| Sumario: | We are entering a Third Drone Age, one characterized by full spectrum drone warfare (FSDW). FSDW is not one single technology in one domain, but a systems revolution of autonomous air, ground and maritime machines that learn, adapt, and fight as one. NATO members are noting this FSDW transformation and are heavily investing in unmanned systems across domains, yet without a shared framework for integrating them. The question is not whether to buy drones to strengthen NATO's deterrence posture and strategic autonomy, but whether NATO members can build the doctrine, software, supply-chain and allied institutional capacity to deploy them more effectively than their adversaries. Put simply, mass alone is not an effective strategy, and a doctrinal shift is needed. This policy paper identifies two major variables that will determine whether FSDW will deliver military advantage in future wars: mature cross-domain unmanned teaming and effective doctrinal adaptation. States that achieve both technological and institutional change gain decisive operational advantages. Those that simply accumulate platforms without updating doctrine risk spending heavily while falling behind. Combining these variables produces four possible futures for NATO out to 2040, from full FSDW integration to platform stagnation. The most pressing risk is technology without strategy—a scenario where mature hardware is paired with outdated doctrine.
