I somehow doubt OneWeb is getting those satellites launched or even back.
Russia must be running out of feet to shoot itself in. Who would ever be dumb enough to contract their services after this?

Putin is obviously mad, there is no reasoning with such a person. The Russian people need to rise up and regain their freedoms. The madman is destroying their future.

The Russian space program has been dangerously underfunded as it is. Scaring off commercial customers is just going to compound their problems.

They have already "fully paid" for all scheduled flights for this year. It will be a huge write off for all but Russia as Russia doesn't tend to provide refunds. OneWeb can either appease tothe Russian demands for each flight or forfeit the remaining flights and accept the losses.

There is not enough willing to do so to risk there own/family's lives and outnumber the hit teams and Russian forces that end such attempts.

So if those further five launches are at least $50M each (discounting the S/C value still in their power) as a conservative assumption, in the event this does not de-escalate soon they're looking at at least $350M immediate loss.

Is it common in the launch industry to pay in full upfront? I would never let a contractor in my house with those terms!

A large part would be paid upfront to cover build cost of LVs.

The monetary value is the least of OneWeb's problems. Their insurance may even cover it, or the contract with Arianespace. Hell, you could find the UK government just takes part of the money from Russian funds (risky).

The bigger issue is the complete collapse of OneWeb which is a devastating blow to the UK's and Europe's hope for a non US system. It could basically mean starlink becomes the only system out there, or it and Kuiper.

The world really needs a non US competitor.

Now that the US has also closed its airspace to Russian planes,
I don't see any way more OneWeb satellites could come to Baikonur.
The transport containers were previously transported by AN-124 from Volga-Dnepr Airline.

Their US subsidiary in Houston, where their US Subsidiaries headquarters and operations center is, may end up with grounded planes. I have not verified if any of the airlines aircraft remain in the US at this time.

That will be China.

I would think there are options for launching the bird. India or perhaps SpaceX. India has had rocket issues lately and SpaceX is a competitor. But both are options if you want to continue building out the constellation. If the UK really wants it to happen they could make it happen, but it will cost more.

Sorry if this is an off-topic question, but who will most likely cover loss (in the case when Roscosmos doesn't launch or return the money)? OneWeb, Arianespace as a launch provider, or an insurance company?

Russia likes the no refunds playing card if the launch is cancelled. Happened to Ukraines' Lybid Satellite and others. So depending upon the wording of the insurance policy in in conjunction with the other involved parties. Russia as a whole including reportedly the common people are blocked from sending and receiving funds so it cannot transfer anything.

I assume that would be specified in the relevant contracts.  However, force majeure could be invoked, in which case it will probably be tied up in litigation for a while.

Complete collapse of OneWeb? That's hyperbole. Yes, they'll probably end up losing some fraction of the ~$350M for these launches (the fraction that went to Roscosmos), and yes this will delay them being able to launch their remaining ~200 satellites. But they already have over 2/3 of their constellation launched. As of some point last year (I think August or September), they hit the point where once their satellites were done with orbit raising, that they could begin offering commercial services above/below 50N and 50S. With the number of launches they've done since then, I wouldn't be surprised if they could extend that to 40N/S or maybe even 30N/S with some cleverness. Is that the whole world? No. But depending on the minimum latitude they can serve, that could still be most or all of Europe, Canada, the US, Japan/SK, parts of China, possibly northern parts of India, parts of Australia, NZ, large parts of South Africa and South America.

I guess I'm just saying that I wouldn't count them out yet.

Sorry, but that's not how it works. For a constellation like OneWeb whose satellites are in near-polar orbits, You get continuous coverage at latitudes higher than 50 once you have populated half your planes. Below that latitude, you have coverage gaps between  every plane and the gaps are an increasing percentage of the total time as latitude decreases, until you only have coverage half the time at the Equator. Incremental increases in number of satellites doe not result in a progressive lowering of the continuous-coverage latitude unless you spend a lot of fuel to do plane changes in existing planes as you add planes, and that is simply not feasible.

A decent fraction of their satellites are still in orbit raising maneuvers, which means that if they're clever about pausing their orbital raises and letting differential nodal precession do its job, they can spread them out into more planes for a negligible fuel cost, but extra time. I haven't run the numbers, but I wouldn't be surprised if they could still salvage something if they wanted to.

(Edit: I have spreadsheets somewhere for calculating differential nodal precession at various inclinations/altitudes, but I decided to ping a friend with better tools to get his take--admittedly, now that I remember, you don't get *that* fast of differential nodal drift in their near-polar orbit).
