USS Baton Rouge: The LA Class That Collided With A Soviet Sierra-Class And Never Returned To Duty

USS Baton Rouge: The LA Class That Collided With A Soviet Sierra-Class And Never Returned To Duty

February 11, 1992. USS Baton Rouge (SSN-689), a Los Angeles-class fast attack submarine, was conducting covert intelligence operations twelve nautical miles north of Severomorsk—the Soviet Union's most heavily defended submarine base in the Barents Sea. Her mission was classified: service a seabed-mounted listening device that had been recording acoustic signatures from Russian Northern Fleet submarines for six months. The Cold War had officially ended just seven weeks earlier when the Soviet flag was lowered from the Kremlin on December 26, 1991. But in the frozen waters off the Kola Peninsula, nothing had changed. American submarines still prowled Russian naval bases. Russian submarines still patrolled with the same vigilance they had maintained for forty years. And at 8:16 PM local time, as Baton Rouge completed her intelligence mission and began withdrawing toward international waters, a nine-thousand-ton Russian Sierra-class submarine designated B-276 Kostroma surfaced directly beneath her. The collision lasted two seconds. The consequences would end Baton Rouge's career permanently.

Kostroma's titanium-reinforced sail struck Baton Rouge's aft section with catastrophic force, tearing through ballast tanks, rupturing hull plating, and creating stress fractures in welds that would never be fully repairable. Both submarines surfaced immediately—Baton Rouge listing fifteen degrees to port, unable to dive, her buoyancy control destroyed. Kostroma sustained superficial damage to her sail but remained operational. For the next five days, Baton Rouge limped across four hundred nautical miles of arctic water on the surface, exposed to Russian patrol aircraft, unable to submerge, relying on diplomatic assertions of international transit rights while damaged hull sections groaned under wave stress that could trigger catastrophic flooding at any moment. The submarine reached Norway on February 16, underwent emergency assessment, then made a twelve-day surface transit across the Atlantic to Connecticut. Structural analysis confirmed what the crew already knew: Baton Rouge was finished. The collision had compromised her pressure hull beyond economical repair. She would never dive again.
