Specialists in Production & Spares Requirements…

Supporting both current and out-of-production commercial and military programs, we specialize in rapid response for AOG requirements and emergent demand for medium-to-high complexity, composite details and structures.

We operate blue streak manufacturing supported by state-of-the-art ERP systems, with dedicated program managers to ensure the most challenging requirement dates are met. Where rapid tooling is required, Additive Layer Manufacturing (ALM) techniques are used to overcome lead time contraints.
