When I saw this on the news last night, the story was about the fact that 1/3 of the manufacturing will be outside the US. The complaints were that this change in contract (previously Marine One was manufactured by Sikorsy, which I guess is all US) cost US jobs, and comprimised security because the President's helicopter will be manufactured in part by non-US manufacturers. Dealing with the second complaint first, that is the batshit craziest argument I've heard all week -- security and safety procedures on Marine One are, no doubt, the best that humanity has come up with. The first problem is nothing new, though I guess that it hits the military/defense industry is; I suppose it was only a matter of time.
Doing some belated research, I suspect the decision was made based on the appearance of the respective presidents:
Sikorsky's president, Steven Finger
Lockheed Martin's president/CEO, Robert Stevens
And, if for some reason you're into pasty defense tycoons with tiny mustaches,
here's a HUGE pic of the latter.
