    Y los chinos y rusos salen diciendo que están cerca de Estados Unidos. Con los apartes que he visto, sólo con eso, veo que mejor vayan bajándose de esa nube. Los gringos no les llevan años luz de ventaja, les llevan siglos luz...

    Todas las fotos fueron tomadas el mismo año (2007) por diferentes personas en la misma región cerca del "CHINA LAKE NAVAL WEAPON CENTER" .

    Esto me lo tomo muy en serio por saber quienes están detrás de las divulgaciones (La misma NASA en algunos casos).

    The Smartest Unmanned Vehicles You’ll Never See

    Self-driving cars and flying drones may be dominating the headlines when it comes to autonomous robotics, but advances in autonomy have also had an impact on sea vehicles.

    The Marlin UUV can create 3D models of its undersea environment for commercial and military operations.






    While self-driving cars and flying drones have dominated headlines onrobotics, advances in underwater technology have quietly evolved the use of unmanned vehicles under the surface of the sea. 

    Advanced robotics technology, including communications and navigation, has enhanced UUVs’ ability to guide themselves on their missions–at farther distances and in harsher environments. Whether being used by military or commercial operators, UUVs are changing the way we explore the 140 million square miles beneath the sea.    

    Unlike its ground and air counterparts, unmanned underwater vehicles (UUVs) face a whole new set of physics that require them to operate with significantly less human control. 





    THE BRAINS BEHIND THE OPERATION





    “Navigating the undersea environment has a lot of variables that can affect a mission: currents, underwater obstacles, even fishing nets,” explains Frank Drennan, director of Advanced Programs and Business Development for Lockheed Martin. “When our vehicles encounter something they don’t expect, their onboard ‘brain’ allows them to collect relevant data and either continue or alter their mission accordingly.”




    One underwater vehicle with a mighty brain is the Marlin® UUV, using advanced sensors and high definition video to create 3D models of its undersea environment. Marlin is capable of plumbing the ocean depths to offer quick and efficient underwater surveys and inspections while sailors and commercial operators remain safely above water.

    And because Marlin doesn’t need a human at the controls, it can explore the ocean depths, conducting pipeline inspections, bottom debris surveys and underwater facility inspections. 





    ROBOT TEAMS IMPROVE SURVEILLANCE

    Future UUV operations could include multiple underwater systems, like the Marlin, as well as other surface or aerial vehicles.






    Collaborative operations among multiple unmanned systems are on the rise. Different unmanned aerial systems have worked together to accomplish numerous missions, ranging from firefighting to reconnaissance. Unmanned aircraft have autonomously lifted and delivered unmanned ground vehicles to complete delivery or surveillance missions.

    In the future, UUVs could work collaboratively with other underwater vehicles, or team up with unmanned surface vehicles and unmanned aerial vehicles. Together, these systems could provide an eye in the sky and an eye under the sea to help provide an integrated picture of the environment.

     “New uses for UUVs will continue to proliferate as the technology matures,” said Drennan. “We’ll continue to develop a wide variety of payloads that can be rapidly integrated into UUV systems, giving customers the ability to use those vehicles for multiple missions.”





    TRANSFORMING TORPEDOES' ABILITIES

    Torpedo technology has evolved to a point where these weapons can serve as UUVs beyond their traditional missions



    Thanks to continually evolving technology, Lockheed Martin is leading the way in transforming torpedoes to tackle missions beyond their traditional charges. While weapons like the U.S. Navy’s formidable Mark 48 Mod 7 torpedo are known for packing a powerful punch, they also have the potential to behave like UUVs.

    The Mark 48 Mod 7 has a cutting-edge guidance and control system that allows it to operate autonomously. In the future, we are looking to advance the torpedo into a multi-mission vehicle that could be used to collect real-time information that is valuable to success in undersea missions.

    As future undersea missions surface, Lockheed Martin’s portfolio of high-tech unmanned underwater systems will evolve to meet the next generation of commercial and military challenges. These unmanned vehicles will continue to push the boundaries in endurance, power, collaboration and expeditionary capabilities to travel farther, longer and smarter than ever before.

    Inside The Roc's Lair

    Source: http://aviationweek.com/blog/inside-rocs-lair

    The massive size of the carrier aircraft now in assembly at Mojave, California, for Stratolaunch Systems’s space launch program is apparent for the first time in these rare stills taken from footage shot for a recent news story by KGET 17, a Bakersfield TV station.





    One of the two enormous twin fuselage sections under assembly. Individuals working on the structure are ringed in red circles for scale.

    The NBC affiliate was granted unprecedented access to film the gargantuan vehicle, dubbed ‘Roc’ after the giant bird of prey in Middle East mythology, as part of an overview report on space-related developments at Mojave. Although Stratolaunch has produced computer-generated images and videos of the Roc, the TV footage is the first time images of the real vehicle in a substantial state of completion have been shown.





    Another view of a boom with a worker circled for scale on part of the wing section.

    Built for Stratolaunch by Scaled Composites, the Roc will be the largest aircraft ever made with a wingspan of 385 ft. This compares to 320 ft for the Hughes H-4 Hercules (Spruce Goose), 290 ft for the six-engined Antonov An-225, 262 ft. for the Airbus A380, and 225 ft. for the Boeing 747-8. Powered by six reconditioned Pratt & Whitney PW4056 engines salvaged along with other parts from two ex-United Airlines Boeing 747-400s, the twin-fuselage carrier aircraft resembles a vastly enlarged version of the Scaled-built WhiteKnightTwo developed for Virgin Galactic.





    The deep chord of the center wing section and narrow cross section of the aft fuselage booms is evident in this overview.

    In the news report, Scaled Composites president Kevin Mickey says the company has so far built “roughly 200,000 lb. of composite structure” for the vehicle. He adds for effect that if the Roc was positioned on the centerline of the 50 yard line of an American football field the wingtips would hang over the goalposts “roughly 15 ft. on each side.”





    Each of the twin fuselages of the Roc is 238-ft. long and, when complete, will be supported by 12 main landing gear wheels and two nose gear wheels for a total shipset of 28 wheels. The vehicle will be flown by a three-person crew from a cockpit situated in the right hand fuselage. The three-stage Thunderbolt rocket will be carried aloft for launch mounted beneath the wing center section.





    Flight tests are scheduled to begin in around a year’s time, with initial launch operations starting in 2018. According to the latest information from Stratolaunch, the Orbital Sciences-built Thunderbolt will be 131-ft long, and weigh around 550,000 lb. Overall weight of the Roc and Thunderbolt will be 1.3 million lbs. The launch vehicle is designed to put 13,500 lb. into a 220 naut. mile, 28.5 degree (LEO) orbit.  Payloads will be enclosed within a 16.4-ft diameter fairing. The three-stage vehicle will use ATK-provided solid rocket motors for the first and second stages, while the third will be powered by two liquid-fueled Aerojet Rocketdyne RL10C engines.

    Bill Uhouse sirvió 10 años en el cuerpo de marina como piloto de combate, y durante años en la Fuerza aérea estadounidense en la base Wright-Patterson como piloto de pruebas "dog-fight" de aeronavespoco convencionales. Más tarde y por los siguientes 30 años, Bill llegaría a trabajar para contratistas de defensa como ingeniero especializado en sistemas de propulsión antigravitacionales en simuladores de vuelo de aeronaves poco convencionales "exóticas" y  discos volantes.

    Bill testificó que el primer disco que voló fué uno al que se le hizo reingeniería y que se estrelló en Kingman Arizona en 1958. El ingeniero además aseguró que los extraterrestres del disco presentaron la nave ante el gobierno de los Estados unidos, más tarde esta nave fué llevada a la recién construida área 51 y que los ETs que acompañaban el disco volante fueron llevados a las instalaciones de lo Alamos. La especialidad del señor Uhouse fué la de analizar la cabina de vuelo y los instrumentos de vuelo. El entendió el campo gravitacional y el tipo de entrenamiento que debían experimentar las tripulaciones para vivir en la antigravedad. Este científico llegó a reunirse varias veces con un extraterrestre que ayudó a los físicos e ingenieros con la ingeniería del aparato.



    Bueno, no se si ustedes han visto discos en forma triangular, pues en verdad estos discos no son extraterrestres, son en realidad versiones humanas de los platillos volantes.
