Russia's small, stealthy "missiles-with-a-hull" corvette — an 860-ton Project 22800 ship that carries eight Kalibr or Oniks cruise missiles, the more seaworthy sibling of the Buyan-M. Cheap, heavily armed, and a recurring Ukrainian target.
Russia's Mach-2.5 ramjet cruise missile and the Bastion-P coastal batteries that fire it — designed to kill ships, but used relentlessly against Ukrainian land targets because its speed makes it brutally hard to intercept. The parent design of India's BrahMos.
Russia's small, shallow-draft Kalibr-armed missile corvette — a ~950-tonne hull that can transit inland rivers between fleets and lob land-attack cruise missiles 1,500 km. It fired the first combat Kalibr at Syria in 2015 and has been a principal platform for strikes on Ukraine.
Russia's most modern nuclear attack submarine — a multirole SSGN carrying Kalibr, Oniks, and Zircon cruise missiles in vertical silos, and the quietest Russian submarine design to date, assessed as comparable to US Seawolf/Virginia generation.
