The ISR capabilities of naval strike groups are provided by a host of naval, joint, and national sensor systems in space-based, airborne, surface, and subsurface platforms, and by a number of ground- and ship-based systems for the tasking of sensors and exploitation of sensor data.

Finding: The current ISR capabilities of naval strike groups have a shortfall in persistent ground and sea-surface surveillance. Navy and DOD programs in progress will improve these capabilities significantly but will still leave gaps.
