The Impact of Supply Chain Disruptions on Defense Electronics Manufacturing

In 2024, supply chain disruptions in Aerospace and Defense (A&D) rose 35% YOY, from 9,188 to 12,356 events. Lead times stretched from weeks to months for defense-grade parts, tariffs and shortages drove costs up and profits down, and all while complex, multi-tiered, globalized (yet often single-sourced) supply chains built for cost proved unable to mitigate and respond. What followed were wide-scale delays, eroded profit margins, compromised operational readiness, and heightened project risks. A 2025 Defense Business Board report found that global semiconductor shortages have slowed advanced weapons productions and underscored US dependence on foreign microchip suppliers, a vulnerability that will become a strategic liability as defense demand accelerates.

KPMG has found that the global A&D sector faces rapid growth; Airbus and Boeing predict more than 40,000 new commercial jets will be manufactured over the next 20 years, and global defense spending rose by nearly 10 percent in 2024, its fastest growth rate in nearly four decades. Operational readiness, mission availability, and trusted-supplier requirements make defense electronics uniquely sensitive to supply chain shocks that could impede this trajectory. In this article, we bring light to the challenges, unravel the implications, and provide practical insights and actionable takeaways for leaders looking to gain real competitive edge through the chaos.

The New Landscape is Volatility in Component Supply

The new baseline for defense electronics is systemic turbulence. It’s showing up in extended lead times, lack of inventory when it is needed, and cost spikes for essential components. This means leadership needs to plan for the long term.

At low volumes, defense manufacturers can still procure from franchise distributors when available, including MIL-PRF rated components. At higher volumes, there has only been marginal relief in component lead times for defense-grade parts. Certain high-performance components required at volume, such as processors or HBM, can carry lead times on the order of months. In addition, some high-reliability passives like MIL-PRF resistors and capacitors, remain at zero inventory with franchise distributors despite expected growth in demand for these components.

Part of the challenge is in procurement of MIL-PRF or space-grade commodity parts, where there is simply not enough domestic capacity to satisfy new US and NATO procurement commitments. In designs where non-MIL-PRF parts are acceptable, geopolitical risk arises due to the fact that 80% of the world's semiconductors are manufactured in Asia, making disruptions in that region a significant risk. There has also been notable growth in demand for these parts due to competition with commercial efforts such as data center buildouts, suggesting the A&D supply chain will remain under significant pressure.

Key Takeaway 1: Shift from Reactive Sourcing to Predictive Allocation

Defense OEM primes and ODMs must anticipate and plan for this turbulence by:

• Removing barriers to multi-sourcing
• Executing advanced buys to secure allocation
• Securing allocation commitments directly from component manufacturers

This shift necessitates continuously monitoring lead-time and cost trends to execute strategic inventory purchases, balancing financial and operational risks.

Eliminating Single-Source Risk

Single‑source electronics and subassemblies amplify disruption risk in defense.

The root of this vulnerability lies in industry consolidation: over the last three decades, the number of qualified suppliers in major weapons system categories has substantially declined: the Department of War notes that tactical missile suppliers have decreased from 13 to three, fixed-wing aircraft suppliers from eight to three, and today, 90% of missiles originate from just three sources. This constrained environment inherently drives more single-sourcing in specialized defense electronics.

For critical components, such as PCB fabricators, FPGA vendors, and specialist analog/mixed-signal suppliers that are the "only game in town" for certain mil-grade or space-grade parts, this concentration has severe implications for lifecycle risk. High barriers to qualification (including ITAR, MIL-PRF, and counterfeit avoidance) make rapid multi-sourcing slow and prohibitively costly. That slow pace is exactly what turns a simple design constraint into a long-term risk.

Key Takeaway 2: Mandate Design-for-Multi-Sourcing

Design teams now have a duty to avoid single-source dependencies through a formal Design-for-Multi-Sourcing mandate. This approach aligns with the DoD’s Modular Open Systems Approach (MOSA) and Sensor Open Systems Architecture (SOSA), which emphasize open standards and modular architectures enabling components from multiple qualified vendors. A proactive mandate reduces redesign cycles from unexpected component end-of-life (EOL), avoiding non-recurring engineering (NRE) costs.

Can We Align Geopolitics, Security, and Compliance?

During the Biden administration, the Quadrennial Supply Chain Review concluded that policy must be used to reshape defense supply chains. The US administration’s trade strategy emphasizes domestic production by using tariffs and incentives to bring microelectronics, substrates, and critical materials back to North America. There is also discussion of building allied capacity for these inputs and reducing exposure to chokepoints held by foreign adversaries.

Meanwhile, the threat landscape around cyber infiltration is intensifying. The digital supply chain is now a primary vector for espionage and IP theft, with adversaries exploiting Tier-2 and Tier-3 suppliers to insert malicious functionality or access Controlled Unclassified Information (CUI). In response, the DoW is implementing the Cybersecurity Maturity Model Certification (CMMC) 2.0 framework, a mandatory flow-down requirement that forces every supplier to meet defined cybersecurity standards.

Together, these pressures are nudging the sector away from cost-centric models that no longer match today’s risk profile. As the Deloitte 2026 Aerospace and Defense Industry Outlook report points out, the longstanding preference for low-cost, offshore suppliers has left defense programs dependent on fragile global supply networks designed for peacetime rather than contested environments. That mindset is shifting: investment in supply-chain resilience and security is now viewed not as overhead, but as mission-critical insurance to protect operational readiness and preserve technological advantage.

Key Takeaway 3: Embed Geopolitical Risk into Compliance and Vetting

Leaders must move beyond periodic supplier audits and treat geopolitical exposure as a core compliance function. This means continuous traceability, deeper sub-tier vetting, and verification of cybersecurity maturity (including CMMC obligations). At the same time, sourcing strategies should align with government friendshoring incentives that support domestic PCB, substrate, and advanced packaging capacity. Leveraging these programs strengthens supply security while creating opportunities for long-term capital investment and growth.

From Resilience as Cost to Resilience as Advantage

The next supply chain shock is not a question of if, but when. What will differentiate defense electronics leaders is not the ability to react fastest after disruption hits, but the discipline to design resilience into systems, suppliers, and decisions before the shock arrives.

In an era defined by geopolitical fracture, constrained capacity, and rising compliance thresholds, supply chains are no longer a back‑office function but a strategic capability that directly determines program survivability, schedule integrity, and mission readiness. Organizations that continue to treat sourcing as a cost‑optimization exercise will absorb the full force of future volatility. Those that treat it as a core element of national security strategy will shape outcomes instead of scrambling to recover from them.

The leaders who emerge stronger will be those who:

• Embed supply risk into design, not just procurement
• Treat allocation and supplier access as strategic assets
• Invest early in trusted ecosystems aligned with national and allied priorities

Defense electronics manufacturing is entering a period where resilience, transparency, and adaptability define competitiveness. By acting now—before the next disruption tests the system—leaders can turn supply chain uncertainty into a durable strategic advantage.
