Folks,
Really, much ado about nothing. Look here:
http://www.baesystems-gyro.com/Products.htm BAE has competitive items. As does Thales (France). If they don't get them from inside a 737 and send us money to have them, they'll get them elsewhere.
This is really a fringe thing. It's not an overt, absolute US military advantage at issue. The Chinese, frankly, probably already have sensors like this they build themselves, for less money, that work as well. This is not envelope pushing technology.
Remember the the so called West has an embargo on certain items against China. Corruption comes in all forms and peculiar places, the US not withstanding.
