Andrew_FOn my MA-1 Flight Jacket label in the pocket says "Made in China". This is the same style, so probably not. Regardless, it's a great product and I'm very happy with my purchase.
For what it's worth, via Wikipedia: "the end of the Cold War brought the "Peace Dividend" and by the early 1990s DOD spending had decreased by 75%. Liberalization of trade barriers and a reduction of duties also led to a breakdown in the American apparel industry. "Made in America" was not so sought after when an identical product could suddenly be made much cheaper in China."
