The X-47B is the only stealthy UAV under development that is currently acknowledged by the Pentagon–unless you count the recently revealed Predator-C, which General Atomics says has been built with the company’s own funds.

However, there is a hidden history of secret UAV programs in the U.S., and AIN believes one of these is now going operational. It could be a UAV with a reconnaissance mission produced, in partnership, by Northrop Grumman and Lockheed Martin. AIN also believes Boeing probably has received “black” funding for follow-on development of a UCAV based on the X-45 series.
