Highlights

• The defense industry is shifting from efficiency-focused just-in-time models to resilience-based supply chains, as vertical integration proves too slow and capital-intensive to address upstream constraints in critical minerals and rare earths.
• Current ERP and supply chain systems fail to address element-level constraints, midstream chokepoints, and deep-tier opacity, while DFARS 2027 will require full traceability from mining through production.
• Competitive advantage will belong to organizations that can orchestrate supply chain on demand through pre-qualified networks, deep-tier visibility, compliance-ready provenance, and dynamic capacity reservation.

Is efficiency as the organizing principle of global industry coming to an end? The defense industrial base is already answering that question. It is entering a new operating reality—one where assurance, not optimization, defines success. In this environment, advantage will accrue to those who can see deeper, adapt faster, and externalize quality and secure capability on demand. The future will not be won by those who run the leanest systems—but by those who can continuously operate, pivot, and deliver under pressure.

For decades, supply chains were optimized for cost, speed, and capital efficiency. “Just-in-time” wasn’t just a method—it was a doctrine. That doctrine is now failing under the weight of tariffs, export controls, geopolitical fragmentation, and defense procurement rules that increasingly treat upstream inputs—especially critical minerals and rare-earth components—as strategic infrastructure rather than commodities.

The shift is measurable. Research (opens in a new tab) from McKinsey & Company shows companies rebuilding buffers and diversifying suppliers, while still lacking deep visibility—95% can see tier-one risk, but only 42% beyond it. Meanwhile, the Wharton School confirms (opens in a new tab) firms are actively rethinking their dependence on just-in-time models.

This is not a temporary correction. It is a structural reset.

The False Promise of Vertical Integration

Faced with instability, many primes and OEMs have moved toward vertical integration—attempting to “own” their supply chains again. But this strategy collides with physical reality.

Rare Earth Exchanges™ has quoted a handful of prominent sources that estimate that new mines take over 16 years from discovery to production (opens in a new tab). Rare earth separation, alloying, and magnet manufacturing require specialized ecosystems that cannot be rapidly replicated. The result: ownership is slow, capital-intensive, and often strategically misaligned.

Even policy now reflects this constraint. A 2026 directive from The White House (opens in a new tab) explicitly warns that mining alone does not confer security if processing remains foreign-dependent.

Vertical integration is not a solution. It is, at best, a partial hedge.

What the Defense Industry Actually Runs Today

Modern defense primes operate layered, fragmented digital architectures:

• ERP backbone (finance, procurement, manufacturing)
• Planning and orchestration tools
• Supplier portals and networks
• Risk and “illumination” platforms

This stack is powerful—but deeply constrained.

Take Lockheed Martin: internal materials show back in 2019 14 ERP instances and 18+ million lines of custom code (opens in a new tab).

Northrop Grumman started consolidating disparate ERP systems into SAP S/4HANA.

L3Harris Technologies is pursuing a “single ERP” vision (opens in a new tab)—still years in execution.

Boeing is executing a multi-year shift to SAP S/4HANA to unify its fragmented ERP landscape and modernize supply chain and manufacturing operations. Decades of acquisitions and program-specific needs have left a patchwork of legacy systems (including Baan/Infor and specialized tools), much of which still persists across business units. Classified programs remain on separate, secure ERP environments. While S/4HANA promises automation, digital twin integration, and improved parts visibility, the reality is clear: Boeing—and the broader defense sector—is not replacing legacy systems overnight, but layering and integrating them over time, resulting in prolonged coexistence of multiple ERP environments.

ERP systems manage transactions. They do not manage reality.

The Real Constraint: Rare Earths and Critical Minerals

The defense supply chain does not break at the ERP layer. It breaks upstream.

Rare earth permanent magnets—especially NdFeB—are indispensable to modern defense systems. The U.S. Government Accountability Office (opens in a new tab) identifies them as critical for radar, guidance systems, and precision weapons due to their strength and thermal stability.

But the real issue is structural:

• Supply chains span multiple opaque tiers
• Value—and risk—increase downstream
• Substitution is extremely difficult

The most critical inputs—neodymium, praseodymium, dysprosium, and terbium—are highly concentrated and processed predominantly in China.

By2024:

• ~60% of mined supply
• ~90%+ of processing
• ~94% of magnet production

This is not concentration. It is a strategic dependency.

Why Today’s Systems Fail

The failure is not technological—it is conceptual.

ERP and supply chain systems are built around:

• Parts
• Suppliers
• Purchase orders

But resilience in critical minerals is governed by:

• Element-level constraints (Nd, Dy, Tb availability)
• Midstream chokepoints (separation, alloying)
• Deep-tier opacity
• Regulatory traceability (DFARS 2027)

The result is a systemic mismatch.

A program can be:

• Fully compliant at tier one
• Fully visible in ERP
• Fully optimized in planning

…and still fail due to a constraint three tiers upstream.

The Software Market: Powerful—and Insufficient

The defense supply chain software ecosystem (opens in a new tab) is dominated by strong but incomplete solutions:

• ERP: SAP, Oracle
• Planning: Kinaxis, Blue Yonder, o9 Solutions
• Risk: Interos, Exiger, Palantir Technologies
• Traceability: Circulor (opens in a new tab) and other emerging solutions.

Each solves a piece of the problem:

• ERP → execution
• Planning → optimization
• Risk → visibility
• Traceability → provenance

But none integrates all four into a coherent operational system for resilience. And what about the dynamic tracking of risk, real-time, real-world geopolitical and micro environmental conditions that can change assumptions overnight?

The Coming Shock: DFARS 2027

Regulation is about to expose this gap.

By 2027, DFARS rules will require full supply chain traceability for magnets—from mining through final production.  This transforms provenance from a reporting function into a gating requirement.

Companies that cannot prove upstream compliance will not compete.

The Only Viable Path: Orchestration, Not Ownership

The defense sector faces a hard truth:

• Just-in-time is too fragile and now antiquated as we enter the Great Powers Era 2.0
• Vertical integration is too slow
• ERP systems are too narrow

And firms are not equipped to move nimbly at the necessary speed.

What emerges is a third model: Supply Chain on Demand

Rare Earth Exchanges envisions a model that reframes the problem entirely.

Instead of owning supply, it orchestrates it:

• Pre-qualified supplier networks
• Deep-tier visibility (tier-N mapping)
• Capacity reservation and optionality
• Compliance-ready provenance
• Dynamic buffers and routing

It sits above existing ERP systems, not replacing them—but making them effective in a world they were never designed for.

The aim of our defense contractors must be for a supply chain on demand as part of a quest to transform fragmented, opaque supply chains into reservable, traceable, compliance-ready networks.

Final Word: The New Competitive Advantage

The defense industry does not suffer from a shortage of software; it suffers from a misalignment between digital systems and geopolitical reality. In this emerging era, competitive advantage will no longer be defined solely by cost leadership, speed of delivery, vertical integration, or even traditional notions of quality.

These attributes, while necessary, are no longer sufficient in a world shaped by export controls, supply concentration, and strategic resource constraints. The defining capability will be far more fundamental: the ability to ensure continuity under constraint. Organizations that can secure supply, prove provenance, adapt in real time, and operate through disruption will set the new standard.

This is not an incremental improvement—it is a structural shift in how defense supply chains must be designed, governed, and executed.
