The SS El Faro was a U.S.-flagged cargo ship with a distinctive design as a combination roll-on/roll-off and lift-on/lift-off vessel, primarily crewed by American merchant mariners. Built in 1975 by Sun Shipbuilding & Drydock Co. in Chester, Pennsylvania, she initially bore the name Puerto Rico and was operated by the Navieras de Puerto Rico Steamship Company. In 1991, she was renamed Northern Lights after being acquired by Saltchuk Resources, and in 2006, she received her final name, El Faro, under TOTE Maritime. As constructed, El Faro measured approximately 790 feet (240 meters) in length and was equipped to carry cargo containers, trailers, and vehicles. She underwent significant modifications during her service life: in 1992, a 90-foot mid-body extension added cargo holds and a spar deck; between 2005 and 2006, further upgrades included installing lift-on/lift-off cranes, adding ballast, and raising her load line to enhance cargo capacity. Despite these modifications, concerns about stability and seaworthiness persisted, especially as she was known to suffer drainage issues and deck holes prior to her sinking. El Faro served both commercial and military purposes. She operated along the U.S. East Coast and between Tacoma and Anchorage, but notably, she was chartered by the Military Sealift Command in 2003 for Operation Iraqi Freedom, transporting Marines and military equipment to Kuwait. She participated in 25 voyages, carrying over 12,200 pieces of military equipment, and was praised for her service in this role. Her final voyage began on September 29, 2015, from Jacksonville, Florida, heading toward San Juan, Puerto Rico, with a cargo of containers, trailers, and vehicles, and a crew of 33. Despite weather warnings, she departed into the path of Hurricane Joaquin. During the voyage, the ship encountered severe storm conditions, including heavy swells and high winds, and ultimately suffered from flooding, loss of propulsion, and a significant list. Communications ceased early on October 1, 2015, and she was declared lost at sea after extensive search efforts, which recovered debris and identified her wreck in late October at a depth of approximately 15,000 feet (4,600 meters). El Faro's sinking is a notable maritime tragedy, highlighting issues of storm navigation, vessel maintenance, and safety management, and she remains a symbol of the risks faced by merchant mariners in severe weather conditions.
