It will be joined by two other satellites: Syracuse 4B launched in 2022 and Syracuse 4C ordered by 2025.

Syracuse 4B
...

@zubenelgenubi your link goes to Syracuse-4A, the satellites are not identical.  ;)
VA258 ?
CNES writes there (date March 23, 2022) launch Syracuse-4B mid-2022.But with which co-passenger?
Eutelsat Konnect VHTS is maybe 3 months away from a possible launch, I believe. But he is very tall and heavy.
Is Syracuse 4B small and light enough to partner with?
Eutelsat 10B payload+platform mating was about 5 months after Konnect VHTS mating. So it won't be finished soon.
Eutelsat Hotbird 13G (or 13F) no current information on these satellites.  :(

Cross-posts.

Given that it takes approximately two weeks minimum to turn around between launches from Kourou/Ariane 5 launches, then NET late September is the earliest that Syracuse 4B could launch aboard a hypothetical VA259, with a more massive copassenger.

The above is no guarantee.  It could be the less massive copassenger on VA260, even later in 2022, or early 2023.

@orange SAT teams were able to admire a monster: the new VHTS Konnect from @Eutelsat_SA the biggest European satellite ever built by @Thales_Alenia_S and in which we have heavily invested: 8.8 m high, 6500 kg and 40 m wide with solar panels.

It will enter the test phase then will be transported to Kourou by boat in early July, launched by an Ariane 5 in September and will be operational in August 2023.

It will be launched by an Ariane V (flight VA258) like this one, which I photographed on its launch pad at the Guiana Space Center in Kourou during the launch of the intelsat EPIC 33e.

Yes [Eutelsat Konnect VHTS] is the only payload on VA258.

https://twitter.com/Eutelsat_SA/status/1534220775837913090

During the VA257 launch webcast:
Israel: VA258 launches on September 6.

So after this tweet:

And mark your calendar: we’ll be back early September 6 for next Ariane 5 mission: onboard, EUTELSAT KONNECT VHTS, a satellite built by Thales_Alenia_S for Eutelsat_SA! VA258.

As of this post, there is no news of the completion or delivery of Syracuse-4B.

Also, there is no news of the launch times or payloads assigned to VA259 and VA260.

The NET late September launch was based on the minimum turn-around after VA258 launches on September 6.

Also, the amount of time it takes to process a spacecraft for launch on-site at CSG must be considered.

Launch would now be NET Q4 2022.

CNES writes in the Annual Report 2021, 2022 highlights: "End of year, Launch of Syracuse 4B by Ariane 5.".
I do not know why the report is published on August 24, 2022 and how up-to-date this information is.

I merged the launch threads for Syracuse 4B and Ovzon-3: They are the two remaining geocomm satellites launching aboard Ariane 5.

Re: Eutelsat 10B:
SFN confirms this is also switching to a Falcon 9 launch from SLC-40 at the Cape, NET November 2022.

Also "The Falcon 9’s first stage booster will either be expended or land on a drone ship in the Atlantic Ocean." - probable last usage of B1049?

If this thread is for a flight that Ovzon isn't on, then the Ovzon news doesn't belong in this thread.

Syracuse 4B seems to be ready for a launch, when the launcher (co-passenger?) will be ready, is not yet clear.
That's how I understand it.

Syracuse 4B, Heinrich Hertz, and Ovzon-3

Is there an adapter on SYLDA, or on one of the other two satellites, to accommodate Ovzon-3?

That tweet is from 28 September, nearly two months ago. However, its not looking good for Ovzon 3. Even the regulators can't get information from Ovzon!

https://www.spaceintelreport.com/regulators-refuse-extension-of-ovzon-3-satellite-in-service-deadline-pending-manufacture-launcher-documentation/

"17 November 2022 International regulators declined to grant Sweden-based Ovzon AB an extension of the December in-service deadline for the Ovzon-3 satellite until the company provides much more detail from the satellite’s builder and launch-service provider explaining the delivery delays and the new schedule.

Acting through its regulator, the Cyprus Ministry of Research, Innovation and Digital Policy, Ovzon is asking regulators to view Ovzon-3’s delays as a force majeure case eligible for deadline extensions."

This recent article doesn't mention Ovzon 3 being along for the ride.

https://www.spaceintelreport.com/germany-wins-regulatory-ok-to-heinrich-hertz-satellite-launch-in-june-on-last-ariane-5-with-french-military-syracuse-4b/

"17 November 2022 The German government has won  regulatory approval for a 2.5-month extension, to July 15, of the deadline for launching its civil/military Heinrich Hertz satellite, H2Sat.

The new date should give Germany and the H2Sat prime contractor, OHB SE, time enough to wrap up environmental testing of the satellite for shipment to Europe’s Guiana Space Center spaceport by April 17.

Under this schedule, it would be mated with the French Defense Ministry’s Syracuse 4B"

Global MilSatCom 2022: French Syracuse satellite confirmed for launch in 2023

by Olivia Savage

...

Speaking at the Global MilSatCom 2022 conference and exhibition held in London between 8 and 10 November, Lieutenant Colonel Marina Ballanger, Satcom International Affairs at the French defence procurement agency (Direction générale de l'armement: DGA), announced that the launch date for the Syracuse 4B satellite has been confirmed for early 2023.

Development of the satellite is expected to be completed by December 2022, and ready for its launch date in early 2023, she said.
...

I thought Syracuse 4B was already ready to launch. Now it's clear, why Eutelsat has rebooked the 10B to the Falcon-9.
Syracuse 4B on the other hand, will have to wait for its launch partner(s?).
These double launches are a handicap for Arianespace.

This is obviously a STA request for the LEOP of H2Sat (Heinrich Hertz), originally starting on March 3rd for 180 days.

There is another letter from January 13, the period will be changed.now starting on July 2, 2023.

La Tribune writes here that the launch will take place in June. We will see.
The ground segment of H2SAT is not yet ready after that article.
The French Air and Space Force, meanwhile, is pretty unhappy with how things are going with Syracuse 4B.

https://www.latribune.fr/entreprises-finance/industrie/aeronautique-defense/le-retard-du-satellite-allemand-h2sat-repousse-le-lancement-de-syracuse-4b-948096.html

With a launch at the beginning of July, there would only be 2 weeks until the 2.5-month extension for the launch of H2SAT at the ITU is over.
