NATO Business Opportunity: Force Lethality Enhancement eXtended (FLEX) Modelling and Simulation Study

Headquarters, Supreme Allied Commander Transformation (HQ SACT) is initiating Force Lethality Enhancement eXtended (FLE(X)), building upon the outcomes of the initial FLE study conducted in 2025. FLE focused on identifying novel options to deliver NATO Defense Planning Process (NDPP) Capability Targets (CT) in whole or in part. FLE(X) broadens the scope to include exploratory questions that look at the evolving operational problem sets that drive requirements and then CT. FLE(X) aims to identify new ways and means of achieving operational effects and to accelerate the translation of innovation into operational capabilities. FLE(X) will explore how the rapid adoption of new and emerging technologies, including robotics, autonomy, artificial intelligence, advanced networking, and precision-strike systems, can enhance the lethality of the NATO force and improve survivability, agility, sustainability and affordability. The studies will seek to deliver evidence-based insights that can support national decision-making on capability options and inform future NATO capability development including force-design activities. The contractor will provide analytical support through mission analysis, modelling and simulation, and structured evaluation of operationally relevant use-cases to identify credible opportunities for enhancement. This work will form part of a broader evidence base developed by ACT and participating Allies to inform the transformation of the Alliance’s military instrument.
