Do you just throw away the landed Block 3 and 4 cores - who can each be reflown 2 or 3 times with refurbishment? Or do you use them until they have expended their economic use - despite having Block 5's available that can fly 10 times, with minimal refurbishment.Just use the Block 3 and 4s for expended mode launches until the lot is run out.Doesn't that undercut Falcon Heavy, though? I presume they don't want to undercut FH once it's flying.

Well, FH isn't flying yet, so there's still a need for expendable missions. Additionally, FH can't fly out of SLC-40 so that means you have a bottleneck at 39A which is also the only place to launch the upcoming Commercial Crew missions. I could see some customers wanting to not stand in manifest line the very busy 39A pad and opting for expendable instead.
I don't think SpaceX cares about undercutting Falcon heavy. FH is probably going to be a pain, with higher chance of failure. Except for government launches, I bet it'll be phased out in favor of something in the ITS family within a few years.

What are you talking about?
Hofeller said many SpaceX customers — “I won’t say a majority, but it may be a majority” — have expressed interest in converting their contracts to previously flown stages.

There's Gwynne's comment of 3-4 more customers this year looking to re-use, plus all the positive quotes in this thread. I was looking again the other day at some 2015?/2016? press around Ariane 6, saw quote saying no market demand for re-use ...Two of those customers, SES and Iridium, are talking multiple flight-proven vehicle rides within the next 6-9 months. USG, both NASA and USAF, probably are not in the mentioned 3-4, but both are in the not-if-but-when camp. Jury still out on whether all FH flights (except maybe STP-2?) will be reused only. Still looking like we could enter 2018 with a manifest going forward that is 50% reused boosters or close to it.The 'no market demand for reuse' was repeated this week at Paris Air Show...I think 2018 is going to *have* to be at least 30% reused. We know they're only producing 20 rockets/year right now, and LC 40 alone will be able to use them all. I doubt that they're going to increase that rate, so even if there are only half a dozen launches each at 39A and 4E the launch rate is going to require a pretty high reuse rate. Even more so in 2019 with Boca Chica online, and I suspect at that point they're going to want to shift some of the Merlin production line to Raptor.Once Block 5 starts to fly (and performs up to design), there will no longer be demand or need for 20 new cores per year. They may have hit peak production of Falcon in 2017.

Considering the fact that the % of used booster that would fly this year to the total number of boosters to fly will be about 25%, the ability to fly a higher percentage (>50%) of used boosters in 2018 is not only likely but is also likely to change many customers' minds over the use of used boosters. A savings of just $10M when using a used booster that has equal or better reliability than a new booster as well as a possible decrease in insurance costs may very well change the tentative use of used boosters by commercial customers into a flood.

Once used boosters are flying regularly, people's gut feel about them will change quickly -- particularly if those used boosters are giving those people's competitors an advantage, in terms of schedule, price, or both.

They may have hit peak production of Falcon in 2017.If Block5 can get 10 re-uses, they only need a production capacity of around 8/year to get 80 launches/year for first stages, but 2nd stage production will have to grow from 20/y to 80/y.Merlin Production will have to go from around 180 M1 and 20 M1Vs (200 total) to 72 M1s and 80 M1Vs (152 total)seems pretty doable.A launch cadence of 80/year (when Constellation is going up) is going to crater fixed costs per launch, on top of the S1 re-use savings. SpaceX is going to have enormous pricing power that no one is going to be able to match. I wouldn't be surprised under such a scenario if the cost to SpaceX to launch a Falcon 9 is only around $20m.
You know with pricing like that Oneweb might rue their decision to sign such a huge launch contract with Arianespace for those Soyuz launches because the reality is they will have likely overpaid to get there fleet into orbit. I get the competitive side of them vs SpaceX probably being a factor but the savings they likely gave up could have funded a huge amount of future constellation hardware etc.

Going with SpaceX is bad for them because they're dependent on their competitor. Going with another launch provider is bad because their launch costs are a lot higher than SpaceX's.It's hard to know which of the two is worse.

OneWeb went with their only option to get a jump on ConnX.
They should receive a significant discount on Soyuz launches give volume.
Plus Ariane have excellent record of launching on time as long as locals play nice.
