The Lockheed-Martin F-35 Lightning II has been delayed for years due to a faulty electrical system, corrupted displays which do cause the helmet sight-system to become blinded, and a RR lift fan that sometimes malfunctions (which is highly dangerous for a transitional flight aircraft). IOC has been pushed back continually and the original contract for the USAF, USMC, USN, and RN has been reduced. I wonder if it will end-up like the F-22 with just a small amount produced that does nothing to replace the aging inventory of 1970s-'90s military fighters and strike aircraft the US possesses. As it was early on the F-35 lost the 27mm Mauser BK-27 cannon for an indigenous revolver cannon and the three variants for the USAF, USMC/USN, and RN ran into commanality problems. What good is the strike version that carrier JDAMs but ony 2x AIM-120 AMRAAMs for self defense (along with 1 gun)??? Will UCAVs have to escort it and do the jamming as well over targets??? Another bird that should be scrapped...
