I do not know about details. I just know that there were a series of talkings about "renewals" in AF, from bases to air defence systems, radars and anything else.Grippen is 55% made out of US components - Swedes are unable to sell this airplane without permission from US.....
try to compare J-20 with MiG 1.44 - not exactly the same but similarities are "easily noticeable" i would say...I more wonder how Russian fighters compare to their Chinese knock-offs. I suspect the student has surpassed the master.
Su-27 vs. Shenyang J-11
Su-30 vs. Shenyang J-16
How China made the J-16 fighter better than the Su-30 - Air Data News
The Chinese newspaper Global Times, controlled by the government of China, published an article last week with the testimony of an Air Force pilot from thewww.airdatanews.com
Not related, but Chengdu J-20 vs. Sukhoi Su-57?

Sharing components and solution between military and commercial engines is nothing unusual. Especially cfm-56 is father of at least two families of military engines - F110 and M88. Everything comes to the very tiny details in the engine design - simply coping large components will not work - magic is buried in materials, design of cooling system, ACC, structural resonance and surge preventing, and in general engine control system - coping of this in simple reverse engineering process is close to impossible - of course you may learn this on your own mistakes but it will consume serious amount of time and equally reasonable amount of money...A colleague who once worked for a not-to-be-named intelligence agency commented to me that Chinese avionics and human factors considerations in their Flanker reworks are a full generation ahead of their Russian counterparts. The J-11 and J-16 have cockpits stuffed full of MFDs and their avionics are - reportedly - mostly derived from Western civil systems from the late 1990s/early 2000s. They also have some structural differences - more composites and some internal structure changes - which cut several hundred kgs in weight from the airframes.
The big unknown for me are the engines (Shenyang WS-10). China has struggled for a long time with issues around thrust, reliability and operating life. The WS-10 is based off the core architecture of the CFM56, a 1980s civil airliner engine which is about as reliable as they come, and some other technology borrowed from the AL-31.
The WS-10 has been in development for better than 30 years at this point. The initial versions were reputed to have TBOs as low as 30 to 40 hours (mostly because of problems with erosion/disintegration of fan blades and production quality issues), engine lives under 200 hours and demanded as many as 15 man hours of maintenance for every hour of flight.
China reportedly 'borrowed' fan blade technology from Rolls-Royce in the mid 2010s, which has solved some of the problems. But, even the more mature WS-10B and WS-10C are reported to be maintenance hogs. Last I read, the WS-10B was roughly at AL-31FM reliability levels - i.e. about the same as an engine developed in the Soviet Union in the 1970s and reworked in Russia during the 1990s. Ballpark figures of life before rebuild of anywhere between 250 to 400 hours and full engine life of 1000 to 2000 hours.

Hopefully not F-35 or J-20.I wonder what aircraft the Russian Air Force will be fielding in 2033. Ten years from now the Su 27-33 that survived the Ukrainian War will need replacing.

And what of their nuclear submarine fleet? They're one neglected system's failure away from another Kursk. What's their naval budget looking like as the army gobbles up the rubles.Their production numbers spell as dismal future, especially under a sanctions regime.

I find it amazing that at least a hundred thousand families in Russia have seen their sons killed or wounded and no one is marching on the Kremlin. When the Kursk went down there were riots in Russia and Putin himself was at risk. Nowadays, nothing?Putin has mortgaged his country's future with this war.

Russia was a very different country back then. Worth reading this interview to lawyer Boris Kuznetsov. He represented the families of 55 of the drowned Kursk seamen. Now he has political asylum in the United States.I find it amazing that at least a hundred thousand families in Russia have seen their sons killed or wounded and no one is marching on the Kremlin.

The subs seem maintained well enough.And what of their nuclear submarine fleet? They're one neglected system's failure away from another Kursk. What's their naval budget looking like as the army gobbles up the rubles.
