055 DDG Large Destroyer Thread

[taxiya]

Flight IIA has three 3MW GT generators, while the Flight III will have three 4MW GT generators. 20MW for the 055 seems somewhat excessive unless they are being used to power something we don't know about (maybe those huge panels?)

Thanks for the infor on Flight III. That 3x4MW makes 12MW. While 055 has 20MW, but also 2000t more displacement meaning more room for electricity generation. In this case, I don't think 055 is excessive compared to Flight III.

Yes, the huge panels can be good potential users of this extra juice if they are HPM weapons.

I don't think TerraServer has updated their imagery of JCNX. This is the shot that I just got off their site:

You have to open the date menu by clicking on the arrow icon on the left of the page, right under the search bar. Then select the latest image. The one they show you by default is from two years ago.

This is the latest image they have, dated June 11. Resolution is 0.5m/pixel and is B&W, not nearly enough to make out clearly 112 or 128. Or even 96.

Yeah.

20MW doesn't sound excessive given the larger size of the Type-55 and future requirements like railguns, lasers or electric propulsion.

 

[SpicySichuan]

Looks like it is only 96

 

[Iron Man]

Yeah.

"Future requirements" may possibly justify 20MW, but "larger size" certainly does not. Ramping up a 9.8kt ship with 12MW power capacity to a 12kt ship with 20MW power capacity represents a 22% increase in displacement but a 67% increase in power capacity. If there are 4 generators on board the 055, they should be something more along the lines of 4MW each for a total of 16MW. Either that 4 extra MW is fictional or if it is real, then it is spare power for future weapons. Either way, the size increase alone does not justify 20MW.

I don't think size alone justifies the idea of 20MW in the sense of any linear relationship that may or may not exist between displacement and power generation.

But a combination of size+role of ship/when it was designed I think does not make 20MW unrealistic.
After all the Flight III Burke has 33% greater power generation than Flight IIA Burke, yet it displaces only a few hundred tons more.


edit: putting it another way, I think "future requirements" should instead also include "current requirements". An emphasis on more powerful sensors along with EW and if it does have HPM weapons, then I think does not make 20MW seem unreasonable, which would put it in fairly good company where some recently developed ships have more power output than equivalently sized ships of a previous generation.

All you've got going for you with your "current requirements" argument is your hypothetical Star Wars "HPM", as the Flight III already has high power GaN sensors (which the Flight IIA does not have). If the 055 also has this, it still wouldn't justify an increase to 20MW. "EW" sounds like hand-waving since Flight III is sure to also have this (as does the Flight IIA), and so can do EW, GaN sensing, and in the future power the purported X-band 3-panel array, all with only 12MW installed power. What else can you throw in there for the 055's "current" requirements?

Yes, basically I'm suggesting that 055's combined sensor+EW+potential HPM weapon put together could require power output of say, 20MW.

If we use Flight III Burke's 12MW benchmark as a guide for the kind of sensors/ew it has, it is another way of suggesting that the 055's sensor+EW+potential HPM weapon put together (or individually) have higher power requirements than the Burke III's systems.


I'm not saying 055 definitely has a power output of 20MW, I'm just saying that it's not an implausible number. Considering how little we know of 055's electronics outfit, that gives us a lot of logical space for hand waving and open speculation to try and justify how or why they may want 20MW.

Like I said, the ONLY thing you have going for you is the hypothetical "HPM", as both GaN sensor and EW is ALREADY present on the Flight III Burke and it only requires 12MW. So please drop the "sensor" and "EW" part because for the purpose of this discussion they are both completely irrelevant unless you can somehow demonstrate that the 055's sensor and EW power requirements are in the neighborhood of 67% higher than the Flight III, and we both know you can't do this, so....

As for the HPM, this pie-in-the-sky weapon is about as much justification for "20MW" (another total conjecture) as "Martians live under the earth because we know that some of them are mind-controlling us". One total conjecture being used to justify another total conjecture is not much of anything in the end.

What are you talking about Willis? Flight III still in power point status. 055 basically is the CG(X) that the USN was supposed to do but they chose not to
