Northrop Grumman is moving production of the engines and structures for its Antares rockets to the U.S. from Russia and Ukraine, a move that will have cascading effects throughout the space industry.
The aerospace giant said Monday it will move Antares production fully to the U.S. through a partnership with Texas-based Firefly Aerospace. Northrop Grumman had purchased Russian RD-181 engines to power the Antares 230+ series, and the rocket’s main body was manufactured by Ukraine’s Yuzhmash State Enterprise.

OK.

It’s called “home sourcing”.
They must have just gotten word there was problems with producers in the Ukraine and Russia.
The talent for succeeding at this endeavor has long since retired.
It's long past time to look for a different solution.
It’s a bitch trying to recreate gramma’s secret sauce from scratch especially when you want to leave out the hooch and other volatiles or environmentally unfriendly compounds that give it that special kick
Why the sam hill was an American company building rockets in the two of the world’s most corrupt nations in the first place?
U.S. efforts to duplicate or replace these Russian engines has been going on since the 90’s and has been abandoned multiple times along the way ... a different solution.

SpaceX’s Raptor 2 motors burning liquid methane and liquid oxygen ... methalox. Replaces the kerolox fuel of the Russians. 11 million HP each.
When the Feds allow SpaceX to restart the Starship project, it will eventually produce launches for $1 million each with reusable boosters and Starships relaunched at a rate of 4 a day. 100 T to orbit initially then stepping up to 200 T to orbit with each launch.
I can only assume you've never been in the business?
Perhaps you've added up the costs for: Range Time? (was $1M/day in the 80s) Fuel? Expendable material? Wages?

Costs are per launch, per E. Musk. Take it up with him, please.
can’t put a price on independence, Larry
relying on the Russians was idiotic from the beginning
the US developed the F-1 rocket engine for the Saturn V, the most powerful engine in the World, so they’ll have no trouble developing new engines

Sadly you’re exactly right. But look at the BRIGHT SIDE, we have FAR BETTER tort lawyers, groomers, and childhood experts.
...and they’re running the country now.
It’s crap, no matter who said it.
I spent a career in the business and worked closely with the team trying to replicate Russia's (USSR's) RD-180s. They spent over 10 years and hundreds of millions of taxpayer dollars and never got close.
As for you assertion as to what the U.S. developed (F-1s) you might want to look at the history. (Operation Paperclip)
We brought an entire team (1600) of Germany's rocket scientists back to the U.S. after WWII, including Wernher von Braun.
So please list the innovative, successful multi-billion dollar companies you have personally started and any other expertise you might have acquired by reading wiki pages.
Then you can take that vast business acumen and advise Elon Musk on how successful business are run. You can give him realistic goals like how to reuse rocket boosters, how to make electric cars and other way out there products. yo can tell him his current goals are unrealistic, and he should bail now before Blue Horizons runs him into the ground.
Or you could just go back and finish high school.
It is not possible to launch objects on the order of 10,000 lbs. to orbit for $1M.
My career in Aerospace spanned 45 years and I have a Master's Degree.
Support from multiple tracking ranges is required during testing before and during launch. in the 1980's when a launch had to be slipped to the next day, the standard metric was that range support cost was $1M/day.
The fuel costs alone exceed $1M.
The launch crews don't work for free.
Only a fraction of the rocket is re-used and the cost of recycling the rocket is not free.
You can waive around the Musk quote, but you can't prove those per launch costs are achievable.
Just give it up and stop shooting the reporter. You can go listen for your self plenty of EM material on YT. Plus, you demonstrate you have absolutely NO familiarity with the StarShip project.
Its not up to me to prove anything, other than you are obviously trolling.
Free Lunch coming soon!
Now you have proved yourself a troll of the lowest sort.
It is not "trolling" to itemize the costs that illustrate that $1M/per launch is not achievable.
If Musk is launching 52 satellites at a time, there may come a day when his launch rate is high enough to spread his costs out, and be able to charge $1M PER SATELLITE placed in orbit.
$52 Million per launch would be extraordinary, but achievable.
