UPDATE (via SOC/CDF): taken in November 2017 at Pingyuan (23.725094 N 103.817836 E) it is IMO not a J-10 but it is a triplane with canards, wings, tails.

Any guess?

Similar thing can be found from Google earth in 2016 already.

I agree, not a J-10, the trailing edges of the canards are not swapped backward like J-10.

The retired pilot from PLAAF (a well known pilot) provided his opinion (no classified info, so take it with a grain of salt) in this video:

• At 11:00 he said the new engines mounted on J10 were for testing TVC
• At 22:00 he said the new engine on J20 can not be WS-10 Taihang. My guess is he might be saying the engines are Russian since WS-15 is still years out
• At 26:00 he said the stealthy H-20 does not physically exist, yet, meaning the project may exist but no flyable prototypes

As you advised, it is just a talk show, I don't put much thought in it.

However, regarding J20's engine on prototype 2021, what he said was, it is definitely not Taihang, (based on the tech standard of 70s), it must be WS-15

, he did not finish his sentence before the host picked up. He certainly did not mention Russian engine on prototype 2021, I listened until the subjected moved to bomber without finding him mentioning Russian engine.

Anyways, he is not involved in any of these projects even though he is a pilot, so just some talk.

do you think China will get one of the white birds? or to develop its own H20?
how's China's progress in stealth bomber H20?
25/1/2018 Russia test flight the newest edition of Tu 160M2, flight height was 300m. in attendance also President Putin..
what a beauty....
enjoy...

Never, I am aware of the "buy Tu-22m and Tu-160 among some Chinese netizens", but I can't understand why some Chinese always want to buy from abroad. Nobody is going to sell their crown jewel, and no strategic security can be bought or relying on foreign things. It is like "buying nukes" or "sharing wives", that is not going to happen.

Russian beauty!

Even with H-20 I don't mind having some of these. After all US still has B-52!

But I don't think that time will ever come.

Guys ... is it really necessary to always quote the full post with all images???

Something very much different ... for some maps in the making I'm looking for Combat Radius data, but unfortunately quite often only maximum range is given.

So is the a "general" method on how to estimate/calculate the Combat Radius from maximum range? I know it vastly depends on several factors and for most specifications given both, it varies of between a factor 1/2 to 1/3 ... Any help?

This is what I got so far:


H-6G: Combat radius 1,800 km (972 nm)
Su-30MK2 / J-11BH: Combat radius 1,340 km (724 nm)
J-10AH: Combat radius 1,300 km (702 nm) + tanks / 550 km (297 nm) w/o
JH-7A: Combat radius 900 km (586 nm)
J-8FH: Combat radius 1,000 km (540 nm)

Yes, actually combat radius usually IS a a certain value of ferry range. It is never half of the range though. For a high altitude flight, it may be perhaps one third of ferry range. Less if plane is really heavily loaded. If there's some low altitude penetration run, usually last 100-150 km, then a strike configured plane is better modeled with just one quarter of ferry range to represent its combat radius. For empirical data please see Standard aircraft characteristics documents from US DoD of various US planes (f16, f15, f14, f4, etc, etc) You will see these fractions are usually a good rule of thumb.

I just watched a fly past of our F-7GS and Kfir C2 and something I've notice the past few years is that the F-7GS much quieter than the Kfir. Why is this? Speed they are travelling are roughly the same (eye-ball version) but the noise of the Kfir signiciantly higher. Is it the afterburner? (I did not see them light up though)

I mean today 2 F-7GS passed by and the sound was kinda "meh", or a "silent cruise" but the single Kfir C2 that followed pierces your eardrums.
