GCU Liveware Problem

The concept originated in the summer of 1966 as Yankee station was established for United States Task Force 77 aircraft carriers launching strikes against North Vietnam. A fixed patrol station within range of land-based aircraft made the stationed aircraft carriers vulnerable to attack. A PIRAZ station was established in the westernmost portion of the Gulf of Tonkin where air search RADAR coverage might extend over North Vietnam and the air-strike routes from Yankee station. This PIRAZ station radio call sign was "Red Crown."
