MEYER manufactures Type IV PET-lined composite pressure vessels and HDRX-series high-pressure regulators in Denmark, EU. For defence UAV programmes — hydrogen-fuel-cell propulsion, swarm pressurant systems, special-operations breathing apparatus — our hardware is the structurally advantaged answer to a question European primes have been asking since 2024: “can we source aerospace-grade composite cylinders without US export-control exposure?”
The single positioning line: ITAR-free, EU-origin, aerospace-grade Type IV. No re-export licence required. Single Danish engineer-of-record on every qualification dossier. Traceable batch serials. Compatible with NATO codification.
Why MEYER for defence UAV
ITAR-free supply chain
Danish manufacturing means cylinders are not subject to US ITAR controls. Component-level export from Denmark requires only standard EU dual-use clearance (Erhvervsstyrelsen track) — no US re-export licence, no foreign-military-sales paperwork delay.
EU-sovereign for primes that need it
2024–2026 EU defence procurement increasingly favours EU-domiciled suppliers across the supply chain. Helsing, Quantum Systems, Tekever, MBDA, OHB, and ArianeGroup all have stated EU-origin sourcing preferences for sovereign-tech hardware.
Aerospace-grade pedigree
Existing aerospace-programme experience already covers orbital launch, CubeSat propulsion, and certified UAV programmes. Defence qualification (MIL-STD-810H, DO-160G, NATO AQAP 2110) is an extension of that capability, not a new business.
Production cylinders qualified for defence use
| SKU | Volume | NWP | Mass | Application class |
|---|---|---|---|---|
| HDRX-005 | 0.5 L | 300 bar | 0.42 kg | Sub-1U CubeSat propulsion, micro-UAV |
| HDRX-030 | 3.0 L | 300 bar | 1.60 kg | Tactical UAV, hydrogen ISR drone |
| HDRX-068 | 6.8 L | 300 bar | 2.80 kg | Long-endurance drone, swarm asset |
| HDRX-090 | 9.0 L | 300 bar | 3.80 kg | Cargo / heavy-lift drone, ground vehicle |
| HDRX-400 | 40 L | 300 bar | 18.0 kg | Pressurant tank, ground support, missile |
| HDRX-R450 | — | 450 bar inlet | — | Hydrogen regulator, single- or two-stage |
Custom volumes, working pressures, mass envelopes, and connector configurations available on programme-specific quotation. Typical lead time: 4–8 weeks for stock SKU; 12–18 months for custom qualification.
Qualification path for defence procurement
- MIL-STD-810H environmental qualification (vibration, shock, humidity, temperature) — typically 6 months at FORCE Technology / DELTA / DTU in Denmark
- RTCA DO-160G qualification for airborne use (vibration Cat S, shock Cat B, high-altitude operation, EMI/EMC)
- MIL-STD-461G EMI/EMC for systems with electronic interfaces (sensors, instrumented cylinders)
- NATO Codification via NCAGE assignment — paperwork, 1–2 months
- Programme-specific qualification (PPAP-equivalent for primes, AQAP 2110 for NATO contracts)
- Export-control classification — Danish Business Authority (Erhvervsstyrelsen) dual-use track
Application classes
- Hydrogen-fuel-cell tactical UAV — 3–9 L cylinders + HDRX-R450 regulator. Endurance 2–8 hours typical. EU-sovereign positioning unlocks European primes (Helsing/Quantum, Tekever, MBDA-adjacent).
- UAV swarm pressurant — 0.5–3 L pressurant tanks for cold-gas attitude control across distributed swarm assets. Type IV PET enables sub-1 kg per asset.
- Special operations breathing apparatus — high-cycle, low-mass SCBA cylinders for SOF use. EN 12245 + EN 17339-derived qualification path.
- Missile pressurant systems — propellant feed pressurant for tactical missile architectures. programme-specific qualification.
- Stratospheric/HAPS platforms — ultra-light Type IV for hydrogen-fuel-cell pseudosatellite operations.
How to engage
Three reasonable starting points depending on programme stage:
- Architecture / trade-study stage — request the data pack (datasheets, mass-scaling curves, indicative cost bands) under standard NDA. Free, <1 week turnaround.
- Down-select / source-selection stage — request a programme brief (ITAR-free certification path, qualification cost estimate, lead time, named engineer-of-record). 1–2 week turnaround under NDA.
- Qualification campaign / production order — start with an RFQ specifying the cylinder volume, working pressure, qualification target, and quantity. We respond within 3 working days with feasibility, indicative cost, and timeline.
