Rocket Labs is aiming for the small/medium satellite market where customers
don't want to pay for a dedicated flight of a F9, and don't want to wait for a
transporter rideshare program (either because of schedule or to get a specific
orbit). Right now with Electron, they can launch 500-700Kg to orbit vs the F9
13,000 rtls, 18,000 drone ship, 23,000 expended (falcon heavy can get to 68,000
expendable)
Their next rocket (Neutron) will be a reusable 1st stage and super-cheap 2nd
stage with an early design goal of 13,000 drone ship landing payload. It could
be real competition to the F9 (even limited to smaller payloads)
Rocket Labs is one of the few companies that I expect to survive (as they are
working on a partially reusable rocket), but they will
be a 2nd or 3rd tier provider.
with the exception of RFA (see below), I don't see any expendable rockets
surviving very long
ULA talks about possibly modifying a Vulcan to break the engines off the first
stage and landing them, then building a new 1st stage for the next flight (and
2nd stage). Their target is to eventually hit 24 launches/year.
RFA is working on expendable designs, but using super cheap parts (automotive
grade parts, not aerospace parts), which sounds dangerous at first, but if you
think about it, cheap automotive grade parts are better quality (more
consistant dimensions and materials) than manually milled space parts were back
in the '60s.
Stoke is working on a fully reusable rocket. It's a very interesting design, but
their current design is for 5,000kg payload capacity (if this design works, they
may scape up)
Blue Origin is saying they may fly New Glen as early as October. It's 1st stage
is designed to land, and per a recent interview, Jeff Bezos has two teams
working on the 2nd stage, one with the focus of building a reusable 2nd stage so
efficient it makes no sense to use an expendable one, and the other team working
on an expendable 2nd stage so cheap it doesn't make sense to use an expendable
one. If New Glen works, it will be in the same class as a Falcon Heavy with a
design payload of 45,000kg
SpaceX Starship is designed to be fully reusable and have a payload capacity of
100,000-200,000kg with launch costs in the same ballpark as Neutron
A few years ago Elon Musk said that fuel for a Starship would run around
$1m/launch and launch pad, manpower, permits, etc run another $1m. Neutron
needs less fuel, but the expendable 2nd stage costs, and (more importantly)
limits the flight rate to the 2nd stage production rate. A lower flight rate
would be fewer flights to spread the fixed costs (manpower, faciliites) across.
So it's a toss-up which would end up cheaper.

True that. I started to work only in the early 2000s and it was in
automotive. Imagine my shock, when I transitioned into general aviation and
I found out that tolerances etc were less strict than in automotive. It's
really counterintuitive, but it's like that.
All the best,
