Galactic Radiation and Background (nonfiction)

Galactic Radiation and Background (GRAB) was the covername for a series of five Project Dyno ELINT intelligence satellites, the first surveillance satellites operated by the U.S. Naval Research Laboratory (NRL) shortly after the Cold War U-2 incident of 1960. Though only two of the five satellites made it into orbit, they returned a wealth of information on Soviet air defense radar capabilities.
