The gun doesn't work, but the F35 is combat ready

The Marines announced that the first 12 aircraft F35 squadron is now combat ready.   There is a long list of technical problems, needed software upgrades, but the Marines say that what they have is good enough to fly combat.  Nothing was said about the engine flex problem.  When the F35 pulls Gs the whole engine flexes, allowing the compressor blades to rub on the engine casing.  One F35 was destroyed in the resulting engine fire.  They didn't say, but I suspect they have limited the amount of G the aircraft can pull.  The gun is supposed to start working after some more software upgrades.
