Question radar detection TMO

[Armistead]

Can't remember, but anyone know the correct distance that JP radar can pick up your sub with TMO1.9.

Chased the large JP TF headed to the battle of Philippines Sea for two days. I sunk one Yamato and had the other one DITW, but out of torps.
I sat beside it why JP planes would drop bombs on me, but hit it instead..yea, I wanted it....course when it started smoking, I had to hall tail and can't be beside it when it blows.

I sat there a few days hoping some US planes would show up, but instead came the JP TF back. It was over 12NM away and I was decks awash and picked up radar detection. Before I know it several DD"s are headed my way fast. I try to haul tail to hide under the Y dead in the water, but they drove me down. I've never had DD's hunt me this bad. I went to 700ft, running silent and they never relented and finally got sunk....I wasn't using the cam, but still....

Anyway, had a save point and gonna give it another go round, just not sure why all those DD's came from that far away with me decks awash, unless the Y sitting there made them react.

Based on my exp with IJN radar in TMO 19, the standard escorts for convoys with radar typically pick you up at somewhere between 5 and 6 miles.

Large warships like Yamato, CV, CV etc have radars with longer ranges.

Successfully did a night surfac e attack on a large convoy in IJN with 6 escorts, one of which had radar.I attacked from the opposite side of the radar equipped escort and stayed about 5.5 miles away from him since i was on far side of convoy, he never picked me up, was able to close to 3500 yards on column of merchants and attack.Got away, his radar never picked me up.

Have tried this on large warships like BB's with radar, they got me at 11 miles.

Offhand i dont remember what radar capital warships are using. But i'll probably re examine JP radar and readjust it again. I have one of my evil ideas where radar is concerned, and if it works, ill be forced to re examine ALL radars.

Well, this is by far the best battle I've been in, so playing it over. I should've just took my one Yamato and left, but hated leaving leaving the other dead on the water. Not sure if I can sink both.

The first attack was funny. I blasted one Y and it was still limping off. The next Y came over me and got in the way of me shooting the other one. I sent my sterns at it shooting at it's butt and the second Y turned in and took all the hits. I was getting mad, everytime I tried to hit the one running the other one would zag and take the hits, so I finally sunk it.

I would like to know the crew settings for the JP's on this one. The TF is spread out over 20NMs and I get inside nicely. Why waiting at scope depth, DD's just come on over from 4-5000 yards away and start pinging, so dodge em until I can shoot....

I assume the capital ships direct the dd's to you with radar. They get close, but as long as you turn and run, they always head back to the group.

Capital ships have better visuals. I won't give specifics (cause it might ruin the fun), but not all ships see the same distances. Generally speaking, on the low end of the visual totem pole is the merchant. Going up the totem pole you'll find the tin can, then the capital warship, and finally the airplane. So it is possible for a capital warship to see you and then alert the nearby tin cans. Offhand, i think capital warships can see about 3KM or so farther then a tin can.

Duc, maybe you'll come back, so won't start another thread. Pretty much figured out leaving your scope up long gets you in trouble, but how about how far extending it.

I use the del/insert keys with my night scope, in calm waters I barely break water, instead of sending it up all the way. Doe's it really matter?
It doe's seem to make a difference, and obvious helps with time on the scope to where you just barely keep it under the surface instead of retracting all the way.

I played with it this mission and all the way up same distance the Y spotted it, barely breaking water, didn't, max time up 5 secs...course didn't matter, 800 yards perfect shot, still the other dang Y got in the way again taking torps.

Well, one Y down, other has 3 hits and going away, think I'll save em and go for one of the carriers when they come back....

Oh yea, when I was trying to sink the second Y last time and it was dead on water with me right beside it, jap planes hit it with bombs several times trying to hit me....do they do damage, well, it did, but never sunk and I bet I had 10 torps in it.

Anyone know the safe blast radius range of being away from the Y when it goes up. At 500 yards, I did get mild damage when it blew at scope depth.

I do not think this is true.
There were two types of radars.
Type 21 :
One source indicates only 1 set of this type built, but same source indicates it was installed on numerous ships. Type 21 first fitted to BB Ise in April 1942, Taiyo, Chuyo and Unyo in January 1943, others prior to August 1943. At least 30-40 sets built and used operationally.
Type 22 :
Fitted to Kazegumo and Makigumo in March 1942, Hamakaze in June 1942, Akigumo and Yugumo in July 1942, Kongo, Haruna and Hyuga in October 1942, Katori, Kashima and Kashii in June 43,Yamato and Musashi in October 1943, other destroyers prior to September 1944. In wide use by mid-to late 1944. Type 22 radar while not designed for gunnery control provided moderately accurate data for this purpose.

TMO is faithful to these data, except for:
- BB Yamato : type 22 from July 30, 1943.
- CA Maya : sunk October 25, 1944 but type 22 from November 4, 1944? True is April 9, 1944.
- CA Takao : type 22 from January 4, 1944. True is November 15, 1943.
