This is the impact zone for the payload fairing of the Soyuz-2.1v.

This is the first of an expected 18 military launches to be conducted by Russia this year. That number was given by Deputy Defense Minister Aleksei Krivoruchko on January 27. Sounds optimistic.

[Steven Pietrobon]

Russia has a large backlog of satellites due to past difficulty in obtaining electronic components. If these are now in hand, we should a expect a surge in launches at some point, which could be this year.

[Satori]

Any idea of what payload(s) might orbit?

[Galactic Penguin SST]

Any idea of what payload(s) might orbit?

I have no idea, but note that the NOTAM's drop zone has the exact same coordinates as the one used on the previous Soyuz-2.1v launch on December 27, so maybe it's the same kind heading to SSO?

Any idea of what payload(s) might orbit?

No, but it's worth noting that if the launch takes place right in the middle of the announced window (around 7.00 UTC) on February 9, the payload will end up in the same orbital plane as Kosmos-2574. After a month of inactivity, Kosmos-2574 began a series of minor burns on January 25 to slightly lower its orbit. But whether that has anything to do with the upcoming launch is impossible to say right now.

So far I see no nav warnings for the de-orbit burn of a Volga upper stage, so at the present time it would appear it will fly without the upper stage.

By the way, here is the complete set of nav warnings for the launch, both for the impact of the first stage and the payload fairing:

T-0 = 07:04 UTC per this insider.

TASS confirms launch took place at 7.03 UTC.

[sdsds]

Was Kosmos-2574 on 27 December 2023 the most recent prior launch of Soyuz-2.1v? Will this be Kosmos-2575? (One source says so.)

Also is the Tass report describing this as a 2.1b?

[Nicolas PILLET]

Was Kosmos-2574 on 27 December 2023 the most recent prior launch of Soyuz-2.1v?

Yes.

Will this be Kosmos-2575?

Probably.

(One source says so.)

RocketLaunch.live is not a 'source'.

Also is the Tass report describing this as a 2.1b?

No, the report says Soyuz-2.1v.

[B. Hendrickx]

TASS has now also confirmed successful orbit insertion.

The launch time is very close to the one that was required to make the satellite co-planar with Kosmos-2574 (and, coincidentally or not, the launch time is exactly the same as that of Kosmos-2574). Kosmos-2574 has been making further minor adjustments to its orbit in recent days, possibly in anticipation of today's launch. But we'll have to wait for the Two-Line Elements to see if there really is a link between the two satellites.   

[B. Hendrickx]

Two objects catalogued:

2024-027A  96.76° 348.8x361.1 km
2024-027B  96.76° 348.3x357.8 km

The initial orbit parameters of Object A are identical to those of Kosmos-2574 on December 27. The latter has since moved to a somewhat lower orbit (343x349 km). Virtually no doubt left now that there is a link between the two satellites.

Did I miss a launch?
Shouldn't this be 2024-026

Is it correct the RD-0110R used for vernier thrust is a single combustion chamber with four nozzles? Is there a plumbing diagram detailing the location of the combustion chamber and how the exhaust gets to the nozzles?

Four chambers, single turbopump assembly. I think these diagrams will help. The RD-0110R is named 14D24 here and the NK-33 is 14D15. The turbopump is indicated as "ТНА рулевого двигателя".
