Navy
The fleet arm — in this war defined by the Black Sea Fleet's losses to a navy without capital ships, and by Kalibr strikes from distant waters.
Broad area of activity
Four fleets and a flotilla; the Black Sea Fleet carries the war, with Kalibr shooters distributed across them.
Notable history
Its war is the Black Sea Fleet's war: Kalibr strikes on Ukraine from the sea since 2022, set against the progressive loss of surface units, basing and freedom of manoeuvre to a country without a fleet — the most studied naval story of the century so far.
Strengths
Kalibr strike reach from survivable submarine platforms; fleets outside the theatre remain untouched.
Limitations
Montreux closes the straits to reinforcement; Black Sea attrition is unrecoverable in-theatre; shipbuilding replaces losses slowly.
