Just curious if there are supposed to be black flak clouds when you fire the 40 MM AA shells in TMO 1.9? I can hear them explode but never see black puffs...never fired them at a plane yet, only fired a few rounds off in air for testing reasons.

I don't think so. The HE rounds explode on contact. In reality, the average subs were too small to carry all the proximity fuse fire control radar systems. I'm not absolutely certain that the 5" Flak shells are historically accurate either, unless they found a way to reduce the overall size of the radar units later in the war (haven't gotton that far in my book yet).

Be aware there were several fuzing options, only one of which depended on having a fire control system involved. Contact fuze...self explanatory.

The timed fuze is the one that required a fire control system to calculate travel time and set the fuze.

The radio proximity AA fuze's were entirely self contained and not dependent on a ships fire control for anything other than (hopefully) being pointed in the right direction when fired.

In FoTRS I see mucho AA puffs from the 40's and they are very deadly, especially if you can get a double set of them. http://forums.ubi.com/images/smilies/icon_twisted.gif

Here are a couple of screen shots I sent to Ducimus while he was beta testing the 40mm AA

I am working on a 40mm training mission that may help. I'll keep you posted.

Here's a screen shot.

OK, uploaded the mission over at SUBSIM.

The radio proximity AA fuze's were entirely self contained and not dependent on a ships fire control for anything other than (hopefully) being pointed in the right direction when fired. Ahhhh yes, you're right Pacific_Ace. I just found the story about the developement of the proximity fuse in my book. Quite an ingenius design if I may say so, too. It had a self contained battery that was activated upon firing of the shell. The battery life was approximately 2 minutes, or, just long enough for the shell to reach it's target. Since, the force of the shell being fired would break a tiny glass ampule of acid (inside the battery), the battery itself had an almost indefinite shelf life. A tiny electronic vacuum tube, in the fuse, would serve as a, sort of, mini transmitter. There were two holes bored through the shell where two wires were inserted, serving as a dipole antenna. The shell wasn't so much on a timer as much as it actually sensed it's distance from the target.
And, yes, ( http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif) aim was still of the utmost importance.
It turns out that these shell were used more in the Pacific than any other theater, mainly due to secrecy fears of an unexploded shell falling into enemy hands. It seems that the secrecy over these shells was almost fanatical and, the great ocean expanses of the Pacific alleviated many sleepless nights for all pillows concerned. Still, they did manage to make their way into the ETO as anti-personnel artillery shells (air burst).
The first time they were actually test fired (according to my book) two R.C. drones were shot down with 5" shells but, when the ship's captain gleefully called for another round of practice, his joy turned to anger upon learning there "were no more drones available". They ever needed to produce more than two because none had ever been shot down before. http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif The fuses were then put into immediate production and deployed to the Pacific.
It's obviously much more detailed but, that's the short version. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Bubble Im using FoTRS and have a 40 and there are no explosion puffs.

There's a bug where if you man the gun yourself, you won't see the explosion puffs. If you let the AI gunners do it, you'll see the puffs most of the time.

Thanks Ducimus.So have you racked up any tonnage yet? Noticed you said you were going to acutally play for a while.

Started working on a patch addressing minor issues after a test patrol i just ran. Will start a new career game soon.
