They have been beautifully re-purposed. Latest version basically got completely refurbished airframe to "reset" fatigue cycle material limit which typically limits the life of the airframe (# of flight cycles before overhaul/maint/repair required due to flight loads).

If you can fly high enough, then the ordinance has the ability to fly a certain trajectory to its target using the airflow over its control surfaces (unpowered, no rocket engine).
