It's definitely a (the) theme.

[Vahe231991]

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

[Targeteer]

United Launch Services LLC, Centennial, Colorado, has been awarded a $10,666,286 firm-fixed-price modification (P00024) to previously awarded FA8811-19-C-0002 contract for Delta IV heavy launch services. The contract modification is for Space Launch Complex (SLC)-37 non-routine facility expenses. Work will be performed at Cape Canaveral Space Force Station, Florida, and is expected to be completed by Oct. 1, 2022. Fiscal 2021 missile procurement funds in the amount of $10,666,286 will be obligated at the time of award, and the total cumulative face value of the contract is $1,304,953,956. Space Systems Command, Los Angeles Air Force Base, California, is the contracting activity.

SFN Launch Schedule update, March 25 (one of many):
NROL-91 confirms launch in August 2022 from Vandenberg SLC-6--last Vandenberg Delta IV-Heavy.

[zubenelgenubi]

Any new news?  August is approaching fast.

[Newton_V]

Any new news?  August is approaching fast.

Still on track for a summer launch.

[xcel102]

Still on track for a summer launch.

Still true after the Minotaur II+ explosion?

[Vahe231991]

Still on track for a summer launch.

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.

[zubenelgenubi]

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]

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.

The Firefly Alpha isn't exclusively intended for sun-synchronous polar orbits, it's also designed to carry satellites into near-equatorial orbits on a westward path. The next Firefly Alpha launch won't be intended to reach polar orbit, but the third Alpha launch (now planned for November) will.

Erm come again? Westward equatorial orbits? Where did you see that? The performance hit for that would be astronomical.

I meant to say orbital launches with a westward trajectory, not equatorial orbit, since Vandenberg SFB is north of the equator. But that doesn't change the fact that the next Firefly Alpha launch will launch on a westward trajectory.

Jesse.  Just admit you are posting incorrect information (again).  Because Firefly Alpha is designed for sun synchronous orbits, it can fly over SLC-6.   THAT IS THE POINT

[gongora]

For its next launch Firefly is going to 137 degrees and shouldn't go anywhere near SLC-6.  I expect that trajectory won't be commonly used after the initial test launch, but the conversation in this thread was about whether the upcoming Firefly and DIVH launches would conflict.

I've checked and it's in the DB as such since almost a year ago. I think it's meant to be "NET Q3 2022".

August is part of Q3. As someone has noted on this thread, NRO at times keeps planned launch dates for upcoming launches confidential until the rocket for NRO missions reaches the launch pad.

Attention now moves to the west coast and the Delta IV Heavy rocket, which ULA is readying for a September launch with the NROL-91 mission. This mission for the National Reconnaissance Office will likely see the deployment of a heavy optical imaging satellite.

The ULA website has NROL-91 as the next ULA launch.  To me, that indicates it precedes the SES-20 and SES-21 launch.

The Delta Cryogenic Second Stage is a cryogenic liquid hydrogen/liquid oxygen-fueled vehicle, powered by a single RL10C-2-1 engine that produces 24,750 lbs (110.1 kilo-Newtons) of thrust.

Is the RL10C-2-1 used for the first time?
Is this (simplified): a RL10B-2 with a engine controller of the RL10A-4-2, with variable fuel mixture ratio?
The final -1 means modernized?

As you mentioned, the C's are B's with the PU motors from A's.
There are also A, B, and C cones, not to be confused with the RL10A, B, C.
I would say it's more like the RL10C-1 with the NEDS and bigger cone.

The graphic says 98deg sun-sync orbit, but that's almost certainly wrong. It conflicts with the NOTAMs from 2 agencies, and with the video released by ULA.

When the NROL-91 is launched for good, the US Space Force could potentially issue badges to ULA officials and employees featuring a lightning bolt and a hammer, given that the classic Delta SLVs were derived from the Thor ballistic missile (itself named for the Norse god of thunder).

No, they don't issue badges with logos.

United Launch Alliance Successfully Launches National Security Mission with Nation’s Proven Heavy Lift Vehicle
Delta IV Heavy continues to deliver high priority missions in support of National Security

Vandenberg Space Force Base, Calif., (Sept. 24, 2022) – A United Launch Alliance (ULA) Delta IV Heavy rocket carrying the NROL-91 mission for the National Reconnaissance Office (NRO) lifted off on Sept. 24 at 3:25 p.m. PDT from Space Launch Complex-6 at Vandenberg Space Force Base. To date ULA has launched 153 times with 100 percent mission success.

"The NRO has been, and continues to be, a phenomenal partner through 32 collaborative launch campaigns, stemming from ULA’s very first launch in 2006," said Gary Wentz, ULA vice president of Government and Commercial Programs. “This mission was ULA’s 96th National Security mission and the NRO’s 10th mission on board a Delta IV Heavy launch vehicle – a history that we are very proud of.”

“This was also ULA’s 95th Delta mission from Vandenberg Space Force Base and our fifth and final Delta IV Heavy from the West Coast, completing a long, successful tenure of delivering critical national security payloads,” added Wentz. “We look forward to preparing Space Launch Complex-3 for future Vulcan flights from the West Coast.”

ULA’s next launch is a commercial launch of the SES-20 and SES-21 mission, planned for Sept. 30 from Cape Canaveral Space Force Station, Florida.

Leveraging a legacy of 100 percent mission success launching more than 150 missions to explore, protect and enhance our world, ULA is the nation’s most experienced and reliable launch service provider with world-leading reliability, schedule confidence, and mission optimization. We deliver value unmatched by any launch services company in the industry, a tireless drive to improve, and commitment to the extraordinary.

And as a final orange flame flickers into the night at SLC-6… an 11 year reign of the most massive rocket to rattle the West Coast comes to a close, ending a lineage going back to Vandenberg’s first flight nearly 64 years and 2,000 launches ago.

Hard to express the emotions from this launch. Slick Six will be back someday, hopefully, but it probably won’t look the same. I’m glad to have been here as my first media launch, and my 17th in person. My first launch ever was NROL-45—an IV Medium. This feels fitting.

The Delta IV Heavy, like the now-retired single-stick Delta IV, shares little in common with all Delta SLV variants except the name Delta. The first Thor orbital launch with Delta upper stage occurred in 1960, while the first launch from Vandenberg of a Thor-derived rocket bearing the Delta name was in October 1966. Hence, the NROL-91 launch ends a nearly 54-year run of space launches from Vandenberg using orbital rockets bearing the name Delta (all Thor-Delta launches were conducted from Cape Canaveral).

The pitch "up" after separation of the two side boosters is interesting.  How does the vehicle appear to "roll" slightly as well with a only a single center mounted engine?

Same way the Delta II did: With a dedicated vernier engine. Using the Core Stage vernier engine, roll control is maintained after booster separation.

Yep.

Engine Specifics.
The new RS-68 is capable of operating in—and transitioning between—full power level and minimum power level upon command from the vehicle.  It also supplies pressurization gasses to vehicle fuel and oxidizer propellant tanks and thrust vector and roll control by gimbaling the thrust chamber assembly and the fuel turbine exhaust roll control nozzle.
