Active Sonar

GunnersMate · 09-08-08, 08:40 PM

I know this sound kind of dumb

but can merchies hear our active?

banjo · 09-08-08, 09:04 PM

No, but it says somewhere that DD's can.

They'll pick up on depth sounding as well (also active sonar).

Think historically some merchants were fitted with hydrophones late in the war, which would allow them to pick up on it as well. Don't think it's modeled in stock, but some mods might. :hmm:

I assumed they could, then heard they could not (was not modeled in the game). The other night I pinged the heck out of a lead destroyer in a convoy from a mile or so off, and he didn't seem to change his search pattern. (late 1943). I don't know a definitive answer though.

From a mile out? Did you even get a return?

Were they cruising along at 20 some knots?

Ping one for range inside of 1,500 yards sometime. That will get their attention. :rotfl:

I'm pinging a warship right now, so far without consequence. It's not an escort, but it does have an escort 1500 yards ahead and he hasn't picked it up so far either. I am doing widely separated single pings to modulate my speed. Once I close to 1500 yards and match speed I'll give the situation 30 minutes to take 'em off their presumed guard and see what mayhem I can create with my sugar boat and my four remaining Mark 10s.

3 escorts and a strange warship from RSRD. This could be VERY interesting :hmm:.... or suicidal

Wait a minute... you have active sonar on a sugar boat?

Is that something you shouldn't have?? Like radar on the s-boat??

Honestly I dont know. I just thought that by the time asdic was in 'common' use the S boats were more or less phased out.

Rockin Robbins · 09-10-08, 02:38 PM

Actually I hadn't thought that it was unusual. But come to think of it, I have a full TDC too. This is my first RFB cruise, December 1941. I'm not the expert there on what equipment my boat should have. If it turns out that I shouldn't have it I'm suing the RFB team to get my purchase price back!

LOL get em for twice the price :rotfl: :rotfl:

No seriously I dont know it may be perfectly viable, I was just under the impression that the S boats were at the ass end of the silent service and got the 'goodies' last if at all.

S-27 and S-28 had JK/QC Sonar, which was both passive supersonic and active supersonic sonar. QB (supersonic projector) was in production before the war started, but I think they were steered towards new contruction. I'm not sure about NM sonar (depth fiding) on the S-boats, but the S-boats were used as guniea pigs for testing new equipment, so you'd be surprised what some of them had. JP was passive and a late introduction, coming in after SJ radar.

QB was known to be fitted to a number of S boats, depending on when they were modernized. S-18s started being refitted in late 1942, while S-42s started their refit process early in 1943.

As for TDCs, apparently S boats were fitted out with the older TDC Mk. 1s as they were taken off the fleet boats, so it's not entirely unreasonable to have a TDC on the S boats (though, early in the war, they shouldn't have any sort of TDC).

A number of S boat did receive fathometers, yes.
