Gosh, I hate to sound provincial, but we can’t buy an American made system? It would have the advantage of keeping Americans employed and the technology local. I remember when the OSI bought some Israeli machineguns. Congress went ballistic and they dumped them. The Brits were buying grenades from Switzerland, which stopped providing them when the Brits joined the coalition against Saddam Hussein. The Spanish bought the cannons for their Armada from the English, who provided them in so many calibers the logistics of a sea battle became impossible. (Their own ships had only three types.)
For the most part, it’s idiocy to buy weapons from somebody else. (BTW, we’re buying Russian made helicopters for Afghanistan. Yes, there are reasons, but it’s helping the Russians at the expense of American suppliers. Now the Russians can say, “Why buy Sikorsky when even the US Army buys our models?” )
Even american made weapons are subject to “globalization”. This approach will surely bite us in the butt.
I don’t know what it is like today, but in the mid 80s we had gone decades without an effective version, it isn’t an easy niche to fill, and we need to find the best.
