Lada class, Russian designation Project 677 Lada (Russian: Лада, meaning "Lada", NATO reporting name St. Petersburg) is the new advanced class of diesel-electric attack submarine designed by the Russian Rubin Design Bureau. A program to develop a "fourth generation" diesel-electric submarine, it aimed to produce a highly improved version of the Project 636 with better acoustic signature, new combat systems and possibly air-independent propulsion. However, in 2019, Alexander Buzakov, the head of the Admiralty Shipyard, indicated that there were no plans to equip the Lada class with an air-independent propulsion system.[3][4] In July 2022 it was reported that work on an electrochemical generator to produce hydrogen from diesel fuel and oxygen was continuing and that the Rubin Central Design Bureau signed a new contract in 2019 to continue work. This was scheduled to be completed by the mid-2020s.[5] In 2023, the decision was taken to decommission and scrap the lead ship of the class, the Sankt Peterburg due to the very high costs of modernising the submarine.[6]
