> Modern CIWS are designed to be effective against substantially faster and more agile rockets. The thing is exactly that those drones are so slow, and low. Phalanx performance against sea skimming missiles is know to be poor. And that on dielectric, flat sea surface. Even military drones weighting few tons can fly autonomously under 100m. Ironically, it's now depressions in the terrain which will provide more air defence since they will force terrain following drones, and cruise missiles to move at oblique angles. Basically the problem is the same as with low, and slow cruise missiles, except worse.
