m9,
The USMC Harriers operate off exactly the kind of deck shown in that video with a pretty usable war-load.
If you go to this site:
Aviation Videos & Airplane Videos | Patrick's Aviation
and search for a video called "Go Boom" you will see AV-8Bs operating from an LHA during GW2, carrying a variety of loads including large external tanks and 2 LGBs.
As I said before, I recall a Harrier pilot telling me that the CVS ski-jump speed limit has the effect of curtailing the launch speed and lowering the payload for a modern Harrier. I don't know if I remembered this correctly, or whether it is simply the extra length the USN LHAs that makes the difference, but those ships certainly seem capable operating Harriers at useful weights without a ski-jump.
