Why It Matters

Built for
Defence Supply Chains

Defence prime contractors cannot afford supply chain failures. Every component we deliver is backed by a certified quality management system that meets NATO standards — not just commercially.

Our AQAP 2120 certification means your procurement team can onboard us with confidence. We meet the audit requirements, the documentation expectations, and the zero-margin-for-error culture of defence manufacturing.

Direct line to the Managing Director on every contract. No bureaucracy. No layers. Full accountability.

Additionally, our Managing Director holds a personal licence under Austrian § 139 GewO (Weapons Trade Act) — issued by WKO Oberösterreich. This means GRO-EB operates with full legal authorisation in the weapons trade sector across Austria and Germany, a credential most subcontractors in the DACH region do not hold.
