offsetting point and shoot training video, 06:36 minutes long
video http://files.filefront.com/13205735
mission folder http://files.filefront.com/13205743
i got an email from a member, his name is urge, he was interested in using torpedo offsets, and asked me if i could give him a print out of the chart in the cic mod of offset angles, because he cant use the mod.
well, that chart only goes out to 10° either to port or starboard, and the offset angle dial in sh4 goes out to 20°, port or starboard. so i thought i would make a small training video using torpedo offsets with
the point and shoot technique, and see what happens. i made a mission, two t-3 tankers, range 2000 yds plus, moving in column, 600 yards apart, making 12 knots, course 270 r to submarine, closing.
i applied the largest offset angle we could put on the torpedo, which was 20°, and to starboard. now this is a very large offset, and there was a good chance that the torpedo would miss the target, but i applied it anyway,
just to see if the target could be hit . i chose the trailing t-3 tanker, applied 20°s offset to starboard, depth 25 ft, using mk-14 torpedo, speed 31 knots, contact fuse.
now, with a target speed of 12 kts, and a torpedo speed of 31 kts, offset 20°S, you have to shoot the target when the target is on bearing 38° starboard. and since that bearing was pretty wide, i might be able to get another shot
off on the leading target, using a fast mk-14 at 46 kts. so i set a second torpedo, same depth, speed 46 kts, for a 0° offset, which meant i would have to fire when the lead t-3 was on bearing 15°,
tale had made a vid, of attacking two targets at once, nothing wrong with the way he did it, because i was doing that in sh2, but never carried it over to sh3 or 4, the point and shoot method had become my primary shooting method by sh3.
the one problem with tales demo is of course determining the targets range, that is, at least for me it is. the point and shoot method disregards range as a factor in targetting, so not only is this video a demonstration of appling offset angles, its also demonstrates that the point and shoot technique is
enhanced using offsets, and the kill zone is magnified, targets can be engaged on multiple bearings now. i chose the most difficult offset i could, if the torpedo could hit at 20°offset, then it certainly will hit with smaller offsets.
for 12 kt target speed, offsets and firing bearings would be as follows below, the mission is also in the folder of the training, jgme ready, and if you want to, you can load up the mission, and fire using any one of the offsets and bearings
below, and test drive offsets.
at some point, i want to make offset charts of all speeds ive seen in sh4, like 1 to 20 kts, for just one torpedo, the mk-14, and get them into the cic mod, but i dont know when i will get it out, so in the meantime, if this offsetting method interests you, you can make your
own offset charts using that great torpedo solution calculator by dave sandberg, intercalc.
hope this answers some of the questions you might have about offset angles urge,
good luck
