Right now I believe the max VL landing specs are 3,000ish pounds of unexpended munitions + reserve fuel SRVL adds another 2,000ish pounds on.
The idea is the plane is going 30 to 40 knots when it lands not the 180+ controlled crash that a normal carrier landing is. I don't get what all the worry is about if the brakes can't stop the plane at that speed then all versions will be running off the end of the runway and stacking it. Ultimately there was a bunch of money put aside for it but I don't think work starts in earnest for a while (until next year, maybe?).
Anyway most of time the planes won't have any weapons aboard as we can't afford it so it'll be fine!
I'm sure someone will be along with all the public domain diagrams and articles soon.
