Given that this is this rocket's 23rd flight, was this really a "loss" for SpaceX or was the rocket already basically paid off.
I realize launches for Starlink make this a more complicated number.
SpaceX already dominated pricing with its cheap flights before reuse, built on cheap costs from vertical integration and advanced manufacturing processes (plus skilled workforce) but reuse made winning every launch contract even more lucrative and today no one else can possibly match them.
More importantly reuse lets them fly often as they refurb in about a month and have a fleet of about 16 boosters. That lets them hit 3 flights a week when the operation is going smoothly and that is how something like Starlink can be profitable despite requiring over 100 launches a year. The cadence is ridiculous and that could not be had without reuse at anywhere close to SpaceX's workforce sizing today.
Price estimates of a first stage are in the 15-20m dollar range so every reused stage will net them about that (minus refurbishing costs) as a bonus.
I could have sworn I remember there being an article about them doing something for the Government and they wanted a fresh rocket so it cost more. But maybe I am remembering wrong.
So roughly first rocket at cost and then if they are successful (which is for sure an incentive) the rest is profit above maintenance cost.
They've always made money on the bulk of their first flights but the income is much better for later flights where the booster is already paid for.
