The Kresta hulls lengthen and gain endurance as the series moves from four Kindas and four Kresta Is to ten Kresta IIs. Displacement rises, the machinery settles around a common 34-knot standard, and Kresta II's economical range grows markedly for sustained operations. Weapon emphasis also shifts from Kynda's heavier anti-ship fit toward larger air-defence magazines, Silex anti-submarine missiles, and 57 mm guns treated primarily as air-defence weapons. A new bow sonar and the Ka-25 helicopter extend the anti-submarine system beyond the hull. The comparison shows a family changing through linked adjustments in endurance, sensors, aircraft, and weapons rather than through one clean break.

How Kresta I became Kresta II
A close comparison shows the Kresta family growing in range, anti-aircraft armament, sonar, helicopter support, and missile layout rather than changing all at once.
