The US Navy is using $10 million missiles to shoot down $10k drones. Do the math. They could deplete US Navy stockpiles for trivial costs. They have turned the US Navy's strength into its own weakness.
What people don’t realize is that the US hasn’t actually fought under LSCO conditions since early Vietnam, as regardless of the scale of the deployment the ROI and thus the tactics that can be employed were mostly limited to LIC/PKO.
