The attacks of September 11, 2001, prompted calls for large increases in government spending on counterterrorism research. Apparently, Congress and the Bush administration were listening. The three agencies listed here are slated for the biggest boosts in research and development funding in fiscal year 2003, with much of the new money going toward better technology for thwarting and responding to terrorist attacks.

Of the three, the Department of Defense comes out on top. It will see an additional $9.1 billion appropriated for R&D over last year's $49.6 billion. The 18.4 percent increase is the largest the department has ever seen.
