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 presented turbojet engine type JT15D-5C, which produces Canadian company Pratt & Whitney. The engine gives the power 14,2 kN. The same engine is used on the airplane type Aermacchi S-211. The power plant located in the tail section. Input channel is placed on top, it has a diffuse type of structure, it allows the unit to hide the radar. Exhaust gases are fed to conventional exhaust pipe, which does not hide the machine 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 X-47 UAVs in combat equipment took to the air in the winter 2011 on the basis of Edwards. The flight lasted for 29 minutes, while it rose to a height 1500 meters without removing the chassis. The flight was great, the unit has worked with all tasks. Take off from the deck of an aircraft carrier "George Bush" unmanned aerial vehicle X-47 May 2013 made in the year, then continued further testing.
