Soyuz-2-1B – Kosmos (Lotos-S № 4) – ?

I am assuming that’s not a completely accurate image. TBH I am amazed that any kind of image has been released.

The SC Bus has also been used by Civilian programmes. The payload portion of the  model is based on this image released by TsNIRTI: http://russianspaceweb.com/images/spacecraft/military/elint/liana/lotos_payload_2.jpg
The image above on his site is a scale model of a Lotos-M (should be S) spacecraft. There are 2 Lotos-S ELINT payload configurations: one with Nuklon onboard and one without Nuklon. Liana system consists of Pion-NKS sea based ELINT with Radar and Lotos-S land based ELINT sats.

Is it speculated if any spacecraft now use large deployable mesh antennas, as wasn’t this something that it’s believed that US models had but Russian didn’t?

only Pion-NKS are known to use Russian style deployable mesh antennas of a design dating back to before the launch of MIR's Priroda module (77KSI).

Russianspaceweb.com lists this satellite to launch from Plesetsk 43/4 on October 19.
http://russianspaceweb.com/2018.html

If all goes as (apparently) planned, it will be the next orbital launch from Plesetsk, and the next Soyuz launch from Plesetsk, and become Kosmos 2528.

Russian Space Web also has this flight as Soyuz's return to flight.

October 25: A Soyuz-2 rocket to launch a 14F145 electronic intelligence satellite for the Russian military from Pad 4 at Site 43 in Plesetsk. The launch was initially planned for August 26, 2018, but on August 17, the decision was made to postpone the mission even though all preparations at the launch site were proceeding as planned, indicating a possible issue with a previous spacecraft in orbit. At the beginning of October, the launch was planned for October 18, but by the middle of the month, the mission was re-scheduled for October 25, in the wake of the launch accident with the Soyuz MS-10 spacecraft on October 11.

Cross-post; apparently this launch will proceed before the final report is released on the launch failure of Soyuz MS-10:

Roscosmos. Meeting of the emergency commission
10/20/2018 4:53 pm

A regular meeting of the emergency commission on an emergency situation that occurred on October 11, 2018 during the launch of the Soyuz-FG launch vehicle with a manned transport vehicle Soyuz MS-10 was held at the leading research institute of the rocket and space industry of Russia - TsNImash.
After listening to the reports of specialists working on the investigation of the causes of the emergency situation, the members of the emergency commission, after a detailed analysis, approved a preliminary report on the causes of the accident and began to prepare recommendations to exclude similar situations in the future. The final report and the list of recommendations to the enterprises of the rocket and space industry will be approved on October 30, 2018 and presented to the chairman of the State Commission for Flight Testing of Manned Space Systems.

"The areas for aviation are closed from 01:00 to 06:00 Moscow time on October 25 under the launch of Soyuz-2 from Plesetsk with a military satellite. This will be the first launch of the Soyuz rocket after the Baikonur accident," a source said.

Previous Lotos launch dates/times (all launches on Soyuz LV's from Plesetsk):

Kosmos 2455     11/20/2009, 10:44 UTC
Kosmos 2503     12/25/2014, 03:01 UTC
Kosmos 2524     12/02/2017, 10:43 UTC

Is there a pattern developing that indicates a replacement satellite, or will this be an addition to a pattern by adding a new element to a satellite constellation?

AFAIK it is the same generation and is in addition to previous sats. Kosmos 2455 was a prototype sat and this launch will place the next operational sat in the constellation. I expect Kosmos 2455 will be retired on the next launch after handover period.

Cosmos 2455 appears to have stopped doing orbital manoeuvres and began slow orbital decay when Cosmos 2503 was launched.
