The NATO lists the class as "cruisers" mainly due to the Metel (SS-N-14 Silex) anti-ship missile system capable to strike not only submarines but also surface vessels.
Conway's states that the first three ships were to have been armed with the SS-N-9 anti-ship missile but Soviet naval doctrine changed with greater emphasis on anti-submarine warfare.
The machinery suite comprised two TV-12 steam turbines with high-pressure boilers, identical to the Kresta I class.
[1] Kresta II-class vessels were propelled by two TV-12 steam geared turbines powered by four high pressure boilers which created 75,000 kilowatts (101,000 hp).
The first four ships of the class to be completed were not equipped with the MR-123 Vympel fire control radar for the AK-630, and relied on manual targeting instead.
