Sonar technology comes to grips with dangerous new era

摘要

During the last five days of October 1962, U.S. Navy warships, guided by surface, sub-surface, and airborne anti-submarine warfare (ASW) sensor data, launched numerous practice depth charges at Soviet submarines violating the Cuban Missile Crisis blockade. The actions were in accordance with the "Submarine Surfacing and Identification Procedures" released earlier that month. ASW technology at the time included AN/SSQ-23 Julie, AN/SSQ-57B LOFAR (Low Frequency Acquisition and Ranging), and AN/SSQ-28 Jezebel sonobuoys, magnetic anomaly detection (MAD), radar, SQS-26 sonar, and SOSUS (Sound Surveillance System).
