MLM not needed, as it uses the Britz?
Where are you getting all this from. I am yet to find a reference to use of a phase IV? The first list is from Mr. Krebs website and as far as I can tell was simply based on dates and assumption phase IV would be flying by now. And yes there is both an unaccounted Proton-K and Blok-DM, but the Proton-K would have passed its shelf-life by now? If I was to guess I'd say the next generation of Briz-M has already flown with Intelsat-22.

Initially there was just the enhanced Proton; documentation of that time makes no reference to a ‘phase’.The failure of the Proton-M with JCSat-11 lead to the closure of the 74·5° launch azimuth.It appears Phase IV is about regaining that lost capacity?

Stan I think is referring to the "74·5° launch azimuth" as 74·5° towards the equator, which was subsequently banned from future use by Kazakhstan officials. Russian officials had to accept the permanent ban of the 74·5° launch azimuth by Kazakh officials in order to resume launching from Baikonur Cosmodrome.

“Nominal Mission Lifetime” means, with respect to the Express AM4R Satellite, (based upon a Proton phase 4 performance) a period of 15 (fifteen) years after completion of the Final or Provisional Acceptance of the Satellite in orbit (whichever occurs first).

For Glonass or DM-03 upper stage, which Phase Proton is used?
Quote from: Danderman on 01/01/2014 10:11 pmFor Glonass or DM-03 upper stage, which Phase Proton is used?Up to now only the Proton-M phase I has been used with DM type upper stage. [further details]The latest missions feature the RD-276 on the first stage, in place of the RD-275. It is possible the RD-276 were not operated at full throttle. However Proton-M Briz-M (and also maybe Proton-K Briz-M) operated the RD-275 at a slight increase of 2%; so not sure what thrust they run at. [further details]It is also to be noted that some Proton-M phase I missions with DM upper stage, sported a white fairing. A white fairing made it’s appearance as part of the phase III upgrades, so are these DM fairings also with ‘improved energy-mass characteristics’?
