Please God not Skyhook - an idea that makes even Rolling Vertical Landings look safe and well thought out......
Apart from being well past barking, would you really want to fly under something in poor viz or at night within 20-30ft of a ship that (because its relatively small) is moving significantly and only 20ft or so over the oggin? Also has the minor drawback of completely compromising the topside design of the ship and diluting the economies of scale you get with a proper carrier. There's a reason current DD/FF are much bigger than their predecessors - and it ain't stability. Skyhook-type thinking leads inevitably towards even bigger ships that will look even more costly.
Last heard of round about 2004 with a bloke from BAE suggesting it might form the basis of a solid RAS system for transferring containers full of vittles etc between ships. One system on each ship swapping the container somewhere over the sea between them. Why did'nt that catch on....?
As for SCADS I have the brochures BAE produced lurking somewhere in boxes - the only time it came anywhere near reality was RFA Reliant whose hangar I gather was somewhat less than weathertight, although at least we had a helicopter carrier for a couple of years after Engadine before Argus was converted.
