It's called field testing!
I'm sure that they collected tons of valuable information, showing how the defense system works in actual practice against actual Russian missiles - something that's a little, ahem, difficult to simulate on American soil.
Bravo! An excellent expenditure of funds!

Russians will probably also be glad that they know they need to improve their weapons. Better to know than not know.
If not used, it’s not that long until they are obsolete and in need of being scrapped.
I’ll bet the Ukies don’t even get our latest and best upgrades or production...
Granted that at $3 million a pop, I’d be saving them for defending high importance targets or vs. Russia’s best missiles.
