The USAF did ski jump tests in 1983, http://www.dtic.mil/dtic/tr/fulltext/u2/a237265.pdf, and concluded that F15 and F16 at gross combat weights would reduce take off run by 50% with a 9% ski jump. The USN also did ski jump tests and I think found a ski jump beneficial, but obviously not enough to make the switch from catapults.
The SU33 had thrust vectoring nozzles and canard foreplanes so can make better use of a ski jump that a teen series fighter. I've also seen it written that a Eurofighter if fully controllable at 90kt, so could conceivably land on a carrier without wires, presumably with thrust vectoring it could make use of a ski jump as well.
Why not a hybrid approach using catapults and ski-jumps?
