Sure, It Was The "Ghost of Kuwait"...

 ... but even US Air and Space Forces magazine has to admit: 

Iran has developed air defense systems that can use passive infrared sensors rather than radar to target aircraft, a solution that previously proved effective in Yemen when employed by the Iranian-backed Houthis, which downed around half a dozen MQ-9 Reapers during Operation Rough Rider last year. The stealthy F-35 evades radar, but infrared sensors home in on heat. The F-35 is now one of around 20 U.S. Air Force aircraft known to be damaged or destroyed in the nearly three-week-old Iran war.

So, let me clarify. 

1. F-35 DOES NOT "evade radar", it is pure BS. It has lower signature in the front semisphere. It is totally detectible;

2. What is "around" 20 aircraft? 19? 22? 25? 

Well, make your own conclusions. But, it will take USAF some time for getting used to that, since this is the FIRST time in many decades that it encountered an actual air defense which is newer than was AD in Yugoslavia--by a generation, if not two--and that getting high on fairy tales by 404 on issues of AD and air combat is not good for your health, both physical and mental. I know they still run Top Gun: Maverick in selected theaters. I do prefer, however, the first one--fun and great soundtrack. Ah yes, Kelly McGillis at her stunning top self. To those who still consume this "stealth" BS, MQ-9 Reaper drone is also "stealthy", yet somehow they are falling from the skies. Yes, it was very successful against mighty Taliban air force and air defense. 

Here is poor-poor dear Stephen Miller's reaction during Trump's speech on his victories in Iran. 

Something went wrong, but what? /s
