And this is the most recent news that I could find in the Vostochny Cosmodrome updates thread:
https://forum.nasaspaceflight.com/index.php?topic=19909.msg2318344#msg2318344

The work is apparently done.  The wait to use it appears to be because of payload delays?

In this case, Russian use Fregat = Fregat-M?  Or MT?

Fregat-MT so far has only flown out of CSG whereas Luna-25 was originallyplanned to use one.

Condensed Summary History:
Fregat/Flagman was developed as the Proton 5th stage as both a Mars cruise stage for Soviet and Russian Mars missions using the Proton-K/Blok-DM2/DM-3 or the later Proton-M/Blok-DM-03 which would have flown Phobos-Grunt-2 (1R) as well as a direct GEO/multiple orbit upper stage. The Flagman upper stage was a parallel project. Fregat-MT and Fregat-2 with Blok-D derived toroidal tank formed to basis for Fregat SB. The entire Fregat family's upcoming next generation replacement version is Fregat-SBU and the family's derivative used by the PTK optionally manned spacecraft family's propulsion system tank design. Fregat-SBU is designed to fly standalone on Angara-A3/A5. Soyuz-5/6/7 or on top in a dual upper stage configuration with Blok-DM-03 and the Persei versions.

Three #GonetsM satellites (No. 33, 34 and 35) were delivered to #Vostochny to be launched on Soyuz 2.1b with a secondary payload on October 22. It will be the first and only launch from Vostochny this year. The other 5 of 6 scheduled launches were postponed to 2023 (guess why).

On Friday, September 30, 2022, the Progress Rocket and Space Center (part of Roskosmos State Corporation) hosted a meeting of the board of chief designers on the completion of flight and design tests of the Soyuz-2 space rocket complex at the Vostochny cosmodrome and its transition to offset tests, as well as readiness to launch the Soyuz-2.1b launch vehicle with the Fregat upper stage from Vostochny in fall 2022 for the first time entirely on new fuel.

The meeting was chaired by RSC Progress General Director Dmitry Baranov and Executive Director for Launch Facilities and Ground-Based Space Infrastructure Operation of Roskosmos State Corporation Andrei Mazurin.

Sergei Volkov, deputy general designer of RSC Progress launch vehicles, reported on implementation of the program of flight tests of the Soyuz-2 complex from the Vostochny launch site, as well as on the readiness of the Soyuz-2.1b rocket to launch three Gonets-M spacecraft and the Skif-D demonstration satellite.

Participants in the meeting confirmed the readiness of the Soyuz-2 complex at Vostochny for flight tests entirely on naphthyl fuel.

Vostochny cosmodrome specialists assembled the space head module for the upcoming launch of four spacecraft - the first Sphere project satellite, named Skif-D, and three Gonets-M communications satellites.

 

The satellites went through a full training cycle at the Technical Complex of the Cosmodrome and were then allowed to dock with the upper stage. After the docking, the head fairing was rolled onto the Fregat upper stage with the Gonets-M and Skif-D spacecraft.

Roskosmos confirmed the launch date of the Soyuz rocket from Vostochny.

Roskosmos announced that the launch of the Soyuz-2.1b rocket from Vostochny is scheduled for October 22.

14:48 10/17/2022

MOSCOW, October 17 - RIA Novosti. Roskosmos confirmed that the next launch of the Soyuz-2.1b rocket from the Vostochny cosmodrome is scheduled for October 22.

Earlier, the press service of the Yakut head office of the Ministry of Emergency Situations of Russia reported that on October 23 at 4.57 local time (22.57 Moscow time on October 22), the first satellite of the Sphere group, Skif-D, will be launched on the Soyuz-2.1b rocket. Together with the apparatus, three Gonets-M communication satellites will be launched into orbit.

Roskosmos CEO Yury Borisov checked the readiness of the control system for the Soyuz-2.1b launch vehicle using a new type of fuel, naphthyl.

It is noted that at the Research and Production Association of Automation named after Academician N. A. Semikhatov in Yekaterinburg , Borisov visited the workshops for the production of radio-electronic equipment for rockets of the Soyuz-2 family. Andrey Misyura, director general of NPO Avtomatika, said that in order to work on the new fuel pair, the software and algorithmic support of the equipment for the control system of the launch vehicle and the launch complex of the Vostochny cosmodrome had to be finalized.

Roscosmos recalled that the last launch of Soyuz-2 from Vostochny on kerosene with oxygen was carried out in October 2021. Previously, they had already run the third stage of Soyuz-2.1b. The upcoming launch will be the first when all stages of the rocket will be filled with naphthyl. The advantage of naphthyl is the reduction of harmful emissions and an increase in the mass of the payload thrown into orbit.

 On Tuesday, October 18, 2022, at the Vostochny Cosmodrome, specialists from Roskosmos State Corporation companies performed general assembly of the Soyuz-2.1b space rocket with three Gonets-M satellites and the first vehicle of the federal Sphere project, Skif-D.

The state commission then issued a conclusion about the rocket's readiness to be removed and installed on the launch pad 1C on Wednesday, Oct. 19, 2022.

The launch of four spacecraft by the Soyuz-2.1b launch vehicle with the Fregat upper stage is scheduled for Oct. 22, 2022, at 22:57 Moscow time.

The Soyuz-2.1b launch vehicle was built by the Progress Rocket and Space Center, the Fregat upper stage by the Lavochkin Science and Production Association, and the satellites by the Reshetnev Information Satellite Systems company (part of Roskosmos).

This will be the first launch of the Soyuz-2 carrier rocket entirely using a new and highly environmentally friendly fuel - naphthite. Previously, only the third stage of Soyuz-2.1b rocket and the second stage of Soyuz-2.1v were fueled with it. The last Soyuz-2 from Vostochny, with the first and second stages fueled with kerosene, was launched in October 2021. Naphthyl is an environmentally safe type of hydrocarbon fuel using polymeric additives. Its advantages are reduction of harmful emissions and a noticeable increase in payloads that can be launched into orbit. One of the main reasons for switching from kerosene to naphthyl was the depletion of the Anastasievsko-Troitskoye field in the Krasnodar Territory.

Low-orbit Gonets-M spacecraft are designed to transmit data and provide mobile satellite communications services to mobile and stationary subscribers anywhere on Earth. Since 2005, 22 Gonets-M satellites have been put into orbit. In 2015, the Gonets-D1M multifunction personal satellite communications system with Gonets-M satellites was put into operation. The system operator is Gonets Satellite System (part of Roscosmos).

Demonstration satellite "Skif-D" is assigned for testing new technical solutions for high speed internet access and protection of the orbital frequency resource. It is the first vehicle of the Sphere federal project, which will include five satellite communications constellations (Yamal, Express-RV, Express, Skif and Marathon) and five Earth remote sensing satellite constellations (Berkut-X, Berkut-O, Berkut-VD, Berkut-S and Smotr)

So, it's just "Fregat"?

On Wednesday, October 19, 2022, a Soyuz-2.1b rocket carrying three Gonets-M satellites and the first vehicle of the federal Sphere project, Skif-D, was transported to the launch pad 1S of the Vostochny cosmodrome.

I thought 14F149 was Blagovest  ???

B. Hendrickx said that in 2018 (Kosmos 2519/2521/2523 launch thread) :
Quote
The second OZS is said to be part of “Object 61/2B”, which is a facility belonging to ISS Reshetnev in Krasnoyarsk. Strangely enough, the manufacturer of this OSZ is given as “OOO Firma Spektr”. Object 61/2B appears in various contracts, one related to in-flight tests of the 14F149 Blagovest military comsat.
