They stole the Comanche drawings ?
Only difference is one country cancels them and the other gets serious into turning it into a reality like the Su-70 and X-47B. Although it would be interesting if the black ghost does become a serious project I believe the comanche was too expensive.
Some news.

AuroraFlight Sciences, a subsidiary of Boeing Corporation, has unveiled a new X-Plane aircraft based on AFC technology. AuroraFlight Sciences has unveiled an aircraft design based on Active Flow Control (AFC) technology. It will enable the aircraft of the future to become more agile. Prior to this, developers were asked to design and build an aircraft that could maneuver without the aid of movable control planes.
In the last century, aircraft control, as you know, was carried out using movable controls, such as ailerons and rudders: if you change their position, the shape of the wings or tail will change, and with them - the air flow around and, therefore, air pressure. The purpose of the moving surfaces is to control the maneuvering of the aircraft. But on the other hand, the presence of such movable controls implies the appearance of external seams in the structure, which are easy to detect using radar. The question arose - is it possible to create a seamless plane? Then it would have been harder to spot. In addition, in this case, it would be possible to reduce its weight, size, simplify the structure and reduce the cost compared to aircraft that use movable control planes.
And the other day, AuroraFlight Sciences presented a mockup of a new aircraft X-Plane, developed by order of the DARPA Advanced Research Agency of the US Department of Defense within the framework of the CRANE project (Control of Revolutionary Aircraft with Novel Effecters - Control of a fundamentally new aircraft using innovative executive devices ).
While the "zero phase" of development has been announced - AuroraFlight Sciences, together with DARPA and the University of Arizona, will explore various options for implementing active flow control. According to the terms of reference, the developers are invited to design and build an aircraft that could maneuver without the help of movable control planes. Such an aircraft should be fully ready by 2024. Theoretical work on the creation of AFC technology was carried out already in the early 1900s. But a special interest in them appeared after the Second World War. According to Daniel Miller, Senior Scientist for Aviation Systems and Aviation Research at Lockheed Martin, some of the most significant developments have already taken place in one of the company's experienced divisions - Skunk Works. (We add that Skunk Works has over fifty patents in AFC technology, and Lockheed Martin has even included some AFC elements in its SR-71 Blackbird and F-104 Starfighter aircraft.)
