054/A FFG Thread II

[Blitzo]

I am pretty sure that it is and I doubt you are going to make a new radar system just for the 054A/P. The R/D to develop something that will only be used for a few units of export would be costly and inefficient, not to mention it would take time to develop and vet for use.

It is also pretty clear that the radar is small, a lot more wide than it is tall. That fits the SR2410C, and even if it isn't by very low chance, its operating characteristics would still be similar.

As I said, I'm okay operating under the assumption it is SR2410C for the purposes of discussion

What do you mean "technological eras"? Regardless of technological era a bigger array is still a bigger array, and the array's geometry matters for its ability to receive and measure. A bigger array will no doubt capture more photons for a stronger signal. Not only that, with the bigger array, the differences in the photons as they strike various areas of the array becomes more pronounced, in their time of arrival, the frequency as of arrival, the amplitude as of arrival, and it is these comparisons between all these signals that produce the data that matters. This is oversimplifying for the sake of a post but its the gist of it.

I'm not sure if your question is serious. The technology that is inside a radar like Smart S Mk2 vs something like SPS-48E is quite different. They are literally decades apart.

Range and elevation performance isn't everything in comparing different radars.
Heck, the array everything either.

IMO the radar you see on the 054A/P right now, isn't optimized for dealing with high altitude threats like bombers and drones. If the PLAN is willing to accept that as a compromise its their call. But looking at why the Type 382 was selected for the Type 054A, replacing the 2D horizontal scan only Type 360S on the Type 054, suggests air defense against high altitude threats is part of what they are looking for back when these things were conceived.

Smart-S itself getting replaced by NS50, NS100 or NS200 in frigate sized vessels, all squarish arrays.

They can take the SR2410C and reshape the array with a more square proportion, increasing the number of elements in the Y axis. But it would also be the same as taking that dual sided radar and making it a single sided one.

"Isn't optimized" is the key phrase here.

As I wrote in my previous post:
IF the new twin side AESA seen on 892 is capable of being fitted onto 054As, then obviously that would be ideal.
But I think that might be aiming a little bit high and overambitious. I am not sure if 054As will have the SWAP-C to accommodate a radar of that size.
In that event, I think the most likely radar for the new batch of 054As may be a domestic variant of SR2410C -- and I think that would be perfectly adequate for 054A.


Let me put the question to you another way -- if the 054A is unable to fit the new twin side AESA, and if these restart 054As are only capable of accommodating the same Type 382 we all know and level, versus, SR2410C, which of those two do you think would be better for the 054A?

SPS-48E still has a range of nearly 500 kilometers. This despite it is very old, going back to the sixties. It is Pre-AEGIS before there was AEGIS.

It is meant to scan, detect and track large volumes of the atmosphere from high to low. There is a very good reason why the USN has kept this radar for so long, and its still a vital part of the Nimitz class.

I do not think the SR2410C and the SMART-S is optimized for high volume high elevation search as having a taller, more squared array would be.

If the SR2410C comes for PLAN and 054A use, they would and should redo it, doubling the number of elements for a more square array.

Won't a new Frigate arrive?

And what is the hull on the right?

I think its the other half of the ship.

They placed the aft sections of ships 3 and 4 in a row to the left, then the fore sections of the two ships to the right.
