How to Become a Defence Subcontractor in Europe

Start with the programme, not the notice

Most suppliers try to enter European defence by watching tender portals. That is the least productive starting point, for two structural reasons.

First, a large and growing share of defence contracts is never advertised. Article 346 TFEU lets a Member State protect essential security interests, and Directive 2009/81/EC permits negotiated procedures without publication in defined cases. Belgium's counter-UAS framework agreement was advertised in March 2026 under Article 346(1)(b) TFEU with no estimated value at all — while the underlying capability line, €368,880,600, sits in a published capability portfolio.

Second, when a notice appears the decisions that matter are already taken. Our monitoring flagged Belgium's next 72-month soldier equipment framework on 3 June 2026, when reference MRMP-S/AT No 26ST640 was published with a deadline of 7 July 2026 [7] — four weeks on a contract that closes the market for six years. Identify the programme upstream, decide whether you bid as a prime or position as a subcontractor, and register before the notice.

Article 21: the rule that turns a prime's supply chain into a competition

The most under-used provision in European defence procurement is Article 21 of Directive 2009/81/EC, headed « Subcontracting ».

Article 21(4) provides that Member States may allow a contracting authority to « ask or be required to ask the successful tenderer to subcontract to third parties a share of the contract ». That share must be expressed as a range with a minimum and a maximum, and — the operative sentence — « The maximum percentage may not exceed 30 % of the value of the contract. » The winner must then award those subcontracts « in accordance with the provisions of Title III » [1].

Article 21(3) is the companion: the authority may oblige the winner to apply Title III to all or certain subcontracts it intends to award. Title III — Articles 50 to 54, covering scope, principles, thresholds and advertising, qualitative selection of subcontractors and the rules to be applied — converts the prime's own procurement into a regulated, advertised competition [1].

Two consequences. Where the clause is used, subcontracts are published and open, and a firm that has never held a defence contract can bid. And Article 21(5) limits the prime in the other direction: a subcontractor may be rejected only on criteria applied to select tenderers for the main contract, and the rejection must be justified in writing.

Entry points currently open across categories

Note the pattern: the two largest published values in this table are an EU agency common procurement and a works contract. Neither is a national defence equipment tender, and both are fully open.

The thresholds, exemptions and EU incentives that shape access

Four legal parameters determine what you see and what you are paid to do.

Thresholds. From 1 January 2026, Directive 2009/81/EC applies at or above EUR 432,000 for supplies and services and EUR 5,404,000 for works, under Commission Delegated Regulation (EU) 2025/2487 of 2 December 2025. Both fell from EUR 443,000 and EUR 5,538,000, because the thresholds track the special drawing right under the WTO Government Procurement Agreement [2].

Article 346 TFEU. A Member State may exclude a procurement to protect essential security interests. The contract still exists and the programme is still budgeted; only the advertisement disappears.

SAFE. Article 19 of Council Regulation (EU) 2025/1106 states that « Procurements involving at least one Member State receiving financial assistance under the SAFE instrument shall be deemed to satisfy the condition of urgency resulting from a crisis for the purposes of Article 28(1), point (c), of Directive 2009/81/EC » — the negotiated procedure without publication, applied by operation of law. Article 6 sets the ceiling at EUR 150,000,000,000 in loans [3]. As SAFE-financed procurement grows, the share of European defence spending visible in notices will fall.

EDIP. Regulation (EU) 2025/2643 raises the Union contribution to up to 50 % of eligible costs « where the majority of beneficiaries are SMEs or mid-caps », against a base rate of 35 %, and rewards actions where « more than 20 % of the total value of the end product is made by suppliers established in at least one Member State other than the Member State in which the prime contractor is established » [4]. A prime assembling a consortium therefore has a measurable reason to include cross-border SMEs.

Registration: five platforms and two agencies cover most of the market

The practical work of becoming a supplier reduces to a manageable list: onboarding across the major European primes is concentrated on a handful of platforms.

No European prime publishes a minimum turnover requirement. The published barriers are certifications and, in the United Kingdom, shared sector accreditation through JOSCAR, completed once and consulted by multiple buyers [8]. The NSPA route is the most under-used: its ePortal hosts Future Business Opportunities — « advanced notification of future large procurement opportunities » — alongside notices of intent and requests for proposals [5]. France's state platform PLACE [12] and prime portals such as Naval Group's [13] complete the picture.

Several states also publish preliminary market consultations, the most actionable single signal in the system. Poland's Armament Agency publishes its wstępne konsultacje rynkowe on its public information bulletin, each with a subject, an application deadline and consultation dates [9]. Applying costs nothing and puts a supplier in the room while the specification is still being written.

How Dfensio tracks defence procurement programmes across Europe

Dfensio reads the documents European states must publish before they can commit money: programming laws and their annexes, capability investment portfolios, budget performance annexes, council-of-ministers decisions, preliminary market consultations, EU and NATO agency award streams, and the supplier pages of the primes. Every programme becomes a record carrying the official value where one exists, the first commitment year, the contracting scope the state itself declared, and the source with its publication date.

For subcontracting we track three things a tender feed does not carry: whether a notice invokes the Article 21 requirement, and therefore whether the prime's own procurement will be advertised; the expiry date of existing frameworks, the only moment a closed market reopens; and the qualification requirements each prime and agency actually publishes.

All of it is built from official, published sources. Dfensio does not handle classified, restricted or non-public information. Client briefings are confidential, and we do not disclose which programmes or which primes a client is pursuing.

A practical checklist, and next steps

1. Map your capability against the named capability lines of two or three states, and note each first commitment year.
2. Register on the platforms covering the primes in your domain — roughly five accounts plus a few proprietary forms.
3. Obtain the certifications those primes publish, and an NCAGE code with NSPA ePortal registration for the NATO route [6].
4. Apply for preliminary market consultations in your category: open, free and early.
5. Identify the frameworks expiring within twenty-four months. Those are the competitions you can realistically win.
6. When a prime wins a large contract, approach it within sixty days: that is when the first tier-one subcontracts are placed.
