I've made my points, and so I'm not going to rehash the same point-by-point arguments. However, I will generally challenge others to:- Think about New Armstrong in the context of the actual addressable market, not the total market. What fraction of 85% of payload mass to orbit is payload mass that New Armstrong could actually tap into? What fraction of the addressable market today are single launches to single orbits versus mass-constrained constellation deployments?- Pay attention to the difference between constellation operator profits and launch profits. Starlink generates a lot of profit for SpaceX, because SpaceX and Starlink are one and the same. If SpaceX IPOed Starlink tomorrow, what would the resulting SpaceX profit profile - i.e. launch profits only - look like?- Think about ROI in terms of margin. A constellation may generate a lot of revenue, but as a tightly-negotiated and tightly-competed block buy, the margins are thin. A launch company would be well-served to consider what the actual profit margins are on any particular mission.
Quote from: RedLineTrain on 09/06/2024 02:41 pm@sstli2, I have reread your posts and I agree with much of what you say. But low margin businesses are Amazon's and therefore Bezos's stock-in-trade. They can be great businesses and indeed low margins can create a competitive impediment against those who are unwilling to dabble in such activities.New Armstrong's business case is dependent on Kuiper, maybe more than it should be. I am a bit lukewarm on Kuiper. I observe that Amazon has many demands on its capital investment dollars and that this could pinch Kuiper. Kuiper in any ambitious form is a multi-ten billion dollar endeavor. Competing against Starlink with its current ambitions might require $10 billion per year in capital investments. I wonder whether Amazon is capable of sustaining that rate for something that while strategically good, is not existential to the business and that results in an inherently high-cost product.Bezos could choose to expand the markets for which New Armstrong is suitable. He is an O'Neill disciple, so he may wish to create space stations. That would provide a good second market for New Armstrong.Lastly, we should keep in mind that Musk has oscillated between Starship and reusable upper stage for Falcon 9. It is not so easy to decide which is a better use of time and money. Bezos will encounter this dilemma.If Starship is cheaper than New Armstrong (and all others) then Amazon will likely see a another shareholder lawsuit if Bezos tries to force Amazon to avoid Starship. This already happened with Falcon 9.IMO Kuiper will not be successful. It was a long shot when it was supposed to launch in late 2022, and it is losing potential customers to Starlink for every month of delay since then. It does have Amazon itself as a large captive customer (including every Amazon delivery truck) but I doubt it's enough. By the time New Armstrong launches, Kuiper will no longer need it, one way or another, so New Armstrong would need a different mega-constellation, and by then, the market will be saturated by Starlink and possibly a Kuiper struggling to survive, so another successful constellation is unlikely.

Falcon 9 and Starship are wonderful resources that Amazon should not be shy to utilize, if the timing of its preferred launch providers does not line up perfectly. It has surprised me to watch Bezos, a world-class businessman, fail to grasp this fully. It's a measure of how strongly Amazon is committed to Kuiper.
Today Starship is the only fully reusable launcher that is in development

It has surprised me to watch Bezos, a world-class businessman, fail to grasp this fully. It's a measure of how strongly Amazon is committed to Kuiper.Kuiper added three F9 launches in December 2023 to fill in for delayed introductions by their primary LVs. Those three appeared to allow them to make their FCC deadline of 1618 satellites by July 2026, at least on paper in an alternate universe where all the LVs achieved the launch schedules projected at that time, and the Satellites were ready. None of that seems to have happened, so they will miss the date. I'm not sure how that affects New Armstrong, but it's at least possible that Kuiper will not be a relevant customer when New Armstrong is introduced.
I know that the only acknowledgement of New Armstrong is one comment by Bezo from years ago. However, I'm going to speculate a bit.Seeing NG's first booster it made me think that New Armstrong could just be an upsized NG. Widen the diameter to 10 meters or so and add another ring of 10 or 12 BE-4's for a total of 15-17 booster engines. With downrange booster recovery and hydrogen upper stage(s) a NA vehicle could be very formidable.Then the rest of the vehicle is just upsized, using the same basic design materials, chines, strakes, flight and recovery systems.NG has been a very long wait but NA could be an evolution with many things proven out on NG.

Probably 10 meter-ish core and a 12 meter ish bottom skirt. A stronger smaller BE-4 would help naturally but how many years would that take Blue to develop?

Comparing the base size of New Glenn and SuperHeavy isn't really fair. Raptor has the highest chamber pressure of any rocket engine, ever. BE-4 flew for the first time a few months ago. It's like comparing Michael Phelps to someone on the high school swim team.Give Blue a couple years to fly their engine and learn it's ins and outs. The base of New Glenn won't get any bigger or smaller, but I'm pretty confident it's thrust (and therefore thrust density) will go way up.

I know it'll improve, but it's at a huge deficit, and Raptor's not done either.
A 19 circle (5 across) would be about 9/3*5=15 m across.

Quote from: meekGee on 10/31/2024 09:43 pmA 19 circle (5 across) would be about 9/3*5=15 m across.I believe that should be 7*5/3 = 11.7 m for a 19 engine version as New Glenn is 7 m wide, not 9 m.
But the skirt (engine circle) is about 9. I'm calculating what the skirt of a 19 BE-4 hypothetical rocket would look like.
