Earliest gas turbine

CVA -01 with 6 Olympus would give 139,200shp. Slightly more that the steam turbines as designed (135,000shp)
Aircraft designed early 50’s would be the 62,000lbs Buccaneer.
Early 60’s the benchmark F111 was bandied about with the F111B coming in at 88,000lbs. A lot of power required to launch that beast. The F11B was cancelled but so to was the CVA01. Would the 250 ft catapults receive enough steam power for these?

The cancellation of the F111B had nothing to do with the UK killing CVA-01. It was killed because the USN absolutely hated the plane, had been forced into choosing it by a hostile SECDEF, and it was completely FUBAR. So CVA-01 never would have had to worry about launching one. However, if it did, then yes. It could have launched one with a catapult with a 250' power stroke.

The Olympus in the Bristol had 22,000shp, so 6 of those is 132,000, close enough to the steam power. However the big thing is the requirement for long refits to rehabilitate steam powerplants, which is why prior to GTs ships were available only 2/3 of their lives whereas GT ships are available 3/4-4/5 of their lives. To a large extent this means that with GTs the RN could get away with only 2 CVAs as both would be available 3 years out of 5.

The RN aren't going to buy a strike version of the F111B (it was a missile interceptor) in 1968 when they had already bought strike aircraft 3 years earlier, they won't be in the market for a strike aircraft again until about 1985.
 
The first RN County class destroyer with COSAG power plant was commissioned in 1962, 30,000 hp steam and 30,000 hp gas turbines. Double the power plant for a carrier gives you 120,000 Shp. in the early 1960's
 
The problem with the County installation was that the Metrovick G6 gas turbines were comparatively low powered, which meant a complicated gearbox setup to handle two gas turbines per shaft. That is why I suggested the Gyron, which would give a much simpler gearbox due to it putting out more than double the power. Apart from that I agree totally. The 60,000 shp steam plant should give ample power for the catapults while the gas turbines take care of motive power.
 
Olympus TM2 23,200 each = 139,200shp.
Never suggested that the RN was for getting the F111 but that was the size of aircraft the pipe dreamers were banding about.
