Upcoming launch of the SDA Tranche 1 Transport Layer A mission on #SpaceX’s #Falcon9 vehicle

Interesting questions. I don’t think we’ve yet seen any hardware that would suggest they have started building dedicated tanker ships yet. S42 (Flight 15) is definitely the pez dispenser variant (door slot is visible), and S43 must be as well, as Flight 16 has been referred to as “Starlink 30-1” in some documents.
They should be able to perform propellant transfer tests with the current ships simply by loading fewer (or no) Starlink satellites, leaving more residual propellant.
I think the limiting factors for starting propellant transfer tests will be how quickly they can launch two ships back-to-back, and how long a ship can remain in orbit. I recall that they mentioned that the batteries on ships limit their operational life time to a few hours, and that this was one of the factors which led to their decision to bring S41 back after two orbits rather than six. They need to either extend this (solar panels seem the obvious solution) to exceed the turnaround time of Pad 2 at Starbase Texas, or wait until LC-39A in Florida comes online, which seems like it could be imminent.
Which do you think is more likely for propellant transfer tests? Back-to-back launches from the same pad, or one launch from each?

Were all the cameras trained on the Falcon triple-header today?


Side booster landings confirmed!


Nominal side booster entry burns.


Fairing separation confirmed.


Boostback burn shutdowns, MECO, stage separation, and M-vac startup confirmed.


BECO, side booster separation, M-vac chill in, and boostback burn startup confirmed.


Max-Q.


Liftoff!


Propellant loading is complete on all three cores and the upper stage.

Weather is looking good.
This upper stage has the stripe grey insulation on the RP-1 tank, which is characteristic for long-duration missions. Perhaps this is satellite is going direct to GEO?


Hatch is open.


Hard capture complete.
Launch abort at T-58 seconds.
That will be a scrub for today.
