target speed: the eighty-ten method

[greyrider]

target speed, the eighty_ten method
in this tread im going to be introducing to all of you a technique
from the TFCM, and from the realm of imaginative tactics, that which is characterized by
or bearing evidence of imagination.
so if you want to advance your target speed determinations, to an advance level, your probably
going to have to pass threw this post, because no one has done this before, no one has shown this before, and the beauty is
it works great.
"
about a year and a half ago, i opened a tread called: "target speed, seaching for the magic bullet".
and in that thread i talked about a particular angular setup between a target and a submarine, and that if
this angular setup could be maintained, the AOB becomes predictable, and it didnt depend on seeing the target,
in fact the target could be at the maximum listening range of the hydrophones.
so with a closing target being held at a constant bearing, with a known AOB, the targets speed can be determined by using the
submarines speed.
the only tools i used on the submarine to determine target speed is:
submarine hydrophones (just listening and keeping target on bearing)
submarine knotmeter ( adjusting sub speed to keep target at constand bearing)
submarine timepiece (not really needed if target is held constant, but TFCM likes to time it for 2 to three minutes)
combat information mod for TM 2 (has the data to rate a targets speed versus sub speed)
and math formula: St= So*sin LA / sin AOB

where:
ST = target speed
LA = lead angle
AOB= aob of the target

whats not used are maps, plots, radar, sonar pings or ship length.
altho i have a movie to show you, its about an hour and one half long, i cant seem to find a site
to upload the movie to, filefront only accepts vids that are less than 2gb. the movie has 15 parts, each part has about has almost 4 gb,
so i cant even upload it in parts.
this movie shows the submarine holding a closing target constant on an 80 degree bearing,
with a ten degree aob, the submarines speed is 2 knots, so at the bearing and aob, the targets speed is 11 knots.
this speed was determined while the target was over 19nm away, and it took the sub almost 1 1/2 hours to close on it,it was hit with
all three torpedoes fired at it.
what i can do is give you the mission to practice with, i can give you the combat information mod for TM.
the combat info mod has two new charts, one has the data for the 8010 method, and the other is a chart for torpedo offsets, that is,
taking out two or three targets simultaniously, but i really need to make a handbook for the mod first, which explains how to use the charts and graphs.
so ill try to get that up later on, right now this is all im going to say about it.
