We are seeing only what our brains can process and not the glorious actuality.

Re: Next Generation Rocket Angara: News
Perhaps a double weapon with a 1MT precursor charge that is released ahead of the main warhead... they both plummet down on Yellowstone national park... 1MT ground penetrating warhead blows open a big hole in the ground for the 200MT bomb to fall in to and explode to get things going...
Or they just might not tell us... which is also fine.

Re: Next Generation Rocket Angara: News
MOSCOW, March 6. /TASS/. The Angara-A3 medium rocket may be created, Roscosmos Director General Dmitry Rogozin wrote on Facebook on Saturday.
"As for Angara-A3, its production is possible, but not obvious, as Soyuz-5 with a payload of 17 tonnes is going to appear soon in this (medium) class," Rogozin said.
In April 2019, Rogozin said at a news conference that Roscosmos had never worked on the Angara-A3 medium-class carrier rocket. It had been previously reported about the Angara-A3 project in Russia. However, on April 1, 2019, Rogozin announced it would not be developed due to the Soyuz-5 launch vehicle project with similar payload capabilities.
The Angara is a family of next-generation Russian space rockets. It consists of light, medium and heavy carrier rockets with a lifting capacity of up to 37.5 tonnes. The new family of rockets uses environmentally-friendly propellant components. So far, Russia has carried out only two Angara launches, both of them from the Plesetsk spaceport: a light Angara-1.2PP blasted off in July 2014 and its heavy version lifted off in December 2014.

So far, Russia has carried out only two Angara launches, both of them from the Plesetsk spaceport: a light Angara-1.2PP blasted off in July 2014 and its heavy version lifted off in December 2014.
Wut? Maybe the journalist who wrote this was asleep during the 2nd A-5 test flight in Dec last year?
A-3 is superfluous for the time being as Souyuz-5 fills this lift category. Once Soyuz-5 is up and running from Baikonour and Angara is operating out of Vostochny then I expect Roscosmos will re-evaluate the cost/benefit behind A-3. It should be easy enough to adapt A-5 to A-3 config and fly from the Vostochny pad if the demand exists.
Interestingly, the Angara pad at Plesetsk doesn't seem to be a part of this process as the military doesn't (yet) have much demand for 17T-class launchers. Their payloads seem to be either relatively light birds in LEO or inclined Molniya-style orbits, or the odd heavy geostationary platform or multiple glonass (much less common these days as the constellation is essentially complete). Soyuz-2 currently satisfies most needs, and A-5 will take over from Proton when that wonderful hypergolic monster () is finally put out to pastures.
The Angara project has changed radically since 1992 when the idea was first floated of a new all-Russian rocket to guarantee the ability to launch national seurity payloads from Plesetsk. The Angara pad in the Northern Cosmodrome looks like an oddity until one remembers the background behind its genesis. Its fair to say that 3 launches in 7 years looks shit when taken at face value but its not an accurate reflection of the programs progress, and the low utilisation in these early years will be forgotten once the infrastructure development is done, the serial manufacturing is up & running, and the test programs are complete.

Re: Next Generation Rocket Angara: News
The successful launch in December gave hope that the intricate history of the Angara family of missiles has finally entered a predictable course. The next, third in a row, flight test of the heavy "Angara-A5" will take place in the coming months, and in total, six launches must be carried out before receiving the go-ahead for mass production. The main customers - the Roscosmos State Corporation and the Russian Ministry of Defense - believe in the new rocket. The fact is that, despite a number of interesting proposals for launch vehicles, the Angara will become a key carrier for the next decade in terms of supporting the most ambitious Russian space projects and regaining leadership in the launch services market.

Re: Next Generation Rocket Angara: News
and the Angara is a matter of "faith". This is how maggots infiltrate the information space and corrupt public opinion. Nothing
about the Angara program and the rocket itself merits such doomsday language.

30 years in development
It's not faith, it's blind fanaticism and crazy luck
Without 2014 this would still be just in scale model form
And it's still late

Re: Next Generation Rocket Angara: News
That is called bad management... the goal of the F-22 was to be the best of the best but the goal of the F-35 was an affordable high tech stealth fighter that could replace all existing fighters in all HATO air forces... so replacing all American and European fighters was the plan and the concept and the tremendously ridiculous plan made it certain it could never be affordable.
Production plants scattered all over the world to suit the wishes of the purse string holders... don't get the electronics from where they are made now... set up new factories in districts that vote for the senators or whatever that vote on funding for military programmes... they will never cut numbers if it means losing jobs in the places they get voted in... it is the opposite of centralisation and production efficiency... and it was rubber stamped on a jack of all trades plane that everyone was supposed to buy in enormous numbers because it worked on the C-17... they ignored the fact that it was not cut in numbers but they kept getting new planes without having to ask for any to keep production running... which is great for any programme... but for a programme that doesn't need to be cheap but should be affordable, the prices they were paying for C-17 should have told them this was never going to work... but they ignored that because while the train is moving they earn lots of money... and nobody seems to be held accountable... who knows where the money went... nobody is even checking.
But obviously it is Russian management and Russian corruption that is the problem in this case...
And you don't understand why we look at the situation they are in and think there are no serious problems here...

Re: Next Generation Rocket Angara: News
The Proton-PM company (part of NPO Energomash integrated structure of Roscosmos) has started to master production of the RD-191M engine, a modified version of the RD-191 for Angara launch vehicles. The first unit is to be manufactured in the beginning of 2023, the same year NPO Energomash will start testing it.
The RD191M is a modification of the RD-191 engine boosted by 10%. The engine will perform the assigned tasks during launches of heavy versions of Angara rockets from the Vostochny Cosmodrome, including crewed program. To do so, the developers have introduced a number of changes to the product.
‘When creating the RD-191M, the design and technological groundwork for the RD-191, RD-171M, RD-180 and RD-181 engines is used to the maximum, significantly reducing development costs,’ says Pyotr Lyovochkin, NPO Energomash Chief Designer. ‘In 2021, we will fully release the engine design documentation and hand it over to the manufacturer.’
Under the agreement signed in December 2020, Proton-PM will manufacture three RD-191M engine prototypes. The first one is intended for development tests, the second for final development tests, and the third for interagency tests.
‘For the first time since the beginning of the development of the RD-191 engine at Proton-PM, a contract was signed not for individual components, but for the product as a whole, which greatly facilitates the development process,’ the engine project manager Igor Timshin adds. ‘It is also important to take into account that the units and assemblies assigned to the enterprise make up about 40% of the RD-191 production labor intensity, and the RD-191M engine has a high degree of continuity with the prototype.’
To master the production of RD-191M, over 1,200 new technical processes and 3,500 tooling designs will be necessary to release. In addition, in 2020–2022, six existing testbeds will be modernized, five more to be designed and manufactured. The RD-191M engine assembly site is to be organized in the first quarter of 2022. It will be located at a suburban production site in the new building 82.

MOSCOW, August 25 - RIA Novosti. The third launch of the Angara-A5 heavy-class launch vehicle from the Plesetsk cosmodrome is planned for the first half of December, two sources in the rocket and space industry told RIA Novosti.
"The launch of Angara-A5 with a new Perseus upper stage and a mock-up of a spacecraft from Plesetsk is scheduled for the first half of December," the agency's source said.
Earlier it was reported that the Khrunichev Center, under a contract with the RF Ministry of Defense, is to produce six Angara-A5 missiles for flight tests. Two of them have already departed in 2014 and 2020 with the Briz-M upper stages and spacecraft mock-ups.
In addition, the enterprise, by order of the military department, is to produce four serial Angara-A5 missiles. In December 2020, the general director of the Khrunichev Center, Aleksey Varochko, said that they would be delivered to the customer in 2022-2024.
Angara is a family of environmentally friendly launch vehicles of various classes. It includes light carriers "Angara-1.2", heavy ones - "Angara-A5" and modernized "Angara-A5M", increased carrying capacity - "Angara-A5V".

PARK PATRIOT (Moscow region), 25 Aug - RIA Novosti. The first oxygen-hydrogen upper stage of KBTK, which will significantly increase the carrying capacity of the Angara launch vehicle , is planned to be launched in 2027, Sergey Kuznetsov, general designer of the Salyut design bureau (part of the Khrunichev Center), told RIA Novosti.
"At present, Roskosmos has begun to actively fund the KVTK theme. The work has been fully launched. We have defended the draft design and are now at the stage of issuing design documentation and manufacturing stand products," he said at the Army-2021 International Military-Technical Forum.
“We hope to complete this work on time and launch the first aircraft in 2027, most likely on the Angara-A5M launch vehicle,” Kuznetsov added.
In December 2020, Roscosmos signed a contract with the Khrunichev Center in the amount of 20.6 billion rubles for the creation of an oxygen-hydrogen upper stage at KBTK. In the course of the work, which is planned to be completed by December 2025, it is planned to make models and prototypes, as well as conduct their tests.

Re: Next Generation Rocket Angara: News
Russian Defense Minister Sergei Shoigu arrived on a working trip to the Plesetsk cosmodrome, Zvezda correspondent Pavel Remnev reports. He is accompanied by Russian Deputy Defense Ministers Timur Ivanov and Alexei Krivoruchko.
The head of the Russian military department will check the progress of modernization of the assembly and test building of the cosmodrome, where the heavy Angara-A5 launch vehicle is being assembled and tested.
Shoigu also heard a report by the Commander-in-Chief of the Russian Aerospace Forces Sergey Surovikin on the planned launches of Angara-class missiles until 2027. Surovikin also reported on the schedule of flight tests of the Angara-A5 and the progress of the tests of the Perseus upper stage complex.
As reported to the Minister of Defense Surovikin, the new assembly and test complex at the Plesetsk cosmodrome will be commissioned by the end of this year.

Re: Next Generation Rocket Angara: News
This is natural, because Perseus is a modification that uses kerolox. Thus, you need large tanks for the oxidizer, unlike the "Breeze-M", which uses a fuel pair of NDMG + AT

Perseus will add significant capability to Angara, so this 3rd flight is an important mission.

Re: Next Generation Rocket Angara: News
You're confusing modifications. You named the total mass of the Briz-KM upper stage, which is used for Rokot rockets. The main modification, "Breeze-M", takes on board up to 20 tons of NDMG + AT. In addition, the Perseus unit can take up to 18.7 tons of kerolox. The difference in the total mass of the components is due to the fact that kerolox has a slightly higher specific impulse compared to NDMG+AT. The difference in size is due to the fact that NDMG+AT has a higher density than kerolox, therefore, requires a smaller volume of tanks.Big_Gazza wrote:Blok-DM-03 is a modernised variant of the original Blok-D that was developed for the cancelled N-1 manned lunar rocket. Its bigger than Briz mainly because it is a much higher capacity stage (17.3 T vs 6.5 T for Briz).

Yes, you're correct! I missed that, so thanks for the correction!!
Went back to the books to check and find that another reason why the Briz-M stage is shorter than Blok-D is that the Briz-M core stage (based on KM) sits inside a jettison-able toroidal outer tank and is a very compact design with good volume utilisation. Blok D on the other hand has an ellipsoidal LOX tank sitting above a toroidal kerosene tank and is much less efficiently stacked. Briz M contains more propellant's by volume, yet is only 2.6m in length, compared to 6.3m for Blok-D.
Blok-D is an older and less efficient design, but it has been flight proven over many launches, is very reliable, and it uses non-hypergolic propellants. I guess those factors outweigh the increased stack length, as long as the mission profile doesn't require multiple firings.

Russia to launch new Angara light carrier rocket in first half of 2022
The Angara is a family of next-generation Russian space rockets
MOSCOW, December 3. /TASS/. The launch of a new Angara light carrier rocket is scheduled for the first half of 2022, Roscosmos Chief Dmitry Rogozin said at the EAEU business forum ‘Space Integration’ on Friday.
"The launch of the light Angara will take place in the first half of next year," Rogozin said. The launch of a heavy Angara carrier is targeted for the end of December this year, he added.
Commander-in-Chief of Russia’s Aerospace Force Sergey Surovikin earlier reported to Defense Minister Army General Sergey Shoigu that work was currently underway to assemble an Angara-A5 rocket whose launch date would be determined on December 20.
The Angara is a family of next-generation Russian space rockets. It consists of light, medium and heavy carrier rockets with a lifting capacity of up to 37.5 tonnes. The new family of rockets uses environmentally-friendly propellant components. The first two launches of Angara heavy rockets took place from the Plesetsk spaceport on December 23, 2014, and on December 14, 2020.
