Early in Vietnam we had an H21 shot down with a crossbow. It pass through an open door and hit a hydraulic line and forced it to land.
What would you think the range and guidance of that missile is. I have never seen one, but I am going to guess that once she goes down range a bit, those three penetrators will be ejected forward with much energy. Look at them close and you will note they have little fins on them for stability.
I sent in several suggestions on ammunition. Some were actually used and some were not. I always wanted to see a fluchete round for the 120mm main gun on the tank with fluchettes about as large as your thumb that worked like the beehive rounds or the old (true) sharpnel rounds that had an ejection charge in the projectile that would go off down range.
My guess is why the weapon you posted was developed, was that it was hard to penetrate a modern main battle tank with missile by use of a shaped charge. This would do it with kenetic energy.
First things first, EOD. The rest of the story is buried in Foggy Bottom.
The witnesses to the streak rising from the ocean to the aircraft were ignored, compromised and marginalized. I've seen Puff the Magic Dragon at night shoot a finger of light from the dark to the dark ground. Knew which way it came from. I've seen missile launches from the ground into the air and from the air watching them come up. Not something you forget, not something you mistake.
