Is the Volga a redo of the original R-7 top stage?

No.

Volga is a lighter version of the venerable Ikar stage, which was used on some earlier Soyuz flights as an orbital maneuver stage (for Globalstar launches), but which is normally used as the service module for certain Russian military spacecraft. Ikar is basically the Samara knockoff of the Soyuz PAO, with many analogous components, and with very similar mass properties. Volga's dry mass is about 1/2 that of Ikar, but it has a similar propellant load.

I believe that some Russian military spacecraft will use the Volga bus instead of the Ikar bus.

I did not hear of the future use of Volga bus, but I would not be surprised if it happened. In Russia they say that a good tailor leaves no cut-offs.

I have information according to which Volga upper stage has a propulsion module called 14Д520.

14Д520 consists of :

   - Main engine 17Д64 (КТД - корректирующе-тормозной двигатель)
   - Correction engines С5.142 (ЖРДМТ - жидкостных рулевых двигателей малой тяги). There is 16 engines of this type, dispatched in two groups of eight engines.

There is a reference to a Soyuz-2-1VU rocket:-

In other news, does anybody here have the ignition sequence and a generic flight profile of the Soyuz-2-1v?

? Lighter?

First thing I found was from anatoly zak: http://www.russianspaceweb.com/volga.html
very bad dry to wet mass ratio.

That is not unusual for LEO-maneuvering pressure fed propulsion modules of this type, which don't need to provide substantial delta-v but which do need to serve multiple purposes while being rock solid reliable.  Cygnus and the HTV and ATV service modules, for example, probably have broadly similar, even worse, mass ratio properties.  Volga also seems to serve a dual purpose as a payload adapter, which would add dry mass.

Ikar was much worse.

This is to remind everyone that there is another launcher besides Antares that uses NK-33.

AND to also remind everyone that the joint American/Russian Project has lost more than a few engines during testing which resumed in 1994. There was also the first stage test article, which was destroyed during a firing on 16 August 2012 2013. The first test firing of a heritage NK-33 for Aerojet was on a test stand at Stennis in 1995. There were 5 series of test runs in 1995-1996 at Stennis.

Amended with correct date of last test failure on Russian soil.

First five Soyuz-2-1v are part of the trial launches. Prepared under contract №11/93?

The sixth Volga is instead be used with a Soyuz-2-1a for the launch of Lomonosov.

5 years ago, the first launch of the Soyuz 2.1v.
There were 4 launches, all successfully from the rocket side.
The faulty separation system of Kanopus-ST came from the satellite builder PO Polyot.
In 2019, the final test flight is planned.
What happens next? Are further launches planned?

5 years from the date of the first launch of the Soyuz-2 light class LV of stage 1c
December 28, 2018

December 28, 2018 marks 5 years since the day of the first successful launch of the launch vehicle of the light class "Soyuz-2" of stage 1c, developed and manufactured by Progressing RC.

The two-stage Soyuz-2 launcher of stage 1c is designed for launching spacecraft weighing up to 3 tons to a low near-earth orbit, and using the upper stage Volga to 1.4 tons - to a sun-synchronous orbit. This is the first light-class booster using liquid rocket engines, developed in modern Russia.

The launch vehicle Soyuz-2 of stage 1c was developed with maximum use of structural elements, on-board systems, production and technological base, and unified technical and launch complexes available for a Soyuz-2 type launch vehicle. This has significantly reduced the cost of developing, operating and launching the launch vehicle.

The booster is designed in a tandem pattern. The NK-33A engine (produced by PJSC Kuznetsov) and the RD0110R steering engine (developed by KBKHA and manufactured by the Voronezh Mechanical Plant) are installed on the central unit. To ensure the stability, controllability and operation of the Soyuz-2 control systems of stage 1c, a control system with a Soyuz-2 LV of stage 1b is used with the development of software and mathematical software and a change in instrumentation.

To provide an energetically optimal scheme for launching payloads to medium circular orbits, as well as to sun-synchronous orbits in conjunction with the Soyuz-2 stage of stage 1c, the Volga launch unit developed and manufactured by RCC Progress is used.

According to the results of the first launches as part of the flight design tests, a number of modifications were made to the Soyuz-2 launch vehicle of stage 1c. In particular, the volume of experimental measurements (pressure, temperature, vibration) on the blocks I, II of the LV and BV Volga was increased.

The flight test program provides for 5 launch campaigns. At the end of 2018, there were 4 launches of this media.

What happens next? Are further launches planned?

If they are able to return the money to Areojet for the engines earmarked originally Antares.  There is couple more engines. The plan is to exhaust the engine supply and switch to RD-191/RD-181 that's used for Angara & Antares now. Now the trade off between Angara 1.2 and Soyuez 2-1v. One has more pads then the other and is flying now.

Engines converted to AJ-26 have modifications that would not be economical to reverse and convert to the version used on Soyuz-2.1v. Instead RD-193 Will take over as the booster engine as well as a new steering engine assembly that is optimized for the booster stage. If Soyuz-2 series lifespan is extended the plan is to resume the upgrade of the strap on boosters to provide greater medium lift capabilities in the interim period. Soyuz-2.1A and B sub families variants would be retired and replaced by the interim version. Further commonality would reduce costs and other factors.
