Sopra Steria maps the new reality of European defence

The shift in strategic value is stark. Recent conflicts in Ukraine and the Levant demonstrate that software cycles measured in weeks now outpace hardware systems designed to last two decades. Sopra Steria’s latest trend book highlights this imbalance with telling figures: the global cost of disinformation has hit $417 billion, while European capability requirements under the Readiness 2030 plan are estimated at €800 billion. The economics of attrition are equally lopsided, with a 1-to-20 cost ratio between low-cost attack drones and the interceptor missiles required to neutralize them.

To regain the initiative, the firm outlines a framework centered on three pillars: managing saturation, orchestrating multi-domain action, and building industrial longevity. These goals require moving beyond mere hardware acquisition toward a model where sovereign AI and quantum technologies are integrated into combat at scale. For European agencies and defense industries, the analysis suggests that strategic autonomy has transitioned from a long-term goal to an immediate operational necessity. Success in this environment depends on how quickly forces can link disparate systems, data, and personnel to outpace an adversary’s decision-making loop.
