The [[National Severe Storms Laboratory]] has been using a SPY-1A phased array antenna, provided by the US Navy, for weather research at its [[Norman, Oklahoma]] facility since April 23, 2003. It is hoped that research will lead to a better understanding of thunderstorms and tornadoes, eventually leading to increased warning times and enhanced prediction of tornadoes. Current project participants include the National Severe Storms Laboratory and National Weather Service Radar Operations Center, [[Lockheed Martin]], [[United States Navy]], [[University of Oklahoma]] School of Meteorology, School of Electrical and Computer Engineering, and [[Atmospheric Radar Research Center]], Oklahoma State Regents for Higher Education, the [[Federal Aviation Administration]], and Basic Commerce and Industries. The project includes [[research and development]], future [[technology transfer]] and potential deployment of the system throughout the United States. It is expected to take 10 to 15 years to complete and initial construction was approximately $25 million.<ref>[[National Oceanic and Atmospheric Administration]].
