IMHO, converting the carrier based armed drone program (UCLASS) into a carrier based refueling drone program (CBARS) is one of the most sane and prudent things military acquisition has done in recent times. Why push a cutting edge technology for which there is no immediate need into operational status? Why not instead harvest the low-hanging fruit, while simultaneously using it to refine carrier operations, and then restart UCAV development later when technologies have had more time to mature?
