Anatoly Zak reports that a Soyuz-2 is to launch a military payload from Plesetsk on June 25.

Meanwhile, a Plesetsk insider gave a hint on the "Novosti kosmonavtiki' forum today that the launch of the long-delayed Pion is imminent, so this this looks like the payload for this mission.

TASS confirms that a military Soyuz launch is planned from Plesetsk on June 25. Back-up dates are June 26, 27, 28, 29 and 30. One of the drop zones is in the north of the Komi republic, which is consistent with a launch into a 67° inclination orbit that would be expected for Pion (same inclination as the Lotos satellites that are also part of the Liana constellation).

The launcher should be on the launch pad.

According to the Plesetsk insider on the NK forum, the launch is scheduled for 22.50 Moscow time (19:50 UTC). He  confirms that the payload is 14F139 (=Pion). Weather outlook is good.

To use the Kosmos moniker?

The Lotos satellites got "Cosmos" designation.

A couple of posts on the NK forum suggest liftoff has taken place. Apparently long-distance observations, not from Plesetsk itself.  End of a 28-year countdown for Pion, initially approved in 1993...

Moscow. June 25. INTERFAX - A combat crew of the Space Forces of the Aerospace Forces has successfully launched a Soyuz-2.1b carrier rocket from the Plesetsk cosmodrome, the Department of Information and Mass Communications of the Russian Defense Ministry reported.
       "On Friday, June 25, at 22:50 Moscow time, from the launcher (PU) No. 4 of the site No. 43 of the State Test Cosmodrome of the Ministry of Defense of the Russian Federation (Plesetsk Cosmodrome) in the Arkhangelsk Region, the combat crew of the Space Forces of the Aerospace Forces launched a launch vehicle "Soyuz-2.1b" with a new generation spacecraft in the interests of the Russian Ministry of Defense ", - noted in the military department.
       As specified in the Ministry of Defense, all prelaunch operations and the launch of the Soyuz-2.1b space rocket took place in the normal mode. "The ground assets of the Space Forces of the Aerospace Forces monitored the launch and flight of the carrier rocket," the ministry added.
       This is the second launch of the Soyuz-2 medium-class launch vehicle from the Plesetsk cosmodrome in 2021. The previous one was successfully carried out from the northern cosmodrome on February 2, 2021.
       Flight tests of the Soyuz-2 space rocket complex began at the Plesetsk cosmodrome on November 8, 2004. Over the past sixteen years, 46 launches of medium-class Soyuz-2 carrier rockets 1A and 1B, as well as 6 launches of Soyuz-2 carrier rockets of light class of modernization stage 1 V.

Announced as Kosmos-2550.

First amateur videos of the launch showing up on YouTube. This was taken from Kirov, about 700 km southeast of Plesetsk.

It's in a much lower orbit than the Lotos satellites, which circle the Earth at an altitude of about 900 km. This must be to allow the radar to obtain the best possible images. There was a somewhat similar pattern in the Soviet-era Legenda ocean surveillance system: the "active" nuclear-powered radar observation satellites (US-A) and the "passive" electronic ocean intelligence satellites (US-P) had the same inclination, but the US-A satellites flew at a mean altitude of 255 km and the US-P satellites at a mean altitude of 435 km. It will be interesting to see if there is any correlation between the orbits of Pion and the still active Lotos satellites to ensure maximum coverage.
