Embodiments of a method and apparatus for assigning electromagnetic-spectrum (ES) jamming assets are generally described herein. In some embodiments, the method includes dividing an electronic warfare (EW) support area into a grid. The method may further include determining a vulnerability area (VA) of the entity based on planned route information of the entity within the EW support area. The VA may include portions of the grid. The method may further include assigning a first jamming asset to the VA based on a coverage capability of the first jamming asset. The coverage capability may include a number of contiguous portions of the grid.

The method of claim 11, further comprising: receiving updated location information of the entity; andproviding jamming signals in a portion of the VA based on the updated location information of the entity. 15. The method of claim 14, further comprising: providing jamming signals in a first portion for a time duration subsequent to receiving a notification that the entity has left the first portion. 16. The method of claim 14, further comprising: suppressing jamming signals in a first portion responsive to receiving a notification that the entity is within the first portion. 17.
