US Navy before the summer 2000 years to conduct independent development of a new UAV to carry out missions from aircraft carriers. Further developed by the project was handed over for analysis to companies like Northrop and Boeing. The study lasted for 15 months.

Designed by naval aircraft had to solve many problems. First of all, it was laid out the body and chassis of the device to withstand the corrosive marine environment. Also, the machine equipment was resistant to electromagnetic interference. It should be noted that the Navy was interested in UAVs, which could carry out exploration in the protected space and identify enemy targets, after which he had to air strike.

It was originally planned on the basis of unit X-47V make unobtrusive maneuverable fighter. Yet experts say that this machine can not perform the job required her to conduct air combat for at least another ten years, as yet so thoughtful technology. To create such a machine you need to make a lot of mathematical calculations the unit behavior.

As a result, the Navy signed by Northrop in 2001 year on the further development of the Marine version of the UAV X 47A. Custom demo layout looks like an arrowhead, because the unit does not have a tail and vertical tail. Wings apparatus have 55 degree sweep. Breadboard model is equipped with three-point system chassis. For flying machine has six working planes, including two ailerons and four inleyda, this small additional structures at the ends of the flap.

The power plant is represented by a JT15D-5C bypass turbojet engine, which is manufactured by the Canadian company Pratt & Whitney. The engine delivers 14,2 kN of power. The exact same engine is used on the Aermacchi S-211 aircraft. The power plant is located in the tail section. The entrance channel is located on top, it has a diffuse structure, this allows you to hide the device on radars. The exhaust gases enter a conventional exhaust pipe, which does not hide the car in the infrared spectrum. 

Almost all parts of the airframe power X-47 made of composite materials. The assembly of the aircraft is operated by Scaled Composites, which has relevant experience and necessary equipment. The whole structure consists of 4 parts, which are divided in the middle. UAV X-47 30.07.2001 years was introduced, and the first flight was made in the winter 2003 years in California. Under the program, the development machine is equipped with the appropriate weapons, which is installed in two bomb bay located on the sides of the engine. In each set, one bomb bay bomb weight in kilograms 225.

In testing machine has demonstrated the possibility of landing on the deck of a ship without a brake hook. There is also a possibility of mooring without disabling stealth mode. It was thought out and worked out system of management, it was made for resistance to the wind in sea conditions.

The first production copy of the UAV X-47 16.12.2008 years presented at the company 'Northrop Grumman. " The US Army made the first order of such machines, he was executed in 2009 year.

Deck UAV X-47 in combat configuration took off in the winter 2011 of the year on the basis of Edwards. The flight continued for 29 minutes, while he climbed to the height of 1500 meters without removing the chassis. The flight was excellent, the device worked with all the tasks. Takeoff from the deck of the aircraft carrier "George Bush" X-47 unmanned aerial vehicle made in May 2013, after which further tests continued.
