China developing new type of destroyer with superior stealth: media



China is developing a new type of guided-missile destroyer that is larger and stealthier than its present destroyers, an influential China newspaper said Friday.

The China Youth Daily said the new destroyer, believed to refer to 052D vessels now in construction, are the next generation of the 052C destroyers China's Navy currently operates.

The newspaper said the new type of destroyer has maintained an emphasis on seaworthiness and durability but has also been designed for greater stealth.

In addition, it has an improved active phased array radar (APAR) , which is believed to be developed from earlier radar systems mounted on 052C destroyers, and a new vertical launching system that can support different types of missile systems.

Some people have described the O52C as the "Chinese Aegis," comparing it to the United States Navy's Aegis-equipped destroyers.

U.S. media reported earlier this month that China recently unveiled its first group of 052D destroyers with a displacement of 6,000 tons, marking a new stage in the Chinese Navy's long-term experimentation with different destroyers.

Reports also said that if China has between 10 and 15 052D destroyers into the battleground, it will become the second largest combat force on sea in the Asia Pacific region after the U.S. Navy.

India commits $6 bn for developing stealth jet with Russia



India has committed an initial $6 billion for jointly developing a fifth-generation stealth combat jet with Russia, a project that will eventually cost the country $30 billion and envisages the manufacture of 144 aircraft.

All these aircraft would be single seaters, the same which the Russian Air Force will have, but some components like onboard computers and systems would be different as in the case of the Sukhoi SU-30MKIs.

Now designated PMF, or Perspective Multirole Fighter, by Russia, the Indian aircraft would be made in India, Browne said, adding that discussions with the Russian government are already on.

India and Russia had signed an agreement in this regard Dec 21, 2011, to set up a 50:50 joint venture on the lines of BrahMos Aerospace and share development work.

India's Hindustan Aeronautics Limited (HAL), aided by the Defence Research and Development Organisation (DRDO) will partner Russia's United Aircraft Corporation (UAC) - which will provide the super cruise engines and certain stealth technologies - in the project.

Indian scientists are keen to pool in the R&D effort, and the agreement calls for joint development, particularly in design, guidance systems and onboard software. That means India will also have a proprietary share on Intellectual Property Rights (IPR).

The exact costing is yet to be worked out but, inclusive of the development costs, the figure could be around $30 billion, according to HAL sources.

Notably, a figure of 200-plus of two-seater version for India was considered earlier with possible induction from 2017 with an initial lot from Russia. Development in that time frame however is not happening.

To cut down on the development costs and the timelines, the IAF has plans to begin their induction from 2020 onwards, Air Chief Marshal Browne said.

Discussions with Russia are on to sign the first R&D phase, and the first prototype is likely to be delivered to India in 2014, followed by two more in 2017 and 2019. The series production "will only be ordered based on the final configuration and performance of the third prototype".

The air chief observed that speed, reach and precision are the keywords for the IAF's transformation that is now on.

He noted that various acquisition programmes of the IAF were going on as normal and so were the upgrade programmes. The IAF had already spent around Rs. $30 billion in the last five years and that there was adequate budgetry support to execute its transformation programmes by 2027, when all the 42 combat squadrons sanctioned by the government will be operational.

He reiterated that he expected the deal for 126 French Rafale medium multi-role combat aircraft (MRCA) to be finalised by March 2013. There are virtually daily meetings between the aircraft partners, Dassault, Thales and engine maker Snecma on the one side and IAF, HAL and defence ministry representatives on the other.

On the legacy aircraft, he said that while the Soviet-vintage IL-76 and AN-32 transport aircraft were already under upgrades to give them an extended life of 10 to 15 years, the tender to upgrade the IAF's 100-odd Jaguar aircraft with new engines was about to be issued - likely by October-end - to Honeywell of the US.

IAF tenders for combat and heavy-lift helicopters and midair refuellers have already been opened over three weeks beginning mid-September. While the combat helicopter deal has gone to Boeing for its Apache AH-64D because Russia withdrew its Mi-28 helicopter, the winner of the other two would be decided on the basis of lifecycle costs. Calculations were being done now, and it should take a couple of months in each case to declare the winner.

Notably, all the aircraft deals with the Soviet Union/ Russia so far have been on a government-to-government basis, including for the new fifth-generation fighter aircraft (FGFA). This is the first time that Russian aircraft - Mi-26 heavy-lift vs Boeing CH 47F Chinook, and the Il-78 against the Airbus MRTT - are pitted in global competitions in India, involving mandatory offsets. If the Russians win, they will have to do what is required by the DPP (Defence Procurement Procedure) and invest 30 percent of the deal back in the Indian defence industry.

The (FGFA) programme began in 2006 and this, as also the deal for the Indian Navy's 45 MiG-29 shipboard fighters, is exempt from offsets. The MiG-29 programme is part of the INS Vikramaditya (Admiral Gorshkov) aircraft carrier's acquisition programme, signed well before the DPP came into place.

Original Stealth Ship Sold for Scrap


Once-classified Navy stealth ship 'Sea Shadow' has been sold to an Alameda shipyard for scrapping

The $2.5 million bid from Bay Ship & Yacht Co. won the federal government auction. The firm was interested not so much in the space-age stealth ship but the barge that houses it, which will be converted into a drydock, reports 'The Sacramento Bee'.

Sea Shadow was built in 1985 by Lockheed Martin in Redwood City, under contract with the U.S. Navy, for a price of $50 million. The goal was to test whether radar-evading technology proven in fighter aircraft could also be applied to ships.

The experiment was a success. Sea Shadow proved in exercises that it could sneak up on aircraft carriers undetected.

After trying unsuccessfully to give Sea Shadow away to a museum, the Navy decided earlier this year to sell it for its scrap value alone. It was offered with a unique submersible barge, known as HMB-1, which was originally built for a CIA mission in 1974 to retrieve a sunken Russian submarine from the floor of the Pacific Ocean and later became Sea Shadow's garage.

Stealth: Not-So-Secret Secrets

If major international war really is obsolete, it is mainly due to America's military superiority: it makes adversaries reluctant to take us on.

We are now seeing Russian and Chinese "stealth" aircraft appear, at least in prototype form. The Chinese have prototypes of the J-20 large fighter bomber, which looks as if it may enter service with the Chinese Air Force in 2018. In a recently published report on Chinese military power, the US Department of Defense wrote that the J-20 shows "China's ambition to produce a fighter aircraft that incorporates stealth attributes, advanced avionics and supercruise capable engines." Supercruise in this context means that the aircraft can fly at supersonic speeds for sustained periods of time. This has only been achieved by the now grounded US SR-71 Blackbird reconnaissance jet and the F-22.

Americans should get used to the idea that today's military technological breakthrough will be commonplace on tomorrow's battlefield. It costs a lot to develop and build the best military in the world.

If the pundits are right, and if major international war really is obsolete, it is largely due to America's overwhelming military superiority: it makes adversaries reluctant to take us on. Maintaining this U.S. superiority is what keeps the world more or less at peace.

Russia, meanwhile, is working on the Sukhoi T-80, also known as the PAK-FA -- a supposedly stealthy version of the SU-27 family of fighter bombers. The Russians have negotiated a co-development deal for this aircraft with India, which plans to buy around 200 copies.

Sukhoi has three T-80 test aircraft in operation, and hopes to have 11 more test aircraft flying before the first production model is delivered in 2013. The Russian air force is planning to have the T-80 in service sometime in 2015 or 2016, but its arrival in the Russian Air Force will probably be delayed. How effective the T-80 will be is open to question. Russia has developed some excellent combat airplanes over the years, but it has also built large numbers of fighters that have proven to be less than reliable, such as the 1970s' MiG 23.

Meanwhile, the US F-35 Joint Strike Fighter program, which originated in 1993, grinds ahead. It has already cost US taxpayers more than $400 billion. By the time the last F-35 leaves the production line sometime in the 2030s, the whole program will have cost more than one-and-a-half trillion dollars.

The F-35 was supposed to be the final manned fighter airplane built by the US; after that, all combat flying would be done by drones -- but things may not turn out that way. The US Navy has started preliminary work on a new manned fighter attack aircraft called the FA-XX.

The F-35 was also supposed to be a fine example of multinational cooperation. Certainly the US's European partners, including the British, the Dutch, the Norwegians, the Italians and the Danes, all had memories of successful collaboration with the US Defense Department on projects in the past. America's foreign partners are already suffering from "sticker shock," but as they have already invested considerable sums in the program, probably few of these partners will choose to walk away.

Any real stealth secrets inherent in the F-35 will almost certainly leak out through these foreign partners. They may have already leaked. However since the classified technology dates from the mid-1990s, it can hardly be considered truly "cutting edge."

Many Americans believe that Stealth technology is still an exclusive US military advantage and that the "Secrets of Stealth" must be preserved at all costs. Stealth, or as it is sometimes called, Low Observable Technology, has acquired an almost mythical significance. This myth tends to blind both political leaders in Washington and many media commentators to the true value of what is misleadingly referred to as invisibility. During the 1980 Presidential campaign, the Carter administration announced that it was working on an invisible bomber, which turned out to be the very expensive B-2 bomber, of which the US Air Force managed to buy a grand total of 21.

In the late 1970s, the US Air Force was working on a smaller Stealth aircraft, the F-117 Nighthawk, which secretly entered into service in 1982. Publicly unveiled in 1989, the US Air Force hailed it as a giant breakthrough in its military technology. That was nearly quarter of a century ago, it is hard to see why anyone expects that the secrets of stealth are still secret.

The US had been working on radar-evading and heat-signature-suppressing technologies since the late 1950s. There is nothing either very secret or surprising about this. All military forces try to hide their forces and are willing to spend a lot of money and effort on various forms of camouflage and concealment.

Stealth technology as we know it came into being in the 1970s, thanks in part to work by a Russian mathematician, but mostly thanks to advances in US computer technology. Lockheed was able to build a technology demonstration aircraft for the air force called the "Have Blue," which showed that an aircraft with the new radar-evading technology could penetrate Soviet-style 1970s integrated air defense systems.

"Have Blue" was followed in the early 1980s by the secret F-117 Stealth "Fighter," which was never actually a fighter but, as it was roughly the size of a fighter, the Air Force choose to call it a fighter, even though it would have been more accurate to call it a light reconnaissance bomber.

Although the F-117 was first used during the overthrow of the Panamanian dictator Manuel Noriega in 1989, it proved itself during the 1991 Gulf War. The Iraq air defense system, which at the time was the best that Saddam's oil wealth could buy, was unable to shoot down a single F-117, even though they flew dozens of missions over the most heavily defended parts of Iraq, especially over Baghdad. The F-117s were able repeatedly to hit Iraqi headquarters and other critical targets such as bridges and industrial facilities. It was this that crippled Saddam's ability to continue the war.

At the same time in the early 1990s, the Air Force was introducing its new strategic bomber, the B-2. This was, and is, an extraordinary aircraft that combines stealth with a long range. The B-2 can fly more than 5000 miles on a single fuel load, as well as anywhere in the world with air-to-air refueling, even with a heavy payload. This bomber was first used against targets in Afghanistan in the fall of 2001.

Since its existence was revealed during the 1980 Presidential campaign, "stealth" has become surrounded by an aura of mystery and invincibility that tends to obscure its value in being able to defeat the most advanced air defense systems. Although talk about invisible and invulnerable airplanes was hogwash, normally skeptical journalists and media commentators bought into the myth, and sometimes used it to propagate a dangerously sterile vision of modern war, especially the idea that wars can be fought with no friendly casualties and almost no casualties on the enemies' side.

In 1999, during the Kosovo operation, an F-117 was shot down over Serbia by an old Soviet SA-3 surface-to-air missile. This seems to have been done by a Serb missile battalion commander who, using basic intelligence methods, analyzed US air operations. Specifically, Serbian intelligence had informers with cell phones around US bases; the informers would phone in the departure times of US aircraft. Using this data the Serbs were able to make educated guesses when and where US aircraft would appear in the skies over their missile launchers.

The pilot ejected and was rescued, but the wreckage of the plane was recovered by the Serbs; it is believed they gave the debris to Russia as a "thank you" for Moscow's political support.

Whatever the next military technological breakthrough is, if it keeps American troops alive and victorious in war and globally respected in peacetime, it will be worth every penny.

Fourth T-50 Stealth Fighter to Fly This Year


Russia's United Aircraft Corporation (UAC) is to introduce a fourth Sukhoi T-50 stealth fighter into its test and development program this year, the company's President Mikhail Pogosyan said on Thursday.

"We are now testing three aircraft. A fourth will be brought in this year," he said.

Pogosyan had said earlier this year that the firm would introduce a fourth aircraft into the test program but did not disclose when.

The first production standard T-50 is due to enter service with the Russian Air Force by 2015, and the first evaluation example by 2013. The service plans to acquire 60 of the fifth-generation fighters.

The T-50, also known as project PAK-FA, first flew on January 29, 2011 and was first publicly revealed at the Moscow Air Show in August that year. India will also acquire an advanced fighter aircraft based on the T-50.
