Some bad news for F-35 programme: in addition to performance shortfalls, cost overruns and huge vulnerability to even small-calibre weapons due to the fuel tank design, F-35 is also in danger of weather. Namely, lightning.
It seems that, due to the deficient fuel tank design, F-35s natural namesake is very dangerous for the jet. If F-35 is struck by lightning, it could ignite the fuel
It is not only problem with lighting. Reductions in safety measures, done to save weight, have also left jet vulnerable to even small arms fire. For one, its fuel is kept all around the engine. Second, it is not self-sealing.
Another problem with fuel tank prevens it from rapidly reducing altitude.
More shortfaillings that articles didn’t mention include reduced level of radar stealth, as well as very large IR signature. Vaunted 360*360 vision helmet had problems with lag, though it could have been fixed,
Apparently, Lockheed Martin fails to understand difference between war and video games. Warfighting weapons should have minimum of electronics necessary: anything above that just means less reliability, and harms performance in required areas.
