During the early evening of 13 March 2007, units of the USS Enterprise Carrier Strike Group (CSG) received a series of indications that USS San Juan (SSN-751), a Los Angeles-class submarine conducting pre-deployment training with the Enterprise CSG, was in distress.[6]
The submarine established communications in the early morning hours of 14 March, and indicated that there were no problems; hence, units were able to stand down from the search and rescue that was already well underway.[6]
San Juan was the first of the Flight III or 688i for "improved" design, that received a number of significant improvements to the previous boats in the class. San Juan and all subsequent boats in her class are quieter and incorporate an advanced AN/BSY-1 sonar suite combat system. Another improvement includes the ability to lay mines from their torpedo tubes. San Juan's sail was also strengthened, enabling the ability to break through ice.[7]
In 1993 San Juan conducted the first through-ice surfacing for a 688i-class submarine in the Arctic.[8]
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 as a result of the collision.[9]

On 13 March 2007, San Juan was the subject of a search and rescue mission by the carrier USS Enterprise and elements of her Carrier Strike Group off the coast of Florida, when contact with the submarine was lost, and a red flare was spotted in her projected vicinity, suggesting an emergency. Communications were re-established early the next day when San Juan surfaced, and no problems were indicated.[10]
On 4 November 2009 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.[11]

San Juan arrived at Portsmouth Naval Shipyard (PNSY), Maine, on 8 April 2010 for an engineered overhaul (EOH); for maintenance and system upgrades.[12]
As of 2012 San Juan was assigned to Submarine Group Two. Submarine Group Two was disestablished in 2014, and San Juan became part of Submarine Force, U.S. Atlantic Fleet (COMSUBLANT).
