Interesting. That is true, I believe I did find one at 90 ft on a recent patrol though. However, that is too shallow to hide under lol as they were still ble to track me with ease and put charges super close until I went to 375 ft, but most layers are found somewhere between 150-300 ft.

Yes, I do recall in OM that it became hell to run a patrol in 1943 onwards, mainly due to aircraft. I had to heavily modify the airstrike.cfg and others to stop the absurd number of planes inherent in SH 4, but their skill an ability to detect, hunt made it difficult to survive even with reduced number. I believe once or twice I made it to fall 1944 but always ended up getting killed, by AC or hedgehogs/DC from nasty escorts. I did not mind because it reflected reality of Allied ASW by that point. TMO planes are inherently dangerous, esp early war without radar and in late war, they have a sensor simulating MAD, can detect and depth charge player submarine at 300+ feet, one nailed me at 375, caused serious damage.

yes, i have done the same. otherwise playing is just too tough and no fun at all.


hedgehogs....do not speak to me of hedgehogs. they are the devil's spawn!

lol yes they are evil. I recall a great career in OM, made it from 1939 to October 1944...attacked a convoy. Two US DE stayed behind hunting. Boat was a wreck from DC but no hits from hedgehog. 17 hours under water, surfaced at night, as got underway....aircraft spotted, forced a dive. Well here comes the DE's again joined by two more. Evaded them about 45 minutes but could not shake them. Finally a JCB Class DE came in with hedgehogs and got a hit, hull damage, flooding, then a second one came in, boom, another hedgehog hit, hull collapsed game over. Honestly, prob should have been over after first hedgehog hit. Know of any boats that survived a hedgehog hit?

Japanese never deployed ahead throwing ASW mortars (hedgehog) but were developing them, so on a very limited basis in TMO they now appear in 1945...provide a nasty surprise.

How about in real life, during the war? Are any known to have survived a hedehog hit?

No prob. Well, was wondering if any took a hedgehog hit and made it back to port to tell about it. Possible some survived initial hit and were lost after, en route home etc. The explosive charge on the hedgehogs were not the large, but enough to hole a submarine from what I understand.

If memory is serving Me right... :hmmm: & I think it is... hedgehog explosives, the detonator, was not in what depth it was before going off, the verdampt things were made with a contact fuse. Meaning that with their ability to be fired off well ahead of the charging in destroyer or escort ship so enabled with the devil's spawn things... the charges would sink down at a fast clip...Any making contact with the hull, well... it's be a bad day for the crew.

The explosion from it, would be right there, on the subs hull... very much guaranteeing hull damage & the sub getting holed.
Of course, the verdampt things, did not need to be big, owing to the... knowledge of explosives being advanced, at the time they were intro'ed into the war, that what was used for depth charges, would not work for those devil's spawn things...

"big things come on small packages" expression, comes to mind here. :yep:

M. M.

If there are multiplication then if the fog factor = 0.5 the more fog make AI vision better and the fog factor = 1 make no handicap.

Well.., i don't know how it came to my mind, but this is mistake. Here is simple calculation (for example): fog factor*fog(some value)=handicap. Then more fog (or less) don't influence vision itself without fog factor or fog factor=0. So don't take attention on it.

I meant to respond lol but been busy in life and time on SH 4 has been spent creating new campaign orders...which can be quite time consuming.

Yes...to keep it simple....0 means fog has no effect, number larger than 0 increases handicap. So 1.0 is a pretty strong handicap in the fog, 0.5 is somewhere in between. I have been testing and still deciding on the perfect balance for this setting. As mentioned, settings on the particular visual sensors in the AI Sensors.dat file also come in to play. So fog will handicap a merchant more than it will a escort and a capital ship. This can be used to simulate the superior optics for gunnery a escort or capital ship will have, range finders etc. Then if they have radar which acquires you, they go into "alert" mode and their visual sensors may spot your sub, then they begin to track you visually in the hierarchy of sensors used by the AI.
