I think the term "core" in this context means the center booster. I agree that until customers start using high-energy returned boosters in a single stick launch, Falcon Heavy might be the only avenue to reuse some of the flight proven block 3s and 4s. It seems economically unlikely that all three boosters in the Demo 2 mission will be block 5s.

Spaceflight Now has updated their launch schedule, putting STP-2 NET June 2018.
I'm just a space fan, please correct me if I'm wrong!

Spaceflight Now has updated their launch schedule, putting STP-2 NET June 2018.
Isnít the most likely reason the much later launch of FH-Demo? 6 months to:
- review all launch data
- review all FH Demo hardware (safely landed in one piece)
- adjust design where needed
- build brand new improved block 5 center core
- build OR convert 2 side cores

All given a successful flight of FH Demo...

I'm wondering whether they'll reuse the center core and perhaps the two side cores.

If not I'd guess they'd convert two B4 cores for boosters, and 1 B5 for center. Just a guess.

The vehicle for this flight should be all new Block 5 cores.

Ah, nice!

We have a date! NET April 30, with two month window stretching to June.


STP-2 is scheduled for a window from April until June and Arabsat is confirmed to be second launching Falcon Heavy, according to NASA's budget released today (Page 537).

As I think I've mentioned before, I've got tickets to this launch courtesy of the Lightsail Kickstarter years and years ago, so I've started clearing my schedule!

Well, that was the schedule when FH Demo was going to fly in December...  If this is still the third FH then unlikely it flies in that window.  If it swaps places with Arabsat 6A then it would still be possible (but probably not April, I'm guessing F9 Block 5 doesn't even debut until mid-April.)

Does the STP-2 contract stipulate new cores? If not, it might be possible to launch 6A and assuming full recovery be ready to launch again in ~6 weeks, if Elon's gas and go model pans out.
Launches attended: Worldview-4 (Atlas V 401), Iridium NEXT Flight 1 (Falcon 9 FT)

The contract we've seen is almost 6 years old and has been amended multiple times since then.  We really don't know for sure what's in it now.  I would assume new cores.

Elon indicated that the single stick block 5 debut flight would be in a couple of months.

In this context, I think STP-2's launch date is going to be highly contingent on the launch of Arabsat 6A, which will in essence be the debut of an entirely new iteration of Falcon Heavy derived from Block 5. If SpaceX is also required to build an entirely new Block 5 Falcon Heavy for STP-2 on top of the new vehicle for Koreasat, late 2018 may be a more realistic launch window.

The U.S. Air Force is targeting that month for its Space Test Program 2 mission, or STP-2, a spokeswoman for the Space and Missile Systems Center said in an email.

Given that FH side cores are interchangeable with F9 cores, FH launch contracts that stipulate new cores will be handled building the 3 new cores, launching the set, then giving the side boosters interstages and launching them as F9 cores.
And if Arabsat accepts reused cores, it could launch with two previously flown F9 cores as side boosters.
It seems SpaceX will end up with 3 or 4 FH center cores, enough to launch to a long while.
