Attacking Two Ships at Once

[Laconic]

Attacking two targets in a TF simultaneously, one using the TDC and the other using the Dick O'Kane method. Landed nine of ten torpedoes, and sank a heavy cruiser and a battleship (Guadalcanal TF in RSRD), all in glorious HD!

I just watched that. Good job, and some fancy shooting there mister! :up: I won't lie and say it doesn't put a grin on my face seeing folks use TMO. :O: I do have a question though, and it's not meant as any sort of criticism, but more of ah, "Did i do something wrong?" kind of question.

The night periscope, is there any reason you didn't use it? Is it not working properly?

[Laconic]

I'm under the (perhaps mistaken) impression that it doesn't ascend as high as the attack scope. I do like the night scope, but I wanted to stay as low as possible, so I used the attack scope. Am I incorrect?

[magic452]

Nice shooting and very nice video. :yeah: :yeah: four thumbs up.

I use the night scope all the time and haven't had any problem but I seldom shoot from inside a TF.

By the way did you get away?

Yeah, clean getaway, the DD's never even made contact. I always sneak out the direction the TF came from...I figure that if there's prop noise from all of the ships above me, I'm that much harder to hear. By the time the DD's can get in position to look for me, I'm already squared away deep. Later in the war, the better active sonar on escorts can make this sort of attack risky.

The night scope not extending as high as the attack scope only appears on the early war conning towers of the Porpoise, salmon, and sargo. Once they get the fairwater cut down it's not an issue. I'd have changed this, but from what ive heard the periscope heights are historically correct. If i have that wrong, id happily change them.

Mmm, very satisfying.

Just one wee thing: I've long understood that a sub cannot hover, except, rarely, float on top of a denser thermal layer. To control its depth a sub must have way on.

Like the combination punch and the way you set up the knobs and dials beforehand.

I've got no idea what the historical limitations were...I'm a history buff, but I'm no historian. I just seem to remember that the night scope only went up so high in the S-Boat (http://img.photobucket.com/albums/v167/Laconic/S-Boat.jpg) I started the war in, so I assumed that they were all like that. This is a Gato, so they're probably the same height and I'd just never noticed.

Didn't know that. Floating in one point in space may not be realistic, then, but it makes attacks like this so much more fun!

Like the combination punch and the way you set up the knobs and dials beforehand.It can be done, if you have the time. WWII or modern sub doesn't matter you can do it on both. You just have to keep adjusting your trim as the boat slows to All Stop. You should be able to get a perfect or near-perfect trim this way.

[magic452]

Zero knots submerged may or may not be possible in real life but the ability to go back 1 knot is not in the game, so 0 kn. is justified in my book. It's the only way you can keep station without going back 3 kn. which is not a option if your in close.

hello! tanks for answer abour XO in other thread!

about your video.

How u estimated course, speed, gaps bewtween ships and etc of each ship in convoy group and even made drawings on Map for every each of it with course and position etc?
was it radar?
i still dont have radar on my SS and dont know how to use it :cry:

Im nOOb, i play 1.4 with 92 realism, i sink alot of ships, but thats not much skill but i guess more stupid bravery and "dare" what i do :dead:


All i understood from manauals was Sobers fantastic explained ones about TDC and one with using Sonar for speed and course estimations

P.S> watched tutorial Robins about chart tools, still cant get idea of compass or what is it then u press "help tools" its 360 degrees upside-down compass sowing 0 at south,
I mean, if my map top always showing North, like any other map, whay tools shows coursw 0 at South? If target course is SSE it will show 300smth istead of 140smth targets course!!

dont get it

[magic452]

If you have a target north of you and it's heading south, if you plot it's course on the map starting with the target and drawing a line south the tool help compass rose will show you it's course where the line intersects the rose.
Ex. ship heading south will show a course of 180° when you plot the line.

Knowing the targets true course is helpful in planing an intercept or in some shooting methods.

gonna try it! thx!
what else its usefull for??

To estimate course you have to watch them over a period of time. Pick a ship (out of the convoy) and mark its location. Then watch it and mark its location again and again over a period of time; the more marks you have, the more accurate your course estimation will be. With the ruler, draw a line connecting the marks as close as you can and read the bearing on the side of the compass closest to where the line started; that's their approximate course. Then you draw a long line from the target on that course and see how closely they follow it and adjust it if you need to. That's how you get their course.

For their speed, follow this:
Mark a ship's location
Wait 3 minutes (for Imperial, in yards) OR 3 minutes and 15 seconds (for Metric, in meters)
Mark the ship's location again
Measure the distance with the ruler
Divide the distance they traveled by 100

As long as the ship hasn't changed speed or course, that will give you their speed estimation. Before the video started, I did that...I marked their location, waited three minutes, marked their location again, and measured. They traveled 1500 yards. 1500 divided by 100 is 15, so I knew they were traveling about 15 knots.

I spotted that Task Force long before I started the video. I watched it and shadowed it for a long time trying to judge its course and speed. I didn't start the video until I was satisfied with the course and speed and until I was in attack position.

[WitoldGritz]

thx,
Dont know about you, but i play high realism, i have no moving dots on map, or nothing like i saw on your tutorial
how bearing course dots can help me without estimated range?
and i cant ping warship every few minutes, i guess i can get detected. if its marchant then yes.

If you're playing without any map contacts at all and aren't in a situation where you can ping your target, you're either going to have to estimate the range based on radar readings on the A-scope (I also believe there's a mod out there that will let the radar report ranges) or you're going to have to close to visual range and manually get range reports from the stadimeter. Just check the bearing of the target on your radar/periscope, note its estimated distance (either on the A-scope or on the TDC after getting a stadimeter reading), go to your map, and put a mark at the correct range on the correct bearing. There may be a better way of doing things, but this is how I would do it.

If you use this method, you're going to have to make a lot of marks before you can get an accurate course estimation. If you're chasing a task force like I was in the video, you'd probably end up sitting well off of its course while making your readings, letting it pass you by, then doing an end-around to get in front of it again and make your attack.

[WitoldGritz]

Yes i know its complicated and i like it.
well thx to you very much you very helpfull!!

its not even 2nd week of my carear its end of 1941 and i have no radar btw what ods fixes those problemes with radar, reports etc?
and i have some issues, chech Borneo thread in here.

what mod makes "ship identification" task of XO and its fast and realiable? I have team, of officers, helmsman and etc, its strange if i do all job "alone"

There's no real problems with the radar. You don't have it yet because it is not available in 1941. It won't become available until mid-1942. As for the mod that will have the radar report range, I'm not sure, I just remember seeing it.

The ship identification is part of Trigger Maru Overhauled. TMO makes sweeping changes to the entire gameplay experience. You can find it here:

They have a word for captain's like you. It is "ACE." You are ready to instruct at the War College.

Pshaw. I knew nothing when I picked up this game two years ago, just careful study and practice. It took me about five takes to get the video like I wanted it...some of the bad takes were technical issues, but on one at least I forgot to set the speed on the TDC when I activated it for the battleship, and sent my torpedoes harmlessly astern of it...NARF.
