Here are some of the bigger cruiser projects the Soviets undertook during the 1960s. This began as a topic over at Warship Discussion 3.0. Me and Michael Rozon discussed these ships and this is the product of his research and educated guesses given the limited info available. I've added some of my own comments too and I hope this gets someone interested to perhaps find out more.
Project 1126
Project 1126 was intended to be an anti-aircraft escort cruiser for the Moskva Class with some surface-to-surface capability. The project ran through 1960-1961 in TSKB-17 with P. P. Milonov as head constructor. The ship was to be around 10,000 tons displacement, speed between 33 and 34 knots and a range of approximately 3500 miles at 24 knots. Twenty variants were examined during this period. They ranged in size from 6,200 tons up to 11,000 tons and speeds from 29.7 knots up to 35.5 knots. Steam turbine, Nuclear, gas turbines, Diesel and combined steam-and-gas turbines were investigated as propulsion arrangements.
The final choice is reflected below and was set down in July of 1960. This is the one reflected in the line drawing.
Dimensions: (Approx)
Length (oa) 196m
Maximum Beam 24.25m
Draught to Keel 5.36m
Displacement around 9000 tons
Power Plant: Probably two, but plausibly four, pressurised water nuclear reactors driving two 45,000 horsepower steam turbines driving two shafts.
Speed: estimated 32-33 knots
Armour: Probably none expect for some shielding around the reactor spaces.
Weapons:
Long-Range SAMs: Could have been either; 2 twin SM-68 or SM-69 twin launchers, 1 forward, 1 aft for the M-3 Naval SAM system firing the V-800 missile, with 10 missiles per launcher. The missile may have been command guided like the M-1 (SA-N-1) and M-2 (SA-N-2) with the ability to guide 2 or 3 missiles at the same target. The missile was sleek but with four disposable solid rocket boosters. Length was about 20m, range around 55km with a 195kg HE warhead. Guidance was to be provided by two “Fregat” missile fire control directors. Development for M-3 launcher and the V-800 missile was never completed.
Another version is 2 twin launchers for the M-31 Naval SAM firing a modified 2K11“Krug” (SA-4 Ganef) missile with ten rounds per launcher. This missile is a beam rider for mid-course control with semi-active radar homing in the terminal phase. One fire control radar could guide two missiles at the same target. These radars would be two modified Pat Hand missile fire control radars.
Medium-range SAMs: 2 twin launchers, 1 forward in the extreme bow, 1 aft just ahead of the stern helicopter platform, for the M-11 Shtorm Naval SAM using the V-611 missile (SA-N-3). There would have been 18-36 missiles per launcher. On the other hand the B-189 twin launcher which was fed from a two-storied missile magazine. Each story had four drums holding 6 missiles each used on the Moskva helicopter carrier might have been used in the final version or the 32 missile Zif-102 launcher and feed system used on the Kresta I Class. Of course the dual-role liited anti-ship capability could also be used to attack ships out to the radar horizon.
Guns: Four AK-725 twin 57-mm gun mounts. No 30mm or 37mm AA weapons included but if these ships had entered service I’m sure they would have added with associated radars.
Torpedoes: 2 triple 21-inch torpedo tube mounts. Possibly hull mounted as they are not in the deck plan. Two RBU-1000 rocket launchers also included for ASW defence. There is a landing pad for one Ka-25 but no hangar.
Electronics:
The primary systems intended for this ship not ready for it at the time the project was planned and the drawing shows the precursors to systems that eventually were found on Project 1123 (Moskva). Based on that, this what might have been the final suite. One MR-600 Voskhod (Top Sail) 3-D long range air surveillance radar, two MR-310 Angara (Head Net C) 3-D air and surface surveillance radars, two Don radars, the SAM guidance radars mentioned earlier, two MR-103 Bars (Muff Cob), ECM fit similar to Moskva and Kresta I and the MG-312 Titan and MG-311 Vychegda sonars in a retractable keel-mounted dome.
Project 63
There were several design variants investigated, including non-nuclear but in the end the bigger versions were chosen for further development. These ships would have dwarfed Project 1126. They were huge, well armoured and they were all heavily armed. Missile
The information table and the first two pages of drawings came from V.
Yakubov. The third drawing came from V. P. Kuzin's Taifun article on
Project 1144, the Kirov. Information form Shirokorad seems to apply to
the version in drawing number 3.
Here are the systems and armament for the final version which displaced 16 000 tons and had a speed of 32 knots.
Armament:
Anti-ship armament: Three retractable launcher for P-40 cruise missiles, two forward, one aft and each looks to be a trainable with either three or four tubes and a reload for each tubes was also carried giving around 18-24 missiles.
Long-Range SAMs: Two twin SM-68 launchers for the M-3 SAM using the V-800 missile, one forward, one aft. Ten missiles per launcher.
Medium-Range SAMs: two Zif-101 twin launchers for the M-1
Volna SAM system (SA-N-1), one on each beam for at least two x 8 missile drums for each twin launchers.
Guns: Four twin 76mm AK-726 mounts. Also two RBU-2500 antisubmarine rocket launchers mounted on the bows.
Electronics: Two Fregat SAM fire control radars, two Tenzor (Scoop Pair) fire control radars for P-40, two MR-300 Angara radars (Head Net A), two Razliv (High Lune) height finder radars, one port, one
Starboard one Taifun Long range air search radar, two MR-105 Turel (Owl Screech) gun fire control radar and two Yatagan (Peel Group) missile fire control radars for the M-1
Volna SAM system (SA-N-1).
A version designated Eh-4 was another large ship.

Beam - 22.5 metres
Draft - 7.84 metres
Machinery: one nuclear reactor supplying four turbines powering two shafts.
Speed: 32-33 knots
Armour: Much the same coverage as the Eh-4 but thicker armour used.
Armament:
Anti-Ship Missiles: Two P-20 strategic cruise missiles aft these are retracted out of the tube and then fired. Two quad SM-76 trainable missile launchers for P-40 anti-ship missiles, both forward.
Long-Range SAMs: two SM-68 twin launchers for the M-3 system, one forward and one aft with 10 missiles per launcher. Control provided by 2 Fregat radars.

Electronics: one Taifun, two MR-300 Angara (Head Net A), two Razliv (High Lune) height finder radars, three Tenzor radars (Scoop Pair) for controlling the P-40 missiles, four Krab (Top Hat), four Bizan (Watch Dog), two Nickel-Khrom systems, seven Kuznechik TV systems and two GAS-372 Gerkules sonars.
One of the conventionally powered versions was designated XN investigated.
Length - 179 metres
Beam - 19 metres
Draft - 5 metres to the keel, 7.2 metres to the bottom of the sonar dome in the lowered position.
Machinery: Oil-fired pressure-fired steam plant based on the KV-41 plant trialled in Project 41 destroyer Tallinn. Steam conditions 470 degrees C providing at least 100,000 horsepower.
Speed: 32 knots
Armour: No specifics but cruiser level protection equal to earlier versions.
Armament:
Anti-Ship Missiles: four twin two level fixed container launchers, two port and two starboard, for P-35 or P-40 anti-ship missiles. Eight missiles are in the upper levels ready for use. They would be elevated to a launch angle of about 20 degrees before firing. Eight reloads in the lower tier.
Medium-Range SAMs: two SM-68 twin launchers for the M-3 system, one forward and one aft with 10 missiles per launcher. Control provided by 2 Fregat radars. An alternative would be the M-2bis system (SA-N-2 Guideline) with Korvet (Fan Song E) radars.
Guns: four SM-62 twin mounts, either the 100-mm or 130-mm version, two forward and two aft, controlled by two Turel (Owl Screech) GFC radars, one on the forward superstructure and one on the aft face of the tripod mast. The SM-62 mount in both 100-mm and 130-mm versions had completed development and were ready for service entry on the last batch of Project 68bis cruisers (100-mm) and Project 56 destroyers (130-mm). Unfortunately, Khrushchev cancelled these ships.
ASW: two RBU-2500, side by side on the quarterdeck. Two triple 533mm torpedo tube mounts on the weather deck.

Armament:
Anti-Ship Missiles: three quintuple trainable launchers that appear to be fixed in elevation for P-40 or P-35 anti-ship missiles, two mounts forward, one aft. Possibly up to 15 reload missiles. Two cranes are situated on deck to bring reloads to the upper deck. This arrangement simplifies things greatly but makes reloading a time-consuming process.
Meduim-Range SAMs: four Zif-101 launchers for M-1 Volna (SA-N-1 Goa), two port and two starboard in the four corners of the ship, each launcher with 16 missiles. Control provided by two Yatagan (Peel Group) radars.
