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 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.
The Sa'ar 6 Magen class consists of four multi-mission corvettes built for the Israeli Navy to defend offshore gas fields and shipping lanes, armed with Barak-8 area-defense missiles and the shipborne C-Dome point-defense system, and recently employed in long-range strikes against the Houthis.
Russia's principal modern multirole corvette family — compact littoral combatants evolved from a simple anti-surface/ASW design into a Kalibr-carrying strike platform, forming the coastal backbone of the Baltic, Northern, and Pacific Fleets.
