Construction started on October 4, 1989 at the Baltic Works in Leningrad (currently Saint Peterburg) but she was finally completed in the beginning of 2007, due to lack of funds. Upon completing sea trials the ship showed superior characteristics for an icebreaker, such as exceptional maneuverability and a top speed of 21.4 knots (39.6 km/h). The icebreaker based on project no. 10521 is an upgrade of the Arktika-class, the most powerful icebreakers ever built. The 159.60 m (524 ft) long and 20.0 m (66 ft) wide vessel, with a displacement of 25840 metric tons, is designed to break through ice up to 2.8 meters thick. She has a 140-man crew. 50 Led Pobedyis also an experimental project; for the first time in history of the Russian icebreakers it used a spoon-shaped bow. As predicted by the ship’s designers, such a shape increases the efficiency of the ship’s efforts in breaking the ice. The icebreaker is equipped with an all-new digital automated control system. The biological-radioactive shielding complex was heavily modernized and re-certified by the State Commission. A storage compartment for exausted radioactive materials was also created.
