Bombarderos chinos estarán dotados de motores rusos.

La Asociación rusa de Investigaciones Científicas y Producción Saturn, ha anunciado la entrega al cliente chino de la primera partida de doce motores D-30KP-2, tal como lo contempla el contrato firmado el año pasado. La magnitud de las compras de motores por China certifica que este país probablemente desarrolle un programa de construcción de varias decenas de bombarderos portamisiles en el curso de los próximos años, estima el experto del Centro de Análisis de Estrategias y Tecnologías, Vasili Kashin. No sorprende la propia cooperación de China con los fabricantes rusos de motores, sino sus proporciones. Los suministros de los ciento ochenta y cuatro motores previstos por el contrato deberán concluir en 2015. Además, se sabe que en 2009 China cerró otro contrato de compra de otros cincuenta y cinco motores D-30KP-2, que ya fue cumplido.

De tal manera, de 2009 a 2011 China firmó contratos para la adquisición como mínimo de doscientos treinta y nueve motores. El motor D-30KP-2 es utilizado por los aviones pesados de transporte Il-76 y sus diferentes modificaciones, incluido el avión radar chino de detección lejana KJ-2000. Incluso teniendo en cuenta las compras efectuadas últimamente por la Fuerza Aérea china de aviones Il-76 de segunda mano, el total de tales aviones en China apenas supera una treintena. Es muy poco probable que la Fuerza Aérea china haya decidido reequipar de una vez su parque de Il-76 con nuevos motores. Por lo tanto, los motores se compran fundamentalmente para otros aviones. En primer lugar, puede ser el avión de transporte militar Y-20, que está siendo creado con asistencia de la empresa ucraniana de construcciones aeronáuticas Antónov. Previamente los medios chinos informaron de que el primer vuelo del avión puede hacerse efectivo antes de fin de 2012. Incluso de ser así, las pruebas del avión llevarán años.

Bombardero H-6K

Al propio tiempo, se construirán solo contados modelos experimentales. Según algunas publicaciones chinas, ya ahora existen dos modelos experimentales Y-20, ensamblados a lo largo del año en curso. Pero este avión no cuadra con el papel de gran consumidor de motores rusos. Vasili Kashin supone que es muy probable que este papel le pertenezca a un avión chino más grande, cuya producción se inició en la segunda mitad de los años 2000. —Se trata del bombardero H-6K. En este aparato, a diferencias de las modificaciones anteriores del avión H-6, los dos viejos motores chinos WP-8 han sido sustituidos por los más modernos D-30KP-2 para aumentar la autonomía de vuelo de estas máquinas. H-6K es un nuevo término en el desarrollo de los aviones bombarderos chinos. Dicha nave está dotada de un potente equipo radioelectrónico, los tripulantes tienen en la cabina display multifuncionales. Lo que también es importante, cada avión puede ahora llevar seis misiles alados de más de dos mil kilómetros de alcance. Merced al incremento de la autonomía de vuelo el avión puede atacar cualquier punto del sur del Pacífico.

A la vez, para abatir los objetivos no tiene necesidad de entrar en la zona de operación de la defensa antiaérea del enemigo. Para igualarse en lo referente a las posibilidades principales con los bombarderos estratégicos de EEUU y Rusia, al H-6K le queda cumplir otra importante condición: tener la posibilidad de repostar combustible en vuelo. Actualmente, China no cuenta con un aparato de reabastecimiento en vuelo lo suficientemente potente para un avión tan grande y por eso China evidenció interés por los aparatos rusos Il-78. Las proporciones de las compras chinas de motores prueban que ese país cumple un programa de construcción de no menos de sesenta nuevos bombarderos portamisiles en el curso de los próximos años. Como resultado el parque de bombarderos chinos se renovará considerablemente y será un nuevo factor importante de mantenimiento del equilibrio de fuerzas en la región Asia-Pacífico, supone Vasili Kashin.

H-6K Air Striking Platform


Apparently abandoning efforts to develop an entirely new bomber aircraft, China has resumed production of the venerable H-6 bomber to satisfy PLA Air Force requirements for long range strategic strike. Production of the H-6 had halted in the early 1990s, but resumed around the year 2006. One could equate the Xi'an H-6 to the American B�47 in terms of capability with air-to-surface missiles, electronic countermeasures, and a combat radius of more than 1,000 miles. Although based on a half century old design, the H-6K is still a remarkable platform for its multi-performance in modern warfare when PLA has added new technologies onto it.

This variant is called the H-6K, the letter "K" representing the "Air Striking Platform" (Chinese Pinyin: Kongzhong-daji-pingtai). Compared with earlier variants of the H-6 bomber, the new H-6K features enlarged air inlets for a new and more powerful engine, a new ground search radar in its redesigned nose radome, a thermal/TV imager turret, data link and electronic warfare gears. Other distinguishing improvements include six underwing hardpoints [versus four in earlier versions], and a completely enclosed tail secion.

In September 2008, a screenshot of XAC (Xi'an Aircraft Corporation) internal CATV news showed that China was producing a new variant of H-6 bomber family. The photos of a new type of bomber were first uploaded onto cjdby.net, showing the planes painted with the serial numbers of China's Air Force. The photos triggered a new round of discussions of the growing strike capability of China's air force. "It signifies the plane as the keystone of a strategic ground attack force of the Chinese air fleet and enhances China's air strike ability," Daniel Tong, founder of the website Chinese Military Aviation, told the Global Times. Frequent sightings of new prototypes of aircraft and test flights show China is reinforcing its air force by developing more airborne weapons, Tong said.

The official Chinese news release following the successful flight tests of the H-6K indicate the Chinese military has high expectations for this bomber. The news release described its test flight as an event that "20,000 Xian Aircraft Company staff have been longing for, for 13 long years." Guests invited to observe the maiden flight of the bomber included top leaders from the Central Military Commission and the Commission of Science, Technology and Industry for National Defense.

Carrying capacity is a measure of a bomber's combat potential. The early model H-6 had a typical payload weight of 9 tons, while the H-6K carrying capacity has increased to 12 tons. The new H-6K may carry China's new long-range CJ-10 / DH-10 land-attack cruise missile, comparable to the United States "Tomahawk" cruise missile design. The total weight of the 6 CJ-10 / DH-10 missiles would be 10,200 kg, suggesting why China upgraded the H-6H to the H-6K. With imported Russian D-30 engines, H-6K can patrol in the air defense circle in China's inner mainland for a longer time and use long-range cruise missile to attack US bases located in Guam. When used for conventional precision offensive operations, the Chinese KH-55 fired from Chinese air space will put the entire Korean peninsula within strike range, and also much of Japan, including the whole of Okinawa, parts of Honshu island and all of Kyushu and Shikoku.

The H-6K might also have the ability to fire YJ-12 anti-ship missile at stand-off ranges to attack US aircraft carrier groups in the West Pacific. Or the H-6K might carry 6 ultra-long-range Air-to-Air missiles to hunt US, Japanese or South Korean Airborne Early Warning systems, like E-2 and E-3. Possibly the H-6K could use its bomb capacity to carry PLA's air launched torpedo for destroying underwater submarines in Chinese East Sea and South Sea areas. The H-6K might share target data with PLA Navy's Ka-28 and Z-9 helicopters in fleet anti-submarine warfare.

The H-6K has a re-designed nose in which the standard glassed-in nose is replaced by a lightning-proof radar radome so. Inside the radome, H-6K is equipped with a powerful PD radar, which integrates navigation, terrain following and missile aiming. The H-6K also has an upgraded glass cockpit and incorporates a more advanced avionics integrated with power, flight and fire control.

Behind the H-6K's cockpit, XAC installed 2-3 blade antennas, which are probably parts for datalink system for guiding long-range missiles. Via Datalink, H-6K could receive object information from KJ-2000 AWACS and silently fire AA missiles to attack Airborne Early-Warning Systems. Some speculate this may be the Air-to-Air missile sometimes called a "ShaShoujian" (Assassin's Mace) weapon. The Chinese term Sha Shou Jian (literally "killing hand club"), a pair of short wood or metal rods used as a martial arts weapon. In general, Sha Shou Jian a popular expression used by sports commentators, businessmen and others in all walks of life to refers to a means or way to overcome a seemingly insurmountable obstacles, a decisive, winning quality.

The H-6K also has an Electro-optical tracking pod that replaces the standard cylindrical radome under the nose. The new device is some type of forward looking infrared [FLIR] system for navigation, target recognition and weapons guidance. It may perform a function similar to the Low Altitude Navigation and Targeting Infrared for Night, or LANTIRN, the system used on the US Air Force's premier fighter aircraft -- the F-15E Strike Eagle and F-16C/D Fighting Falcon. LANTIRN significantly increases the combat effectiveness of these aircraft, allowing them to fly at low altitudes, at night and under-the-weather to attack ground targets with a variety of precision-guided and unguided weapons.

In addition, the two-person flight crew are equipped with ejection seats. An overall redesign of the wings includes an increase in the wingspan and modified wing tip shape, and the hardpoints fitted on it are also newly designed. The rear extension of the engine compartment is widened. It is estimated that there was an increase in the proportion of lighter, stronger titanium alloys or composite. The internal equipment is Chinese-made avionics systems. The tail of the aircraft's original 23 mm cannon was replaced by an electronic warfare system.

Fitted with D-30-P2 turbofan engines of greater thrust and lower fuel consumption than the original WP-8 turbojet engine, the new H-6K has a greatly increased range and combat payload. The two engines, each with a thrust power of 12,000 kilograms, may enhance the H-6K's payload capacity to around 12 tons, enabling it to carry six large long-range cruise missiles. This latest model of H-6 family switched to the more powerful of Russian-made D-30KP2 Aero Engine. According to sources, XAC produced 2 H-6K for PLA's evaluation and testing. Since the design modification is dependent on an imported power plant, the production was initially at a very low rate of 2-3 H-6K in one year.
On 23 July 2010 Russian media reported that China would be provided with 32 D30-KP-2 aero-engines for the H-6K bombers. Because the D30-KP-2 engine delivery had been delayed, the full production of the H-6K had been delayed from 2007. The delivery of the 32 new engines would allow the H6K production line in China to restart. According to these reports, at least 16 D30-KP-2 engines would be used to assemble 8 H-6K bombers, and the rest will act as a store of spare parts. Although the supply contract between China and Russia for the Il-76 transport aircraft did not become effective, Russia intended to fulfill within the main framework agreement the supplement contract of supply of the D30-KP2 engine to China. According to the related agreement, these engines were originally to be used in the Chinese Il-76 transport aircraft's backups. But the Chinese side actually prepared it to change them for the domestically produced new bomber aircraft production.

The final fifth batch of the D-30KP-2 engines manufactured by Research and Production Association Saturn was delivered to the Chinese customer on 23 March 2011. The batch is comprised of 11 engines manufactured under an agreement between Russian State Intermediary Agency for Export and Import of Military and Dual-Purpose Products, Technologies and Services (Rosoboronexport) and People's Republic of China becoming effective in April 2009. The agreement provided for supply of 55 engines until 2012. The final batch of D-30KP-2 engines was scheduled for delivery before the end of March 2011. The agreement also provided for technical support by the manufacturer during the warranty period.

The previous four batches of D-30KP-2 were delivered by the Russian side in November 2009, March, May and October 2010, respectively. The Chinese delegation and the representative of the Chinese Embassy in Moscow Zheng Kai were satisfied with early and high-quality performance by Saturn of its obligations under the agreement. According to Sergei Popov, commercial director at OAO NPO (Research and Production Association) Saturn, "NPO Saturn, which has longstanding friendly relations with the Chinese customer, takes pride in effective completion of this agreement. We look forward to continuing Russian-Chinese cooperation, in particular, supplying D-30KP-2 engines to China."
