Defense spending cuts? What defense spending cuts?

Don't look now, but the United States Department of Defense just signed the biggest arms deal of the year, and potentially the biggest arms deal we'll see all year long. Valued at $11 billion, this is just about the biggest purchase of U.S. weapons systems by a foreign buyer since the monster $90 billion arms sale that the United States negotiated with Saudi Arabia back in 2010.

It promises to add billions of dollars of new revenue, and hundreds of millions of dollars worth of pure profit, to the bottom lines at Boeing (NYSE:BA), Lockheed Martin (NYSE:LMT), and Raytheon (NYSE:RTN). And in the slideshow that follows, we'll tell you all about it.
