Hello Marcos,
As I see it, performance tables on F-35 today are not so relevant since the test aircraft have not opened yet the full flight envelope and there are still limitations on AoA, altitude, speed etc. The simplistic theories of wing area etc are also of limited use since the blended, lifting body design of F-35 is the result of way more complex computational models.
To me, all evidence points out that:
- a combat-loaded F-35 will have comparable to if not better performance than a clean F-16/F-18 class fighter while offering considerably more range;
- it will see those 4-gen fighters first so no need to fight physics to "get into their six"
- the F-35B beats the Harrier in all relevant aspects by a large margin, whether it is payload, range, speed, manoevrability, avionics, ease-of-flight, etc ... and with some good luck the UK will even have a carrier for it!
And do you really think the test programme is running that much worse than that of V-22, NH-90, A-400M, Tigre etc. ?
