Yeah, no.

a) The Yak-141 has two lift engines that are separate from the main powerplant.

b) Even if it was the same (which it ain’t) using the same engine configuration alone would hardly count as a copy, otherwise every jet aircraft ever built is ripping off Frank Whittle.

Anyone could get all technical and make counter claims about all the claims about Russian “copies”.

Lets just put it this way. Byoin’s comment that “outside of the US, everyone copies” is a completely false and ignorant statement.

And anyone who actually agrees with that ignorance, deserves to be bombarded with all of the evidence that proves the claim to be false.

The J 20 is a Mig 1.44 with F-35 nose and intakes. There is murkey evidence of China buying the Mig 1.44 plans and there is clear evidence of China spying on the F 35.

Chinese Businessman Pleads Guilty of Spying on F-35

Mar 24, 2016 – Chinese Businessman Pleads Guilty of Spying on F-35 and F-22 …. Industrial Corp., which is building a C-17 look-alike dubbed the Y-20.

some russian fanboys can’t get over the fact that China has surpassed them in aviation.
So lets say the mig is really the basis of the j-20, then maybe the russians should’ve done the same too so they can get a real 5th gen fighter instead of a stealthy su-27

Haha that is just a ridiculous statement.

Russia does not have the capability to design a smaller medium range missile or bomb like those in the picture. they require large engines to fly and thus a large frame, and now no room to fit into any supposed bay. thats why to this day, we see the j-20 with all its bays open but pak-fa is still having trouble.

The J 20 is designed by Russia.

i want rumors on J-20 weight

Mig 1.42 is comparable.

Empty weight: 18,000 kg (40,000 lb)
Loaded weight: 28,000 kg (62,000 lb)
Max. takeoff weight: 35,000 kg (77,000 lb)

Mikoyan made use of weight-saving materials in the construction of the aircraft, with aluminium-lithium alloys making up 35% of the empty weight, steel and titanium alloys (30%), composites (30%) and others (5%).[23]

for sure just producing some more F-15E would have cost less, leaving some money to pay back debt before it spiral out of ability,
the question is: will there ever be a US president with the resolve to pay back and balance budget ?
what is more, will consecutive presidents adhere to balanced budgets ?

could have made a specialized first attack stealth jet in small numbers. Then just use the F 15e for everything else.

Remember and keep the below illustrative map… that is how the situation is likely being moulded by the US & allies. And when you see something like this (or near to this) happening in the months ahead, you can be sure that Russia has lost it after putting in so much effort with a brilliant start to the campaign!
Just like that Olympics volley ball match I mentioned earlier.

First thing Russia decision makers need to understand is that, when you start giving military support to an ally, your support cannot be anything less than a full-scale support for the allies, but Russian support since that “ceasefire” in Feb 2016 was less than adequate and selective. There cannot be any major turnaround unless Russia increase its various assets including the much needed gunships.

^ I dont need to explain that map or how that is being “developed”…. The only winner here in that (above) case will be the US.
1) Keep Turkey happy (No Rojava close to actual Turkish border)
2) Keep Kurds happy (a Rojava in between Turkish proxies controlled territory and Syria on the expense of Syrian territory)

And they all live happily ever after with oil trade… like the earlier IS-Kurds-Turkey partnership which saw some disruption once the Russians started striking those long truck chains

The US like usual, is trying to do the impossible. Sure. Day to day, some of the plan looks like it can work. But it won’t. You are way overblowing the US’s position here.

This will turn back into a conventional war soon enough. Russia . Hezzbo and the SAA will roll on.

The report nails it perfectly of Russian actions, cant agree more on what the report says of Chinese views & discussion regarding Russia’s rather modest action in Syria after the ceasefire & “mission accomplished” withdrawal.

I wish I’m wrong, but… post that stupid “ceasefire” and “mission accomplished” stuff, Russia is showing how to loose a winning (mil situation/momentum pre-Feb 2016 ceasefire)/winnable (restore & increase the military assets to fully support manpower constrained SAA & allies) game. It now looks very much like the Rio Olympics men’s volley ball match for bronze between Russia and US where Russia won the first two sets and then the US team came back to win the next three and take away the medal, leaving Russia with nothing. I wish Syria doesn’t go that way. High time Russian decision makers/planner took a review and corrected their mistakes and priorities….. or like the so-called Russophiles from $hitoles claim there is nothing wrong with Russian planning/executions and completely blame it on the ‘incompetent’ Syrian forces.

I don’t know what gave you the idea that the withdraw was akin to mission accomplished. They were putting pressure on Assad and everyone and giving a chance for peace. They also wanted to prove that they were not getting bogged down and committed. Nobody was going to make a point of bleeding them.

The US put a team of rag tags together by over-paying all of them. They took an empty town yesterday and they are already fighting each other. Yet you make it sound like these rag tags are blitzkrieging across Syria.
