If they add one more level to their payload dispenser they could launch 44 sats on each of the five remaining flights (both F9 and GSLV)
So how many satellites would be on each of the two GSLV launches?
TOI In a first, GSLV-Mk3 to be used for commercial launch, April 26
QuoteThe source, while pointing out that a GSLV-Mk3 can put into orbit many more OneWeb-class of satellites (roughly around 30) in one launch compared to the PSLV (roughly around 6-7), said: “...But the exact number of OneWeb satellites the first Mk-3 mission will carry will be firmed up at a later stage.”

Is there a official statement that OneWeb booked 3 full Falcon 9 launches? Maybe only 2 and a half? 2 launches with up to 64 satellites and one launch with up to 32 satellites.thoughts:Arianespace/RUAG ( "Beyond Gravity" ) supplies the dispensers.There is a large one for max. 32 satellites and a small attachment for max. 4 satellites.Two stacked dispensers can accommodate max. 64 satellites. This results in ~10.5 t. Could the Falcon 9 lift that at Cape Canaveral to ~450 km, 87.4 deg?The 3rd launch with only one dispenser and max. 32 OneWeb satellites could also carry 5 Iridium satellites with dispenser. all in all ~10 tThe inclination of OneWeb and Iridium is almost the same.max. 160 OneWeb satellites are possible, 4 x Soyuz = 144, so you could omit a few, if the payload mass is too high

The OneWeb flights are out of the Cape if I remember correctly while Iridium-9 is out of Vandy.

Arianespace is supporting OneWeb on its upcoming launches; including the performance of Dispenser Supply Services for two launches to be performed by NewSpace India Limited, part of Indian national space agency ISRO.
OneWeb and Arianespace signed an agreement following the suspension of the launchesQuoteArianespace is supporting OneWeb on its upcoming launches; including the performance of Dispenser Supply Services for two launches to be performed by NewSpace India Limited, part of Indian national space agency ISRO.That's an interesting statement. Different dispensers for the SpaceX launches?
A SpaceX Falcon 9 rocket will launch 40 satellites into orbit for OneWeb, which is developing and deploying a constellation of hundreds of satellites in low Earth orbit for low-latency broadband communications. This will the first launch of OneWeb satellites with SpaceX. The Falcon 9’s first stage booster will return to Landing Zone 1 at Cape Canaveral Space Force Station. [Nov. 2]
I note LC-39A may be available after SpX-26, currently scheduled for launch on November 18, and January 2023.Unless there is Starship construction work?Edit to add:Nov 1 FH USSF-44Nov 18 F9 SpX-26<nothing scheduled; Starlink(s)?>NET Dec 27 NET Jan 4 FH ViaSat-3 AmericasJan 10 F9 SpX-27Jan (or Dec 2022?)

Isn't this a polar launch? I thought those were only possible from SLC-40 and SLC-4E.
