Does anyone has info, how many WorldView-Legion satellites are on one Falcon-9 launch?

The plan is now for two satellites per launch.

Two on the first launch, four on the second launch, because two are going to polar orbit and four to mid-inclination

Maxar plans to launch the second two WorldView Legion satellites approximately three to six months after the first launch, Jablonsky said.

It appears that things have changed, unless Spacenews made a mistake. But it’s been a few days and it would’ve been corrected by now.

It seems Space News made a mistake.

On quarterly earning call they said still looking at around the end of September for the first flight (two sats to polar orbit), and talking to SpaceX about potential launch windows for the second flight (4 sats to inclined orbit), probably very early 2022.

expecting Q4 launch (from earnings call).  Still have several items driving schedule risk, including finalizing software, a problem with some supplier components that's affecting several manufacturers, and some mitigation for a production issue found in testing of the optical instrument.

Maxar CEO Dan Jablonsky, Q1 2021 earnings call (1700 EDT, 03 May 2021)
Quote
At this point, we're tracking a few critical items that could impact time lines to launch.

The first of these is completion and validation of flight software, which is complex and continued simulation and testing of this spacecraft and its components and subsystems. Next, there's an industry-wide issue with some aspects of Honeywell electronic components that have been identified and need to be corrected. We're using these Honeywell electronic components on the first of our Legion satellites.

As I noted, the entire satellite industry is being impacted. Notably, Maxar's Legion program, though, has been designated as a high priority defense mission and has formally received a DX rating under the Defense Production Act. We're basically front of the line alongside other DX-rated programs that are close to it and preferential treatment and resolving this issue. And at this point, we're optimistic that this is not a pacing item.

Finally, we put our satellites and systems through a rigorous set of environmental testing to validate the engineering, the design, the quality and construction and work that goes into the build. We and our suppliers do that as additional validation measures. During April, one of our suppliers, Raytheon, had been conducting those same sorts of tests on the high-precision optical instruments. They unexpectedly encountered an issue during testing not related to design but due to some workmanship in an assembly of a supporting component.

Maxar requested some adjustments to the orbital parameters (this flight is Block 1 SSO).

Maxar made an FCC filing that updates the orbit for the first two SSO sats to 518km, 97.47deg.  I really wouldn't be surprised if they end up sitting on top of the Transporter 3 stack.

Delayed until the March-June timeframe (which happens to be the timeframe of two other Transporter launches, so I'm still guessing that might be what they'll use).  Program is running a couple months behind schedule (delayed hardware deliveries with second optical instrument not expected until September now, testing, software, etc).

Maxar Q3 2021 Financial Report

Quote
“Importantly, we also signed a contract with a fifth U.S. ally to upgrade the country’s ground infrastructure to be Legion ready and we were awarded contracts to build two new GEO satellites for Sirius XM. Finally, we advanced the Legion construction program and continue to expect the launch of the first two satellites in the March to June 2022 window.”

Maxar still confident Legion constellation will be in orbit in 2022

https://twitter.com/jeff_foust/status/1471047457576562691

Quote
Maxar’s John Cartwright says at a #WSBW panel this morning they’re expecting to launch the first set of WorldView Legion satellites in the second quarter of 2022, with the second set 3-6 months later.

I asked if the six Legion satellites would be launched in batches of three, or two on one launch and four on the other; Cartwright declined to say. The company has previously said two on the first and four on the second.

Huh, I really thought these would end up on a Transporter launch.


[Press Release] Maxar Reserves May 15 - June 13 Window for First WorldView Legion Launch
Maxar Technologies (NYSE:MAXR) (TSX:MAXR), provider of comprehensive space solutions and secure, precise, geospatial intelligence, today announces it has reserved a window of May 15, 2022 - June 13, 2022 with SpaceX to launch the first two WorldView Legion satellites.
...
“We continue to execute against our plan to complete the WorldView Legion program to the highest possible standard of quality,” said Chris Johnson, Maxar SVP of Space. “Testing of the first satellites is underway and given the criticality of this mission and a potentially crowded SpaceX manifest this spring, it was important to secure this launch window. I am proud of the team’s progress this year as we make WorldView Legion’s game-changing capabilities a reality for our government and commercial customers in 2022.”

Latest amendment for the constellation shows the planes still as:
2 satellites in SSO, ~510km altitude
4 satellites at 57deg inclination, ~540km altitude
4 satellites at 45deg inclination, ~520km altitude
2 satellites in SSO, ~590km altitude

The company said the first pair of WorldView Legion satellites is now likely to launch on a SpaceX rocket in June or July, and the remaining four satellites, under construction now, are now slated to launch in two missions three and six months later.

This is seems to confirm there is a Legion-3 mission planned for December 2022 or later. Originally, we thought there would be only two launches.

[Space News] Maxar eager to launch new satellites amid soaring demand for imagery over Ukraine
Quote
Most recently, the launch of the first two satellites that had been projected for early summer could be pushed to the right again because of a shortage of Ukrainian Antonov cargo aircraft used to transport spacecraft from factory to launch site.

The first two satellites will be transported by truck from Maxar’s manufacturing plant in Northern California to SpaceX’s launch facility in Cape Canaveral, Florida. That could add a couple of extra weeks to the schedule, said Jablonsky.

Maxar initially had booked two SpaceX launches for the Legion constellation: one for the first two satellites and the second for the other four. But it later decided to add a third, splitting the constellation in pairs to be launched in three-month intervals, said Jablonsky.

The launches are now scheduled for September, December 2022 and March 2023.

Maxar Technologies has delayed the launch of its first two WorldView Legion optical imaging satellites by 2-3 months, to September, following a wrongly designed satellite test sequence that will add about $20 million to the program’s cost.

Maxar has scheduled three SpaceX Falcon 9 launches for the six Legion satellites. Under the scheduled that Maxar updated on May 9, the launches would now occur in September, December and March.
