Confirmation from Russian observers:

"Только что видел как ракета летела с плесецка возможно, что за запуск?"

It says that the launcher has successfully lifted-off. It's very too early to qualify this launch as successful.

Orbit has been achieved. It will take "several hours" to reach the target orbit.

I note that the satellite isn't named and also that the launch time has been "chopped", rather than being rounded to 20h 39m Moscow Time.

These pictures show Angara-A5 launch in 2014 and second Soyuz-2.1v launch in 2015.

Congratulations to Spaceflightfans.cn for putting their mark on pictures that do not belong to them and that do not show today launch.

Interfax-AVN now quoting the press service of the Ministry of Defense as saying that the satellite reached its target orbit at the intended time. Steady telemetry being received, on-board systems functioning normally. The satellite has been named Kosmos-2525.

Object A cataloged at epoch 19:27 UTC

2018-028A in 316 x 319 km x 96.64°

Seems to correspond to SSO according to https://smallsats.org/2013/04/11/sun-synchronous-circular-orbit/

We also have Object B (Stage II?)

I am guessing that this might be Volga, with the second stage (still called Blok I?) in a lower, more eccentric orbit. Compare with the Cosmos 2519 launch.

Yes.

There was no Volga on this launch.

The Antares rocket was backed out of using a modified NK-33. Issues during test firings and the in-flight failure were blamed by Russia on the Aerojet modifications. From the list of Aerojet changes, their assertion doesn't seem very plausible. Any insights on how the Russians really discounted the failure potential?

Interesting...another piece of evidence to deduce the payload was relatively light, light enough to be placed in SSO with no Volga upper stage?

Also, another data point of successful use of the NK-33.
