Unless I'm reading this incorrectly, seems very odd to me that they would put fuel in the fuel tanks before they transport it to the launch port - isn't that asking for trouble to have highly explosive fuel sloshing around in it during the journey

JWST propellant

That's a cool link, but I don't think it answers u/Novack_and_good's question? The answer is that no, they're not fueling it before transporting overseas:

Once Webb arrives at Europe’s Spaceport, launch processing teams will prepare and configure the observatory for flight. This involves post-shipment checkouts and carefully loading the spacecraft’s propellant tanks with fuel. Then, engineering teams will mate the observatory to its launch vehicle [...]

So it'll only get fueled at the spaceport in Guyana, right before mounting to the Ariane 5.

Thanks- I had read the article incorrectly, they only load the fuel in the Guiana spaceport, not in California- which makes more sense
