This does not make conventional weapons obsolete. Directed energy systems depend on targeting data. Low-flying drones skimming sea clutter can complicate radar discrimination. Environmental factors, geometry, and deconfliction with friendly interceptors introduce constraints. In a complex battle space that includes ballistic missiles, cruise missiles, and surface threats simultaneously, commanders must carefully coordinate engagement sectors to prevent interference between systems.

For example, a microwave beam does not distinguish between hostile and friendly electronics. If a defensive missile were pᴀssing through an active sector at the wrong moment, deconfliction timing would be critical. Modern Aegis combat systems are designed to automate much of this coordination, calculating engagement windows in milliseconds.
The most stressing scenario for any fleet is not a single drone wave, but a combined-arms attack.
