@oralloy,
There may well be such a consensus and there may be some real substsance to it. I'll readily confess I haven't followed these details for the F-35 closely at all. That said I do know from long experience that there's always a lot of propaganda and BS out there on both sides of the issues on new aircraft procurements. The economic stakes are very high and as the number and frequency of the development of new aircraft types is reduced they get even higher.
The tradeoffs between the maneuverability of air to air weapons and that of the aircraft that launches them have been around for about 50 years. The lessons learned in the 1970s and 1980s may have different applicability today, as missile design improves and tailchase guidance is replaced by intercept control, and the systems doing this become more compact and reliable. The fact that a guy in an F-16 could get in the six o'clock position on an F-35 doesn't necessarily mean the new aircraft can't do its mission.
I'll take the trouble to better inform myself about the current challenges facing the F-35 introduction. However, I haven't seen any commentary here that gives me any confidence in the criticisms so abundant here.
Most military aircraft exhibit disappointments and defects relative to the wishes of their users. Some are later successfully upgraded to correct them. The P 51 Mustang involved a then radical new wing cross section, but the initial model was an underpowered dissappointment. Later it was extensively modified to incorporate a much larger Rolls Royce in line piston engine and the rest is an aviation legend. Others remained failures: the F-102 was designed to be at least transonic, but couldn't do better than Mach 0.92 because of shock wave issues. (Later the so called "area rule" was developed to overcome this problem. It also had a thin delta wing that gave it great maneuverability for a few swconds, but it slowed down very fast in a high g turn and was of limited use. A decade later the F-106 used the same design principles but corrected these defects. The Navy F-4 Phantom was designed as an air-to- air missile only fighter - no guns. It was more maneuverable by far than the F-104 or F-105 and a lot faster than the F-101 or F-102. A MIG 21 could out turn it, but in a fight the Phantom could do a vertical scissors to beat a MIG. Later in use it proved to be also an excellent attack aircraft with a good payload and acceptable range.
The Navy F-14 was an excellent fighter, but the variable sweep wing needed to give it good loiter fuel performance added weight and degraded its maneuverability compared to the contemporary Air Force F-15, which is a truly superior design. An example of the difficult tradeoffs involved here.
The new generations of aircraft incorporating computer augmented fly by wire control systems, lightweight structural materials and now stealth introduce a new set of capabilities, side effects and difficult tradeoffs. It's an imperfect art.
