Yep.  "circa" is a good word to use.

Anybody know who this is?

Question: why is a picture of a WW2 general featured in a thread about NROL-91?

It's definitely a (the) theme.

Did the NRO decide to set the launch date for the NROL-91 at the beginning of next August because they felt that scheduling the launch for the middle of 2022 could free up the NRO budget for NRO launches involving the Falcon and Minotaur?

August would be near the end of the fiscal year

Still true after the Minotaur II+ explosion?

The launch of the NROL-91 atop the Delta IV Heavy is unaffected by the failed Minotaur II+ launch because the latter was carried out at the TP-01 facility, which was a launch site for the LGM-118 Peacekeeper, whereas the NROL-91 launch will be the last Delta IV launch from Vandenberg SFB.

NROL-91 launch scheduled in late August?  I presume the Delta IV Heavy has been stacked for some time?

Would the Alpha launch overfly SLC-6?
Edit/answer: Upcoming 2nd launch--no.  Future launches, most of them to SSO--yes.

Or do the Alpha WDR and/or Static Fire pose a potential threat to NROL-91?

Or is it the reverse?  The DIVH WDR poses a potential threat to Alpha and SLC-2W?

And, what are the other launches?

Firefly gears up for second Alpha launch [dated Jul. 17]

Quote from: SpaceNews
Firefly Aerospace is preparing for the second launch of its Alpha rocket in late August or early September, hoping that a successful mission can enable a “step change” in activity for the company.
<snip>
Schumacher said [Firefly] will have to work around a few government launches scheduled, such as a Delta 4 Heavy launch of a National Reconnaissance Office payload. “If they don’t move, we’ll probably be looking at a launch in the first or second week of September,” he said. “If those government launches are delayed for any reason, we might be able to sneak into the last week of August.”

The SLC-2W launch site for the Firefly Alpha is far north of the SLC-6 launch site, and the Firefly Alpha is designed to carry out flight trajectories to the west, unlike the Delta IV Heavy being used to launch payloads into polar orbit. Therefore, the Firefly Alpha can't overfly SLC-6.

No, Firefly Alpha is designed for sun synchronous orbits, which are polar and hence SLC-6 is affected by the flight path, just as it was for Delta II launches from SLC-2.
