production would begin even as normal production is disrupted.
