Give me a STOVL that can travel to Mars and back in 3 minutes. Why list a random requirement?
The requirements aren't random. That's why SVTOL fighter jets (or literally anything that are man-made) exist in the first place.
"I am asking why the your mission requirement is relevant to justify STOVL over J-35 and helicopters."
And you have yet to justify it. I gave you time of 3 posts and you still can't do it. I will repeat this as many times as I need to.
And before anyone who say J-35, helicopters, STOVL are apple to oranges that cannot be compared, sure they can. Any resources spent on them is one less for other 2. They all require shared deck space. They require limited amount of skilled personnel. They compete in production and budget, and having more complicates logistics. They compete against each other. Not apple to orange at all. And before you say "no, STOVL require no EMAL" it is no longer a problem. China solved it in 076 even marines get access to those. So why do you need vertical take off and the compromise it entails? To save money on EMAL?
(Note that all the discussions here are about the Navy side of things, i.e. operating from LHD/As.)
To start with:
S/VTOL fighter jets are simultaneously equipped with the capability to operate from and to short flight decks that are located within vicinity to the warzone (the carrier-based J-35 and land-based J-35A couldn't), able to provide rapid responses to the warzone (the carrier-based J-35 and land-based J-35A couldn't), have LO capabilities (helicopters don't), can fly at Mach 0.8 - Mach 1.6 and at 30-50 thousand feet (helicopters couldn't), and are able to conduct both A2G and A2A missions using the same airframe (helicopters couldn't), to state a few.
Of course, there are also reasons related to the operational and strategic aspects of things that would justify the existence of a SVTOL jet. For instance:
"Just build more carriers man" - How long does it take for proper CVs like Fujian from laying down the first pieces until declared IOC/FOC? And how long do LHD/As take to go through the same process? Plus, how much money, manpower and resources does each of these costs to design, build, operate and maintain, respectively?
"Just send the carriers man, they'll do the job" - What if the carriers (which are actually more limited in numbers and availability than LHD/As) are also needed elsewhere and won't be available to provide support?
"SVTOL jets only compete production slots and budget, complicate logistics and operations duh" - There are always cases and scenarios where money, manpower and resources have to be spent in order to achieve the required capabilities deemed crucial by the higher ups of the PLAN, of which they deem cannot be effectively fulfilled by other assets that are already available to the PLAN. In fact, such situations do apply for the other branches and arms of the PLA as well.
Not that I'm supporting or refuting the importance and necessity of having V/STOL fighter jets in the PLAN (both sides of the argument have their own merits) - But there certainly are pretty good reasons for BOTH the higher ups of the DoN and the PLAN to go "Yeah, we should dedicate X amount of our money, manpower and resources towards developing (and operate) this thing."
So if you are unhappy with what the PLAN is doing, AND you believe that you do know better than everyone else in the PLAN - Instead of ranting about it here in this forum,
how about you go to the August 1st Building and voice your objections to the higher ups of the PLAN over there?
