USS Thomas Jefferson SSBN 618, USS John C Calhoun SSBN 630, HQ Afnorth, Oslo Norway

• USS Thomas Jefferson (SSBN-618): • First Polaris Patrol: USS Thomas Jefferson completed her first strategic deterrent patrol in 1964, carrying Polaris A-2 ballistic missiles as part of the United States’ nuclear triad during the Cold War. • Name Change: Originally commissioned as SSBN-618, the ship was later redesignated as SSN-618 in 1981 after being converted to an attack submarine and having her missile tubes deactivated. • Presidential Namesake: The submarine was named after Thomas Jefferson, the third President of the United States and principal author of the Declaration of Independence. • Dual Crew System: Like other ballistic missile submarines, Thomas Jefferson operated on a Blue and Gold crew rotation to maximize patrol time and readiness. • Deactivation and Recycling: The submarine was decommissioned in 1985 and scrapped in 1998 as part of the Navy’s Ship and Submarine Recycling Program in Bremerton, Washington. • USS John C. Calhoun (SSBN-630): • Namesake Controversy: The submarine was named after John C. Calhoun, the seventh Vice President of the United States, a prominent statesman and proponent of states’ rights and slavery, making her one of the more controversial namesakes in Navy history. • Polaris to Poseidon: She was originally equipped with Polaris missiles, later converted to carry the more advanced Poseidon C3 ballistic missiles, increasing her deterrence capability. • Strategic Deterrence: USS John C. Calhoun performed more than 70 strategic deterrent patrols during her service from 1964 until her decommissioning in 1994, making her one of the longest-serving “41 For Freedom” boats. • Unusual Nickname: The crew often referred to the boat as “Big John” or “Calhoun’s Crew” during her decades of service. • HQ AFNORTH (Allied Forces Northern Europe), Oslo, Norway: • Cold War Headquarters: HQ AFNORTH was the NATO command responsible for the defense of northern Europe, including Norway, Denmark, and northern Germany during the Cold War. • Location and Bunker: The headquarters was located in Kolsås, just outside Oslo, in a massive underground bunker designed to withstand nuclear attack and ensure command continuity in crisis. • Multinational Staff: The staff at HQ AFNORTH was multinational, with officers from several NATO member nations working together to plan and coordinate defense efforts in the region. • Disbanded in 1993: Following the end of the Cold War and NATO restructuring, HQ AFNORTH was deactivated in 1993, marking the end of an era in northern European defense. • Historic Legacy: The site of HQ AFNORTH remains a symbol of Norway’s and NATO’s commitment to collective defense, and the Kolsås bunker is now used for other military purposes.
