Guys ... I know we can discuss hoe reliable this Tempest-mock up is and probably even more how likely it will ever fly in that configuration, but You need to differ: The Tempest is clearly stated as a mock-up only. It is clearly labeled as a concept at an airshow to show BAE's aims to develop a future fighter and I think we all know that BAE more than once proved its capabilities to finish a design. If the Tempest ever will succeed is unknown and - esp. in mind of the Brexit - highly questionable, but that's not the point for now.
On the other side the Qaher 313 is labeled as a super-duper close to operational fighter, hyped as a "basis for a 6th generation fighter" and so far all analysts agree that the first one unveiled is a plain simple plastic mock up and the second one - already most surprising - did not fly.
So mocking it and putting both in the same league as some try to make fun is in fact quite lame and tells more about the political standing, the lack of technical understanding and knowledge of the poster than on these two most different projects.
