Interesting that the original licenses for Starlinks 6-22, 6-23, and 6-27 were from Vandy but these new ones are now saying they will launch from the Cape

Could this be USSF-124?

A presentation from the US Space Force has USSF-124 on Falcon 9 for September 29th 2023, and USSF-52 on Falcon Heavy for September 1st 2023.

Not sure perhaps that in 2024 is meant to be by 2024?

Do we know if USSF-36 & NROL-69 will be droneship or RTLS or expended?

Maybe it's a Fiscal Year thing?

And no, we do not know whether USSF-36 & NROL-69 are ASDS, RTLS or Expended.

What does "flyover" mean?

What does "flyover" mean?

Flyover of the VSFB South base instead of going out over the Pacific and dogleging over to avoid flying over the base, especially when another launch vehicle is being prepared (i.e. Delta V heavy at SLC-6). Since being given future lease access to this launch site, SpaceX has been using the flyover option almost consistently, saving on fuel on the dogleg maneuver. The location of the landing barge is different on each option, necessitating a separate FCC license.

Jim may have clearer info as he has worked here on many occasions.

Also, this does not cover the dogleg that is done at Stage Separation (illustrated in the second photo)

The last two photos are examples of the Dogleg Option. Note the flight deviation right after launch to avoid the base flyover (red allow). The fourth photo shows that the landing barge has to be positioned in a different location to accommodate the change. The FCC license has the coordinates for the landing barge annotated.

If I understand this, both flyover and dogleg are coast-hugging launches, and they both involve a bend in trajectory? But it happens at different time points in the launch.

Edit for clarity.

As stated, yes.

Details and background:
The final orbit inclination for the mission is a crucial factor. Trajectories with final orbit inclinations farther away from the west coast may still require a flyover dogleg until the payload inclination is far enough west that the immediate dogleg is no longer necessary. The immediate dogleg is put in place to prevent launch failures that could potentially damage other launch facilities, launch vehicles, or public beaches during the first minute of launch. Launches from SLC-6 typically don't have this restriction, but Atlas and SpaceX locations do. Delta II Launch Pad, due to its more western location by the airport, is not as restrictive.

In the past, launches from VSFB were mostly for westward missile testing, retrograde launches, and polar orbits that didn't require the initial flyover dogleg. However, SpaceX has taken on the challenge of flying inclinations that are more eastward, passing over land and hugging the west coast while avoiding Mexico during power flights.

The second dogleg is only required to place the vehicle into the correct orbit inclination, which may come at a Second Engine startup or even later in the flight to GEO flight. A second dogleg is also necessary to avoid overflight from Mexico (Baja California, Cabo) during the powered flight until the vehicle reaches orbit, similar to the process of preventing overflight over the Bahamas. The SpaceX landing barge cannot be too close to the shore or the islands that dot the west coast. Thus, the initial leg of the flight until MECO may take one trajectory, targeted for the landing barge, then SES begins the second dogleg to get the payload to the mission payload inclination.

Rockets with strap-on boosters also had to wait to dispose of them until they passed over oil derricks that also dot the west coast.

Lastly, an FCC license is required to request and grant permission to transmit and receive communication from the LV ton and from receiving assets (including the barge) for specific frequencies.

It's worth noting that the same flyover doglegs are necessary when SpaceX launches in a southern inclination from LC-40 and 39 to avoid overflight of Cape assets (Air Force base, other LCs) and populated areas along the eastern coast of Florida (Fort Lauderdale, Miami, etc.). (See Attached SATCOM-1 photo)

Overall, these flyover and dogleg maneuvers are present on both coasts and are dependent on mission profile, public safety, and U.S. military asset requirements when flying close to land or "Coast Hugging."

Hope this overly clarifies this. Now back to the thread. (If I missed something it's because I forgot my coffee)

Could be the difference between MVac engine versions, whether they use the short nozzle or not. If they do, possibly save money. But it could impact cadence out of pad 40 with use of a droneship.
