" IRAN HIJACKED US DRONE "





CAPTURED RQ-170 STEALTH  DRONE 

Iran's declarations that it will reverse engineer the US drone that it grounded makes perfect sense as Washington has had its aircraft duplicated before, writes Peter Grier.

“It's been done before, by a country that at the time the United States considered technologically inferior,” Peter Grier wrote in the Christian Science Monitor on Thursday.

Grier says in August 1947, the USSR paraded a Tu-4 Bull aircraft, a replica of an American B-29 heavy bomber, which the Soviet government had impounded in 1944 after the aircraft was forced to make an emergency landing at a base in the Soviet Union.

Tehran has announced that it intends to carry out reverse engineering on a US RQ-170 Sentinel stealth aircraft which the Iranian Army's electronic warfare unit successfully brought down with minimal damage on Sunday, December 4, 2011.

The aircraft was flying over the northeastern Iranian city of Kashmar, some 225 kilometers (140 miles) away from the Afghan border.

“Iran isn't going to give it (the spy drone) back … no matter how nicely President Obama asks,” Grier added.

On Monday, US President Barack Obama broke days of silence on the downing of the sophisticated spy aircraft by Iran and made a request to Tehran asking for the return of the drone.

“We've asked for it back. We'll see how the Iranians respond,” Obama said.

Following the US plea, Iran's Defense Minister Brigadier General Ahmad Vahidi made it clear on Tuesday the US spy drone would remain in the country's possession as part of its national assets.

Also on Monday, former US Vice President Dick Cheney criticized the US president for failing to destroy the spy drone, saying Barack Obama should have ordered an airstrike to quickly destroy the downed high-tech unmanned aerial aircraft to prevent the Islamic Republic from subjecting it to examination.

On December 6, two US officials, speaking on condition of anonymity, confirmed to CNN that the drone had been part of a US Central Intelligence Agency (CIA) reconnaissance mission, involving the US intelligence community stationed in Afghanistan.

They said the reconnaissance capability of the drone enabled it to gather information from inside Iran by flying along Afghanistan's border with the Islamic Republic.

The RQ-170, which is similar in design to a US Air Force B-2 stealth bomber, is designed and developed by the US Lockheed Martin Company.

Tehran says the US spy mission was a “hostile act,” adding it would lodge a complaint with the United Nations over the violation of its air sovereignty by the intelligence-gathering aircraft. It has urged the world body to condemn such contravention and adopt necessary measures to end the 'dangerous and illegal' acts.

THE FUTURE OF MODERN WARFARE


Cognitive Technology Threat Warning System (CT2WS)
Disc-Rotor Compound Helicopter 


Falcon HTV-2


Phoenix


Transformer


Vulture


LANdroids (Local Area Network droids)


ChemBots

DARPA, the U.S. Defense Advanced Research Projects Agency, funds some of the world's most far out, forward-thinking research into new military technology.
Something like Q Branch in the James Bond movies, DARPA is constantly working on what it describes as "radical innovations." But where James Bond has the character Q to build his exploding pens, DARPA often funds private companies and external organizations to develop its high-tech hardware.
It is currently funding research into, among other things, a robot ostrich, a flying car and a plane that could stay airborne for five years at a time.
While some of the technologies it is supporting might seem more suitable for science fiction than the battlefield, the fact that DARPA is willing to fund them is a sign they are at least possible -- if not always plausible. Don't forget, DARPA's Arpanet program is widely credited as being the precursor to today's internet.
So here are some of DARPA's most incredible research programs, which could change the future of warfare, and might one day have applications that extend far beyond the military.

Disc-Rotor Compound Helicopter

The Disc-Rotor is a collaboration between DARPA and Boeing. Hoping to marry the best features of a helicopter and an airplane, the Disc-Rotor program aims to develop a new type of aircraft capable of a seamlessly transitioning from hovering like a helicopter to flying like a plane.
The design is propelled by rotor blades that extend from a central disc, letting it take off and land like a helicopter. But those blades can also retract into the disc, minimizing drag and letting the Disc-Rotor fly like a plane, powered by engines beneath each wing.

Vulture
DARPA's Vulture program is developing the technology to enable an "airborne payload" to remain in the sky for more than five years at a time, performing intelligence, surveillance and communication missions. In practice, that means developing unmanned aircraft that act like satellites.
Boeing is again working on the project, researching its "SolarEagle," a solar-powered, unmanned craft with a 120-meter wing span. It is designed to operate at altitudes above 18,000 meters. Boeing hopes it will make its first demonstration flight in 2014.

ChemBots
Tech company iRobot worked with DARPA on its "ChemBots" program. The aim was to build soft, flexible robots that could deform their bodies to move through openings smaller than themselves (e.g. under doors) to carry out covert tasks.
IRobot used a transitional -- or "jamming" -- material, with properties of both a solid and a liquid, to create a flexible robot that can crawl on six floppy legs. While DARPA's funding has now expired, iRobot is still researching soft robotics and "jamming" technology.

LANdroids (Local Area Network droids)
DARPA also funded iRobot to research its LANdroids program.
The aim was to give soldiers reliable communications in urban areas by creating pocket-sized robots they could scatter as they moved through an area. The robots would each act as a node in a wireless communications network. As the soldiers move, the robots would autonomously move with them, filling gaps in the network.
According to iRobot, the LANdroid it created weighed around one pound, was highly mobile and used a flipper mechanism for self righting and obstacle climbing.
Following the DARPA research, iRobot has developed a throwable robot for soldiers that will be available from 2012. It says the robot could be used to investigate hard-to-access places such as tunnels and ditches.


Falcon HTV-2
The ultimate goal of the Falcon Hypersonic Technology Vehicle 2 (HTV-2) program is to create a vehicle that can fly anywhere in the world in less than an hour -- while enduring temperatures in excess of 1,925 C (3,500 F).
DARPA has already produced and flown a test HTV-2 -- an unmanned, rocket-launched aircraft that travels at Mach 20 (about 13,000 miles per hour). At that speed a flight between New York City and Los Angeles would take less than 12 minutes.
HTV-2 made its maiden flight in April 2010, but crashed into the Pacific after just nine minutes. A second flight, in August 2011, lasted a similar time before meeting the same end.
Following the second flight HTV-2 program manager Major Chris Schulz said: "We do not yet know how to achieve the desired control during the aerodynamic phase of flight. It's vexing; I'm confident there is a solution. We have to find it."

Phoenix
Communication satellites orbit more than 20,000 miles above the Earth. When they break they usually have to be replaced by launching a new satellite, even though many of these broken satellites still have usable parts, such as antennae and solar arrays.
The Phoenix program is trying to find a way to remove and re-use valuable components from broken or "retired" satellites -- in essence, recycling space junk.
DARPA envisions small "satlets" or "nano satellites" being carried to a broken communication satellite by a "tender" satellite, and then robotically attaching to the broken satellite's antenna.
But before it can become reality they must develop new robotics and remote imaging systems, and design grappling tools to grip, cut, and modify satellite parts.

Transformer
The Transformer program aims to build a flying car for the battlefield. And the car will need to fly itself.
The aim is to create a vertical take-off-and-landing vehicle that can carry four people more than 250 miles on one tank of fuel.
Six contractors are working on the project, including Lockheed Martin, AAI Corp. and Carnegie Mellon University (CMU).
Sanjiv Singh, a CMU research professor of robotics, said: "In practical terms ... the vehicle will need to be able to fly itself, or to fly with only minimal input from the operator. And this means that the vehicle has to be continuously aware of its environment and be able to automatically react in response to what it perceives."

Cognitive Technology Threat Warning System (CT2WS)
The Cognitive Technology Threat Warning System program is developing binoculars that can identify threats from a long distance and then inform a soldier of the danger.
It will use wide-angle optics and digital imaging, but the really clever bit is its use of "cognitive visual processing algorithms" and "operator neural signature detection processing." That means monitoring the subconscious patterns in a soldier's brain to detect a threat the soldier has perceived before they are even consciously aware of it.

INDIA SUCCESSFULLY LAUNCHES AGNI-IV MISSILE





DRDO Statement: India today successfully test fired its most advanced long range missile system, the Agni-IV. The missile was launched from a road mobile launcher at 9AM from Wheelers’ Island off the coast of Odisha. The missile followed its trajectory, attained a height of about 900-km (??) and reached the pre-designated target in international waters of the Bay of Bengal. All mission objectives were fully met. All systems functioned perfectly till the end encountering re-entry temperatures of more than 3000⁰C.

This missile is one of its kind, proving many new technologies for the first time, and represents a quantum leap in terms of missile technology. The missile is lighter in weight and has two stages of solid propulsion and a payload with re-entry heat shield. The composite rocket motor which has been used for the first time performed flawlessly. The missile system is equipped with modern and compact avionics with redundancy to provide a high level of reliability. The indigenous Ring Laser Gyros based high accuracy INS (RINS) and micro-navigation system (MINGS) complementing each other in redundant mode have been successfully flown in guidance mode for the first time. The high performance onboard computer with distributed avionics architecture, high speed reliable communication bus and a full Digital Control System controlled and guided the Agni-IV to the target. The missile has reached the target with very high level of accuracy. Radars and electro-optical systems along the coast of Odisha tracked and monitored all parameters of the missile test. Two Indian Naval ships located near the target witnessed and recorded the final event.

Defence Minister A.K. Antony congratulated the DRDO team on its achievement. Avinash Chander, Distinguished Scientist & Chief Controller (Missiles & Strategic Systems) at DRDO and Programme Director, AGNI addressed his team after the launch, and called today's test the beginning of "a new era in modern Long Range Navigation Systems". He said, “this test has paved the way ahead for the success of AGNI-5 Mission, which will be launched shortly."

Agni-IV Project Director Ms Tessy Thomas and her team prepared and integrated the missile system and launched the Agni-IV successfully today. An ecstatic Ms Thomas said today that the DRDO had produced and proven many new state of the art technologies with the Agni-IV like composite rocket motors, very high accuracy Ring Laser Gyro based Inertial Navigation System, Micro Navigation System, Digital Controller System and very powerful onboard computer system. The Agni-IV can deliver strategic warheads, and will be produced in large numbers for delivery to India's nuclear command.

Two more Zumwalt class destroyers for US navy



The U. S. Navy has awarded General Dynamics Bath Iron Works, a subsidiary of General Dynamics, a $1.8 billion contract for the construction of DDG 1001 and DDG 1002, the next two ships in the Zumwalt-class program. DDG 1001 is scheduled to be delivered in December 2015 and DDG 1002 is scheduled to be delivered in February 2018.

"This contract enables us to maintain a strong base of quality shipbuilding jobs in Maine and continue our contributions to sustaining the U.S. Navy fleet," said Jeff Geiger, president of Bath Iron Works. "It provides Bath Iron Works with a healthy backlog of work and reflects the Navy's continued commitment to the DDG-1000 program, as well as their confidence in our ability to build and deliver all three ships of this class." 


Geiger said, "Winning this work is a result of our commitment to operational excellence and to finding more efficient, affordable ways to operate in every part of our business. It gives us the opportunity to continue introducing new and innovative ways to build capable ships for the Navy." 


"We appreciate all the support the Maine Congressional delegation has provided to this program. Their commitment to national defense and their advocacy on behalf of the workers of Maine has been a crucial factor," Geiger said.

China launches Tiangong-1 space module






What is China's Tiangong 1?
The Tiangong 1 module is China's first spacecraft designed for orbital docking tests and space research. It's name translates to "Heavenly Palace" in English. The module is a prototype for a planned space station, which China plans to build in orbit as part of its human spaceflight program. China's plan currently is to build a 60-ton space station by 2020. [Gallery: Tiangong 1, China's First Space Laboratory]
Why is the Tiangong 1 mission important for China?
China has been taking a stepping stone approach to human spaceflight that began with the 2003 launch of Yang Liwei, China's first astronaut. In 2005, China launched its second human spaceflight, a two-person mission, in 2005. A three-person flight followed in 2008, a mission that included China's first spacewalk.
The Tiangong 1 mission will mark China's first attempt to dock two spacecraft together, a vital skill that will be needed to build a large space station in orbit.

How large is the Tiangong 1 space lab?
Tiangong 1 is a cylindrical spacecraft that is about 34 feet (10.4 meters) long and 11 feet (3.4 m) wide. The space laboratory weighs about 8.5 metric tons, or about 9.4 short tons (U.S.).
The Chinese space station prototype consists of two major segments: the experiment module and a resource module.
The experiment module is the primary work and living area for visiting astronauts. It is powered by two solar arrays and serves as the docking point for arriving Shenzhou spacecraft. According to a mission overview video, the laboratory can be left unmanned or host visiting crews of up to three astronauts.
The solar arrays are attached to the Tiangong 1 resource module, which also contains the propellant tanks and rocket engines for the spacecraft.

How will China launch Tiangong 1?
China will use a special version of its Long March 2F rocket to launch the space laboratory. The rocket, called a Long March 2F T1, is a modified version of the booster China uses to launch its crewed Shenzhou spacecraft. It does not have a launch escape system (since Tiangong 1 is launching unmanned) and includes a custom fairing and an improved rocket booster structure in order to increase its lift capacity, Chinese space officials said.
The Long March 2F T1 rocket is about 170 feet (52 meters) tall and can launch payloads of up to 8.6 metric tons into space. It weighs about 493 metric tons at liftoff. It will launch from the Jiuquan Satellite Launch Center in Northwest China.
When will the first docking at Tiangong 1 occur?
China currently plans to launch its first Shenzhou spacecraft to Tiangong 1 in early November. That mission, Shenzhou 8, will be unmanned. The mission is expected to last at least 12 days and include two docking demonstrations. [Infographic: How China's First Space Station Will Work]
 If that first mission is successful, at least two more flights (Shenzhou 9 and Shenzhou 10) are planned in 2012. The Shenzhou 10 mission may carry the first crew to the Tiangong 1, and may include China's first female astronaut, according to state media reports.

How high will the Tiangong 1 fly?
The Tiangong 1 module will initially launch into a 217-mile (350-kilometer) orbit around Earth, which will require two maneuvers by the spacecraft after liftoff in order to reach the planned flight path. While in this orbit, the spacecraft will be put through several systems tests.
If all goes well, the Tiangong 1 will be lowered to an orbit of about 213 miles (343 km) in order to meet the Shenzhou 8 spacecraft in November. At the end of that mission, the space lab will return to the higher orbit to await the next visiting Shenzhou spacecraft.
Where is the Tiangong 1 space laboratory controlled from?
The Tiangong 1 mission will be controlled by flight controllers at the Beijing Aerospace Flight Control Center, the Mission Control for China's human spaceflight program.

How long can the Tiangong 1 spacecraft stay in space?
Currently, China plans to keep the Tiangong 1 module in orbit for about two years, after which the spacecraft will be commanded to destroy itself by burning up in Earth's atmosphere, according to a mission profile video.

India conducts successful trial of AGNI II missile





India's Agni-II was launched successfully today at 9:30AM from the Eastern seaboard. According to a DRDO statement, "The successful launch once again proved reliability of the medium range surface to surface missile." The 2000-km range surface to surface missile, already inducted and part of countries arsenal for strategic deterrence, was launched as a training exercise by the country's nuclear command. The missile reached an apogee (peak altitude) of 220-km and hit the target. All the radar, telemetry systems, ectopic system tracked & monitored all parameters throughout the trajectory. Two ships located near the target point have tracked the missile in the final stage.
