Subcontractor Management

As a systems provider and prime contractor in numerous large space projects, OHB System works with a large number of subcontractors, who develop or deliver hardware, software and services. The performance of the subcontractors of OHB System is essential for the success of OHB’s projects. Therefore OHB is continuously looking for the best subcontractors in terms of quality, delivery time and cost, with the goal of establishing stable partnerships and to create synergies over multiple projects.

The Department Subcontractor Management is currently responsible for the management of subcontracts with more than 120 space companies world-wide.

Current and planned OHB System invitations to tender for ESA projects (EMITS) can be found here.

Points of contact

Subcontractor management is divided into six domains. The leaders of these domains monitor and coordinate the subcontracts within their domain and are available as points of contact for companies, who would like to become subcontractors for OHB System.
