Russia found out that the heavier SU-33, which is also based on the SU-27, was too heavy. Its T/W was inferior to the MIG-29 and did not allow for sufficient payload off a ski jump. <br />The new China ski jump carrier has an even shallower ski jump and that likely will translate into worse payloads (I am guessing).<br />J-20 with its delta wing will have a rather high stall speed and landing speed. Canards will improve take off and landing performances by re-directing airflow so the delta wing does not stall easily, that's why you see canards on Gripen, Rafale, Typhoon, Kfir, Cheetah, etc. You do see Rafale landing on a CVN but Rafale is a much smaller plane with some rather powerful engines with the same equivalent thrust to the F/A-18 (it was designed for the shorter catapults on the Charles de Gaulle). I do not think J-20 is optimized for carrier applications.<br />KQN<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-86946048539316952482018-05-23T00:55:20.894+10:002018-05-23T00:55:20.894+10:00@Pete/Sabastien:

As far as I know none of these stats have been revealed, and in fact the current engine is deemed insufficient by the Chinese. Furthermore I have a hard time believing that such a large aircraft could have a particularly energetic T:W ratio. Supercruise is possible, but so far as I know never claimed or demonstrated. Also the J-20 doesn't strike me as a very good candidate for CV work due to size. J-31 seems like a better fit, though it is unclear if this aircraft will even enter Chinese service.<br /><br />Cheers,<br />JoshJoshhttps://squidjigger.comnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-6155471141553188742018-05-22T15:35:08.942+10:002018-05-22T15:35:08.942+10:00Hi Sabastien

The J-15 Flying Shark fighters on China’s two Type 001 carriers also share common heritage in the Flanker family of aircraft, and pursuing a similar upgrade of the two-seat J-15SD seems plausible."<br /><br />China seems to be persuing the right strategy in just concentrating on the J-15 variants for its ski jump carriers.

I wrote a profile on the J-16D for th National Interest a while back in which I speculated that it would be easy to make a carrier-based version, and lo and behold... Very interesting point that these aircraft could team up with the J-20 in a similar fashion as the Super Hornet/Lightning pairing (though J-20 is not carrier based, it may have long enough range.)Sebastienhttps://www.blogger.com/profile/17864206803235345807noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-28280072205962829592018-05-21T13:31:04.495+10:002018-05-21T13:31:04.495+10:00J-20 are starting to fly combat patrols over China...J-20 are starting to fly combat patrols over China ADIZ, so it probably will not be too long before encountering Japanese intercepts? <br />Indian SU-30MKI claimed to be able to detect J-20 CAPs over Tibet but that may not means anything: J-20 during training in Inner Mongolia typically display Luneburg radar reflectors under their bellies.<br />KQN<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-12159682676580864262018-05-20T16:34:42.712+10:002018-05-20T16:34:42.712+10:00I thought I saw it stated somewhere that Australia...I thought I saw it stated somewhere that Australia was contributing to the next generation jammer along with USA, which should mean Australia will definately be getting them. I am not sure if it is monetry only or we are contributing some tech as well (like the latest CBASS torpedo).<br /><br />If the USN go with the conformal fuel tanks then I expect we would too as there is a stated objective to keep up with USN airframe upgrades for the Super Hornets (rather than let it slip as we did a few times with the legacy Hornets). We could even go first (though I doubt it). USN also keep track of what we do (eg we asked Boeing to modify our EF18G's to enable carrying of AIM9X as well as the standard EW setup - something I believe they are now looking at).<br /><br />The real question is how good is their jammer in reality & can we jam their jammer or will it end up cancelling each other out. If the latter, then it will be back to IR based missiles. Good thing we added them to our EF18G's. We may need to add MICA.<br /><br />I also worry about adding more & more options onto the F35. Sensor fusion is great but at some point you will overwelm the single crew member with information. There are already stories of them turning off elements in the helmet displays because they are getting in the way. Most dedicated EW & heavy strike aircraft tend to be dual seat with the 2nd seat occupied with a specialist operator & console.<br /><br />Regards<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-54297942841065490452018-05-19T11:40:10.445+10:002018-05-19T11:40:10.445+10:00China has acquired from Russia 3 generations of ja...China has acquired from Russia 3 generations of jammers, Gardeniya (on SU-27), Knirty (with SU-30) and recently Khibiny (on their SU-35). They exist in wing pods, centerline pod and internal configurations.<br />I assume the home grown version is likely improved upon Gardeniya and Knirty but I am sure they will learn quickly from Khibiny. China is likely more advanced than Russia with fab, but the US still hold an advantage. That is not to say China will not close the gap quickly as this is one of their 2025 strategic initiative and Xi is pouring train loads of money into it, especially after the ZTE embargo. That embargo will hurt China in the near term but in the long term US manufacturers are going to definitely feel the heat (we can see that initial wave already with smartphones)<br />KQNAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-87002608547746421092018-05-19T11:22:43.906+10:002018-05-19T11:22:43.906+10:00I agree that Australian F/A-18 need to upgrade to ...I agree that Australian F/A-18 need to upgrade to the NG jammer, but I would add that they also need the conformal fuel tanks to eliminate the blind spots they currently have with external fuel tanks. Australia may also want to fund an integration of Meteor on their F/A-18. Today, NATO only medium range IR AAM is the French MICA and that is also something worthwhile to integrate in conjunction with an IRST pod.<br />KQN<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-70690817084494011262018-05-19T01:23:12.180+10:002018-05-19T01:23:12.180+10:00@Pete:

Presumably the ESM component is in the wing pods of the J-15 as it is in the EF-18G. Interestingly these pods don't seem to use ram air turbines for power - presumably the aircraft provides the power. This would probably limit peak transmit power if it were the case. The new NGJ for the US uses GaN emitters to boast peak transmission and a new form of ram air generator inside the pod to generate 90kW of power.<br /><br />Cheers,<br />JoshJoshnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-36260584695044719972018-05-18T21:54:28.363+10:002018-05-18T21:54:28.363+10:00@Pete:

That statement was fully explained, but I suspect the implication is that all of the ESM functionality of the EF-18G is handled by the systems already present in the F-35, and all that would be required is software integration and an active emitter source. In which case a F-18G purchase may not be the best path for countries buying F-35, though in the case of the RAAF they not only already have EFs, they also bought a number of fighter types wired up to be converted to EF standard with minor modifications (removal of gun and wingtip pylons and appropriate emitters/receivers added). NGJ is slated for F-18G integration first, and the low RCS of the F-35 is less useful for standoff work so it would make sense to for the RAAF to purchase NGJ as soon as it is available to them for their F-18s - the USN will have already handled the integration work for the type.<br /><br />Cheers,<br />JoshAnonymousnoreply@blogger.com
