That seems a bit premature. BO don't even have a Moon rocket, but they are "offering the Moon"? PR stunt if i ever seen one :P

Yeah, nobody else would do something like promise a Mars landing based on a rocket that exists only on powerpoint slides.

The opposite would also be funny. “We're building this huge rocket, but we won’t tell you what’s it for until it’s done!”

Actually, that might be more scary than funny.

It's the nature of aerospace that you have to start with the mission before you can even start on the design, so people are always promising new planes and rockets and such before they have started building them.

Arguably SLS, seeing as they change it's ultimate goal every few months.

Bezos certainly has money to develop a Moon rocket though. So if there are contries/companies/space organisations/whatever interested in going there and they can pay for the ticket he will build it.

Someone needs to pay for New Armstrong and it is certainly useful if you already have a paying customer.

BO is making a cryogenic upper stage for NG, which is gonna happen—it’s more real then Vulcan at this point, for example.

Small scale lunar landers are entirely within the payload capabilities of NG.

Well, there is some precedent. I recall that they were at least talking with NASA about a BE-3 powered cargo lander for lunar missions.

The BE-3 seems like it would be kind of overpowered for a lunar lander. With a lunar TWR of 2 you could have a 165t spacecraft. Whether that's the mass you're deorbiting or trying to lift off the surface, it's still huge.

Local TWR is greater than 2 for most reference designs, simply because lunar gravity is so low, but yeah.

How much propellant would be needed? How much would the tankage for that weigh? How about landing gear?

If you account for all of that, the available payload mass winds up in the same ballpark as the throw mass of New Glenn, especially if you start reusing upper stages as tugs to carry cargo to Lunar orbit.

Are you saying that they're going to use the NG upper stage as a lander?

No, I'm not saying that. I'm saying, if it were up to me, I'd find a way to turn NG's upper stage into a reusable tug, then use that to pick up payloads delivered by another NG and take them to the Moon, where a dedicated BE-3 powered lander then takes the payload to the surface. It would leverage a lot of existing tech and experience that's already been proven, and could be a decent opportunity to partner with ULA to give them an opportunity to use the work they've already done towards ACES and orbital propellant depots.

For normal missions NG looks like have enough performance to recover upper stage, assuming 40 ton to leo is with first stage reuse, else it would be low performance  with the huge rocket. 
But yes for stuff like manned moon you discard upper stage, but this is a bit like the dual falcon heavy moon mission idea, New Amstrong is the real tool for this,  from the scale it would be BFR sized, note that you would still have an fully reusable launcher for standard satellites.

I highly doubt they plan for New Armstrong to be a seperate bigger launch vehicle anymore. With the talk about refueling tugs and New Glenn already being 7 meters in diameter, there doesn‘t seem to be a need for it anymore.

I'd say put it on the back burner until there eventually is a need for it.

From my perspective, NA is still more of a concept than an actual plan. They still need to get NG to the pad first, let alone flying. Heck, as far as I'm aware, they haven't even gotten BE-4 to full power yet, let alone running a full mission duration burn. New Armstrong is a long ways off, if it's even happening.
