The J-20 Stealth Fighter’s Weapons Bays

 

Here you have it, pictures showing China’s J-20 stealth fighter’s weapons bay doors open.

It’s a big jet and these images appear to show its multiple weapons bays. You can see the smaller lateral bays squeezed into to the space forward of the main landing gear and the engine inlets. These side bays are apparently meant to carry short range air-to-air missiles (AAMs). Here’s another great picture of them. In the image below, it looks like you can see the larger, center-line bay open (or just a landing gear door shown at a weird angle, but I don’t think so). That space may be designed to carry larger AAMs such as this new missile.

Above images via China Defense Blog.

I posted the following images to give you a better sense of the space found between the landing gear and engine inlets and the overall layout of the belly of the jet. The last picture shows the diverterless engine inlets head-on. In addition to aiding engine performance and reducing radar signature, these ‘bumps’ in the intakes can also create space for weapons bays. Finally, we’ve published this picture before but it gives you a great sense of just how big the J-20 is.

Here’s a Photoshopped image showing the weapons bays of an F-22 on the J-20 that someone is trying to pass off as real.

So the thought is the bays are only for carriage of AAMs? I haven't been following the J-20 too much but is this just an air superiority fighter or is it a multirole aircaft? Seems pretty silly that it'd have to carry A-to-G ordnance externally only.

It looks like it is primarily designed for a last ditch anti-ship role with fighter capabilities. Why last ditch? Because if our Navy got close enough to where this would be effective, it would be pretty much game over.

You're assuming a situation where both sides are already in an active war.

If there is something going on in the south china sea (frankly, pick one – Spratly islands, Taiwan, whatever) causing major tensions and the US moves a carrier in as a diplomatic show-of-force (much like it did with the 1995 Taiwan Straits Crisis), you are parking yourself voluntarily within strike range.

Which is what the whole anti-access thing is supposed to be; not "We Declare War" and the USN comes in with weapons free rules of engagement. Any fleet in the world will lose at that point. It's more a case of whether they dare to place a ship somewhere that, in case of the balloon going up, the PLA get a number of 'free shots' at it.

that's mental masturbation.

US navy is easily the most overrated (paper tiger) navies in the world.

You've been brainwashed by slimy US propaganda apparatus (e.g. the mainstream media)

usa is not the sole country with a carrier. since it is an aircraft, i'd say it's meant for a less advanced foe, like india for example…

That said, India has its own fancy new fighters that the PLAAF may end up fighting in the distant future. Not as stealthy, but Russian aircraft built around maneuverability and maybe powerful radar and long range missiles.

J-20 is an air superiority fighter, just like the F-22. It is not designed to be a strike fighter like the F-35.

Our theories ranged from a long range fighter-bomber that would launch ALCMs against ships to some sort of AAM-truck. For the first image, that open door looks like it leads to the inlets: wouldn't it be a maintenance hatch? Same with picture two. Some sort of bleed-off from the inlets, since you can see /stuff/ inside? Picture three and four show ports that are square-shaped, and probably not well-sized to release payload.

Yes all speculation about. Only The Big Camerade knows its purpouse. What I can not understood why we keep geting pic "stolen pics" again again and again. Why not build a Chinese Barrier….or going the farest airport in Manchuria….(Russians!!). Well…the Center Empire its big enought. Someone with speculation that seems truly?

Such small weapons bays for such a large fighter seems the F-22 can carry far more weapons than this Chinese trash. with its weapons bays so small i doubt it can carry serios air to ground weapons either.

The J-20 will dominate the F-35 as it will carry longer range AAMs and as there is no funding in sight for the F-35 to carry 6 air-to-air missiles internally. Bye, bye US air superiority

Reply

blight July 6, 2011 at 7:49 pm

If the F-35 has a smaller radar fingerprint, then you'll need more missiles.

Crash project: USAF needs a "small diameter missile" to increase missile throw counts (though range remains an issue)

Reply

aSDF July 7, 2011 at 10:57 am

correction: 6 missiles. there is no way it could carry 8 aamram internally afaik.

If that bloated pig is really supposed to be an air superiority fighter than I'd say we're safe from Chinese military technology for a bit longer. It'll be interesting to see how much of this aircraft is a design exercise and what a production J-20 will look like. Not that the Pak-Fa is all that sleek and trim, but I'd think with the Russian design help that the jet would be a little more realistically scaled. It's about the size of an F-111… doesn't look like it'll be much of a dogfighter.

Wrong, it is about the size if YF-23.

David Kendrick July 7, 2011 at 1:39 pm

Size = range, think closer to F15c fuel capacity with thirsty engines which will be replaced with copies of the current F22F119-PW-100 by espionage. With air refuelling such a large 'fighter' could reach Australia or the Pacific coast of the USA without being intercepted, both nations relying on distance with much of their armed forces deployed away from the home nation, the weak underbelly – the civilian production, infrastructure and softer targets such as the home bases for the B2 and F22 fighters are vulnerable.

As for dogfighting, China already has every Russian missile design to choose from and as for technology's raw materials and finished goods it is the source for most of the worlds, as well as the cheapest source, simple tech upgrades in sensors, countermeasures can be rapidly applied cheaply – a mediocre Hurricane with the addition of radar, thrust vectoring, and sidewinders in 1940 would have wiped the floor with the Luftwaffe.

The question is what China wants these wonder toys for, how many it has in reality, how fast can they be produced, what is it going to do with them, who too and when. At the moment it is like Army group Patton

Most likely it is to force a second cold war with a poison debt laden America, never actually crossing swords but saber rattling until she finally expires from military overspending.

First off, size doesn't equal range, weight and fuel capacity does.

Second, you think this plane could just swan into CONUS? What do you think the people at NORAD do? Sit around all day jacking off to porn on their super big screens?!

Third, there were no AIM-9 (sidewinder) missiles in the 1930s-40s.

I'd like to chalk this down to "lost in translation", but I seriously doubt thats the case…

Considering 9/11, I think you actually should ask NORAD that question…

Reply

blight2 July 10, 2011 at 12:51 pm

NORAD's job is to defend the perimeter from Soviet bombers from entering American airspace. It was never intended to shoot down domestic airliners that strayed off course. We've never had "dead man switch" setups for aircraft in American territory, where when pilots failed to report or do something the aircraft would be assumed to be hijacked.

In most cases, the responsibility to control airspace would fall to the air traffic controllers. They noticed the hijacked craft changing courses, but did not know or assume a hijacking until it was too late. They're not even networked with the military, which presumably would not be tracking civilian flights. Even then, the military abandoned 24/7 alert squadrons once the Cold War was over, a practice presumably brought about by Bush Senior or Clinton, but not reversed by Bush Jr (unless you buy into the 9/11 conspiracy theory which would suggest that national security was deliberately compromised to ensure the success of a terrorist attack, or the other conspiracy which assumes a false flag operation by the United States against itself.)

psypher July 10, 2011 at 1:49 pm

…actually thats more of a question for the FAA

blight July 10, 2011 at 2:24 pm

FAA doesn't have interceptor squadrons to shoot down every aircraft that goes off course. NORAD is geared towards external threats. FAA is oriented towards ensuring aircraft go from point A to point B. Large capability gap when it comes to dealing to finding hijacked aircraft out of the mess of civilian air travel.

psypher July 9, 2011 at 6:40 am

Oh yeah one other thing, dog-fighting is with GUNS, the advent of missiles spelled the end of dog-fighting as we knew it….

It looks like the same missile packaging arrangement as the F-22. The side bays only have one door instead of two, but it is the same location. It also looks like they went with a single door on each side of the main (lower) bays, where the F-22 has smaller bi-fold doors that lessen the effect on handling qualities. Bigger doors might force resctrictions on launch parameters relative to F-22. The F-22 can shoot while maneuvering hard and scooting fast. Maybe the J-20 gave that up to save weight, complexity and risk.

what we really need to concern ourselves here is how to stop the slants -oh sorry i meean china from stealing U S military techs funded by hardworking taxpayers, by now we are suppossed to have learnt our lesson after the stole the secret of the w88 warhead,no ? they have stolen americas submarine technology,as well , the list cooud on to forever, what is happening to us? America need step up hard on counter inteligence and prevent further leaks of our sensitve techs, and apprehend those res ponsible crushing them completely,

its so funny to hear ppl who know everything about nothing talk. The 9/11 tragedy occured and they knew the planes were highjacked and as for the 24/7 alert squads we still have those xD just so u know. we have people on alert 24/7 at all times. military doesnt shoot down a civillian aircraft full of civillian passengers the area they were flying over was heavily populated so we were in other words powerless to do anything we do something and possibly cause an even greater disaster then what occured flying over a large city and taking something of that size down lets put that into reality. lets say its 9/11 all over again but this time the 2 airliners that slammed into the trade center were taken out every1 on those aircraft die. keep in mind that we are also over new york city. large flamming debris would rain own on the streets, homes, and local bussinesses the death toll might even reach higher then that of 9/11 granted the number of firefighters and police lost may be reduced but the amount of civillians casualtties would dramaticly increase.

9/11 was actually a false flag "Pearl Harbor" operation by a small but influential and murderous faction inside the US government and the US military.

…interesting. But doesn't that go against Posse Comitatus (in this instance using military assets for the surveillance and interdiction of civilians/privately owned assets in CONUS)? I'm not trying to be a smart ass, I'm genuinely curious.

Reply

blight July 14, 2011 at 5:10 pm

That's a serious gap right there, especially since "law enforcement" has no capability to deal with hijacked aircraft. But arming law enforcement helicopters with Stinger missiles (or worse) sounds like a really bad move…?
