Chengdu J-20 5th Generation Aircraft News & Discussions

That's what make F-35 and J-20 different. F-35 is the next generation of fighter. Because they are intended to replace the older fighters. While J-20 is a high tech, powerful, elite aircraft. That is not intended to replace the older designs. But to work together with the older designs as the elite. It's like J-20 is the special force of the fleet. Well, at least right now.

Yes, J20 and future naval variant J31 will serve as strategic front line snipers but will be built in numbers when ready.

Future air engagement in case of US invasion, the J10 & Flankers will serve as decoy to lure in F18, F15, F16, F22 and F35 while J20 & navalized J31 will be flying ahead undetected to launch missiles taking out conventional fighters first.

Conventional fighters will then use jammer and countermeasures to spoof incoming missiles while performing evasive maneuver fleeing from F22/35 while J20/31 will try to acquire lock and launch missiles on the F22/35. Stealth vs stealth will involve visual range engagements aided by tactical satellite uplink view.

I hope PLA leadership take this seriously. :lol:

As far as I can see, J-20 and others are mainly for defensive use although some stealth hunting can be done. Same also applies to their naval fleets.

Offensive operations with real significance will be done using new concept weapons, typically near space, hyper-sonic weapons. They have been working on that for 2 decades, deployed quite some large scaled multi spectrum satellite constellations, fielded some battle ready, rocket boosted gliders and are still advancing very fast on a a couple of different directions including the scram jets. I am pretty sure they will keep on maximising their advantage on that.

That's why the US, in response to such threats, has been exercising the Rapid Raptor concepts since 2014.

Nice to see you around, feel free to debate anything and compare. You're ex military expert in radar detection, you sure know how it works and the downside of it against stealth target.

Since radar can't detect stealth aircraft from far, a good satellite is all you could count on before they get close to naval fleet or shore. The conventional fighters are the good decoy to distract the stealth aircraft. Like your country exercise where the F-15s stood zero chance against the F-22 (doesn't count evasive maneuver against missile), the only way is to make the F-22 launch missile to trace its position with assistance from satellites. The F-15s could only go evasive maneuver to spoof the incoming missiles before they could get close (only if there are F-15s left). If there's F-35A (on F-15 side) flanking from the side at high speed towards the possible F-22 location or if it is seen on satellite, the F-35 could get into right detection range to track and kill the F-22 while it is busy engaging the F-15s.

*The F-117 could only be spotted on old radar below 10Nm before it could be tracked (rumored below 5Nm) and shot at in Serbia. Maybe AESA radar would work better*

Conclusion is, if stealth vs stealth, both might need to get into visual pod range in order to spot each other if AESA can't see below 20Nm, 10Nm or less. IRST might or might not work at max range. This means dogfight is still important. Forgo dogfight will only repeat another US Air Force disaster in Vietnam.

J-20 is for defensive at the moment, in future if necessary will go on the offensive. Think they'll focus on new small diameter armaments for the J-20 to carry more bombs, missiles in its main bay. Same goes to navalized J-31, might not be built for export market unless stealth no longer classifieds since US is selling F-35s to NATO & allies that will definitely reverse engineer the F-35 stealth coating in secret. Unless US selling the downgraded low RCS version instead of the actual stealth materials which is possible, don't think US will do that when it is the only country with 2nd generation stealth materials. China & Russia probably at either 1st generation (salvaged from F-117 wreckage) or already at 2nd generation (hacked information from US F-35 & some of the hired engineers that once worked for US manufacturers went to join China). The latest news, the JSDF crashed F-35 wreckage is believed to have been located (not realized until the wreckage is confirmed salvaged by US & Japan).

China Naval Fleet for now is on the defensive, their conventional carriers are mainly to safeguard the South China Sea, Yellow Sea and entrance to Pacific Ocean up to Guam and some of the pacific islands. Not meant for long range operation therefore they prefer conventional because it is lighter, faster and less risky maintenance. China invested in space technology because the good top down view that could see through clouds and bad storm is necessary to check for any stealth invader. Top down attack defenses, rail gun, hypersonic flight vehicles in progress.

Both will keep coming up with better new toys to counter each other, good for technology development.
 
China's new J-20 stealth fighter may be ready for a fight sooner than you think

NEW YORK — 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.

Gen. 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 envelope 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.

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 the 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 nonnuclear 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 buildup, 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.

“At the moment, we are measuring a special stealth device. Assuming that the aircraft captured by the radar looks as big as a sparrow, then this device will make the aircraft smaller than the bee.” In the feature film, the researchers of the China Electronic Technology Group (CETC) are so shocked. It is speculated that the RCS value of J-20 歼-20 is likely to decrease to the lower limit of 0.001 m2 in the future.


歼20采用特殊装置瞬间变身蜜蜂 雷达要没“战绩”了


专题片中,中国电子科技集团有限公司(CETC)的科研人员经过多年的攻坚克难,最终成功掌握了RCS测量方法,并运用该技术对歼-20开展了测量评定工作。并且和歼-20的“娘家”成都飞机制造厂开展合作,大幅度降低了歼-20的RCS数值。眼下,歼-20的RCS数值被控制在了0.1㎡的下限,这就相当于一只小鸟的RCS。

“目前,我们正对一部特殊的隐身设备进行测量。假设雷达捕捉到的一个飞机看上去跟麻雀差不多大,那么这个设备就会让飞机变得比蜜蜂小。”专题片中,中国电科的科研人员如此爆料。根据推测,歼-20的RCS数值在未来很可能降低在0.001 ㎡的下限。

Are you saying current J20 RCS is equal to Sparrow ???
