US Navy Launched Another Test Stage for Reactive Drones X-47BCommand aviation On July 29, the US Navy announced the beginning of flight tests at Patuxent River airbase of the X-47B strike UAV demonstrator developed as part of the UCAS-D (Unmanned Combat Air System Carrier Demonstration) program.


Built according to the tailless pattern, the UAV flew to 11: 00 local time and during the 35-minute flight over the Chesapeake Bay reached an altitude of 7500 feet and developed 180 nodes speed.

According to the developers, the first flight of X-47B in Patuxent River is the beginning of an important intermediate stage, the purpose of which is to demonstrate the compatibility of the UAV with the flight support system, as well as equipment for the take-off and landing of the aircraft carrier. The unique shipboard equipment deployed at the base allows the US Navy to test the vehicle on the ground before its deployment on board the aircraft carrier, which is scheduled for next year.

X-47B arrived at Patuxent River from Edwards airbase (California) in June. Testing apparatus will continue over the coming months. The test program provides for checking the accuracy of the approach to the deck of the aircraft carrier, landing with the aero-finisher and taking off with the use of a catapult on a ground installation.

The aircraft carrier's simulated environment will allow the test team to verify that the X-47B is ready for the offshore tests planned for the 2013 year.

The 7-10 in July, a team of specialists from the US Navy Aviation Systems Command conducted extensive software testing aboard the aircraft carrier Harry S. Truman (CVN-75) to confirm the concept of autonomous UAV operations aboard the aircraft carrier and prepare for the arrival of the X-47B. The tests were carried out using the King Air plane as an imitator.

The X-47B is an autonomous unmanned aerial vehicle that, at the command of the operator, performs take-off, flies along a preprogrammed route and returns to the base independently. The operator controls the actions of the X-47B using a simple display system, but does not remotely control it, like a number of existing unmanned systems.

A six-year contract worth 635,8 million to build the X-47B UAV, the US Navy signed with Northrop Grumman 1 August 2007 of the year as a result of a tender. The system UCAS-D will include two subtle UAVs, two control points and a support point.

The goal of the X-47B development program, which will not be put into service, is to demonstrate the possibility of using a low-profile jet drone based on board the US Navy aircraft carrier to perform information gathering, observation, reconnaissance, and strike operations. The program must prove the ability of the device to autonomously perform takeoff and landing on the deck of an aircraft carrier.

        It’s just that Americans are used to blowing the whole world about what they have and create their image.
        And with us, everything is secret. Prototypes have already been created and tested, just in the series they are not.
        And after a couple of years - the news is on the move - we are waiting for the latest shock drone in half a year. Already in operation.
        And this despite the fact that there are still a lot of Soviet projects and developments. Modify to a modern level and forward.

            On July 28, 2012, JSC "Sukhoi Civil Aircraft" (SCA) in Ulyanovsk finally signed an act on the transfer of the passenger aircraft Sukhoi Superjet SSJ100-95В (production number 95017, serial number 017) to JSC "Aeroflot - Russian Airlines". repeat
            This aircraft became the tenth serial SSJ100 aircraft put into operation and the ninth received by Aeroflot. fellow
            In Aeroflot, the plane received registration RA-89009 and the name Vasily Borisov.



            This aircraft made its first flight on April 4, 2012, but its transfer to the customer was delayed due to revealed defects in painting, as a result of which the aircraft was returned to Ulyanovsk at OJSC Spektr-Avia for "refinishing". bully

            At present, the tenth SSJ100 intended for Aeroflot (serial number 95018, serial number 018, registration RA-89010, name "Boris Bugaev"), which made its first flight on July 12, is on the painting in Ulyanovsk.

            In addition, a new aircraft with the serial number 95021 (serial number 021), which was previously intended for delivery as the second board of the Armavia airline and had an Armenian registration EK-95016, is under testing in Zhukovsky. hi

          It's just that Americans are used to blowing the whole world about what they have

          Hello Eugene!
          For Americans, this is a completely normal approach.
          - It didn’t work out - you need to make of this show and cover (at least part of the costs).
          They have more than enough experience in this, onlookers even more.
          Therefore, they need to be evaluated only when the product goes into series.
          By the way, here is one example

          From 1946 to 1956 (8), a supersonic aircraft was developed (in August 1954. The speed of sound was achieved, but there were problems - not solved, with shaking during takeoff)
          One of the problems - what gave him buoyancy (wing area) did not allow him to be used during excitement. The project remained - a toy for the show.
          And after 1956, Mr. Amer was eager to create not a seaplane but a flying boat, but after developing cruise missiles, all this was sent to the archives.

      In addition, we have already planted one of their super newest drones with Soviet equipment - do you think this one will not be planted or will it not be knocked down?
      Not really - why is it so huge?
      What could be stuffed there? And most importantly, why! Now any Malomalsky rich country is arming itself to the teeth and, first of all, with air defense systems. And taking into account the cost of this bandura - I do not think that there will be any sense from him.

          As far as I remember, professor, you disputed the very possibility of jamming the "military" GPS signal, but then what is it
          "Today, more and more devices capable of jamming the GPS signal are appearing on the arms market. In the US, even criminal gangs have begun to use such jammers." and further
          “As part of the Sentinel project in the UK, since January last year, a network of 20 roadside sensors has been detecting attempts to jam the 5 GHz frequency band reserved for GPS. One sensor on a busy highway has recorded more than 60 jamming cases in the past six months, and the network has recorded about 10 attempts per month.
          Inexpensive GPS silencers plugged into the vehicle electrical system of the 12 B can be purchased relatively easily in the UK. They are used by truck drivers trying to trick corporate tracking systems, and car thieves.
          The growth in the use of jammers also affects legitimate users, since these devices mask GPS signals within a radius of 200-300 meters. The Sentinel project is going to improve the system so that it can identify drivers using mufflers. "

          And here it is. "However, Richard Langley, a GPS expert at the University of New Brunswick, noted that Iranian military specialists did not need to break the P (Y) code. Quite it is enough just to drown out the frequency at which the "military" GPS signals are transmitted with a powerful transmitter, which would cause the RQ-170 flight control system to switch to autopilot mode, and then, using the same powerful "false" signal, land the device in the place where the Iranian military saw fit.
          In other words, the fact of the theft of an ultra-modern flying spy machine worth $ 6 million does not look so incredible, since the mechanism of such an operation is recognized by quite real technical experts, and not only news publications are not shy about declaring the fact. "So something like that ...

            As far as I remember, professor, you disputed the very possibility of jamming the "military" GPS signal

            You do not remember correctly. I dispute the possibility of replacing a closed GPS signal and the possibility of jamming a broadband encrypted control channel and exchanging information, in other words, control interception. GPS jammers have long been in retail at ridiculous prices (Car Cigarette Powered GPS Blocker - Black (DC 12V)).

            and then, using the same powerful “fake” signal, land the device in the place where the Iranian military considered it necessary.

            To get a "fake" signal, you must at least crack the codes (Skype codes are not hacked by anyone - neither China nor Russia) of the encrypted signal.

            the fact of theft of an ultra-modern flying spy machine worth 6 $ million does not look so incredible

            Firstly, this is not a fact, and secondly, it is simply not realistic for a number of the reasons I listed earlier. I do not see the need to repeat myself.

              Skype - listening is possible

              Before the German police recognized the impossibility of monitoring VoIP conversations, a British specialist released a prototype of a VoIP listening program. Called SIPtap, the created program monitors all streams using the VoIP protocol and records them in WAV format for remote study. All that is needed for a successful listening is to infect the victim's computer with a special trojan. The development of the program began in August with the help of VoIP expert Peter Cox, a consultant in the field of Internet telephony.

              It should be noted that SIPtap was originally created during Cox's work on VoIP security and exploring the possibility of countering spyware through programs like SIPtap. According to Cox, now VoIP is just beginning to develop, however, in many companies, Internet telephony has already become widespread.
              "Companies using VoIP [wrongly] think they are secure," Cox said. SIPtap shows the opposite and demonstrates that companies will soon have to pay as much attention to VoIP security issues as “ordinary” protection against viruses, Trojans and other malicious modules. http://www.inattack.ru/news/skype-vozmozhno-proslushivanie/2455.html#.UBlYeGE0Nq

      The USA is planning and methodically moving towards its intended goal.

      It depends on what the goal is and by whom. I do not consider myself to be either “cheers-patriots” or “all-pro-Bastards” Drones, of course, this is serious, but, as you know, for every tricky thing ... there is ... with a screw. “Back in 1997, at a Zhukovsky International Air Show, a Russian company demonstrated the first transmitter of electronic interference to GPS and GLONASS systems, which interrupted the operation of their receivers. As a result, they lost the ability to measure the coordinates of the objects on which they were installed. This jammer made a splash in the West. The first to evaluate the danger of new items for their military equipment was the Americans. The Pentagon bought dozens of such “jammers” and tested them with its military equipment, whose operation was based on the GPS system. It turned out that high-precision weapons (cruise missiles, guided bombs with the JDAM system, etc.) of the United States and other NATO countries under the influence of interference ceases to be high-precision. The most important conclusion immediately followed from this: if a country wants to protect itself from high-precision weapons, then over its entire territory with the help of "jammers" it is necessary to organize a continuous electromagnetic field of interference. In this case, the correction of the flight of high-precision weapons using the GPS system will become impossible, and huge misses will follow regarding objects that needed to be destroyed. They passed the combat test in the spring of 2003 in Iraq, when at the very beginning of the war, with the help of precision weapons, it was not possible to hit important targets. On the fifth day of the campaign, a loud international scandal broke out with accusations against Russia (you can find out more about it on the Internet). And only after the Americans over the next five days tentatively established the places where the jamming transmitters were and carpeted bombed whole areas with jammers, the war went according to plan. The incident showed the whole world how, using a fairly cheap means, it is possible to actually reduce to zero the effectiveness of a variety of military equipment using a satellite navigation system. When the question arose of how to deal with UAVs that are small in size, have a small reflective surface for radars, and have a low altitude, it turned out that the only way to deal with them is with the same “jammers”. The creation of a field of electronic interference for the GPS system, in addition to neutralizing high-precision weapons and disrupting command and control, leads to an additional effect - to neutralize UAVs. Another important task in which drones can play a decisive role is the paralysis of aircraft carrier actions. Their functioning has a weak link - returning aircraft with a limited fuel supply. If you plug all the “eyes” and “ears” of the planes returning to the aircraft carrier, then they will not be able to board the ship in a timely manner and, after running out of fuel, will be lost. This concept of paralyzing the actions of aircraft carriers was first presented at an air show in Le Bourget in the summer of 2007 by one Russian company. The equipment for its implementation was also shown there. The result is a shock among the American representatives at the exhibition and the staff of the US Embassy in France, as the second “leg” is kicked out from under the US military power.

    The device is certainly good, but it costs like a golden calf, so losing it is like dropping an iron on your foot. With the rapid development of high-altitude air defense systems, it is simply useless and something expensive to use against Aboriginal people.

        And this is he - kind of already alive and very very angry at the Americans and their UAVs !.
        At least ours have adequate dimensions. Already +. Yes, and so simple - Handsome!

    Something that people who know know about this news are indifferent. If you recall Buran, then he can not help but have younger sisters or brothers. Avia models for fools.

    Although it’s a good thing, we now need to deal with the vital ones, purchase S-400, planes, ships, and then deal with these trinkets.

    By the way, I’ll draw attention to the fact that proactively none of you noticed in the article
    X-47B is an autonomous unmanned aerial vehicle that takes off at the command of an operator, flies along a pre-programmed route and independently returns to the base. The operator controls the X-47B using a simple display system, but does not remotely control it.like a number of existing unmanned systems
    These are already explicitly declared elements of artificial intelligence. And, of course, if 95% of all control tasks and actions do not rotate between the operator and the board on the radio beam, but are closed inside the board, no Iranians can even intercept such a bird. There is simply nothing to grab. And if you remember the Faraday cage, then burn out the onboard brains with all kinds of EMP, too, the task is not one of the most real

    The United States and drones ... Hmm .. And if China begins to build such tens of thousands? Our minister Dmitry Svet Anatolyevich Medvedev allowed the latter to fly in our airspace and take pictures of our military facilities. And when the coordinates are known in advance, then you can not be afraid of UAV control interception. If I'm not mistaken, then use inertial guidance + artificial intelligence + unguided ammunition = completely ignoring the enemy’s electronic warfare. Of course, given the multi-echelon nature of our air defense / missile defense, it will be unrealistic to break through the S-300 \ 400 \ 500 and Pechora, Buki, Tunguska complexes, BUT ... But will we still have enough missiles to fight manned aircraft ??? The end of hysteria ...

    If the United States, having 11 aircraft carriers, will equip about 35-40% of such drones, then using one or two of these on a "ram" to punch a hole in the air defense, the rest behind it can inflict colossal losses on the enemy hi

        Which adversary? How are UAVs controlled?
        To any enemy of the USA. This drone is a robot, it has on-board computers, there are programs on which it will fly in autogyma mode. It’s like in the movie Terminator 2, everything is agglomerated, there cyborgs go with machine guns shoot people, and flying devices with guns hi

    The UAV is not a wunderwaffe ... "According to the reports of the military personnel operating this complex, many shortcomings were revealed that significantly affect the implementation of the assigned tasks:
    1. The performance characteristics of the UAV do not match
    declared (maximum flight altitude - 3300 m, and during practical
    launches found that the optimal resolution for video and photography
    from a height of 800-1100 m, the maximum flight range is 10km,
    but at low temperatures it is - up to 6 km.
    2. UAV control is provided by the operator in direct line of sight.
    In case of signal loss, the design provides for the UAV to return to the point
    launch on the shortest distance that in mountainous conditions
    can lead to a collision with obstacles (especially when starting in
    gorges)
    3. Launching is not possible in conditions of low cloud cover, foggy and rainy weather, wind speed 5 m / s or more, air temperature minus 3-5 degrees Celsius (actually).
    4. There is no topographic basis for the areas of responsibility 4, 7 WB and 1327Ц (pripspn) (electronic maps of the globalmap or splane system — download from the global Internet is necessary), was installed in Kolomna during the training of UAV operators, for which a presentation of the FSB of the Russian Federation for South Eastern Military District was drawn up .
    5. When climbing (up to 150-200m) and landing, the UAV flight does not
    controlled by the operator, which imposes additional requirements for
    selection of the launch site (landing).
    6. With a sharp increase in the speed and direction of the wind, when flying over a mountainous area, the UAV spontaneously stalls into a “tailspin”.
    7. The determination of the coordinates of one’s location and reconnaissance objects is carried out according to the system, which makes it possible to track it with foreign intelligence
    8. At low temperatures, performance decreases
    UAV batteries, which reduces the time and range
    flight. "http://anna-news.info/node/6152

    With all the pros and cons, the UAV has its place in the future. And to develop this topic for the future, we must now!
    I want to make a reservation right away that UAVs are not a panacea. But the range of tasks that they will be able to perform is simply huge, both in the civilian sector and in the military!
