Vietnam tested.
This has just been let loose to float on the Internet.
Has anyone heard of it?
Sounds kind of like an early version of the metal storm to me. Not sure how practical it would be on a helicopter.
Metal Storm has fewer barrels, and each barrel is multi-shot.
This brilliant idea reminded me more of a claymore mine, only slightly safer to the people on the “safe” side of it.
It’s actually more like the bridge guns from the Civil War, so called because they would be placed at chokepoints and rigged to fire all barrels when the enemy charged their positions. Can’t really see how it would be much use on a helicopter though, considering that those don’t generally land on bridges and you’d have to be pretty lucky to get the enemy to attack in single file otherwise.
