Sovereign Supply Chains: How Defence Procurement Is Rebalancing Toward Resilience

In aerospace and defence, global efficiency can no longer come at the expense of strategic vulnerability.

Tariffs, export controls and geopolitical risk have made industrial-base sovereignty a board-level priority. The demand surge only sharpens it: indirect procurement spend across European aerospace and defence primes has grown 43% year on year, and every new supplier is a new sovereignty question.

Yet sovereignty is easy to claim and hard to evidence. For procurement, the challenge is not slogans about resilience; it is proving country of origin, securing critical categories, and doing both without stalling delivery.

This article examines why sovereignty has moved to the centre of aerospace and defence procurement, where the risk concentrates in indirect spend, and how leading teams rebalance toward resilience without a wholesale retreat from global sourcing.

Sovereignty is a delivery question, not a slogan

The instinct under pressure is to talk about resilience in the abstract. The operational reality is narrower: can you prove where a part came from, and can you get it if a border closes?

That reframes sovereignty as a procurement discipline. It is about evidenced origin, dual-sourcing of critical categories, and trusted-ally partnerships, not a blanket preference for local at any cost.

The buyers who treat it as a delivery question, rather than a policy statement, are the ones who stay supplied when disruption hits.

The risk hides in indirect spend

Direct components are scrutinised for origin. Indirect spend, the chemicals, tooling, MRO consumables, IT and services behind every airframe, rarely is, and it is where sovereignty exposure quietly accumulates.

It compounds because indirect spend is poorly seen: only 50 to 60% of it is clearly visible in most aerospace and defence organisations. You cannot assure the origin of what you cannot see.

A late or blocked indirect item stops a build as surely as a missing structural part. Sovereignty that stops at the direct bill of materials is sovereignty with a hole in it.

Near-shoring is a rebalancing, not a retreat

The shift is real: across industrials, nearly half of A&D executives expect to reshore or near-shore most production by 2030. But the smart version is selective, not total.

Leading teams dual-source critical categories, build regional ecosystems, and concentrate near-shoring where the sovereignty risk is highest, while keeping global sourcing where it is safe and efficient.

The honest concession: near-shoring can cost more per unit, and not every category justifies it. The discipline is knowing which ones do.

Consolidation is how you get sovereignty and control together

Fragmented indirect buying makes origin impossible to track and leverage impossible to build. Consolidating the supplier base into one governed, vetted route does the opposite.

Fewer, vetted suppliers behind one workflow means origin is evidenced by default, and the diversity that matters, controlled access to many suppliers, is retained without the management overhead.

Supplier diversity up, management overhead down, origin evidenced throughout. That is controlled diversity, not dependence.
