And if that is not only theory but daily practice, why the Chinese are planing for a CATOBAR-carrier?
I'll repost a previous paragraph that I've written before:
"I believe what catapults offer is the ability to more reliably launch heavily loaded fighters under a variety of conditions (including minimal head wind) as well as if a fighter's engine fails during a launch, thus making a catapult safer and more flexible in launching fighters compared to ski jumps.
Catapults also of course are the only reliable way to launch aircraft like fixed wing AEWC, which a ski jump likely cannot do.
Catapults therefore offer a far greater margin for safety and flexibility when launching heavily loaded planes than ski jumps, but that does not mean ski jumps cannot inherently launch heavily loaded planes"
In other words, if we want to compare the most obvious advantages of a CATOBAR vs STOBAR carrier, it is probably not a simple case of:
CATOBAR:
-can launch heavy strike jets
STOBAR:
-can't launch heavy strike jets
And it's more like:
CATOBAR:
-can launch heavy strike jets under a wide variety of conditions in a reliable manner (such as including an engine failure on a twin engine jet)
-can reliably launch fixed wing AEW&C
-other benefits such as increased bow deck area for parking planes, relative to a STOBAR carrier
STOBAR:
-can launch heavy strike jets under some conditions with sufficient wind-over-deck but cannot launch in as wide variety of conditions as a CATOBAR ship
-can't reliably launch fixed wing AEW&C
-reduced bow deck area for parking planes
I appreciate that everyone, especially media, likes to simplify things down, so we end up with mantras like "jets launched from ski jump carriers can't conduct strike missions because they can't take off with heavy loads," but in reality it's probably a far more nuanced situation than that, and it's probably better said as "jets launched from ski jump carriers can conduct strike missions if they are launched from the ship under the right conditions, however the conditions for launch are more stringent than a catapult carrier including with likely greater risks for fighters if they experience engine failures during launch".
Unfortunately the second sentence doesn't look as snappy on paper...
Take all that together, and obviously it is logical for why the Chinese Navy would want to move towards CATOBAR carriers, because a reliable CATOBAR carrier still offers greater all around capabilities and flexibility than an equivalent STOBAR carrier.
