Russians consider building another new rocket
The competition heats up? The Russian government is considering building another new rocket that would be based more on Proton than Angara and could function eventually as the foundation for a heavy-lift rocket.
At the heart of the new design was the idea to enlarge the diameter of the Zenit rocket from 3.8 to 4.1 meters, so it could match the “caliber” of the Proton rocket. As a result, the Proton’s production machinery could be re-used with relatively few upgrades to manufacture the new-generation launcher, after its predecessor’s planned retirement in mid-2020s. Unlike Proton, all stages on Sunkar would burn non-toxic kerosene and liquid oxygen, as it had long been insisted upon by the Kazakh government. The Sunkar could utilize the existing launch and processing infrastructure for the Zenit rocket in Baikonur, which could be funded by Kazakhstan.
…Ironically, the proposal to develop yet another type of space launcher essentially reverses the previous strategy at GKNPTs Khrunichev of relying on a modular architecture of the Angara family to cover the entire spectrum of space payloads. However, unlike Angara’s standard booster, URM-1, the first stage of the Sunkar rocket will be large enough to serve as a building block for a future super-heavy rocket, reaching payloads of at least 80 tons, so it could serve as the main vehicle for the deep-space exploration program. Therefore, the Sunkar proposal can be considered as the first step in building a more powerful family of space rockets in Russia.
Run as a single government entity, it appears to me that the Russian aerospace industry is struggling with its decision-making process. Without some internal profit-oriented competition, they have no method for focusing their efforts on any design. Rather than have multiple independent companies competing for profit with their own individual designs, Roscosmos’s management can only make its decisions after much office politics, the logic of which often has nothing to do with the best or most efficient concept. Their one saving grace is that, rather than competing with themselves to thus encourage fast and efficient development, they will be competing with other countries — especially the American private sector — and that will eventually give them the impetus to build something.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

Mr. Zimmerman: You are correct, there is quite a chaos in the Russian launcher strategy and designs. It is a pity, because the RD-170/180/190 engine family should allow a wide-range of competitive launcher (even displaying reusability), which could cover up all the payload range from Cosmos (about 1 ton) to Energia launcher (about 100 metric tons). It seems that the modular concept behind Angara has failed, because its basic module is too small to fit to heavy launcher designs. I hope Russian launcher designer will be able to find an intelligent solution for this design problem of a launcher family, which can be funded. However, seen under the light of stage reuse, all concepts look like old fashioned and a bit obsolete. This is also a pity, because Russian engineers showed in former times very advanced ideas in this field.
