I used JSR's orbital launch log as a reference.  It says 81/23, and has said this for many years.  We could all be wrong, of course!

Thanks Ed!

>>We could all be wrong, of course!
- If all three major internet reference sources are consistent - I better just follow them and not worry about being wrong :)

First launch pad was 81/24.

Second launch pad (81/23) was ready only in 1967. Kamanin writes about this in his diaries.

I failed to find launch pad names (in exact format) in Kamanin's diaries.
Indeed he writes about second launch pad being not ready as limiting factor (March 24, 1967)
and
he refers to them as "left start" (the first) and "right start" (the second constructed) - record of Sep 19, 1967.

So it's still curious where these names originate from, and whether  the first (left) pad has 81/23 or 81/24 designation.

Returning the thread to its earlier purpose, does anyone have the serial numbers of the 1 Proton rocket and Briz-M that flew in 2018 (April 18 with K-2526) by now?

Proton rockets №93559 and №93562 were both manufactured to launch GLONASS. Instead they were used to launch Blagovest satellites.

A question on pad names:
Anatoly Zak says the first pad for Protons was 81/24 with the first launch in 1965; and the second - 81/23 - went in operations in 1967.
However, databases by Ed Kyle and Gunter Krebs, they both have the opposite:
The first Proton was launched from 81/23 ; and pad 81/24 was the second.

Who's right?
I quote Anik's list
16.07.1965 Байконур 81/24

Latest Proton M rocket for MLM departed Moscow for the launch site on December 5th. Can someone please find out which phase is now being used and short and long serials??https://ria.ru/20181206/1547480277.html

Thanks - same article from RIA "sources say":   The third Blagovest satellite will be launched on 21 December 2018.   That will double the number of Proton missions in 2018.

Four sets (6 engines each) of RD-276 still make Proton-PM in Perm. That's it. The production ends in 2019.
Hard times for Proton-PM.  :(  The quality was excellent, the RD-276 always worked.
In 2020 starts the series production of RD-191. We will see how many of them are needed.

One thing I find difficult to get my head around, is that it looks like they make more than six engines for each Proton. The serial numbers give a clue, and it is known the same is done for Soyuz 11Д55 engine. You say quality is excellent, but wonder how many control samples fail?

Russian Military Standards require one engine to sustain complete destructive testing.   They will regularly build seven engines in a batch, then test fire one to destruction.   They then dissect the engine to confirm the failure of the components against the test criteria.   As of now, they run the engines at 112 percent thrust during a standard mission.  However, during testing, they may run the engines to 123-125 percent to confirm the performance margin.    This has been a standard requirement for many years within Russian launch vehicle industry.

For many years, no engine from Perm fails during a Proton launch.

- well
IF the serial numbers indeed indicate that some of manufactured units fail at acceptance test -
THAN it means that:
a. production line does have some issues;
AND at the same time
b. acceptance testing protocols are very rigorous and 100% effective - just because there were no flight failures/issues with RD-275.

And in the end of the day, is does not really matter who takes the 'quality prize' - production line or QC/QA.
IMHO, they both should get some credit for **The quality was excellent** assessment.

=========
According to my database, there were Proton failures associated with first stage engines - but early in the history.
The last ones with the tag "1-st st. engine failure" were
Aug 04, 1977 - Kosmos (937, 938) (TKS-VA #3, TKS-VA #4) - Proton-K
May 27, 1978 - Ekran (3a) (Ekran 13L) - Proton-K/Blok-DM
Jul 22, 1982 - Ekran (9a) (Ekran 23L) - Proton-K/Blok-DM

After 1982 there is no such tag for Protons.

Seeking confirmation or correction...
Currently scheduled 2019 Proton launches: ILS or government?
(Launch of MLM-U Nauka has apparently been delayed into early 2020.)

Satellite                               ILS/gov't?
Spektr-RG                             gov't
Yamal-601                            ILS
Eutelsat 5 West B & MEV-1     ILS
Blagovest #4                         gov't
Ekspress-80 & Ekspress-103   gov't
(the mysterious) Anik G2V      ILS?


https://ria.ru/20190111/1549210163.html
Google translation
Two commercial launches of the Proton rocket from Baikonur will take place in 2019

“In the first launch, the European telecommunications spacecraft Eutelsat 5 West B and the American technological satellite MEV-1 are scheduled to be put into orbit, and the second is the Russian telecommunications device Yamal-601,” the agency’s source corrected.

Yamal-601 is created by the European company Thales Alenia Space on the order of the Russian company Gazprom Space Systems. It will take a standing point of 49 degrees east longitude, in which it will replace the current Yamal-202.

<snip>
Two commercial launches are planned for Proton - a cluster one with communication satellites Eutelsat 5 West B and MEV-1 at the end of spring and with Anik G2V at the end of the year, the source said.

Yamal 601 is NOT an ILS mission.    They may be providing launch operations support in Baikonur, however the contract is between Gazprom and KhSC.

Anik G2V was never ordered - check Telesat Canada website.    There was discussions about ordering the next Anik G satellites, however Telesat has not order the satellite to be constructed, nor a launch contract with ILS on Proton.

Yamal-601 was not produced in Russia. So Khrunichev also needed to deal with ILS. The same situation was with Yamal-402. So it is ILS launch. For Roskosmos and Khrunichev it is a commercial launch.

Yes, none of the NSF contributors have found a reference to Anik G2V being contracted for, or being constructed.

(Fun fact: The Sun is spectrally classified in the MK system as G2V.)

Then why has RIA Novosti copied a Government presser say that it is launching in 2019?
