About the class
They are designed for anti-submarine warfare, anti-surface warfare, mine-laying missions, as well as reconnaissance and surveillance. This versatility makes them suitable for protecting naval bases, seashores, and sea lanes.
Their advanced capabilities enable them to operate in various environments, from the Arctic to more temperate climates, extending Russia's strategic reach and influence. The Lada-class submarines are well-suited for A2/AD strategies, where the goal is to deny an adversary access to certain critical regions.
