Il caccia cinese J-20 è un aereo da caccia stealth di quinta generazione sviluppato dall’azienda aeronautica cinese Chengdu Aircraft Industry Group negli anni duemila e dal 2016 in fase di preproduzione. Ha una velocità massima di 2,100 km/h con velocità di crociera di mach 1.83 Mach. Il raggio di azione varia dai 1,300 ai 1,700 km, con una velocità di salita di 300 ms.
Si riporta che dovrebbero essere quasi equivalenti agli F-35 americani, che però continuano a presentare molti malfunzionamenti.
Secondo alcune fonti, la Cina avrebbe già schierati quasi cento J-20.
«Il caccia da superiorità aerea di quinta generazione Chengdu J-20 in Cina continua a dominare i titoli sin dall’entrata in servizio nel marzo 2017, anni prima che gli analisti occidentali prevedevano fosse pronto al combattimento e recenti informazioni indicano che circa 100 aviogetti da combattimento d’élite potrebbero aver già lasciato linee di produzione. Il J-20 rappresenta il primo caccia di quinta generazione stealth ad entrare in servizio fuori degli Stati Uniti, ed è un analogo diretto dell’F-22 Raptor statunitense entrato in servizio nel 2005. La struttura della piattaforma da caccia bimotore fu progettata per facilitare lunga autonomia, carico utile elevato, quota operativa elevata, alta velocità e manovrabilità, ottimizzandolo così per le missioni di combattimento aria-aria avanzato, come il Raptor. Il J-20 è uno dei tre caccia cinesi della nuova generazione dell’Aeronautica dell’Esercito di Liberazione del Popolo (PLA), insieme al caccia multiruolo leggero di 4.ta++ generazione J-10C e al cacciabombardiere J-16, con comparabili sistemi di guerra elettronica, di avionica e armi, ma privi dell’avanzato profilo dalla ridotta sezione radar del J-20. Questi tre aviogetti svolgono ruoli altamente complementari e la loro sinergia darà al PLA una capacità operativa considerevolmente maggiore della loro mera somma.»

– Head of Air Force’s Pacific Command sees China testing limits
– J-20 deployments would mean ‘greater threat,’ Brown says
China may declare its first stealth fighter operational this year as it also develops long-range bombers capable of carrying nuclear weapons, part of a regional buildup by Beijing that the U.S. is closely monitoring, according to the U.S. Air Force’s Pacific commander.
General Charles Brown, the head of Pacific Air Forces, said the stealthy J-20 fighter could “possibly” be operational this year, a move he said would signal “greater threat, greater capability” for China in the Pacific. He went on to emphasize that U.S. efforts to counter those developments include rising deployments of next-generation F-35 jets and continuing overflights of strategic areas such as the South China Sea.
“My sense of the way the Chinese operate is somewhat incremental,” Brown said in an interview this week at Bloomberg’s headquarters in New York. “They’ll continue to push the envelop to figure out does anybody say or do anything — if you don’t push back it’ll keep coming.”
Fielding the J-20 would add to what’s already the region’s largest air force and world’s third largest, with more than 2,500 total aircraft including 1,700 combat fighters, strategic bombers, tactical bombers and multi-mission tactical and attack aircraft, the U.S. Defense Intelligence Agency said in a report earlier this year.
In its annual report on China’s military, the Pentagon said that “the J-20 may have begun active service in small numbers, possibly with a testing and training unit.”
“Chinese engineers report successful testing of a solid-fuel ramjet missile engine, and they suggest this will enable the J-20 to carry future Mach 5, 300 kilometer-range air-to-air missiles,” according to the report published Thursday.
China’s J-20 fighter is part of a modernization effort that’s been “closing the gap with Western air forces across a broad spectrum of capabilities, such as aircraft performance, command and control and electronic warfare,” according to Defense Intelligence Agency report.
Brown also said he thinks China is moving to develop dual-use bombers that would be “similar to our bombers” in terms of being able to carry nuclear weapons and non-nuclear precision-guided weapons. “I don’t think it would be too far off the mark to say they could do that as well,” Brown added, without indicating whether China may have a stealth bomber capability.
Acting Defense Secretary Patrick Shanahan, in a statement Wednesday for the House Defense Appropriations subcommittee, said a Chinese long-range bomber “if successful, would make it only one of three nations” to “possess a nuclear triad” of land, sea and air-based nuclear capabilities.
The U.S. has a number of ways to counter China’s build up, Brown said. That includes being unpredictable in deployments of the B-1B, B-52 and B-2 bombers. The B-1B, Brown said, is now qualified to carry a new Lockheed Martin Corp. anti-ship missile, a few of which have been stockpiled in the Pacific region.
Brown, a four-star general who has logged more than 130 combat flight hours out of 2,900 overall, was on the U.S. East Coast this week to speak with Asia experts about the challenges facing his command. He started in the job more than eight months ago after serving as deputy commander of U.S. operations in the Middle East and head of the air war against Islamic State in 2015-2016.
A key issue for Brown in his latest post is “how do I gain a greater understanding of how China operates — not only their equipment capability — but how they operate, how they command and control. I want to understand what makes their blood pressure go up” so as to avoid miscalculations.
“Their propensity to fly out over the water has increased over the years,” he said.
It’s not just the U.S. noticing the increased Chinese capability, Brown said. He touched briefly on the State Department and Pentagon’s review of a potential sale of new F-16s to Taiwan. President Donald Trump’s advisers encouraged Taiwan to submit a formal request for the jets. That request would need to be converted into a formal proposal by the Defense and State Departments, and then Congress would have 30 days to decide whether to block the sale.
“There’s been a little increase in tension there recently, which may be the impetus” behind Taiwan’s request, Brown said. The Beijing government considers Taiwan’s fate a “core interest” — more important than almost any other issue, and has increased pressure on countries and multinational companies to avoid actions that could imply sovereign status for the island.
The U.S., wary of antagonizing China, hasn’t sold advanced fighter jets to Taiwan since President George H.W. Bush announced the sale of 150 F-16s in 1992. The Obama administration rejected a similar Taiwanese request for new jets, agreeing in 2011 to upgrade the island’s existing fleet.
Brown has more than a passing familiarity with the F-16 — he said it’s his favorite military aircraft of the numerous ones he has piloted. In addition to the F-16, he has flown the AH-64 Apache attack helicopter, V-2 tilt-rotor Osprey, AC-130U gunship, B-1B, B-2A and B-52H bombers, C-130J transport and KC-135 tanker, among others.
