context_page_description: PIRAZ is a United States Navy acronym for Positive Identification Radar Advisory Zone. The zone is defined by the air search radar coverage of a ship patrolling a designated PIRAZ station. The concept was similar to radar picket stations established in World War II. The PIRAZ ship requires a Naval Tactical Data System radio-linked computer installation to effectively identify and track all aircraft anticipated to enter the airspace of the zone during combat.
