History

San Juan was the first Los Angeles class (688-class) submarine to receive a number of significant improvements to the class's basic design, creating the 688I (for "improved 688"). San Juan and all following submarines in her class are quieter, incorporated an advanced AN/BSY-1 sonar suite combat system. The improvements also included the ability to lay mines from the torpedo tubes. The San Juan 's sail was also strengthened, enabling the ability to break through ice.[4]

First through ice surfacing

In 1993 the San Juan conducted the first through-ice surfacing for a 688i class submarine in the Arctic.[5]

Collision with USS Kentucky

On 19 March 1998 off the coast of Long Island, New York the submerged San Juan collided with the surfaced fleet ballistic missile submarine USS Kentucky (SSBN-737). There were no injuries reported with the collision.[6]

Lost communication

On 13 March 2007, San Juan was the subject of a search and rescue mission by elements of the Enterprise Carrier Strike Group when a red flare was spotted in her projected vicinity, suggesting an emergency. Communications were established by the early hours of the next day when San Juan surfaced, and no problems were indicated.[7]

Visit to South Africa

On 4 November 2009 the San Juan arrived at Simon's Town, South Africa. The ship engaged in at-sea maneuvers with the South African Navy for the first time in U.S. history.[8]
