I dont know why in the world anyone would think that a hydryphone head is an air search radar.Unless of course you where unawre that the SD radar does not rotate and can be raised so that it can extend above the water when the sub is at periscope deapth.For some reason the head only spins on the surface and not underwater but that is no air search radar.Though it would be obvious to me that that is no radar it would be useless at such a postion.The SD radar is on top 3rd periascope(which no longer is used for optics the one most to the rear or the boat.)The SD radar does not sweep anyway.You are thinking you know Platapus and I are knowing we know.

Like Platpus said those are two diffrent type of device and they can both ping if the need arises they could also be retcacted inside the boat when not in use something that you cant do in SH4.All though that is not the olny type of sonar systems that where used there was also JT and WFA.The JT is pretty much the same as the JP head t was just larger and better with WFA there was also a super sonic transducer topside.Some WCA had a topside transducer but not all did.

Like Platpus said beter to read the data else where from an online source or book SH4 does not do alot of things correctly.It is not a very good source of information.Well Sh4 pretty much says nothing at all about most of the equipment in it.
