Defence research: Still in the lead?
Abstract:
DARPA's leader today doesn't agree that the agency is in decline. Tether points to a host of projects developed in the 1980s and later, such as unmanned aerial vehicles, as well as lesser-known advances such as research on solid-state photon detectors, which enabled night-vision goggles, and integrated circuit research that helped lead to modern mobile phones. Tether also points to miniature global-positioning system receivers and DARPA's funding of gallium arsenide research (for use in semiconductors at a time when the commercial industry viewed such an investment as too risky). Today, he says, nanotechnology is a key research area.
