Yet the fanboys still insist that the 35 would defeat any current fighter if it came down to a WVR knifefight, mainly due to 'Fifth generation' (™) and 'sensor fusion' (™). But it would seem that currently the Lesser spotted fat Dave cant pull off manoeuvres that even WW2 pilots would have considered 'warming up'.
What is really interesting about the news coming out of P+W is that they hope to know the issue by end of Sept yet are still delivering engines that they will later have to recall and re-engineer once they have come up with a solution. At first it was suggested that it was a faulty batch of titanium, that seems to have dropped and now there is talk of designing in a 'gulley' for that set of blades or reinforcing the whole engine to eliminate flex, that is massive work.
We may never know how much this ends up costing but it is going to be a shocking figure
