> Europe having Ariane 6 and Vega rocket for example make no sense. They could have one engine...

It absolutely makes sense, Vega is basically an Ariane 5 solid rocket booster that was turned into an actual rocket, both are/were made by Avio who now make the Ariane 6 boosters.

And yet if you actually go and look at the cost of the Vega series of rockets its very expensive. Just using the same expensive stuff multiple times doesn't make it a good policy.

And then you keep reading and realize that Vega is not just a solid booster, but a 4 stage rocket.

They should’ve skipped Ariane 6 and do Ariane 5ME instead and make the next vehicle a reusable one. Ariane 6 doesn’t really buy them anything more than Ariane 5ME, just buys more risk and more development cost (this latter thing may actually have been the unstated INTENT of some stakeholders…).
