Defence Manufacturing
First In Service manufactures mission-critical precision components for the defence sector from Tallinn, Estonia, with full material traceability, strict quality control and documentation to defence specifications. The company is a member of the Estonian Defence and Aerospace Industry Association and works to ISO 9001, EN 1090-2 and EN ISO 3834-2.
Supply-chain origin is now part of the specification.
Defence procurement has changed. Where a component is made, who owns the plant, and whether the chain of custody survives an audit are no longer administrative details — they are qualification criteria. A supplier who cannot evidence origin and traceability is a supplier who cannot be used, whatever the price or the tolerance.
EU and NATO-country manufacture, one facility, full traceability.
First In Service manufactures in Tallinn, Estonia — EU member state, NATO member, and 20 km from a deep-water port. Every component is traceable by heat number from material receipt to final inspection, and because fabrication, machining, surface treatment and assembly all happen inside one 18,000 m² building, the chain of custody never leaves our control or our documentation system.
