Chinese Ski Jump Spotted

August 12, 2009: The wonders of digital photography (on the ground and from commercial satellites) provide evidence that China is testing the use of its Su-30 aircraft and a ski ramp type carrier deck design. China is expected to have an operational carrier soon, and it will be one using a ski ramp (instead of a steam catapult). It was suspected that there was a ski ramp training facility somewhere, now it's been located, in Xian-Yanliang. What's strange about this is the altitude of this airbase; nearly 500 meters (rather than sea level.) Then again, Xian-Yanliang is a windy place, which allows testing of the stationary ski ramp built there, with winds typical of what would be encountered when the carrier turned into the wind for the commencement of aircraft launching operations.

Late last year, China announced that its first class of carrier aviators had begun training at the Dalian Naval Academy. The naval officers will undergo a four year course of instruction to turn them into fighter pilots capable of operating off a carrier. The Russians have warned China that it may take them a decade or more to develop the knowledge and skills needed to efficiently run an aircraft carrier. The Chinese are game, and are slogging forward.

Earlier this year, the Russian aircraft carrier Varyag was renamed the Shi Lang (after the Chinese general who took possession of Taiwan in 1681, the first time China ever paid any attention to the island) and given the pennant number 83. The Chinese have been refurbishing the Varyag, one of the Kuznetsov class that Russia began building in the 1980s, for several years now. It is expected to be ready for sea trials by the end of the year.

The Varyag has been tied up in a Chinese shipyard at Dailan since 2002. While the ship is under guard, it can be seen from a nearby highway. From that vantage point, local military and naval buffs have noted that some kind of work is being done on the ship. The only visible signs of this work are a new paint job (in the gray shade used by the Chinese navy) and ongoing work on the superstructure (particularly the tall island on the flight deck.) Many workers can be seen on the ship, and material is seen going into (new stuff) and out of (old stuff) the ship. The new contracts are believed to be for more equipment for the Varyag, in addition to the non-custom stuff already going into the ship.

Originally the Kuznetsovs were conceived of as 90,000 ton, nuclear powered ships, similar to American carriers (complete with steam catapults). Instead, because of the cost, and the complexity of modern (American style) carriers, the Russians were forced to scale back their goals, and ended up with the 65,000 ton (full load ) ships that lacked steam catapults, and used a ski jump type flight deck instead. Nuclear power was dropped, but the Kuznetsov class was still a formidable design. The thousand foot long carrier normally carries a dozen navalized Su-27s (called Su-33s), 14 Ka-27PL anti-submarine helicopters, two electronic warfare helicopters and two search and rescue helicopters. But the ship can carry up to 36 Su-33s and sixteen helicopters. The ship carries 2,500 tons of aviation fuel, allowing it to generate 500-1,000 aircraft and helicopter sorties. Crew size is 2,500 (or 3,000 with a full aircraft load.) Only two ships of this class exist; the original Kuznetsov, which is in Russian service, and the Varyag. Currently, the Kuznetsov is operating in the Mediterranean.

The Chinese have been in touch with Russian naval construction firms, and may have purchased plans and technology for equipment installed in the Kuznetsov. Some Chinese leaders have quipped about having a carrier by 2010 (this would have to be a refurbished Varyag). Even that would be an ambitious schedule, and the Chinese have been burned before when they tried to build new military technology in a hurry.

U.S. Sentences Three for Military Tech Leaks to China

U.S. Sentences Three for Military Tech Leaks to China

The U.S. has sentenced three Chinese men to federal prison for attempting to export technology with potential military applications to China, the U.S. Department of Justice said Tuesday.

In separate cases, two of the men were charged with attempting to export thermal-imaging cameras, and a third was charged with illegally exporting hundreds of integrated circuits that could be used in military radar systems, the department said in a statement.

The men, all from Beijing, were given prison terms of between 20 months and five years in rulings handed down starting last week. Their exports to China were illegal without clearance from the U.S. Department of Commerce because the items have both military and non-military uses, the statement said.

In the case of the integrated circuits, prosecutors argued that the defendant was using a front company in the U.S. to ship items to his company in Beijing, it said. A catalog from the man's Beijing company was found to carry pictures of military craft and state a goal of helping "facilitate the building of the national defense of China," the statement said, citing the sentencing brief.

Prosecutors also argued that the man supplied restricted U.S. technology to several Chinese customers, including one linked to a state-owned company that makes missile systems and spacecraft.

The two men in the thermal cameras case were arrested at the Los Angeles airport last year after 10 of the cameras were found in their luggage, either stuffed in their shoes or hidden in their packed clothes. The cameras are contained in two-inch cubes and are sensitive enough to detect heat on an object too small to be seen by the naked eye, the statement said.

The U.S. has imprisoned and fined multiple Chinese nationals over military technology exports to China in recent years. Defendants in those cases have attempted to export technology including fighter jet components and night vision equipment.

Ukraine military hovercraft to equip Chinese navy

Ukraine military hovercraft to equip Chinese navy

Kiev - China's navy is to purchase four Ukrainian military hovercraft in a 315-million-dollar deal potentially shifting the South China Sea naval balance, the Interfax news agency reported. A shipbuilding firm in Ukraine's Black Sea port Feodosia will construct two Zubr (translation - Bison) class craft, and a second pair of vessels will be built in China under the supervision of Ukrainian technicians.

A Ukrainian government publication listing state contracts confirmed the order without giving its value. Officials at the Morye shipyard in Feodosia declined comment.

The Zubr hovercraft is designed to carry three tanks, 10 armoured personnel carriers, or as many as 500 troops at speeds exceeding 63 knots.

The vessel can due to its larger size operate in rougher seas than smaller hovercraft.

The Russian, Ukrainian, and Greek navies currently operate the Zubr, with a total ten hovercraft produced since 1988.

China's navy currently lacks heavy capacity hovercraft of the Zubr type. The most modern Chinese naval hovercraft in operation, the Jingsah II, has a maximum capacity of 70 troops.

The Zubr hovercraft's capacity to deliver substantial combat forces by water at speeds doubling conventional landing ships would, once in Chinese inventory, complicate defence planning for South China Sea nations particularly Taiwan, according to the report.

Feodosia's Morye shipyard as co-developer of the Zubr hovercraft with St. Peterburg's Almaz naval design bureau technically is banned from selling Zubr's military technologies to a third party, without Almaz management agreement.

China in 2006 was in talks with Almaz on the purchase of six Zubr hovercraft without result.

Management at Ukraine's Morye shipyard, actual production of site of all Zubr-class hovercraft, began talks with Chinese naval representatives in 2008, a naval source told Interfax.
