In 2020, the companies DOC Offshore, Media Mobil, OHB and Harren&Partner joined their forces in the German Offshore Spaceport Alliance on the basis of their unique competencies in their respective fields of activity in maritime offshore and space projects. The concept foresees a preparation area in Bremerhaven, Germany, and a mobile launch and control infrastructure on two ships. The fully integrated launcher is transported to the launch site in the offshore German exclusive economic zone where the launcher is erected and prepared for a launch. The infrastructure and the operational concept is kept flexible and agile to be able to serve different type of launchers and to offer rapid turnaround between two launches. The project has the ambitious target be ready in 2023 to offer launch possibilities for the European and international mini launcher provider to serve the worldwide growing small satellite market.
