SpaceX is almost certainly planning to launch these in big groups on Falcon 9 or Heavy. It could launch thousands of satellites using only a few dozen launches during a period of several years. If the company needed 100 Falcon 9 launches per year just to support this constellation, it would be a very bad business plan, IMO. (I'm skeptical of the plan even if they are launched en-mass, but we'll see.) - Ed KyleI thought the number was much higher than 100 kg.... More like 500 kg.... To the point where we weren't sure if a single F9 can do a full orbital plane's worth in one shot.Recent FCC testimony said the 4,425 sats summed to 1,700t IIRC. So, 384kg each. At 16-20 per F9, that's 220-280 launches. Three times that for the 12,000 sat constellation.At a 6 year mean lifetime (5-7 years in FCC application), that's 2000 per year indefinitely -- 100-125 F9 launches. This is why many see ITSy as the natural solution to Starlink deployment.

ITSy and a dispersal bus for Starlink.

But >10 years later, with the full benefit of hindsight, with enough time to gain perspective, and with a "how to do it right" example right there in front of you - to still not see it - that's just astounding..

Until used booster flights outnumber the new booster flights the F9/FH reuse cannot be considered an example of "how to do it right". We believe that SpaceX will be able to do this and do it with a reduction in the access to space but they have yet to acheive that milestone. They have on their schedule this milestone is NET than this time next year.There are two items that would enable the phrase:More boosters used than new.A general reduction in the $/kg or the general cost of access to space.They have yet to be demonstrated.

Reuse has yet to enter the picture and so far has yet to be income positive.

And "hope for your competitors to trip and fall on their face" is not a business plan. On the topic of this thread, if a company is not planning now for the disruption this will cause aren't likely to be long term competitors. (In the off chance that SpaceX implodes, the companies still benefit from trying to reduce their own costs.)Customers have already benefited from reuse. Contract renegotiation is the limiting factor for fraction of reuse flights at the moment. The next reuse is one that was originally stated clearly as would not be reuse. L2 has information about potential future reuse flights, which based on the rate at which reuse is taking hold in the manifest makes it seem unlikely that majority reuse will not happen. SpaceX has also been quite clear that they are currently making changes that will make reuse easier, cheaper and faster, and there is little reason to doubt that this will happen. Even if they only get it down to a week or even a month of work instead of their goal of a day, this will still be a significant cost reduction on top of the what they already have.

Jim is right. Musk said it cost like a billion dollars to develop reuse. I'm pretty sure it takes more than 2 launches to recover that.But I do consider it essentially proven at this point. Just a matter of time until it is the dominant method of launching. Doesn't have to be VTVL, could be VTHL or something, but fairly rapid reuse like that is inevitable at this point, IMHO. Blue Origin would've eventually done it if SpaceX didn't exist, so I wouldn't give SpaceX too much credit except for accelerating the timescale.
" and younger workforce with no paid overtime " <-- Sure Jim, it's all a facade.
