When will the ViaSat-3 satellites launch?

For the first ViaSat-3 satellite over The Americas, service launch to support commercial services is anticipated in the first quarter of 2023 (Viasat’s Q4 for fiscal year 2023). The second ViaSat-3 payload (EMEA) shipped to Boeing July 8, 2022. Its service launch is anticipated for 2023. The launch date of the third satellite over APAC is TBD.

According to a Twitter post from last March, launch of the ViaSat-3 is scheduled for March 2023:
https://twitter.com/pbdes/status/1503745190208712720

The ViaSat-3 will be the last commercial geostationary satellite launched by an Atlas V following today's launch of SES-20 & SES-21, and after it is launched, the Kuiper Systems satellites will be the only remaining commercial satellites to be launched from the Atlas V.

Not true. We don't know what USSF 51 is.

I wanted to clarify that the ViaSat-3 is the last remaining commercial geostationary satellite scheduled for launch aboard an Atlas V, but you're right, most orbital parameters for USSF-51 remain classified for the moment.

Cross-posts; I'm sure that this will delay the Viasat-3.2 launch:

VIASAT 3 [56370, 2023-060A] was launched from the cape by a @SpaceX Falcon Heavy for @ViasatInc on May 1st.  Today, I was updating my Ku beacon library and came across the TT&C signal of what I believe is this object.  However, something seems off.🧵⬇️

Quote
From the previous tweet's video you can see the telemetry signal for the object being tracked fade very deeply in a periodic manner.  This is very unusual for a geostationary satellite that should have 3-axis stabilization to aim it's giant antenna and smaller TT&C antennas. ⬇️

https://twitter.com/coastal8049/status/1677884385536913408

Quote
An astute reader would wonder why I heard the TT&C beacon on Ku-band and not the operational Ka-Band the spacecraft intends (is) using.  They have their TT&C on Ku according to FCC filings.  See page 5-6. ⬇️ https://fcc.report/IBFS/SAT-MOD-20190617-00047/1737836.pdf

Quote
The plot below shows the odd signal level behaviour from suspected VIASAT 3 over this afternoon when compared to a 'normal' GEO satellite beacon from SES 2 beside it.  Notice the suspect VIASAT 3 fades in and out while SES 2 is stable for the ~10 minute period of this plot.⬇️

https://twitter.com/coastal8049/status/1677884390825922560

Quote
Here's a plot of the suspected VIASAT 3 signal over four hours showing wild yet usually periodic variations in the central carrier's signal level.  The period appears to slowly change over time.  It could suggest commissioning activity or an issue with the spacecraft. 👀 🛰️🛑

That's not good.

.@ViasatInc's Viasat-3 Americas satellite launched May 1 suffers major antenna-deployment anomaly. After more than a month of effort, it's still not fixed. Possible $420M insurance claim and a serious blow to Viasat's near-term growth plans.

Viasat Provides Status Update on ViaSat-3 Americas Satellite
12 Jul, 2023, 16:37 ET

CARLSBAD, Calif., July 12, 2023 /PRNewswire/ -- Viasat, Inc. (NASDAQ: VSAT), a global leader in satellite communications, today disclosed that an unexpected event occurred during reflector deployment that may materially impact the performance of the ViaSat-3 Americas satellite. Viasat and its reflector provider are conducting a rigorous review of the development and deployment of the affected reflector to determine its impact and potential remedial measures.

"We're disappointed by the recent developments," said Mark Dankberg, Chairman and CEO, Viasat. "We're working closely with the reflector's manufacturer to try to resolve the issue. We sincerely appreciate their focused efforts and commitment."

Contingency plans are currently being refined to minimize the economic effect to the company. Potential options include redeploying satellites from Viasat's extensive fleet to optimize global coverage, and/or reallocating a subsequent ViaSat-3 class satellite to provide additional Americas bandwidth. The initial service priority for ViaSat-3 Americas has been to facilitate growth in the company's North American fixed broadband business.

There is no disruption to customers from this event, and no impact to coverage or capacity of the respective Viasat and Inmarsat constellations currently in service. Following the Inmarsat acquisition, Viasat has 12 Ka-band satellites in space, excluding ViaSat-3, with eight additional Ka-band satellites under construction.

The company will share additional information on the status of the ViaSat-3 Americas satellite and any necessary contingency plans during its earnings call which is planned for August 9, 2023.

.@ITU gives @ViasatInc until July 29, 2023, to start service on Viasat-3 EMEA satellite at 13.8E using Israel-registered spectrum. Late-March 2023 launch on @ulalaunch Atlas 5.
...

It's still effective I believe. How will the ITU react?

ITU usually grants extensions as long as the request is reasonable - but at some point, if there are too many delays it could be trouble.

That was extended last year. Shorter than Viasat wanted at the time. It may be extended again, we'll see.
https://advanced-television.com/2022/04/25/itu-warns-viasat-that-time-is-tight-for-emea-launch/

The satellite is already too late. In addition, there will probably be a delay due to the first satellite's antenna problem. And if Viasat-3 EMEA takes over the duties of Viasat 3 America, another delay.
This is going to be a long letter to the ITU.

According to the Next SpaceFlight website, the ViaSat-3.2 EMEA is now scheduled to launch NET January 2024.

= TBD 2024

Viasat: We understand what caused the Viasat 3 Americas antenna defect
September 18, 2023

 Viasat Inc. said it has a “pretty good understanding” of why the 18-meter-diameter mesh antenna reflector on its Viasat-3 Americas satellite did not correctly deploy, and that its manufacturer expects to correct the problem on an identical antenna on the Viasat 3 EMEA satellite to launch in the coming months.

Viasat Chief Executive Mark D. Dankberg said the EMEA satellite is still scheduled to launch before the third and last Viasat-3, covering the Asia-Pacific, which does not carry the same antenna.

More(?) confirmation re: launch delay into 2024 from last ULA/SLC-41 launch of 2023:
Following the launch of the Project Kuiper Protoflight:

Quote
United Launch Alliance Successfully Launches First Mission in Partnership with Amazon
October 6, 2023

[...]

ULA’s next launch is the inaugural Vulcan mission from Cape Canaveral Space Force Station in Florida. The next generation Vulcan rocket will offer unprecedented flexibility in a single system with streamlined operations and greater affordability, while continuing to provide unmatched reliability and orbital precision.

Yes delayed indefinitely as 3.1 is in the process of getting written off and the 3.4 spare will have to be launched to replace 3.1 via insurance payout with all additional costs beared by the satellite manufacturer and their suppliers.

Viasat Shareholder Letter: Q2 Fiscal Year 2024 Financial Results

Our satellite manufacturer and antenna supplier have made significant progress in determining the root cause of the ViaSat-3 F1 deployment anomaly. The rest of the spacecraft and payload are performing nominally, or better. Detailed analyses of the antenna status indicate we can obtain sufficient bandwidth, speed and coverage, combined with our existing and planned fleet, and partner space resources, to support our growing global mobility business. Even at less than 10% of its original design capacity, the design of ViaSat-3 F1 allows its available capacity to be allocated flexibly across an expanded coverage area. The anomaly does significantly impact the U.S. residential fixed broadband business, which will remain a smaller portion of current revenue until new capacity can be allocated. Eventually ViaSat-3 F2 or ViaSat-3 F3 will replace ViaSat-3 F1 over the Americas given the opportunities in that market, and the combination of ViaSat-3 F1 with the space assets available in other markets. The ViaSat-3 F3 antennas use a different design from a different supplier. It has a launch contract for the fourth quarter of calendar 2024 (about 1 year away) and is not affected by the anomaly. We expect the ViaSat-3 F1 anomaly investigation will conclude next week and will include recommended corrective actions for ViaSat-3 F2. The details of the corrective actions will drive the launch schedule. We expect to file insurance claims for both ViaSat-3 F1 and Inmarsat-6 F2 before the end of calendar 2023.

Boeing made a FCC permit filing for a satellite payload checkout at the Cape for a ULA flight, maybe it's for this?  Time period of the permit is first half of 2024.

According to the NSF US launch thread. The only non DoD, NRO & NASA launches in the first half of 2024 for ULA is Viasat 3.2, Cargo Dreamchaser flight 1 & maybe a Kuiper deployment flight. So it probably is the Viasat 3.2 comsat.

Definitely fits since the ViaSat-3 family uses the Boeing 702 satellite bus.
