This system is not designed to hunt pirates, contrary to what the comments in the CCTV-7 report suggest ...
Look like designed to hunt Sub

I wasn't aware that any of these ships had a towed acoustic decoy system. 054A all have HMS + TAS AFAIK but only some of them have VDS; it's possible all 054A may get refitted with VDS during major overhauls, though. 052D only has HMS + TAS.

From what I currently understand, they operated towed acoustic decoys first, with roots from the BTA-1 system of 956E/956EM, with one the earliest fitted on 054 & 052B before they to moved to the combo of acoustic decoy + the more advanced TASS on 054A and 052C (their port side ports are for towed decoy arrays, while starboard ports are for deploying TASS).

Now here's the issue. I know they recently moved to the a TASS+VDS in 052D and newest 054A batch/flight, but not sure if they dropped or continued to operate an acoustic decoy system in 052D.

In the quarterdeck photo 052D's VDS and TASS is clearly shown and going through which openings, but the one on port side in which should expect for the torpedo decoy, has a square port similar to the starboard port for TASS on 052C, and older iterations of 054A.

Besides VDS, the TASS and TAD ports on the newer 054A hulls are similar to older iterations, so I believe they are configured with a VDS+TASS+TAD setup.

So I'm not 100% sure if 052D has dropped the towed acoustic decoy and added an additional TASS, or has the same VDS + TASS + TAD configuration.

Besides HMS, do you guys believe a VDS +TAS+TAD setup is more capable than a VDS+2 TAS cables? I'm not aware if the latter is even used in other ships.

The LCS's ASW module and Type 45's SSTD system shares the same VDS+TAS+TAD setup in younger 054A hulls. With the LCS's light weight tow described as an acoustic countermeasure if an torpedo is detected, or when the vessel is sub-hunting and uses it active sonar components on its VDS & HMS.

Because 052C's TAD opening is on its port side, and we know 052D's TAS occupy the new one right next to its large VDS port, my bet is 052D's TAD is still there and hasn't changed location from 052C, and when the new 054As adopts this VDS +TAS+TAD transom arrangement.

If 052D is as configured, then a lot more care is needed to assess the transom ports for the ASW suite on new ships like Type 055, if their shapes and design keep changing.

Basic 054A's TAD position, which hasn't changed for those equipped with VDS, and adopted by 052C and should be the same for 052D.

It's a solid guide on the types of towed arrays operated by the PLAN before 052D.

I wonder how effective towed decoys are these days, given that torpedoes should have enough processing power to identify decoys and should be smart enough to reacquire a real target on another attack run.

So are anti-torpedo torpedoes the way forward?
