Even 20 annually for more than a few years (as SpaceX clears its delayed backlog) is optimistic.In all history only two launch vehicle families have managed to fly more than 20 times per year for any length of time: R-7 (1960s-1990s) and Thor (1960s). R-7 peaked at roughly 55 per year during the 1980s, but the payloads that drove that cadence (Cold War film return recon) are gone. During this decade, all of the rockets in all of the world's countries combined have only managed an average of a bit less than 83 orbital attempts per year. - Ed Kyle

If the demand (money) is there, the launches will proceed apace.

Motorola and Teledesic together were looking at launch rates that were comparable in the 1997 time frame. Been there, bid those, business never materialized.

Their payroll alone is likely over half a billion per year! They also need profit to roll into development of the Mars system.I'm talking about the cost of the actual rocket and launch, not the price SpaceX will need to charge to stay solvent. The 10% I'm guessing at there are things like range fees and payload integration. This was a discussion about the limits of cost reduction on Falcon 9, which I'm saying land around 80% without S2 and 90% with it. With a high enough launch rate, SpaceX's internal cost for a launch should approach that. Realistically, I don't expect to see Falcon 9 launches sold for less than maybe 40 million for the foreseeable futureMy "spot on" was mostly directed at the fact fairing and possible S2 reuse were sort of getting tossed out of the discussion.

Using the Inflation Calculator the cumulative rate of inflation was actually 13.7%, so SpaceX pricing has actually FALLEN over that 9 year period, not risen.That's what the fact show.The facts also show that SpaceX is nowhere near reducing launch costs by an order of magnitude (ignoring the several orders of magnitude reduction required for Mars for the moment). It's all fugazi.True. And they will continue to not dramatically lower their prices.As of now they already undercut *everyone* on price, except Soyuz (iirc 3 tons to GTO) and small launchers. With their current prices, they can't service all their potential customers yet, need to up the launch rate some x2.Why on Earth would Musk voluntarily cut his revenue today by lowering prices even more?

Not so long ago when I suggested SpaceX would not lower prices much below their competitors, people were getting rather upset and I was told SpaceX is not like any other company. How times have changed.

I think it was in the late 60s or early 70s when it approached 150, but to predict 200 launches by SpaceX in a year is just FANtasy

If anyone can take the next step, it is them.Getting to space was pure fantasy 30 years before the R-7 'run.' Repeating their feat 30 years later seems less fantastic -- in fact, is seems odd that it isn't routinely done.The stagnation that smothered the launch industry for decades is what is fantastic (-ly sad).Oh, wasn't Shuttle supposed to fly weekly (50x per year)? Possibly the failure to reach that program goal -- and its tarnishing the concept of reusability -- caused the launch trough.

Only if "assured access" is part of the "compete" equation--assuming SpaceX does not FU. That is, one provider is subsidized either explicitly or implicitly to ensure assured access; e.g., guaranteed X launches or via ELC.The definition of "assured access" in the law is simpler -- Quote(1) the availability of at least two space launch vehicles (or families of space launch vehicles) capable of delivering into space any payload designated by the Secretary of Defense or the Director of National Intelligence as a national security payload; and(2) a robust space launch infrastructure and industrial base.Nothing about financial arrangements, other than that whatever they are, they must keep two providers in business. So if, say, Blue and SpaceX are both certified, and getting by without subsidies or guarantees, there's no reason to provide either. (See https://www.law.cornell.edu/uscode/text/10/2273. And note also that ULA is no longer getting ELC, though it still has some guaranteed business over the next few years through the somewhat controversial block buy.)ULA is still getting ELC. For Phase 1A competitions, though, they have to bid without it. Same with Phase 2 competitions.The USAF catch phrase for keeping one particular provider in business is 'Managed Competition' -- better known as allocation -- wouldn't be needed (and it is needed) if free and open competition would produce the same result.

When Will Boeing and Lockheed Martin Lose This $1 Billion Government Subsidy?
The Air Force will award ULA one final ELC contract this year -- probably in September, as has been its past practice. But this will be the last such $1 billion subsidy ULA receives. Going forward, instead of dividing its spending between one contract for EELV and a second contract for launching rockets "under the requirements contract terms" of EELV, the Air Force will pay just one consolidated price per space launch -- one single "P-1 line" item.
200 per year is certainly fantasy without significant re-use. I think SpaceX and Blue Origin are the only organisations on a path that could enable such a high launch frequency within, say, 10 years. Of course there has to be the demand too. Mega-constellations may provide that but too early to say if they will be successful.

It is not at all clear that most or even many of the proposed constellations will fly, and I can almost guarantee that if they do, they will be significantly scaled back in number of spacecraft.
