Chinese Stealth Goes Operational, Carrier Program and Export Initiatives Accelerate



By Tom Demerly

China Has Emerged as a Preeminent Global Strategic Super Power: What Does It Mean?

During the past five years China’s defense programs have not accelerated, they have increased by multiples into segments the Chinese had not previously been involved in. The introduction of a developmental aircraft carrier program, the fielding of an operational stealth fighter, the deployment of the world’s longest range ICBM and several new state-sponsored defense programs including tactical aircraft and helicopters intended specifically for export sale signal a parallel emergence of China’s global defense doctrine along with their dominant economic influence.
But what are China’s strategic and tactical air capabilities and, more importantly, what can we theorize about their intentions not only in Asia, but around the world?
China’s new defense and aerospace initiatives are a strategic necessity to provide foundational security for their rising economic influence globally.
Two years ago, in 2015 The International Monetary Fund (IMF) ranked China as the number one economic superpower in the world. That year China surpassed the United States based upon the purchasing power parity of GDP indicator (gross domestic product). The IMF reported that China produced 17% of the world gross domestic product in 2014 passing the U.S. GDP of 16%. China’s increased global influence has inspired low and middle income countries to emulate China’s approach. These Chinese allies now engage in partially state-sponsored rapid economic growth including the Latin American countries, Brazil, Argentina and Columbia as it emerges from a protracted drug war. India and Pakistan are now also aligned with China on several significant defense and economic initiatives.
While the subject of China’s emerging military is vast, there are several standout defense aerospace programs that provide an insight into China’s global motives.

China’s Operational Stealth Fighter: The J-20

China’s Chengdu J-20 stealth fighter has just officially entered active service with the People’s Liberation Army Air Force (PLAAF): “China’s latest J-20 stealth fighter has been officially commissioned into military service, Ministry of National Defense spokesperson Wu Qian told global media in a September 28, 2017 press release on the Xinhua.net and the official state defense media website.
Analysts suggest the J-20 is likely a medium-long range interceptor roughly analogous to the interceptor role of legacy aircraft like Russia’s older MiG-25 Foxbat, albeit much more sophisticated, and comparable to a Gen. 5 fighter.
There have also been comparisons to the U.S. F-22 Raptor, although the F-22 has emerged in combat in Syria as a precision strike low-observable aircraft in addition to its air superiority role. Western observers have suggested the primary low-observable capability of the J-20 is from the front of the aircraft, but perhaps not at other aspects, suggesting the J-20 is optimized for the interceptor role at least initially.
At different times, both in 2016 and 2017, there were unconfirmed reports that China may sell the J-20 to Pakistan in what would be the first-ever sale of a stealth air superiority specific Gen 5 aircraft in the export market (the multinational F-35 is described as a multirole Joint Strike Fighter, not exclusively as an air superiority interceptor like the J-20 or the U.S. F-22, which has not been exported outside the U.S.
Given this and more information about the J-20 it can be reasonably suggested that this aircraft is intended primarily for defense of Chinese air space and, if exported, some of its border allies. Sharing air defense with friendly border countries makes sense since China shares a border with a staggering 14 different countries. The U.S. only borders 2.

50 Shades Of Sukhoi

by Bill Sweetman

T-50-5, fifth development aircraft in Russia's stealth fighter program, has turned up at the Zhukovsky flight test center in a new two-tone blue-grey paint scheme.

It looks a bit like an early-World War 2 US Navy scheme, the bane of a young model-builder because Humbrol paints were not formulated for easy merging. I don't think it has anything to do with a carrier-based T-50, however. 

Clearly, someone in Russia has been doing some thinking about visual camouflage - which, unlike radar camouflage, has not often been the subject of intense, consistent scientific study. A few years ago, the Su-35 appeared with a jagged dazzle pattern that recalled at World War 1 warship.

Like those schemes, and like some of the camouflage schemes that U.S. Navy Cdr. C.J. "Heater" Heatley developed with the aid of artist Keith Ferris, the aim is to deceive rather than to conceal. The idea of dazzle on ships, for example, was to make it hard for a submarine commander to discern how fast his target was going, or even in which direction. 

The T-50-5 scheme seems to be influenced by two theories of vision. First, at long distances, visual perception is dominated by monochrome: the eye can see colors but is cued by light and dark. Second, contrast is important to perception, and a sharp-edged object is seen most easily. Consequently, a grayish color is the best camouflage whether the background is earth or sky, and deliberately blurring edges makes the aircraft less visible. 

One engineer who had worked with Heatley, by the way, told me that the camouflage was too effective: the risk of collision during training was unacceptable. Another interesting observation is that it took a long time for anyone to realize that the most visible color in daylight is black. That's why RAF trainers are painted black. What about the F-117? It was painted black because when it was introduced, a senior USAF commander did not believe that it could survive in daylight, and consequently ordered the jets to be painted black to make sure nobody tried it. 

South Korea to obtain 40 F-35As

  GREG WALDRON SINGAPORE

South Korea will obtain 40 Lockheed Martin F-35A fighters under its F-X III requirement.
A report by state news agency Yonhap quotes the country’s Joint Chiefs of Staff (JCS) as saying thatSeoul will obtain 40 F-35s starting in 2018, with an option to buy 20 more aircraft.
The deal will be conducted through the US government’s Foreign Military Sales mechanism.
"The F-35A will be used as a strategic weapon to gain a competitive edge and defeat the enemy in the early stage of war," Yonhap quotes the JCS as saying. "The South Korean military will also use the aircraft to effectively deal with provocations."

Deliveries will begin in 2018, says Yonhap.
"We will continue to work closely with the US government to meet the Republic of Korea Air Force's fighter requirements," says Lockheed. "we greatly appreciate that the Republic of Korea is pursuing a fifth-generation solution to meet their demanding security needs." The company confirms that is can supply aircraft in time to meet Seoul's 2018 objective, and in the F-35's Block 3F software configuration.
Seoul will also obtain an additional 20 fighter aircraft of unspecified type, but the timeframe and details of this acquisition are not clear.
This additional requirement would appear to leave room for Boeing and Eurofighter, which pitched theF-15 Silent Eagle and Typhoon in the original 60 aircraft F-X III competition, to make a significant sale in South Korea.

At a recent defence exhibition in South Korea, Boeing dropped its F-15SE proposal in favour of an aircraft it dubs the “Advanced F-15” (above). Eurofighter continued pitching the Typhoon.

An industry source familiar with South Korean defence requirements says today’s F-35A announcement stems from a 30-man team recently established by the air force to push its case with the country’s JCS, which has ultimate authority over force improvement decisions.
The JCS will submit this recommendation to the Defence Acquisition Program Administration (DAPA), which will negotiate the final contract. The air force team will also play a role in the acquisition of South Korea’s indigenous KFX fighter and a four-aircraft tanker requirement.
This should have the effect of reducing DAPA’s say over platform capabilities and relegate it to a contract negotiation role.
The original F-X III requirement called for Seoul to obtain 60 new fighters. The only aircraft to come in under the DAPA’s budget of won (W) 8.3 trillion ($7.7 billion) was Boeing’s proposed F-15SE, an upgraded version of the venerable type with low observable features and other improvements.
In September, however, Seoul decided to re-tender the competition following the air force’s reiteration that it wants a stealth aircraft to fill the requirement, and a public relations backlash in South Korean media against the selection of the F-15SE.

Chinese Stealth Jet Emerges

Note: this article from www.defensetech.org


Is this a mockup or not? It looks like a real version of China’s long rumored J-XX fifth-gen fighter with a pilot or ground crew member climbing into the cockpit. While Russia is developing a fifth-gen fighter, the Sukhoi PAK-FA, it remains to be seenhow long it will take to field the Russian jet. China on the other hand, is on the rise and seems to be quickly getting better and better at everything it does; from cyber war and IT to, perhaps, building and fielding fighters.
Remember in 2009 when U.S. Defense Secretary  Robert Gates said China would have no stealth fighters by 2020 while the U.S. would have hundreds. Well, he backtracked on that statement earlier this year, saying that the U.S. will have a significant lead in the numbers of stealth jets by the end of the decade. Maybe China wanted to show off the new jet to say this might not be the case? Who knows?
Still, while the airframe looks nearly complete, no one knows what the planes weapons load, engines or avionics and sensor suite will look like. Remember, in the 21st Century, it’s not just about stealth; it’s the sensors, communications and data fusion tools that give fifth generation planes a real edge.
One thing’s for sure, this will give F-35 Joint Strike Fighter backers a boost when arguing why that program is indeed necessary. It may also help stir up more support for the development of sixth-generation air superiority fighters now that the F-22 is nearing the end of its production run of less than 200 planes.
