A modified version of China's first stealth fighter jet, the J-20, has formally entered mass production, with upgrades earning it a place as a fifth-generation fighter jet, according to a military source close to the project.
The moment was marked at a ceremonial unveiling of the modified J-20B stealth fighter jet on Wednesday attended by many senior military leaders including Central Military Commission (CMC) vice-chairman General Zhang Youxia, the source said.
Zhang is the second-ranked vice-chairman of the CMC and is in charge of weapons development for the People's Liberation Army.
“Mass production of the J-20B started on Wednesday. It has finally become a complete stealth fighter jet, with its agility meeting the original criteria,” the source said.
“The most significant change to the fighter jet is that it is now equipped with thrust vector control.”
Thrust vector control (TVC) allows pilots to better control the aircraft by redirecting engine thrust.
In 2018, China debuted its J-10C multirole fighter – fitted with a WS-10 Taihang engine – at the China air show in Zhuhai, putting the aircraft through its paces in a performance that indicated that China had succeeded in thrust technology.
While the TVC technology had been applied to the stealth fighter, the J-20B would still use Russian Saturn AL-31 engines because more work needed to be done on China's WS-15 engine, the source said.
Chinese engineers have been developing high-thrust turbofan WS-15 engines for the J-20, but that work has fallen behind schedule.
“The Chinese engine designed for the J-20s still failed to meet requirements, but its development is going quite smoothly, and it may be ready in the next one or two years,” the source said.
“The ultimate goal is to equip the J-20B fighter jets with domestic engines.”
China was thought to have built about 50 J-20s by the end of 2019, but problems with the jets' engines delayed further production plans.
Meanwhile, Lockheed Martin's Fort Worth assembly plant in Texas delivered 134 F-35 stealth fighters in 2019, three more than its target and 47 per cent more than its output in 2018, according to the company.
China's first batch of J-20s entered service in 2017 when the US decided to deploy more than 100 F-35s to Japan and South Korea that year.
The J-20 was meant to be a fifth-generation fighter jet on a par with Lockheed's F-22 Raptor and F-35 Lightning multirole strike fighters.
Fifth-generation fighters are defined by their stealth technology, supersonic cruising speed, super manoeuvrability, and highly integrated avionics.
But the earlier version of the J-20 was described by Western media as a “dedicated interceptor aircraft” because of its lack of agility.
“The launch of the J-20B means this aircraft now is a formal fifth-generation fighter jet,” the military source said, adding that Chengdu Aerospace Corporation (CAC), which manufactures the J-20s, had received “heavy orders” from the PLA.
CAC set up its fourth production line in 2019, each one with a capacity to make about one J-20 a month.

“The hardware is good,” Lt. Gen. Michael Schmidt said. “It’s the rate at which they’re producing them to meet our production and retrofit needs."

Seminar can be viewed at: http://saab-seminar.creo.se/180516/annual_gripen_seminar_2018 Article on Skies Magazine: Saab positions Gripen E as Canada's next-generation fighter Saab Group is confident that its single-engine Gripen E remains a viable contender for Canada's next generation fighter aircraft fleet, even though there are currently no immediate plans for Royal Canadian Air Force (RCAF) pilots to actually fly the aircraft. This was according to Richard Smith, head of Gripen marketing and sales during a May 16 briefing on Gripen market opportunities worldwide. He confirmed the planned visits included “site surveys and also some more senior visits as well, but at the moment, no plans for a flight evaluation.” He offered no details on who specifically would be visiting, but welcomed a suggestion that Prime Minister Justin Trudeau could be on the list. Canada is one of a number of countries Saab is targeting as a customer for the Mach 2 delta wing/canard fighter, the first variation of which entered service with the Swedish Air Force in 1997. Development of the Gripen E, featuring a General Electric F414G engine and an upgraded electronic warfare system (EWS), began about 2014 and it was first flown in June 2017. It is now said to be on track for delivery to the Swedish and Brazilian air forces. Smith said he expected that “continued dialogue so far this year” with Canadian government representatives was setting the stage for an early draft proposal, possibly in the third quarter of 2018, followed by the government's request for proposal for 80 aircraft early next year. He said the Gripen is suitable for all RCAF operations, including the high north, the Arctic and forward operating bases, which he said are “very similar to what we have in Sweden.” He later added that Saab would “tailor” its offering to Canada, as it would to other prospective customers with different operating environments. “Value for money, the industrial packages, that's what makes the Gripen rather unique and rather attractive.” On the seminal Canadian question about the reliability of a single-engine aircraft in Arctic and maritime missions, Gripen test pilot Mikhal Olsson said it had never been an issue. “I've been flying fighter aircraft since 1996 and I've been stationed . . . up in the Arctic,” he said. “I've been flying over the Atlantic, I've been flying across the sea eastbound to India (Saab is proposing the Gripen for the India Air Force), and every time I've been in a single-engine jet. I've never, ever, been worried about the engine [due to built-in redundancies]. “We have a really reliable system.” Olsson also said that as a “smart fighter” with net-centric technologies, a new sensor suite and long-range weapons, the E model is tailored to an “much more hostile and . . . much more unpredictable” operational environment where “new conflicts arise and disappear much quicker that we've seen before.” Gripen EWS sales director Inga Bergstrom added that electronic warfare was not the aircraft's primary function. Rather, EWS was “an enabler to . . . a successful mission” and because it was upgradeable software, it could deal with evolving threats. Asked about having to compete in some markets with used aircraft, Smith said these were, at best, an interim solution. “We're going to operate it for 30 to 40 years,” he replied. “Second-hand fighters . . . need to be replaced after maybe 10 years, and the capability that we bring is somewhat different to those old fighters. . . . Even though there has been, as you say, some headwind recently, I remain very optimistic about the outlook for Gripen both short term and longer term.” Jonas Hjelm, head of Aeronautics at Saab, acknowledged that although the company can't compete with used fighters because of the price difference, he agreed that the upgradeable Gripen could be operated for potentially more than 40 years without having to go through a new acquisition process, so the total package “makes sense for very many of the countries that are now in process of actually selecting a new fighter system.” Asked how the Gripen could compete with “stealth” platforms, Hjelm declined comment on competitors' aircraft but conceded that it was a difficult challenge. Calling stealth a “fashion word,” he said that while the newest Gripen variants have “stealth features,” Saab has chosen “different paths to have a low signature.” Besides, with “every smart technique you come up with to defend yourself, there will be a pushback from the other side to detect you . . . . We continue all the time to see what we can develop . . . to become more invisible.” https://www.skiesmag.com/news/saab-positions-gripen-e-canadas-next-generation-fighter/
