North Warning System

The North Warning System (NWS) is a joint United States and Canadian radar system for the atmospheric air defense of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region. It replaced the Distant Early Warning Line system in the late 1980s.

Famous quotes containing the words north, warning and/or system:

    We have heard all of our lives how, after the Civil War was over, the South went back to straighten itself out and make a living again. It was for many years a voiceless part of the government. The balance of power moved away from it—to the north and the east. The problems of the north and the east became the big problem of the country and nobody paid much attention to the economic unbalance the South had left as its only choice.
    Lyndon Baines Johnson (1908–1973)

    What I am now warning the People of is, That the News-Papers of this Island are as pernicious to weak Heads in England as ever Books of Chivalry to Spain; and therefore shall do all that in me lies, with the utmost Care and Vigilance imaginable, to prevent these growing Evils.
    Richard Steele (1672–1729)

    While the system of holding people in hostage is as old as the oldest war, a fresher note is introduced when a tyrannic state is at war with its own subjects and may hold any citizen in hostage with no law to restrain it.
    Vladimir Nabokov (1899–1977)
