Naval warfare is in the nascent stages of another paradigm shift, the first time since the adoption of the aircraft carrier. The evidence of this upheaval is starkly illustrated in the Ukrainian conflict, where cruisers are now vulnerable to crudely assembled weapons. Global maritime freight is frozen by underequipped proxy regimes wielding inexpensive drones. These examples underpin a shift in the unit economics of war, where low-cost autonomous platforms are toppling conventional capabilities.
