The fragmented nature of the European defence industry has historically been and continues to be a prominent issue hindering its evolution. It is financially untenable, fostering duplicated systems and redundancies that induce unnecessary costs. It is also strategically problematic, impeding collaborative and cooperative efforts while preventing interoperability. At a time of a strategic shift in the European Union’s (EU) security and defence, the time has come to capitalise on the momentum and rejuvenate the European defence industry. While the work of European institutions is promising, substantial efforts will be necessary to carry this momentum further. Fostering a culture of synchronised efforts and joint projects will be the key to overcoming the bottleneck of fragmentation, unravelling at last the full potential of the European defence industry.
