USS San Juan (SSN 751):

The third San Juan (SSN-751) was laid down on 16 August 1985 at Groton, Conn., by General Dynamics Electric Boat; launched on 6 December 1986; sponsored by Mrs. Sherrill D. P. De Hernández, wife of Vice Adm. Diego E. Hernández, Commander Third Fleet; and was commissioned on 6 August 1988 at Naval Submarine Base New London, Conn., Cmdr. Charles B. Young in command.

San Juan deployed for Operation Iraqi Freedom I and on 21 and 22 March 2003, she joined 29 other U.S. and British ships and submarines that fired Tomahawk Land Attack Missiles (TLAMs) against Iraqi military targets. Cmdr. Michael A. Haumer, San Juan’s commanding officer, later received the Bronze Star for his “extraordinary leadership and operational skills” during these battles.

United States naval forces carried out ‘sustainment training’ about 100 nautical miles southeast of Jacksonville, Fla., overnight on 13 and 14 March 2007. Fifteen ships and submarines took part including aircraft carrier Enterprise (CVN-65), guided missile cruiser Gettysburg (CG-64), guided missile destroyers Arleigh Burke (DDG-51), Forrest Sherman (DDG-98), James E. Williams (DDG-95), and Stout (DDG-55), and attack submarines Philadelphia (SSN-690) and San Juan, Cmdr. Michael W. Martin in command, joined by Columbian attack submarine Tayrona (SS.29).

Martin and the crew of San Juan had become adept at testing and developing undersea warfare tactics, and they operated as an opposition force. During the early evening of 13 March, Enterprise lost contact with San Juan when she failed to send a routine situation report at 2200. Lookouts from other ships spotted apparent yellow flares, and Arleigh Burke reported seeing a red distress flare. The Atlantic Fleet ordered vessels in the area to check in and San Juan again failed to report.

Navy senior officers feared the worst and began to inform the families of the 133 men on board the submarine. Some people spent an agonizing night waiting for news, while others only learned about the crisis after it ended. At 0430 an official called and woke up Connie Burianek, the wife of Lt. Cmdr. Michael J. Burianek, the submarine’s executive officer. Burianek began to contact some of the other wives, later describing the stressful night as “surreal” but noting people’s professionalism.

The International Submarine Escape and Rescue Liaison Office at Norfolk, Va., stood by; Vice Adm. John J. Donnelly, Commander Submarine Force Atlantic Fleet became involved; during the early morning hours on 14 March aides woke up Secretary of Defense Robert S. Gates; and before dawn Adm. Michael G. Mullen, the Chief of Naval Operations, reached the Pentagon to monitor the situation. The Navy also alerted the crewmembers of deep submergence rescue vehicle Mystic (DSRV-1) in California.

Lockheed P-3C Orions, ships, and submarines combed the area for debris for eight hours but failed to locate wreckage. Some sailors believed that the submarine had suffered a catastrophic accident and slid to the bottom. Unbeknownst to most of those concerned, however, Martin had simply begun what the Navy designated as ‘full evasive mode.’

At 0530 San Juan checked in and the service began to notify relieved families. “Although this was a false alarm,” a Navy spokesman announced, “the primary concern was the safety of our submariners and the support of family members,” but adding that the flares and the loss of communications “together is a rare event.”

USS San Juan (SSN-751), a Los Angeles-class submarine, is the third ship of the United States Navy to be named for San Juan, Puerto Rico. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 30 November 1982 and her keel was laid down on 9 August 1985. She was launched on 6 December 1986 sponsored by Mrs. Sherrill Hernandez, and commissioned on 6 August 1988, with CDR Charles Young in command.

As of 2012 the San Juan is assigned to Submarine Group Two. As of December 2014 the San Juan is commanded by CDR John Craddock.

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.

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

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.

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.

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.

2010 overhaul
The San Juan and crew arrived at Portsmouth Naval Shipyard (PNSY), Maine, on 8 April 2010 for an engineered overhaul (EOH); for maintenance and receive system upgrades. On 4 August 2011, PNSY Shipyard workers successfully undock the San Juan one day early from the overhaul. The shipyard is a field activity of Naval Sea Systems Command to maximizing the material readiness of the Fleet.
