1945 patrol....decoys in TMO RSRD

Bubblehead1980 · 01-28-10, 02:23 PM

Playing a career in Feb 1945 with a Tench class, first patrol in Yellow Sea.Afer 6 days in area with nothing, boom, convoy with one large freighter, one small and 3 escorts...PB 103, etorufu escort and type AB coastal defense ship, all with radar so no night surface but with ST radar(periscope radar) on the night scope and the color lense, easier to do scope shots at night so went for it.

Attacked and sank the large freighter with four Mark 18's, two hit the small but one was a dud so it didnt sink.After 6 hours of evasion with about 200 feet of water to hide in,escaped, decoys helped, only one charged came real close, shook the hell out of my boat.Was middle of day by this point.

After a long end around, was ahead at dusk when spotted 4 fishing vessels, guessed i had time for some gun action, so went for battle surface, quickly sank the fishing boats.Night time, moved in on convoy for scope shot with stern tubes.At 2100 yards, was ready to fire when the outside escort started pinging me, adjusted target speed hoping theyd still hit and fired, dropped scope, went ahead flank and headed for the bottom.Fortunately was by now nearly to the Tsushima Strait, had 470 feet under me.At 100 feet, 150 feet and 200 feet I dropped decoys, then went to 1 knot and leveled off at 350 feet .

I could hear the escort roaring in and then counted many splashes, then many loud explosions but could tell they were all above me, decoys worked again.They pounded on the decoys in ideal sonar conditions, flat calm seas, while I snaked away.The two fish missed the target, ah well, do it again.

Now, in real life were decoys that effective? I dont mind them being perfect in the game, just curious.Ive launched them and had them only distract the escorts for small amount of time, but they are great.

No idea! Info is hard to come by on many things associated with US subs. I made them at their current effiency because:

a.) As long as you had to wait for them, i thought they ought to be a significant upgrade.

b.) From previously playing SH3, i found decoys a disappointment most of the time. I decided that combined with the above mentioned point, this dissapointment was to be avoided.

and

c.) probably most importantly, The japanese were quick to claim a kill. They were umm... overconfident. So its entirely plausible, that where Submarine Bubble targets may not have fooled Allied sonar operaters as much, its entirely likely they would have fooled Japanese sonar operators by a fair amount.

you did well, i like it, they work but are not perfect ive had some escorts who are only fooled for a short time, again good job

A must have in Formosa. What's strange is say I have six type A's, if five stay with the decoys, always one will come a searching, pinging and dropping good runs. You hear them speed up, so that means they have contact. Usually if one gets contact, the others in a range will come join, but they don't, they stay with the decoys overall.

I also like to drop them and dive. Not sure how good it works, but in Formosa, say 200 ft of water, if they ping me, I'll drop one and drop down some. If they get ready to make a pass, I'll hit dive and drop another.

Be interesting to know how they guage what depth you are. Even if I have to come up some, I like to radically change depth as they drop, cause most will blow above me. Got to be a point in the game programming that sensors register what depth you're at, if you know it, that would be the time to go deep. I assume it's when they speed up..

Sometimes if I'm deeper, say 400 ft of water and I'm near the bottom, I do the reverse. When they speed up I hit flank and rise and they usually fall under. Sometimes I'll blow the tanks to get a faster rise, lol

works good if it makes sense.

Well I go deep, drop couple decoys on way down at diff depths and stay deep, rather have charges exploding above me, can do more damage when they explode below the sub.

Explain better. Let's say medium depths around 300. You're already deep as you can go and as one starts a run, if he has me as a good contact the charges will drop to 300 ft, so when he speeds up, I assume his depth is figured and locked in to drop to 300 ft. So after he speeds up, I'll head for about 200 ft fast as I can. Usually only do this in calm water and it seems to work well. Course depending on ship, some drop many charges some set to go off at different depths...so regardless I'll stay deeper and flank forward or reverse to miss them. I've actually had better luck staying at one knot in shallow water and hitting flank reverse when they speed up, mostly with the TYPE AD's, cause they double shoot.

What I'm trying to figure out is at what moment do they register your depth for the attack, just not sure.
