Udaloy-class anti-submarine destroyer Key Events

  1. Project 1155 is conceived as a specialist ASW ship

    Soviet designers developed Project 1155 as a dedicated anti-submarine surface combatant after concluding that large multi-role ships were too costly.

  2. The first Udaloy-class ship enters commission

    Wikipedia records the class as entering commission in 1980, beginning the long service life of the first Project 1155 ships.
