CV-18 Fujian/003 CATOBAR carrier thread

I got a question. Can the 003 support aerial refueling tankers? Maybe one that is similar to KJ-600?

It will be really helpful if 003 can help extending the combat range of land-based planes in case of an A2/AD operation.

Don't see why it couldn't.

Most likely, we will see a number of drones as well on the 003, which could very well include something like a refueling drone.

Heck, we all forgot that Taiwan, Hong Kong and Macao are also costal and provincial level.

So we have Tianjin, Hebei, Jiangsu, Shanghai, Zhejiang, Taiwan, Guangdong, Hong Kong and Macao left. That's 9 of them.

But again they don't have to be costal. I think Chongqing, Hubei, Hunan may get one, or at least a 075.

Yes, but only aerial refueling drones, like the MQ-25.

Aerial refueling tankers like the HY-6D and newer Y-20U would never be able to fit on the 003, let alone operate from it.

Besides, there has been no plan for an aerial refueling version of the Y-7 (of which the KJ-600 is derived from).

In 2003, Ma Weimin along with his team, ventured into trying to make “船舰综合电力技术国防科技重点实验室” (National Defense Science and Technology Key Laboratory of Ship Integrated Power Technology), and he was the first in the world to propose as well as actually make and implement 中压直流综合电力系统 (Medium Voltage DC Integrated Power System), technology which is ahead of the world by about 10 years, and which is also something such as the US, have pivoted to/are researching.
This technology, has basically allowed China to go from being behind, to being in front, when it comes to the technological area of ship propulsion.

In my opinion, I don't think this part tells the whole story. How did they determine that China is 10 years ahead? If China mastered MVDC in the early 2000s then according to this interpretation the West should already have had mature MVDC technology, which as far as I know is not the case.

I used to be convinced that China had the lead on MVDC, but through the years my conviction has faded away. If they had this technology 20 years ago why haven't we seen any PLAN combatants employ it? In the meantime, the West has been building full electric warships with MVAC grids since 2003 (Type 45 destroyer) and LVDC warships since 2011 (Zumwalt). Not to mention the multitude of commercial LVDC ships designed and built in the West in the last 15 years.

At this rate, by the time China fields a MVDC ship the advantage over the West will be far less than the alleged 10 years. How depressing.

From the interview with Ma Weiming by global times in 2017

环球时报：美国首艘采用电磁弹射系统的“福特”号航母花了21年时间才完成从研制到应用的过程，中国也需要这么久吗？
Global Times: It took 21 years for the USS Ford, the first U.S. aircraft carrier with an electromagnetic ejection system, to go from development to application. Will it take China that long too?

马伟明：只要方向正确，方法得当，那么进程可以大大缩短。
Prof. Ma: With the right direction and the right approach, then the process can be shortened considerably.

环球时报：美国“福特”级航母的经验显示，航母的电磁阻拦技术比弹射难度更高……（没问完的是中国是否有这方面研究）
Global Times: The experience of the US Ford class carriers shows that Electromagnetic arresting system for carriers is more difficult than catapulting ...... (what is not asked is whether China has researched this)

马伟明：不能这样下定论。我们用了1/5的时间就把阻拦做完了，你说哪个难度高？有了弹射的技术阻拦还难吗？弹射和阻拦是一个正一个反，解决了正，解决反不就容易了吗？
Prof. Ma: Can't come to such a conclusion. It took us 1/5 of the time to finish the blocking. Which one is more difficult? Now that electromagnetic ejection system has been developed, will it be difficult to develop Electromagnetic arresting system? (it's difficult to translate properly “正” “反” for me, anyone can help?)

环球时报：现在军舰上大量采用电气设备，特别是新一代采用全电推进系统（IEP）、电磁轨道炮和电磁弹射/阻拦设备的军舰，如何防止因对手引爆电磁脉冲炸弹导致完全失去战斗力？
Global Times: At present, modern warships use numerous electrical equipment, especially the new generation of warships using all IEP, electromagnetic rail gun and electromagnetic ejection / arresting equipment. How can we prevent the enemy from completely losing combat power due to the detonation of electromagnetic pulse bombs by the opponent?

马伟明：这个问题不太专业。脉冲弹是靠辐射，舰船全是铁壳屏蔽的，很难影响到内部系统。它又不是陆地大电网。另外谈到中国的综合电力，我们全（推进系统）是处于世界领先的位置。我们（技术）是中压直流，一步到位。美国目前是中压交流，还处于第一代水平，差我们一代。（他们目前）才开始做预研中压直流，要赶上我们是十几年以后的事情。（一项技术）领先不领先，先进不先进不是自己说的，需要世界同行评价，标准是客观存在的。
Prof. Ma: This is not a professional question. Pulse bombs rely on radiation, and ships are shielded by iron shells, which is difficult to affect the internal system. It is not a large land power grid. In addition, when it comes to China's integrated power, our IEP is in the leading position in the world. We (Our technology) are medium voltage DC, reach the goal in one step. The US is currently on medium voltage AC and is still at the first generation, a generation behind us.
At present (2017), they have only begun the pre research of medium voltage DC, and it will be more than ten years before they catch up with us. Whether a technology is leading or not, and whether it is advanced or not, is not self-evident. It needs to be evaluated by the world's peers. The standards exist objectively.

I like Professor Ma's directness and non-nonsense answers. Also he basically answered the question that if 003 uses electromagnetic arresting system. Answer is yes.

Can someone explain what is the function of the highlighted circular protrusions? They are not visible on the starboard side.
