Yak 141 and F35B similarities and differences a technical comparison thread

It is no secret that Lockheed Martin and Yakovlev worked closely and cooperated in a joint development and research project in the early 90’s on fighter vtol technology with Lockheed even granting money to Yakovlev in return for a technology transfer. Not surprisingly the lift mechanism on the F35B is virtually identical to the Yak141 where the rear engine rotates and pivots downwards in exactly the same way as on the Yak141,the only difference is the Yak141 had two smaller lift jets in the front behind the cockpit vs a single larger lift jet for the F35B.
Also the aerodynamic configuration and layout of the F35 is extremelly similar to the Yak141,the vertical stabilizer and wing shape is also very similar as is the shape of the fuselage. Yak141 wingspan is 33ft vs 35ft for the F35B and F35A. Both have quite small wings except the F35 wingloading is even heavier as its much heavier than the Yak141.
The length of the F35 at just 51ft is very similar to Yak141 if its massive rear fin extensions are not included.
