BS-136 Orenburg (Delta III Stretch)
Submarineconfirmed
BS-136 Orenburg is a former Project 667BDR Kalmar (NATO: Delta III) ballistic-missile submarine that was rebuilt as a special-purpose "Delta Stretch" mothership for the GUGI deep-sea research directorate. Its missile compartment was removed and the hull lengthened so that it can carry deep-sea nuclear submersibles such as the Project 1851/18511 boats under its hull. It serves with the Northern Fleet in intelligence and special-operations roles. The original Delta III class is a large double-hulled nuclear-powered submarine 166 m long that displaces about 18,200 tons submerged.
