The NextSpaceFlight website states that the Neitron #1 is now scheduled for launch in September of this year.

FWIW, as of this post, same source lists NET November.

According to the same source, the Neitron satellite is listed as being planned for launch NET June 2022.

TASS reports that a Soyuz-2 launch is scheduled from Plesetsk on 3 February. One of the impact zones will be near Yar-Sale in Western Siberia. This was also an impact zone for launches of the Lotos and Pion electronic intelligence satellites into 67° inclination orbits. My best guess is that the payload will be 14F145 (Lotos) nr. 806, the first of a batch of four new Lotos satellites ordered by the Ministry of Defense in September 2017. There are no signs in available documentation that a second Pion satellite was manufactured apart from the one that was launched last June.

We also shouldn't exclude the possibility that the payload is the long-delayed Neitron. It is unknown into what kind of orbit this will be placed.

A usually reliable inside source on the NK forum says the payload is 14F01 and the launch vehicle is the Soyuz-2.1b/Fregat. 14F01 is an index that has been associated in documents with satellites named Neitron and Tekhnolog. Indications are that these are two different satellites developed by NPO Mashinostroyeniya that are part of the same project. They are likely to be launched separately. It is not clear which of the two is going up next week.

The 2017 procurement plan of the Progress Rocket and Space Center as well as a newsletter published by NPO Lavochkin in 2018 linked the project to the Soyuz-2-1a. This would indicate that a decision was made only recently to switch to the 2-1b variant. Another possibility is that one satellite will be launched by 2-1a and the other by 2-1b.

Although some information is available on subcontractors, individual systems and ground support equipment, the exact purpose of the project remains a mystery. The orbit parameters observed after the launch may shed some light on that. The reported drop zone suggests the launch vehicle will follow the same trajectory as that used for the launch of the Liana and Pion ELINT satellites, which points to a 67° inclination orbit (unless some sort of dogleg maneuver is made during the launch). The Fregat upper stage could place the satellite into a relatively high orbit. There are some indications that the satellite(s) will use the same bus as the Kondor radar imaging satellites (weighing about 1 tons) and will operate in a challenging radiation environment.

Assuming the inside information is accurate, this thread can be merged with the already existing Neitron launch thread:

According to updated information from the insider, the launch vehicle is the Soyuz-2.1a after all. The scheduled liftoff time is 10.00 Moscow time (7.00 UTC), both on February 3 and the back-up date (February 4).

From the "Voyenno-boltovoi" telegram channel: the trajectory that the Soyuz-2-1a rocket will follow based on NOTAM coordinates. It is virtually identical to that of Lotos/Pion launches into a 67.1° inclination orbit. The circle denotes the core stage impact zone in the Yamalo-Nenetsk Autonomous Region.

Interfax-AVN reports the Fregat separated from the third stage at 10.09 Moscow time and that insertion by the Fregat into the final orbit will take several hours.
