The class carries a formidable weapons load centered on the Kalibr land-attack cruise missile, which has a stated range of approximately 2,500 kilometers (1,553 miles) in its naval variant and has been used extensively against Ukrainian targets since 2022, along with the P-800 Oniks anti-ship missile and, in the most recent boats, the Zircon (sometimes written as Tsirkon) hypersonic cruise missile. The submarines are designed to hunt enemy surface ships and submarines, conduct long-range strikes against land targets, and gather intelligence, making them genuine multi-mission platforms rather than single-role weapons.
