The American company conducted ground tests of a new rocket engine for a promising ICBM

The program to create a new American Sentinel intercontinental ballistic missile, which in the future should replace the already repeatedly upgraded Minuteman III ICBM, is entering a new stage. Northrop Grumman has successfully tested a new engine for the rocket's first stage.

Northrop Grumman reported on the successful ground testing of a new solid-propellant engine for a promising ICBM. As reported on the company's website, the engine worked for the allotted time, all indicators were normal. The next step will be flight tests of the new engine.

Passing the test proves the correctness of the approach of the Sentinel development team to the solution of the problem ahead of them and allows them to proceed with confidence to the next phase of testing. The engine worked for the specified time in accordance with the set parameters, all indicators were normal

- said in a statement.

The American Minuteman III ICBMs, designed specifically for confrontation with the Soviet Union, have been repeatedly upgraded, but their further use is unsafe. It was decided to create a new rocket. Boeing and Northrop Grumman participated in the tender for the development of a new ICBM, they also received design contracts in 2017. In 2019, Boeing left the project, while Northrop Grumman received the contract and defended the ICBM project in the fall of 2020.

Details of the development of the new ICBM are not disclosed, it is only known that under the terms of the contract, the new ICBM will have to use the Mk.12A and Mk.21 warheads from the Minuteman-III ICBM. Also, the new rocket should be universal, it may be placed on mobile platforms.

The US Air Force's GBSD (Ground-Based Strategic Deterrent) program assumes the gradual replacement of all 2027 Minuteman-III ground-based ICBMs from 450 and is estimated at almost $ 100 billion. Once adopted, the new ICBMs should remain in service with the United States until at least 2075.

They swallowed the live bait, not only do we make rockets instead of schools, but most importantly, because of their poverty, they make small rockets, now they are racking their brains how to stuff their version of our avant-garde.

alexey_444, why are you mirroring the Soviet rogue financial system on today's rich Russia? In our state, dozens of new schools are opened WEEKLY if you look at all regions, and these are schools from 500 to more than 1000 students, if you are interested - "Made by Us" tracks, with photos, videos, addresses, etc., come to check - no problem. And in general, the social spending of the budget is growing CONTINUOUSLY EVERY YEAR, even despite 14 thousand of the most severe sanctions in the history of mankind - the social spending of the budget of the Russian Federation GROWTH last year, all the indexations were carried out traditionally, and even ahead of schedule, the Russian State has no problems with money , despite the fact that social articles make up more than 60% of the federal budget items and the state defense order this year has been increased by almost 60% (!).
With regards to this A-35 Sentinel, the prototype of this nonsense (without the engine that they are trying to cut) was shamefully tested by the mptras at the end of spring 2022 (on the Minotaur-III +, not confused with the "second" and "third"), shattered into molecules and destroyed not only the launch pad of the site in California, but also the entire infrastructure within a radius of 400 meters, in short, an important object was scrapped.
There was no version of our Avangard, and there won’t be in the next 20 years, those feces that experienced “exceptional” at the end of the 2s and then tried to squeeze something out - comparing them with a 28 megaton ultra-precise 14MAX masterpiece of mankind is tantamount to comparing my former watch "Frank Muller" with Chinese ones of the same name (by the way, the Chinese Wu-5 nonsense at 100MAX and XNUMX kt to the "Vanguard" as to the Moon, but at least it functions for them).
And yes, taking into account the wild delay in the attempts with this "Sentinel", they will put it first even in 2030, by that time the "Minuteman-3" will have to be half written off or it will stick around in the mines for the sake of furniture, and now only on the 1st the stage is tested and periodically the launches are postponed so as not to disgrace themselves before the allies. Everything is like with that "Columbia" to replace the 30-44-year-old "Nuts" (by the way, one 2 days ago smoked near Z. Virginia, and the other on April 1, 2022, the ballast systems in compartments 1 and 2 exploded during repairs) capable of only two salvos - Columbia was first planned to be rolled out in the early 2020s, then moved to 2027, then to 2031, now we are talking about 2035. Well, according to tradition, it’s the same with plutonium pits, they haven’t been producing new ones since 1988, they intended to start under Oyama, then in 2018, then in 2024, now they’ve moved it to 2030, and so it is with Matrasostan in everything.

Avangard did not rest against them: we do not deploy new missile defense components. They are developing hypersonic missiles for non-strategic purposes.

[KCA]

We do not deploy at all, only Nudol and S-500 in the PGRK format

"repeatedly modernized, but their further use is unsafe"
Some nonsense. The use of special-purpose vehicles outside their shelf life is indeed: 1. unsafe; 2. meaningless. And why is the use of replaceable launch vehicles unsafe? If only they stand in the mines without replacement, with modernization on paper.

[Sarmat Sanych]

That's right, Gestas. Although two of the four upgrades were still not on paper, albeit a relatively long time ago.

[Disant]

so here it’s apparently not a matter of b / h - solid fuel elements dry out, they need to be changed.
well, at the same time, the rocket will be upgraded - some nozzle more suitable for the new fuel will be screwed on and brackets will be added for installation on the wheelbase.
loaded onto a boat, transported somewhere to Greenland or Alaska and cut the flight time in half.

[Ezekiel 25-17]

They will do it, but not on time and worse than the Russian one: their competence is in the past.
