Used to be all US military planes were made in the USA. Now even USA made aircraft aren't entirely made in the USA.
Sure would have helped this American company if the got the military trainer contract instead of the Brazilian company.
Buy American doesn't mean much anymore as our own government doesn't do it either. Regardless of the price, it would be dollars spent in America. Taxed in America. Re-spent in America.
The T6 is nothing more than a PC-9 that's built in Switzerland by Pilatus and modified in the states by Beech. Who in turn raises the price by millions to sell it to the government. So what's the difference if SNC (an american company) does the same thing with the Embraer?
The problem is the US aircraft manufactures dont build this type of aircraft and are not inclined to spend the money to do so.
