USN seeks authority to use Galileo L12 (GSAT0225 &
GSAT0227) spacecrafts for support of tracking and commissioning operations of launch of the
Galileo L13 scheduled for launch in September 2024, and not commercial service to the United
States, and thus believes that Section 25.137 does not apply.

Galileo L13 launch is planned for Sept. 13th 2024 from Cape Canaveral/Florida.

Given the previous Galileo launch expended the booster (B1060), I have a strong feeling another booster will be expended for this launch too.

Seeing as this launch is only 2 million euros cheaper, it seems like a safe bet.

How much has it moved?

Still targeting September.
To this date, the Galileo constellation has 30 First Generation satellites in orbit and an additional eight are ready to be launched, two in September this year and six more starting in 2025. Second Generation launches will begin before the end of this decade.

early September, and there maybe some interesting changes.
-
If I were to guess, a launch vehicle change.

I think its more likely they will try to land the booster on the dronship!

That was my initial guess when I saw the phrase "interesting changes".
But if my guess is right, then the Galileo sats may be placed into an elliptical orbit, them having to circularize that orbit afterwards. That's performance penalty from the fuel reserves after MECO.
i dont think galileo has apogee kick motors and so has to be placed directly into MEO
if it can launch them w booster reusable odds are it cant be put in a very eliptical orbit

I was using logic based on the GPS-III launches when the first launch expended the booster and inserted the satellite into an elliptical orbit with the perigee at 1,200 kilometers. When SpaceX began recovering the booster starting with GPS-III 3, the perigee was 800 kilometers lower (400 kilometers).
GPS-3 has an apogee propulsion system, Galileo does not have one, so this is not an option here.

If I remember correctly, a Galileo FOC satellite have 8(?) MOOG 1N thrusters and about 70 kg of fuel.
That is plenty for maneuvers and a very long satellite life, but not enough to circularize a transfer orbit.

This will now move a bit due to the stand-down
-
Given the successive LC-39A launch campaigns Starlink 10-9 => Starlink 10-6 => Crew-9 => Polaris Dawn (if there is time) => Europa Clipper:
I think this launch will be from SLC-40.

My bold:
Ben Cooper's Launch Photography Viewing Guide (https://www.launchphotography.com/Launch_Viewing_Guide.html); updated August 9 (after Starlink 8-3 scrub):
The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on August 10 at 8:50-10:48 a.m. EDT. A Falcon 9 will launch a Starlink batch from pad 39A on August 10 earliest at 7:27-11:27 a.m. EDT. A A Falcon 9 will launch the Worldview Legion 3 & 4 satellites from pad 40 on August 14 at 9:00 a.m. to 12:00 p.m. EDT. The first stage will land back at the Cape about eight minutes after launch. Upcoming launches include more Starlink batches. A Falcon 9 will launch the Polaris Dawn spaceflight participant mission from pad 39A on August 26 in the early morning EDT. Upcoming launches include more Starlink batches. A Falcon 9 will launch the BlueBird-1 mobile communication satellite for AST Mobile on early September. A Falcon 9 will launch the Galileo L13 navigation satellite mission for Europe on September TBD.
