Here's the orbital stuff if anyone was wondering: - "That funding will go towards the development and launch of satellites in three orbits. Eighteen satellites will operate in medium Earth orbit (MEO) at an altitude of 8,000 kilometers, providing Ka-band services. A “LEO High” shell at about 1,200 kilometers will include 264 satellites with Ku- and Ka-band services. The system will also include 10 or more satellites in a “LEO Low” shell between 400 and 750 kilometers intended to support incubation of future technologies. " and - "The next step for IRIS² is a one-year design phase that will also include “consolidation” of the supply chain of contractors for the satellites. A critical design review is planned for early 2028, with launch of the satellites projected to take place in 2029 and 2030. The constellation will require 13 Ariane 64 launches, 10 for the LEO High shell and 3 for the MEO shell." https://spacenews.com/europe-signs-contracts-for-iris%C2%B2-constellation/ https://spacenews.com/europe-signs-contracts-for-iris%C2%B2-... ("Europe signs contracts for IRIS² constellation") (Put together, you can constrain the mass of the satellites as <820 kg: for the LEO-High shell, 10 launches of A64, at a maximum of 21,650 kg each, divided by 264 units. That'd be intermediate between v1 and v2 Starlinks).
