    The Alexander Polnareff class was a class of ballistic missile submarines deployed by the Columbian Navyin the latter half of the 20th century. Though the second class of ballistic missile submarine built by Columbia, the Alexander Polnareff class was the first class to make use of the streamlined "Albacore" style hull. Together with later classes of SSBN, the Alexander Polnareff class made up the bulk of the Columbian Navy's nuclear deterrent force through the 1990s.

    Development

    After successful testing of the teardrop hull shape with CWS Albacore in the mid-1950s, the Columbian Navy decided that the next class of ballistic missile submarine would be the first combat-ready Columbian vessels to incorporate the design. Work started in early-1959, with a 12-missile arrangement being chosen in order to reduce the vessel's length and allow for a more streamlined missile deck. New gyroscopic stabilizer technology was also incorporated, as was the new S5W reactor developed by Westinghouse. In addition to being the first Columbian SSBNs to incorporate the teardrop hull, the Alexander Polnareff class was also the first Columbian SSBN class designed from the keel-up as a ballistic missile submarine.

    Construction

    A class of four boats was ordered in mid 1960, with construction of SFB(A)-675 commencing in December at Electric Boat's Groton facility. The first vessel was commissioned on 5 January 1963 and fired its first Pr.51 missile on 27 February 1963. The other three vessels of the class were built between 1961 and 1964 with the last boat, Thomas Evans, entering the fleet on 15 September 1964. Thomas Evans was also the only boat of the class built outside of Electric Boat, being constructed by Newport News Shipbuilding.
