Synthetic Training as Europe’s Readiness Multiplier

European and NATO planners now treat synthetic training—live-virtual-constructive simulation integrated with extended reality and digital twins—not as a budgetary convenience but as a structural enabler of readiness in an era of munitions scarcity, platform fatigue and multi-domain complexity. High-fidelity LVC ecosystems allow forces to rehearse high-intensity scenarios without consuming ammunition stocks, exposing sensitive capabilities or degrading equipment, while simultaneously integrating land, air, maritime, cyber and space effects in ways that live ranges cannot safely replicate. This analysis examines how EU instruments such as the European Defence Fund and SAFE intersect with NATO’s digital transformation agenda to build federated synthetic training networks, and assesses the industrial dependencies—cloud infrastructure, GPUs, game engines, rad-hard electronics and secure data standards—that will determine whether Europe can scale a sovereign, interoperable training architecture through the 2030 horizon.

Synthetic training – incorporating live-virtual-constructive (LVC) simulations and extended reality (XR) – is explicitly framed by NATO and EU authorities as a readiness multiplier, not merely a cost-saving measure. In allied doctrine, high-fidelity simulators enable units to rehearse complex scenarios more frequently and safely than live exercises permit. NATO’s training vision calls for “a NATO-wide federation of national synthetic mission training capabilities” delivering “regular and frequent access to high quality, secure, immersive operational training…at team, collective, joint and coalition levels”【S4】.

In practice, synthesised training preserves critical stocks by reducing live ammunition expenditure and platform wear. Analysts note that simulators are “more cost efficient” and involve “less wear and tear” on equipment than live firing【S3】, while allowing training “out of range of foreign spies”【S3】, thereby maintaining operational security.
