Viasat Shareholder Letter: Q3 Fiscal Year 2024 Financial Results
February 6th, 2024
[...]

During the quarter our antenna supplier completed its root cause investigation of the ViaSat-3 F1 antenna deployment anomaly. Based on its findings and recommendations, we are implementing several corrective actions on the ViaSat-3 F2 antenna. We expect to complete those actions as well as extensive testing and spacecraft integration by early calendar 2025 with launch expected shortly thereafter. The scheduled launch of ViaSat-3 F3 remains on track for late in the fourth quarter of calendar 2024. The F3 satellite has a different antenna design by a different supplier, and its schedule is not affected by the ViaSat-3 F1 anomaly.

[...]

The antenna supplier concluded its ViaSat-3 F1 reflector anomaly investigation with root causes identified and corrective actions developed for application to the ViaSat-3 F2 satellite. We expect the reflectors with supplier corrective actions implemented will be delivered to Boeing in late calendar 2024 with anticipated spacecraft launch in the first half of calendar 2025.

I wonder if they will swap this with the F3 satellite (originally planned as ViaSat-3 APAC) instead, since the later remains planned for launch in Q4 2024 - now before F2 is ready - and is currently without a ride after Arianespace’s Ariane 6 contract was dismissed. I expected the new launch contract to be announced here (very likely SpaceX) but that didn’t happen.

ViaSat-3.3; the assumption is that Falcon Heavy is/will be the launch vehicle.

Blue Origin’s New Glenn rocket is not expected to be available for a commercial mission in time for when Viasat says the third ViaSat 3 satellite is scheduled for launch in late 2024.

That leaves SpaceX’s Falcon Heavy and ULA’s Vulcan rocket as the most likely contenders for the contract to launch the ViaSat 3 satellite for the Asia-Pacific region.

The second ViaSat-3 satellite was slated to launch on an Atlas 5 rocket from United Launch Alliance this fall to cover Europe, the Middle East, and Africa (EMEA). The third and final ViaSat-3 satellite targeting Asia Pacific (APAC) is due to launch half a year later.

ViaSat-3 EMEA uses the same antenna as ViaSat-3 Americas, and Dankberg said changes to its launch schedule also depend on the corrective actions it takes.

“It was pretty close to being able to launch when we had this antenna anomaly, he added.

ViaSat-3 APAC uses a different antenna so its launch is unaffected.

Quote
Satellite operator Viasat has encountered unexpected business challenges as a result of problems with the deployment of its ViaSat-3 Americas satellite. During the launch earlier this year, an issue with the giant reflector for the antenna occurred, which could impact the satellite’s performance. Analysts estimate that the total costs, including construction and launch expenses, amounted to $700 million. The satellite was intended to play a crucial role in providing faster broadband coverage across a wider area.
...
Flight 2, which was scheduled for launch in September, has been postponed, and a rescheduled launch date will be announced next quarter. Viasat is currently investigating the root cause of the reflector anomaly with the antenna manufacturer and satellite supplier. Dankberg mentioned that Flight 3, which has a different design from a different manufacturer, is expected to be unaffected by the Flight 1 anomaly.

https://www.theregister.com/2023/08/10/viasat_reports_revenue_up_but/
Quote
Flight 1 refers to the ViaSat-3 Americas satellite, launched to provide coverage in the Americas, which should mean that Flight 2 is the ViaSat-3 EMEA unit and Flight 3 would be the remaining ViaSat-3 unit intended to cover the Asia-Pacific region.

The Flight 2 satellite was understood to be scheduled for launch in September, but this has now been postponed, and the company said it will have more information on a rescheduled launch next quarter.

Dankberg revealed that Flight 2 uses the same antenna "from a major aerospace supplier" as the first satellite, but that "Flight 3 uses a completely different design from a different manufacturer," and that satellite is expected to be unaffected by the Flight 1 anomaly.
...
Viasat is currently working with the antenna manufacturer and its satellite supplier to determine the root cause of the reflector anomaly and appropriate corrective actions for Flight 2, Dankberg said. The company expects to have more to report on the fault in the next three months.
...
When asked whether Viasat might procure a "Flight 4" satellite to cover the region intended to be served by Flight 1, Dankberg said it does have plans which cover that eventuality, but added "what we'll do for a replacement satellite depends a lot on what the performance of this one is."

Edit/add; apparently:
ViaSat-3.3 (APAC) will launch on Falcon Heavy in (CY) late Q4 2024.  However, the launch vehicle/launch contract has not yet been confirmed.

That lack of confirmation is also why there is not yet a forum launch thread for 3.3.

ViaSat-3.2 (EMEA) will launch on Atlas V 551 in (CY) H1 2025.

OK, I'm confused. There are two satellites here: ViaSat-3 F2 and ViaSat-3 F3. There were originally three. F1 launched and then failed to fully deploy its antenna.  The satellites were originally supposed to launch on Arianne 6, Atlas V, and Falcon Heavy, in that order, but ViaSat cancelled the Arianne 6 contract and launched F1 on a Falcon Heavy. So, which of F2  or F3 is now supposed to launch on Atlas V, what LV will be used for the other one?  The shareholder letter says F3 will launch in calendar Q4 2024, and F2 will launch in calendar 2025.

There are contract option for additional SpaceX flights of which an MoU to keep the options was exercised following the first launch. There is also a ViaSat-3.4 which was relegated to ground spare status when it's previous project partner backed out of the joint venture for the series.

The Viasat 3F3 has now overtaken Viasat 3F2.
The dates given are the start of service. A launch date cannot be determined from this.
After the launch with an Atlas V 551, Viasat 3F2 will need a few months to reach GEO.

Tory confirmed there are no more Atlas V launching this year, so ViaSat-3 F3 is not launching on Atlas V in Q4.

ViaSat-3 F2's launch is planned for the 1st half of 2025 as mentioned earlier in the thread.

Are there any more Atlas launches planned for this year? Or will it only be USSF-106 and USSF-87?

We currently do not have a launch thread for the third ViaSat-3 satellite launch.

Seeking confirmation or correction:

ViaSat-3 F3 is currently scheduled to launch in H1 2025 and will serve APAC (east Asia and the Pacific).

ViaSat-3 F2 will launch later in 2025 and serve EMEA (Europe, Middle East, and west Asia). No launcher has been confirmed.  We have mentions on the forum of launch by Falcon Heavy and Ariane 64.

Will Viasat launch F4 (the ground spare/test article)?

Cross-post:
They're still not saying launch vehicles or launch dates.  Notes from today's earnings telecon:
In-service dates: F2 late 2025, F3 mid-late 2025
F2 over Americas, F3 over Asia-Pacific
F2 has longer orbit raising time than F3

This quote could be interpreted as launching on a reusable Falcon 9.

Quote
The VS-3 F3 manufacturing and test schedule outlook is unchanged from last quarter, but given our significantly increased coverage and capacity resources, we have chosen a less capital intensive launch configuration that has slightly extended the orbit raising time, which is expected to shift the commercial in-service date for VS-3 F3 into CY2026.

ViaSat-3 F2 was awarded to ULA (see multiple posts upthread), and as far as I know, there have been no statements made by Viasat that would confirm or imply that they have switched.
