With FFG going slow (under 5kts) it wont cavitate and is VERY quiet. Properly deployed FFG's tail sonar is pretty good. With good handling it's fair even without helos.
Also good trick is to drop OTS buoys. Think of it as towed array which never washes away, just takes 2 minutes to deploy.
To learn about FFG's own noise, drop OTS diffar shallow, circle around it at different speeds and watch how signal changes on buoy display. |
What do you mean with "properly used"?
Because what I did is to check for a layer with a BT: I found a convergence zone at around 2000ft. Ordered all stop so the TA went down to ~2200ft. Was still unable to see the Foxtrot at around 10nm...
And the buoys, what's theyr range? I use DICASS D/S and it seems to be less than 5nm against a non cavitating diesel sub...
Another question: do they have the ability to fire buoys in RL ?
ANd the MAD on the helo, what altitude do you have to fly to have it be efficent? and it's approx range? |
You are unlikely to detect a submerged conventional sub with the TA - it was not designed for that. The SQR-19 was designed to detect nuclear subs in the open ocean, which it does well, particularly in the game. 20 miles in the surface duct is not unusual. To detect a non nuc you can try active sonar, and the helo dipping, and buoy fields if possible, although passive buoy ranges will tend to be terrible. Detection ranges are not going to be long; what you are doing versus a non-nuc is suppressing it and/or avoiding it.
I'm also being led to believe that perhaps your oceanographic knowledge could use a little more robustness (if that's a word), or at least the terminology. What you describe is not a convergence zone, or at least not how a convergence zone works. It sounds maybe like you tried to put your tail in the deep sound channel axis, which isn't necessary or effective. You want to tow it somewhere near the sub's expected depth to exploit a submerged CZ, although again with a non-nuc on battery CZ propagation is unlikely enough that I'd say you'd never see it. Tow in the surface layer to enhance torpedo detection.
And yes surface ships can deploy and process sonobuoys. 5nm with a DICASS buoy is flat out amazing range. Sonobouys are tiny little devices and ranges are extremely limited, which is why you normally need fields (or other arrangements) of them. DW is very generous in that regard.
