It is crucial that the European Union moves quickly and collectively towards a Defence Union, creates a robust military structure for this purpose, and jointly purchases and maintains capabilities.

The fragmented industry can be made more effective by concentrating it in technology clusters, and financing for the expansion of capacities and companies can be better realised with European financial guarantees instead of Eurobonds.
