055 Large Destroyer Thread II

[LanceD23]

An educated guess must be based on observable facts. You have none and I have none. We can see a new radar being field tested. My educated guess is that this radar's technologies are at the same level as the KJ-3000. Both probably finalized years and years ago. Like the points raised by others above, 055 is a relatively new ship and using a newer generation of GaN is even more plausible and practical. Given the slow speed of USN developments, future threats to PLAN ships will not appreciably change in the next decade. At this point, both quantity and maturing the current CEC are more useful. I don't see the need to rush at all. Ships are expensive toys and just like the USN, PLAN must have their own long term wish list and build schedule that we are not privy to. Just like the larger gun that we also have seen, I am sure lots of full time researchers in China are exploring GaO and all the complementing battle management/kill chain technologies/nodes today but we don't know their priorities and trade-offs.

its already reaching mature stage of 8 inches from beginning 2 inches. Many years of advancement.

right now you can say we have none direct evidence but people are abusing this old cliche of no direct evidences as to cover their ground or ignorance.

but come on, common sense. Things you can see miles ahead. just like intranet in military and at the time people already see internet on the commercial level. They dont have direct evidence at the time, but people know its gonna to happen.

what's stopping it from happening? do you have evidences that will prevent it from using on naval ships?

The tech is starting to mature.

you may have a point if they just break into this tech at the beginning.

this supposedly testing gallium oxideradar on experimental ship.

8 inch gallium oxide wafers do not by themselves confirm that the technology is already being adopted for the next iteration of ship radars.

Once again, you are free to speculate. But presenting your speculation as confirmed facts is misinformation.

do you have any evidences yourself? I think you try to mislead.
In the court, both sides have to present evidences. Not just one.

I don’t need evidence to show something isn’t happening. You need evidence to show that something is happening. In both the court and science there is a concept called evidentiary standards. If you have to play meaningless word games to try to burnish your credibility you might as well just admit that you’re BSing. Either you have sufficient evidence or you do not. Please exercise basic intellectual standards. Our desired goal in this forum is to get the facts right, not to play cheerleaders.

Please stop posting this low effort drivel. This is not a thread for that.

try to present some new tidbits but ended up arguing with bunch of boneheads,

You have add zero useful information to the conversation and don't even have the grace to be quiet when your nonsense is called out.

How about you stick to making wild claims that Zhang Youxia has just deposed Xi in a coup and leave the flagship threads to the sane folks?

Official Xi Jinping Thought discussion thread

why not? like i said, you look at past leaders, even the best ones, have all messed this up. does Xi recognize this risk? I am certain that he does, but it doesn't mean that he can avoid it. Mao and Deng were all extremely cognizant of the succession question, neither of them did a great job on...

Two nice images of DDG 102 and 107.

Gallium Oxide has poor heat conductivity. Is it suitable for high power applications like T/R modules of radar?

Theoretically yes, but you need a better substrate for heat conduction. It has been tested with synthetic diamond substrate in lab conditions I think, but that poses other difficulties. Overall its a tricky engineering problem but probably not insurmountable.

Self-explanatory.

Gallium oxide is significantly superior to gallium nitride in terms of

, with gallium oxide having a critical field strength more than twice that of gallium nitride. Gallium oxide's ultra-wide bandgap also contributes to its superior performance.

Gallium oxide has its strength, but also has disadvantages like poor heat conductivity making it challenging to be used in high power applications like Radar. No material is magically superior to other materials in all aspect. There are still a lot of technical challenges to overcome for it to be used in radar.
