These two NGA Space Debris notices (the same notice for two different Navigational Areas) look like they are probably for this launch.

Map from the NGA Space Debris notices. Like SDA T0-F1, the orientation is consistent with an 82° prograde orbital inclination.

SDA-0B launch heading is about 169 deg, giving an estimated inclination 81-82 deg prograde. Same launch time as the previous FAA announcement.

Fairing recovery is only 340 km down track, about half of a "normal" launch pattern. I think that suggests a more vertical high altitude jump on the first stage, what I call a "firework" profile. That in turn suggests an easy option to take a large dogleg, offering a range of inclination. That's what SpaceX did for the later Starlink Group 6 launches.

Did you mean 340 miles? That would align with Raul who says 526 km:

No, I got 343 km from the FAA ZLA data. I made a small mistake in averaging, so that should have been 349 km, but still just 217 miles.
But clearly he has additional data, another bulbous part extending south of the little rectangle I have. That's the difference. I agree with his estimate, with his extra data source.

Go Crusader departed PoLB on Aug 29 @ 8:55pm PT (11:55pm ET), potentially for fairing recovery operations

[UPDATE:  corrected PT & ET]

At almost the same time, Port Canaveral was shutting:

EFFECTIVE 9:00 PM 8/29/23 PORT CANAVERAL AT CONDITION "ZULU" The U.S. Coast Guard Captain of the Port (COTP) has set hurricane condition "ZULU" for Port Canaveral. Sustained gale force winds are predicted within 12 hours. Port Canaveral is closed and has ceased all waterside and vessel shoreside Port operations until further notice. 
 
Based on current forecasts and storm information, Port Canaveral is not issuing a marina evacuation order for Hurricane Idalia. Vessels berthed at marinas located in Port Canaveral should consult with their marina owner/operator and comply with marina specific requirements and precautions.

Targeting Thursday, August 31 for Falcon 9’s launch of @SemperCitiusSDA's second Tranche 0 mission to low-Earth orbit from SLC-4E in California → spacex.com/launches

SpaceX is targeting Thursday, August 31 at 7:26 a.m. PT (14:26 UTC) for a Falcon 9 launch of the Space Development Agency’s second Tranche 0 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. If needed, a backup opportunity is available on Friday, September 1 at 7:26 a.m. PT (14:26 UTC).

The Falcon 9 first stage booster supporting this mission previously launched Sentinel-6 Michael Freilich, DART, Transporter-7, Iridium OneWeb, and eight Starlink missions. Following stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base.

The space vehicles launched during this mission will serve a part of SDA’s Proliferated Warfighter Space Architecture, a new layered network of satellites in low-Earth orbit and supporting elements that will provide global military communication and missile warning, indication, and tracking capabilities.

A live webcast of this mission will begin about 15 minutes prior to liftoff.

Nine hours later SpaceX will conduct another launch, with the Starlink Group 6-13 lifting off from SLC-40 at the Cape.

To which class does the one York Transport satellite onboard belong, A or B? I remember there should be one of each class left to be launched among the York ones.

Based on SpaceX website's launch page, looks like they've delayed about half an hour.  Coverage site set to go live about 7:45PT/10:45ET.

Thirty minute launch delay; how long is the launch window?  (Probably confidential or classified)
