This report is interesting, it looks like the chinese submarine force is testing the capability of the USN again. Wonder what sub class is the chinese using.

I highly doubt that the hydrophones in the towed array failed to detect a shadowing submarine from such a close distance. But of course we can not know for sure what happened."According to the CNN report, the US destroyer seems to have failed to detect the sub, while the sub set its distance from the US ship based on the assumption it wasn't carrying sonar arrays. It's highly possible that's the reason for the incident," Yin said
Why does the USN still use an "array"? Now that they have other technology to detect submarines. Such as Satellites (that's how they discovered the underground sub base)?Interesting Chinese viewpoint in the China Daily published also on June 15, 2009.
Sub, sonar collision 'inadvertent'
It seems the sub did not expect the USN destroyer to tow a sonar array. Maybe it could have moved away or dived lower? In any case it was most likely not discovered before it was hit. The sub took a position in the South China Sea from where it could observe the joint naval exercise involving 6 ASEAN nations and the USN, according to the China Daily article. Interestingly the AFP report and CNN did not report the participation of the USN destroyer in a multi-national navy exercise. For China such an exercise is obviously very important to observe.
Ah, interesting. So what technology can replace the SURTASS which got it's latest updates in the last years?Why does the USN still use an "array"? Now that they have other technology to detect submarines. Such as Satellites (that's how they discovered the underground sub base)?
Look up the link. Given the great lenght of the cable and all the technology on the rear and the communication lines it must be rather strong and thus it is rather heavy.how much mass do towed array sonar have? what is their relative size?
since the sub was likely trailing the ship, relative speed should have been pretty close ... so how much damage could possibly have been done from such an impact?

My personal feeling is, the new USAF constellation of satellites Obama gave the green light to , that they are going to put up in the next couple of years, will better detect subs then the current "array" they use to detect subs today. Just a thought, I could be wrong.
The question here is: How? Perhaps you should go first to the thread about ASW where there is a great amount of links and information about the specific topic.My personal feeling is, the new USAF constellation of satellites Obama gave the green light to , that they are going to put up in the next couple of years, will better detect subs then the current "array" they use to detect subs today.

I don't think you know what the McCain was towing.Why does the USN still use an "array"? Now that they have other technology to detect submarines. Such as Satellites (that's how they discovered the underground sub base)?
I don't think you know what the McCain was towing.
The system is question is called a TACtical Towed Array Sonar (TACTAS), it is a series of hydrophones towed behind ship, it is a very good system but it limits the maneuverability of the ship, and it is expensive.
TACTAS is probably the best tool a ship like a Flight I Burke has to track submarines since it can be lowered below the temperature layers.
AN/SQR-19 Tactical Towed Array SONAR (TACTAS)
How exactly will satellites hunt for submerged submarines?
i think a tow sonar can have cable length of dozen miles so i won't say its really close. also i read somewhere that it was the US destroyer shadowing the sub, not sure which way is true. but this is simply a accident, no sub commander in right mind will intentional hit the sonar and risk tangle in it.This may sound weard but why would a chinees sub position itself so close to a destroyer in the first place?
This could have a provocation effect.
IMHO both china and the us are fully aware of what systems they use so its very likely that the chinese sub did know exactly what it was doing otherwise the would shadow the exercise from a safe distance without the risk of being detected... and so on and so on......
I do not know or a us destroyer could detect a diesel running on electrics but iam pretty sure that if the chinese sub was running in silent mode that it would have known that the destroyer was directly near them.
So they also would have known that the destroyer was checking the waters for subs and other non us contacts.
At least thats what i think....
Agreed LIDAR is not the topic here....i just asked or that LIDAR is the system that AegisFCI think you should first read up how LIDAR works. It helps to understand the intrinsic issues and the specific ones if used by a satellite are also rather plain.
But this should be discussed in the ASW thread, and not in here.
P.S: It could have been a simple accident caused by an decision error by the commander of that boat. It is not the first time something like that happened.
Not true. there are already solutions being mapped to replace towed arrays in some areas,It will never replace the towed array - the capabilities and spectrums are too different .
On interpretation and distinction. Agree with the principle per seStill I think that the right spirit was there, but it is no the first time I and gf seem to differ on it's interpretation.
