The total proposed American defense budget for 2008 is more than half a trillion dollars—with $75 billion of that set aside for research and development. For decades, the Pentagons investment in science and technology has produced widely hailed achievements like the Internet and the Global Positioning System. It has also backed quixotic and costly failures, like space-based lasers. And sometimes it has gone off the deep end, funding such things as psychic spies and weapons that defy the laws of physics.\r

The Department of Defense began systematically funding basic and applied research in a big way after World War II. Today the Pentagons investment in science R&D remains a cornerstone of the countrys national security strategy. Yet in the aftermath of the low-tech attacks of 9/11, the growing insurgency in Iraq, and the threat of worldwide terrorism, technology experts both within and outside the Pentagon are questioning whether Defense Department research is producing the results that America needs.\r

So what are we getting for our money? That $75 billion budget covers a vast array of projects, from perfecting new weapon systems like the Joint Strike Fighter plane to studying pure physics. Focusing on the research side of R&D, DISCOVER looked at four key areas where the military is placing its bets: hypersonic vehicles, laser technology, using information technology and neuroscience to combine human and machine on the battlefield, and employing sociology and psychobiology to combat terrorism.\r
