Project 58 Grozny / Kynda class - Upgrades
Cruiser Project 58 served in the composition of all four fleets. They had not been subjected to major upgrades, but measures which mitigate against the ongoing aging process cannot be avoided. In the 1970s some of them established part of the undelivered at the time of radio engineering armament system "Success-In" ("Admiral Fokin" and "Terrible"), two-coordinate radar MR-300 replaced the PA Tristimulus MP-310 ("Admiral Fokin "and" Varyag "). In all ships, a second radar "Don 2" (detection of surface targets), gun salute, and, finally, two batteries of small-caliber six-barreled 30 mm AK-630 radar and fire control system "Vympel". Anti-aircraft missile B-600 were replaced by more advanced B-601, anti-4K-44 (on some ships) pa RCC "Progress".
Such a beginning was made with the Varyag, which had not been seen at sea for several years, but was again sighted in October 1981. The recognizable external modifications were, of themselves, not so extensive, except that they suggested a layover of several years in the yards. It must be presumed, therefore, that considerable work was completed which naturally cannot be detected from the outside, but rather concerned the ship's interior construction, as well as the main and auxiliary engines.
The outwardly recognizable modifications involved primarily the added superstructure. This consists of an extension of the bridge superstructure from the leading edge of the tower mast to just aft of the trailing edge of the forward funnel. In this area the side decks were built over. Thus sufficient room was gained to mount two six-barreled 30-mm automatic AA Gatling guns on each side to provide a defens againct SEA SKIMMER missiles. An associated BRASS TILT control radar was mounted on the substructure of the mast tower. Another modification involves the space between the two funnels, where a two-story deckhouse was placed. This could contain the data processing unit for some new command and control system. There are probably also additional electronics in the deckhouses on both sides of the aft tower mast. Also obvious was the replacement of the forward HEAD NET A radar with a HEAD NET C.
What was not modified -- and this observation must be based solely on the obvious external Indicators -- was the armament -- but above all not the missile systems, although they had not represented the state of the art for several years and could truly be considered obsolete. Perhaps the expense was too great for the Soviets, particularly, since the oncoming SOVREMENNYY and UDALOY destroyer classes were occupying yard space, and they appear to be under such severe pressure that perhaps they simply do not have any additional capacity.
In addition, on certain decisions in a number of cruisers established not provided by the project systems and systems: Jammer MP -262 ("fence"), a system of recognition of "Password", the complex of space navigation "Gateway", and so on. n. By the early 90s, these cruisers have already exceeded their age limit. In 1990, from the first was launched KTOF "Varyag", in 1991, came the turn of "Terrible" is composed DKBF, in 1993, the Navy wrote off the cruiser "Admiral Fokin" (KTOF).
