052C/052D Class Destroyers

Tam said:

Better to refer to them as three batches, blocks or flights.

052D original

052D - 2nd block
Type 730 replaced with 'Type 1130
Type 346A radar revised, losing the external calibration probe for an internal calibration system.
A pair of ESMs near the Type 366 radar has been changed. Cylindrical oil filt er look to R2D2 look.

052D - 3rd block.
Helicopter deck extended.
Replacing Type 517M VHF radar to what netizens refer as 'Fly Swatter', possibly Type 520 designation.
SATCOM layout has changed with redesign of the top of the hanger.

Thanks! That is very clear for me.

Not yet. It would be easy to spot visually by changing the 730 CIWS to 1130 CIWS, the Type 346A radars would lose their windshield wipers (the field calibration booms for the AESA), and the cylinder shaped ESMs to the R2D2 shaped ones.

A few 052D, namely 120 and 155 are like in between the first and second blocks. They have the first block features but the radar has been upgraded to the boomless variant.

Surprisingly or perhaps not so, most if not all the 052C has all their cylinder shaped ESMs changed to the R2D2 ones, so I guess those things are important enough to do this effort. The earlier 052Ds have not made the change yet. These things remind me of the DWL002 passive radar detection system and the new one remind me of the VERA NG.

Thanks, how many original 052D that still has 730 CIWS ?

For 052D Block 3, is this the radar you're talking about?

I'm not sure if they got the right designation though. Wiki said Type 518 is actually the radar on the original 052, not the 'Fly Swatter'.

The picture obviously does not match the description.

Currently all of the first batch. This does not mean all of the 'short' 052D however.

Of the 13 original length 052D, 8 belongs to the first batch, 5 belongs to the second batch (improved radar, ESM, 1130 CIWS). So 8 still has the 730.

The entry is completely wet.

Sea Eagle refers to the Type 382 radar that is inspired from the Russian 'Top Plate' Fregat MAE radar. This is the radar that you see on top of the 054A, and at the highest mast of the Liaoning and Shandong. It is an S-band not a C-band.

Type 518 is indeed the original radar on the Type 052 and has never been seen since. This is an L-band radar. The Type 052 replaced it with the Type 517M during its refit.

Note that 'Fly Swatter' is what netizens call it. Its not an original NATO code name like Rice Lamp or Rice Hat. This can be Type '520'. This radar should be in the low VHF range given the spacing of the antenna elements, not the UHF range (NATO C-band).

Type 518 should be the radar on top.

Is Type 382 using S-band on both panels?

It is said to be using S-band in one side and C-band in another. Although the exact bands are not clear, the spacing of the wave guides between the two faces are not the same, so one side uses a longer or shorter wavelength than the other.

Russians are having S-band on both arrays.

Top Plate appears to have different spacings and sizes of the wave guides on each face. If both sides are S-band, they are different wavelengths on the S-band spectrum.
