    Chinas third aircraft carrier, the type 002, (first carriers in the fleet are the Type-001 and Type 001A based on the Kuznetsov class) is starting to take shape.

    The new carrier is rumored to be an conventional powerd supercarrier with 3-4 Electromagnetic Aircraft Launch Systems (catapults) with an estimated displacement of about 85.000 tons and lengh of over 300 meters making it about the same size as the US Kitty Hawk class carriers.

    Launch date is 2020 with a possible commissioning in 2021-2022.

    What's the point of a conventional propulsion for such a big ship ?

    Several reasons I would asume. First is probably that China dont have any reactors ready for these kinds of vessles yet and they dont want to wait with building up its carrier fleet. Type-003 suposely will be nuclear powered.

    They have the one step at a time philosophy.
    Makes sense if you have virtually limitless resources and you split production in two phases, a developmental and an exploration.

    The speed of construction is amazing....I wonder if they really have reliable EMALS tech. The Americans seem to be skeptical

    Apparently thet tested both electromagnatic and steam driven systems and decided that EM was the way to go. Im sure problems will come up like in all new systems.

    They would have problems with steam technology anyway, so it just makes sense to work on the newer technology where the skills will be much more useful and the new technologies applied all through an enormous range of areas.

    It would be naive to think there wont be problems with EMALS, the the value of getting a working system and solving all those problems with new techniques and new technologies makes it very well worth it.

    Most countries are looking at all electric drive vehicles from motorbikes and cars to buses trucks and trains and unmanned vehicles of all types as well as aircraft and ships, so the technology is going to be useful across the range of vehicles.

    They will be in the same position as the Russians that their fighter planes will probably be able to take off without them, but it will mean much more capable AWACS platforms can be used which makes the ships safer.

    The drone attack on Saudi Arabia shows rather clearly that you can have all the best high tech air defence missiles and guns systems, but if you don't know you are under attack until the explosions start you are already screwed... and there is no dollar value of SAMs that can save you then.

    Carriers are not cheap... even the small ones are expensive, so the last thing you should do it make them more vulnerable by giving them half arsed situational awareness. A helicopter based AEW is much better than nothing, but if you are building carriers with cats you should be at the very least looking at a Hawkeye type aircraft and these days perhaps something even better...

    Will be interesting to see how they go with this... it does not hurt Russia for China to have a strong capable navy and it will give China more options to protect its investments in far away places when the US steps in and talks about regime change. A Chinese aircraft carrier and a few destroyers and a cruiser or two going to Venezuela for a peaceful exercise would be an excellent way for China to tell the US to pull their heads in... they don't need to invade or bomb anyone, though they certainly could if they needed to.

    Steam powered cats did the job, but it was expensive and dangerous and not super modern.

    Basically you set the pressure based on the aircraft and its fuel and weapon load... if you got it wrong the aircraft would not gain enough speed and would end up in the water for a low setting, or have its nose wheel ripped off if the setting was too high.

    With an EM cat... as it accelerates the aircraft it can determine how it is doing and increase or decrease the energy to ensure it gets to a takeoff speed.

    There is flexibility. And also concentrating electrical energy and moving it around... it is a bit like Star Trek... energy to main launchers, then energy to shields etc etc... with these new electric ships electricity management is going to be important and storing it and generating it when needed is going to be critical.

    It is going to compliment EM weapons and perhaps EM camouflage and EM shielding too... not to mention other energy weapons and EM related systems.

    You could even develop a "catapult" system that can accelerate projectiles to enormous speed as a sort of gun replacement.

    Instead of accelerating a 30 ton aircraft to 200km/h or faster for take off, how about accelerating a .1 ton projectile to 2km/s with a built in scramjet motor so it not only maintains that speed but actually accelerates in flight, with a built in GLONASS guidance system with steering vanes to get within 5m of any target.

    Save an enormous amount of rocket propellent, which is not cheap.

    Keep in mind that on any ship there is a risk of fire, so not carrying propellent charges for gun rounds and not carrying missiles with solid fuel rocket propellent makes the ship safer and makes handling easier... effectively you just load the warheads when you resupply.
