Except that the X-47 (X stands for experimental, remember?) is NOT entering the fleet… after it completes the series of arrested landings aboard later this year, the USN intends to retire this experimental prototype.
They have decided to not even do the “automated mid-air refueling” tests they originally planned to do with the X-47B… they are going to use a manned biz-jet that is equipped with an “autonomous control system” that mimics the system aboard the X-47B.
Then the USN is going to solicit bids from industry for the actual carrier-based UCAV that will become operational aboard USN carriers.
