RAAF fighters could be outgunned: expert
March 27, 2008 - 5:04PM
RAAF fighters of the future could be outgunned by new Russian-built aircraft which carry far more missiles and fire them in salvos to make a hit more likely, an air power expert believes.
Dr Carlo Kopp, head analyst with the defence think tank Air Power Australia, said the side that could fire the most missiles stood the better chance of winning in this type of beyond visual range (BVR) combat.
Dr Kopp said the most optimistic scenario for the RAAF showed it losing one Super Hornet or one Lockheed F-35 Joint Strike Fighter (JSF) for every Sukhoi Flanker shot down.
Current and future RAAF air dominance is based on detecting targets at long range then destroying them using missiles such as the AIM-120 AMRAAM (advanced medium-range air-to-air missile).
AMRAAM has an extensive combat record and has successfully shot down Russian built aircraft in conflicts in Iraq, Kosovo and Bosnia.
The latest AMRAAM model has a range of almost 200 kilometres and a claimed 90 per cent probability of destroying its target.
But Dr Kopp said experience over the last 30 years has shown that beyond visual range missile shots were not very reliable.
"The Russian approach to solving this is to carry 2-3 times as many missiles and shoot them off in big salvos so you are guaranteed a hit," he said.
"The corollary of that is that fighters like JSF and Super Hornets are outgunned in this game because the Russians carry many more missiles. Once a JSF or Super Hornet fires off all its missiles, it''''s a sitting duck."
Dr Kopp said the latest Flanker aircraft, now entering service with some regional air forces, could carry up to a dozen beyond visual range missiles of various types.
JSF will be able to carry up to four AMRAAMs in its internal weapons bay. As many as four more could be carried externally, although at the expense of performance, extra fuel and a significant degradation of its stealth capability.
Super Hornets can now carry up to 10 AMRAAMs, again at the expense of extra fuel and performance.

UPI: China imitates Russian Su-27SK fighter

By ANDREI CHANG
Column: Military Might
Published: February 25, 2008
HONG KONG UPI, China, Based on the design of the Russian Sukhoi Su-27SK fighter, China has come up with its own domestic version, the J-11B multi-function fighter. Three J-11B prototypes have been manufactured since 2006. After their factory flight tests, they have been evaluated by the People''''''''s Liberation Army Air Force 1st Fighter Division, based in Anshan in China''''''''s northeast Liaoning province.
A Chinese military industry source has confirmed that pre-production of the fighters will begin this year. "We will not need to assemble more Su-27SKs, because it is old technology given from Russia," the source said.
The J-11B has undergone drastic changes from the original Russian design. A source from the Chinese aerospace industry says that except for the Russian-made engines, 90 percent of the major subsystems fitted on the J-11B, including the radar and optical electronic systems, are made by China. The Chinese aviation company AVIC 1 has already completed testing the 1474 serial radar system to be deployed in the J-11B. The fighter''''''''s weapons will also integrate indigenous systems.
A Chinese pilot with more than 20 years of flight experience expressed his high opinion of the Su-27 fighter, describing it as "very easy to fly."
However, as the source from the Chinese military industry points out, some of the parts used on the Su-27SK have a very short lifespan, which has led to a high rate of technical accidents. For instance, frequent problems with the fighter''''''''s infrared search and track system have restricted its use in the regular training of combat forces.
To investigate this issue, the author paid a special visit to the Ural Optical and Mechanical Complex in Ekaterinburg, Russia. A Russian source revealed that the company had signed two contracts with a Chinese company *****pply parts for an updated IRST system, the OLS-31E. Execution of the contract, valued at US$1 million, began in 2007.
Research and development of the China-made IRST system to be fitted on the J-11B fighters is already completed. The physical appearance of this new IRST is very close to the original Russian OLS-31E, making it appear to be an imitation e***ion of the Russian system with some upgrades. In fact, the overall performance of the J-11B is now on a par with the Russian-e***ion Su-27SMK.
The J-11B''''''''s fire control radar system uses mechanical scanning, integrates more functions and features a modular design. The fighter also features substantial changes in the fire control system and the ****pit so the J-11B will be able to fire China''''''''s indigenous PL-12 air-to-air missiles and a whole series of other precision-guided weapons. The ****pit has three large color multifunctional displays and two small color multifunctional displays.
In recent years, China''''''''s pace of development in airborne equipment has been very fast. The design of its J-10B ****pit has been quite precocious; the rear ****pit seems to have four multifunctional color displays and two small multifunctional displays.
In ad***ion, the J-11B will be fitted with China''''''''s indigenous strapdown inertial navigation system, 3-axix data system, power supply system, emergency power unit, brake system, hydraulic system, fuel system, environment control system and molecular sieve oxygen generation systems.
The fact that China is producing a large proportion of the J-11B parts domestically indicates that its demand for parts imported from Russia will decline dramatically during the second phase of the fighter''''''''s production. Also, some of the subsystems and equipment are compatible with those used in the J-10A and J-10B fighters.
It is expected that the J-11B''''''''s flight control system will also be manufactured in China. This was the leading reason why Russia could not determine whether China would continue to produce Su-27SK fighters in the next phase. In reality, the joint contract between Russia and China for the Su-27SK/J-11 development has now been virtually abandoned by the Chinese side without any consultation with Russia.

J-11
In the 1970s, Shenyang Aircraft Factory proposed to design a light fighter powered by the British Rolls-Royce Spey 512 engine, but otherwise similar to the MiG-19 then in service. Known as the J-11, the project was abandoned due to difficulty in obtaining the engines.[1]
New J-11
The new J-11 is a Chinese redesigned version of the Sukhoi Su-27SK air superiority fighter. Sukhoi originally provided kits to Shenyang Aircraft Corporation upon an agreement in 1995, but over time there were to be increasing Chinese content in the aircraft, with up to 70% of all Su-27 ordered by the PLAAF to be Chinese-made. It has been reported that Sukhoi agreed to an upgrade program, allegedly in 2001, with improved radar and attack avionics.
However, in 2004, Russian media reported that Shenyang co-production of the basic J-11 was stopped after around 100 examples were built, citing a source within the PLAAF suggesting that the basic Su-27/J-11 was no longer meeting PLAAF requirements. The PLAAF later revealed a mock-up of an upgrade J-11C in late 2002. It was equipped with Chinese anti-ship and PL-12 air-to-air missiles presumably for the role for a maritime strike aircraft.
Deployment
Currently, the PLAAF has seven divisions equipped with J-11, listed below[2]
PLAAF 1st Air Division based in Anshan, Liaoning, equipped with the J-11
PLAAF 2nd Air Division based in Suxi, Guangdong, equipped with the Su-27SK, Su-27UBK, and J-11
PLAAF 6th Air Division based in Yinchuan, Ningxia, equipped with the J-11
PLAAF 7th Air Division based in Zhangjiakou, Hebei, equipped with the J-11
PLAAF 14th Air Division based in Zhangshu, Jiangxi, equipped with the J-11
PLAAF 19th Air Division based in Zhengzhou, Henan, equipped with the Su-27SK, Su-27UBK, and J-11
PLAAF 33rd Air Division based in Baishiyi, Chongqing, equipped with the Su-27UBK
Design
The aircraft is a licensed co-production of the Russian Sukhoi Su-27SK. For more information on the design of the aircraft, see the Sukhoi Su-27 article.
Modernization
China is currently considering the use of its domestic WS-10A engine to replace the Russian Saturn Lyulka AL-31FN. The new WS-10A, reported to be an impressive 13,200kg thrust turbofan, could be in service in about 5 years. At the Zhuhai 2002 show a photo was released of a J-11 alleged to have been modified to test one WS-10A.[3] However, according to Russian media, in November of 2006, China has intentions to upgrade the current Flanker fleet''s engines and is planning to source the engines either from Saturn-Lyulka with their 117S engine, a development of the Lyulka AL-31F engine, which is planned to be the powerplant for Indian Su-30MKIs, or from Salyut, with their AL-31F-M1 engine, an improved variant of the AL-31F engine.[4]
Variants
In 2002, Russian media reported that Shenyang Aircraft Corporation was looking into replacing Russian-made J-11/Su-27SK components with domestic, Chinese-made parts. Specifically, to replace the Russian-made NIIP N001 radar with a Chinese-made fire control radar based on the Type 147X/KLJ-X family, the AL-31F engine with WS-10A, and Russian R-77 AAM''s with Chinese-made PL-12 AAM''s. One J-11 was photographed with an AL-31F and a WS-10A engine installed for testing in 2002. However, it was not until 2007 when the Chinese government finally revealed information on the domestic J-11: the J-11 used to test WS-10 was designated as J-11WS, and it was when state television station CCTV-7 aired J-11B footages in mid-2007 when the existence of J-11 with domestic components was finally confirmed officially.
J-11
The Chinese built Su-27SK with 70% components made in China, with some improvements over the original Su-27SK in the following areas: radar, flight intrumentation and added air-to-surface attack capability.
Radar: the original N001 radar on Su-27SK purchased by China in the 1990s is replaced by its successor, N001V, which like N001, can also simultaneously track 10 targets. However, when engaging a target out of the 10 tracked, the original N001 radar would lose all of the rest 9 targets tracked, and must restart a new tracking process after the engagement. N001V radar on J-11 overcomes this shortcoming so that during the engagement, the rest 9 targets tracked would not be lost. The major internal structural difference between the two radars is that the original TS100 processor in the older N001 radar is replaced by a more capable TS101M processor in the newer N001V radar.
Flight intrumentation: in comparison *****-27SK with only one small CRT mulitfunction display (MFD), J-11 has a total of two by adding an ad***ional one directly atop of the original small CRT MFD at the top right corner of the flight intrumentation dashboard. This new small CRT MFD is about the same size as the original one on Su-27SK, and it is located to the right of HUD.
Ad***ional air-to-surface attack capability: The ad***ional MFD is mainly used to control the electro-optically guided precision munitions such as TV guided or ImIR guided missiles in attacking ground and sea targets, since the domestic Chinese electro-optical pods and electro-optical guided precision munitions are extremely difficult to be directly integrated into the Su-27SK. The images and information for the electrical-optically guided munitions, as well as those provided by the domestic Chinese electro-optical pods can not be displayed on the original CRT MFD of Su-27SK, and they can only be displayed on the ad***ional CRT MFD added. Despite this added air-to-surface attack capability, it must be noted, however, J-11 still lacks the full air-to-surface attack capability of later models because due to the limitation of the radar, the radar guided air-to-surface missiles can not be deployed.
J-11A
J-11 with further radar and flight instrumentation upgrade, most notably with the adoption of EFIS in its avionics.
Radar: The N001V radar on J-11 is replaced by its successor, N001VE, which has the same tracking capability like its predecessor. The radar improvement is that in comparison to the older N001V radar which is only capable of single target engagement, N001VE is capable of simultaneously engaging two of the ten targets tracked with semi-active radar homing air-to-air missiles. The major internal structural difference between the two radars is that the original TS101M processor in the older N001V radar is replaced by a more capable BCVM-486-6 processor of the Baguet series processor in the newer N001VE radar.
HMS: A more capable domestic Chinese helmet mounted sights (HMS) first begun to appear on J-11A, which soon had became standard all version of J-11, including retrofitting earlier J-11.
EFIS: Most of the analogue dial indictors of the original Su-27SK are eliminated, replaced by four color MFDs, which are part of the overall EFIS system designed by China Aviation Industry Corporation I. There are three large MFDs that take most of the space of the flight intrumentation dashboard, with the MFD in the center is in a slightly lower position than the other two on the sides. A slightly smaller color MFD is located below the three MFDs, to the bottom right corner of the flight intrumentation dashboard. Since all of the official photos of the EFIS by China Aviation Industry Corporation I on J-11A released by the Chinese governmental authorities so far are full frontal views, it is difficult to confirm if these color MFDs are either CRT, or LCD as claimed by many domestic Chinese sources.
J-11B
This is the indigenous, Chinese-designed, multirole version which uses more Chinese components, including radar, engine, and missiles. China is interested in reducing its reliance on foreign technology for both cost reasons and a desire to improve its domestic research and design. It is reported that one regiment of J-11Bs are currently in service, but this seems to contradict with the latest information provided by the Chinese government: In May, 2007, the existence of J-11B was finally acknowledged by the Chinese government for the first time when the state-run Chinese TV stations first aired the report on J-11B in PLAAF service, which were subsequently publicized in various domestic Chinese media such as state-run websites and newspapers (like Xin Wen Hua Bao, New Culture Newspaper). However, the official Chinese report claims that there are only two squadrons of J-11Bs in service, instead of a regiment, which is consisted of three squadrons. According to the Chinese report, which is agreed by some western sources such as Jane''s Information Group, the J-11B is superior *****-27SK in the following areas:
The wide adoption of composite material (mainly carbon fiber) for the surfaces, reducing the weight of the aircraft for more than 700 kg, while the life of the composite part is increased over 10,000 hours in comparison to the original part built from steel.
Redesigned air inlets of engine intakes to reduce the radar cross section, this coupled with the adoption of composite material, and application of radar absorbent material has reduced the radar cross section (RCS) of 25 square meters of Su-27SK to just 5 square meters of J-11B, the same RCS as MiG-21.
Full air-to-surface / sea capability is added and J-11B is able to launch various precision guided air-to-surface and air-to-sea munitions.
Certified to be equipped with WS-10 (will be upgraded to WS-10A in the future) turbofan engine, which is claimed to be cheaper to operate than AL-31F.
Improved radar. The new radar is able to track 20 targets at the same time, and engage 6 of the 20 tracked simultaneously. The Chinese official report claims that the radar is better than the 147x/KLJ-X radar family, but stop short of identifying the exact type.
Fully digitized solid-state avionics has replaced the analogue one in Su-27SK. In the mid-2007, the Chinese governmental television station CCTV-7 released news clips of Chinese pilots in the ****pits of J-11B, with the LCD of glass ****pit of J-11B clearly visible, despite that the official report itself only claimed replacing the original avionics with domestic Chinese fully digitized solid-state avionics, and nothing of EFIS or glass ****pit was mentioned. In comparison to the earlier EFIS on J-11A, the most obvious difference is that LCD MFDs on J-11B are aligned in a straight line, instead of the middle one being slightly lower. The arrangement, appearance and layout of MFDs and EFIS of J-11B are similar to the general design concept of the west.
Though it has long been rumored that J-11B is aerial-refueling capable, it was impossible to determine if any aerial refueling probes have been added to the aircraft from the released official reports by the Chinese government. During an interview on a regular TV program of Phoenix Television that was aired in the evening of October 17, 2007, Professor Wang Xianghui (ỗZ<ổạ~ỗâ-) that the J-11B entering series production would be equipped with domestic engines.
J-11BS
Tandem twin seater version of J-11B under development, reportedly as the Chinese version of Su-30MK2/3. It is rumored that the letter S stands for Shuangzuo, meaning twin seater in Chinese. The existence of J-11BS is officially acknowledged by the Chinese government in 2007, and a large model of J-11BS was revealed public on June 9, 2007 during the opening ceremony of the new aerospace museum of the Harbin Institute of Technology at the 20-year anniversary of the establishment of its school of astronautics, where it is displayed. Some sources outside China have claimed that the successful development of J-11BS is one of reasons that China lacks the enthusiasm on purchasing Su-30MK3, but the Chinese government appears to be rather cautious, with official reports only claiming that the project is very promising, instead of declaring it is successful already.
Su-27SK Upgrade
Both the SUV-VEP air-to-air subsystem and the SUV-P air-to-surface subsystems of the Sukhoi Su-30MKK fire control system were adopted to upgrade the single seat Su-27SK in Chinese inventory, and a joint team of Tikhomirov Scientific Research Institute of Instrument Design (NIIP) and State Instrumentation Plant at Ryazan was named as the primary contractor to provide the Chinese with the upgraded avionics package. The modified SUV-VEP subsystem adopted to upgrade Chinese Su-27SK was designated as SUV-VE, while the modified SUV-P subsystem adopted to upgrade Chinese Su-27SK was designated as SUV-PE. The original analog dial indicator on flight dashboard of Su-27SK were replaced by two 6 in x 6 in MFI-10-6M and a MFIP-6 LCD MFDs. According to Russian claim at the 6th Zhuhai Airshow, over 60 Chinese Su-27SK have been upgraded by the end of 2006. The upgraded Su-27SK with the upgrade is claimed to have its overall combat efficiency significantly improved, approaching that of J-11B. It is not clear if China has continued such upgrade after 2006 since no more information was released.

Analysis: China eyes new Russian tech
by Andrei Chang
Hong Kong (UPI) Nov 23, 2007
A Chinese military source based in Beijing has said the People''s Liberation Army Air Force is negotiating with the Russian Sukhoi Aircraft Company on three new projects.
Military observers based in Moscow and Beijing say they believe the recent nadir of military cooperation between China and Russia is only temporary. China will have to rely on Russia to develop its military technologies, as Beijing has no other alternative.
The first new project involves Su-33 shipborne fighters. Experts from the Russian aviation industry are convinced that China is about to start the construction of an aircraft carrier.
"Up to the present, on the issue of the Su-33, China and Sukhoi have had three rounds of negotiations and have reached some agreement," said the source.
Nonetheless, he did not disclose what specific progress has been made in the negotiations, merely confirming that ad***ional rounds of talks will be held. A high-level source from Sukhoi confirmed his company is most interested in discovering whether the Chinese want to purchase whole Su-33 fighters or only require Su-33 parts, and whether they will request the transfer of production technology or design blueprints.
Other sources from the Chinese military industry said that several plans were involved in the negotiations on the Su-33. One of them is that China will buy a small number of Su-33, say 10 to 24, and later request that production technologies be transferred. However, the Chinese strategy is to use some of the Su-33 technology to develop their own shipborne fighter based on the J-11B assembled domestically.
The second project under negotiation involves the newest Su-35 fighter. At the MAKS 2007 International Aviation and Space Salon held at the Zhukovsky Air Base near Moscow in August, Chinese delegates took photos and videos of the Su-35 virtually every day.
"Several Chinese delegations have visited Sukhoi and raised technical questions," the Sukhoi company representative said. He said the two sides have reached a consensus and are now working on export plans.
"At least in the foreseeable future, China''s indigenous aviation technologies will not be able to produce combat aircraft similar to the Su-35," he said. "Our attitude on this issue is the same as the case of the Su-33; that is, we are only interested in exporting whole Su-35s. This is not what the Chinese delegates hoped for. They hoped to import only certain subsystems, for instance the radar systems or the engines."
The third project concerns the PLA Navy''s plan to import more Su-30MK2 fighters, or upgraded variants of the aircraft. No progress has been made on this as yet, however. A plan for China to import Su-30MK3 fighters, which was negotiated earlier, has not been carried out so far.
The possibility that the navy will continue importing Su-30MK2s or Su-30MK3s appears slim, mainly because it has already started to receive China-made JH-7A fighters. Meanwhile, the upgrade of the J-11B fighter aircraft has been very comprehensive. The fighter is now capable of launching precision attacks on battleships, and can basically meet the combat requirements of the navy fleet. China may not resume the import of Su-30MK2s unless the cost of the J-11B remains too high or comes close to the cost of the Su-30MK2.
Is there any possibility that the PLA Air Force may upgrade its existing Su-30MK2s and J-11s, or the Indian Air Force''s Su-30MKIs, to a combat platform close to the Su-35 standard?
Yury Bely, a general designer at Russia''s NIIP Radar Design Bureau, agreed to discuss the question. "It is impossible to import the Su-35''s radar system only," he said. Bely stressed that it would be more feasible to import brand new Su-35s than to try upgrading the Su-30MK2.
The Su-35 is equipped with the H035 passive phased array radar system, which has extremely powerful detection capability, Bely pointed out. The average output power of this radar is 5 kW, with peak output at 20 kW; thus the output power of the Su-30MKI and Su-30MK2 would be insufficient. When the H035 radar was tested on Su-30MK No. 503, the detection range was as far as 290 kilometers with 1 kW power output, he said.
