thanks guys for the compliments, this was the first time i tried to make a movie, and the first time
i tried point and shoot with the radar, i didnt think i was going to publish that, but since it did work,
i wanted to share that with you, and not keep it to myself, i figured if you could see it, than you would know
it was possible, and you guys would start working with the radar too,
im going to get a microphone, maybe tomorrow, and redo point and shoot with radar, and add voice this time.
i watched that film, and even i learn something from it that i knew but forgot.
the ship that was sunk was at a range of 2000 yds, the one that was missed, may have been 1500 yds, when i shot at the 1500 yd ship,
it was very hard to see that ships pip because of the brightness of the antenna. but the ship that was hit, its pip was easily seen,
which tells me that the radars are better for targets that are at the longer ranges, 2000 plus yds and out.

it also occured to me that the relative movement of ships at close range, 2000 yds and in closer, seem to travel faster threw the firing bearing,
and at longer ranges, the speed of a longer range ship seem to go threw the firing bearing alittle slower, even tho both ships are traveling at the same speed.
so at longer ranges it seems you have the better chance of hitting the target with radar.
even with the hi res radar mod, it is hard to really know when a ship is on the firing bearing, so what i did was i had a 6 inch clear plastic ruler,
i put one end of the ruler over the center of the ppi, which represents the sub, and the other end on bearing 13, so that i had a clear line to judge
when the target was at the firing bearing, i put the ruler right on the monitor screen to do this, that works fine, but i would love to see a mod that could overlay
the 360 bearings lines over the radar screen.
so ill redo the point and shoot video, this time with voice, im also going to try to shoot from a longer range, like maybe 5000 yds, with another convoy.
i am running your radar range mod Nisgeis, that is another great mod, like animated fans and the sliderule mod,, you gave us something that wasnt there before, im grateful for that and your work,
i just hope the devs are watching the modders, and see what there doing, so that they can incorporate the work of the modders, and thier ideas, into the next version of sh,
because these are things that should always be in the subsim

i have posted another silent video of the point and shoot method, by radar. there is no narration, i have tried for three days to make one narrated by me,
but i cant do it,
i guess im microphone shy.
if there is anyone who understands the point and shoot method, and wants to make a narrated video of an attack by radar, your more than welcomed to make one,
dont wait for me, it might never get done. nesgeis, rr, are you up to it?
i have made a mission, to teach the point and shoot radar method, and i have decided that the instuctions for the P+S method, can be radioed in, and following the radio instructions should get anyone interested comfortable
using P+S,R.
i will probably upload that to filefront sometime tomorrow night.

the mission in the film is from my fifth mission in my current campaign, a few days later than the first video i posted.

http://hosted.filefront.com/greyrider/

this one here is an hour long, played in real time, the target was a 22 ship warship task force, composed of at 11 escorts, the rest being capital ships, with fleet oiler and and or repair ship.
4 torpedoes were fired from the bow on bearing 340.5 degrees, and three torpedoes hit the battleship. range at torpedo impact was 2.23 nm, or 4534 yards.
the torpedo firing sequence begins at about the 53rd/54th minute of the film. this attack was conducted purely with radar, but the choice of the target was made with the hydrophones.
speed of the task force was estimated using nisgeis radar range mod, by locking the antenna on one of the contacts, and watching the range readout count down in sequence
before losing contact with that ship, and picking up another one at a different range.
200 yds at 12 seconds gave me 11 kts. bearing to fire was 340.5 degrees, torpedo speed was 31 kts, torpedo depth was 12 feet.

you can compare this attack to one in real life, the uss sealion's sinking of the battleship kongo with two torpedos.
the story is here:
http://www.combinedfleet.com/eclipkong.html

the audio tapes of the sealion of the actual attack conducted by radar here, there are 4 tapes.

tape one:http://www.hnsa.org/sound/sealion/sealionkongo1.htm
tape two:http://www.hnsa.org/sound/sealion/sealionkongo2.htm
tape three:http://www.hnsa.org/sound/sealion/sealionkongo3.htm
tape four:http://www.hnsa.org/sound/sealion/sealionkongo4.htm

theres really no doubt that Captain Eli T. Reich, commanding the sealion, was using the point and shoot technique, on this one.
i kinda like how rr names a tactic after a us captain, so if rr makes a tutorial, and i know he can because he understands the p+s method,
and wants to rename it, i wouldnt mind it being renamed to the Eli T. Reich method.
