stefaanadriansens Posted August 5, 2014 Share Posted August 5, 2014 i tested the lethal fragmentation of the mk84 in dcs , its 350feet . the second try on same spot it disabled the infantri in a radius of 600 , while the first mk84 damaged the infantri abaut 5 percent , the ones that are on 580 feet radius. the real mk84 lethal fragmentation has a 1200 feet radius. :pilotfly: i7-920, 12 GB DDR3 1600, Gigabyte x58 ud3r, Gigabyte GTX 970 OC, 2x500GB SSD+1x250ssd, TrackIR 5 clip, screen 42 inches, and 21 inches, Thrustmaster Warthog throttle and stick,t500rs,th8 shifter, Saitek Pro throttle, x controller, G11 keys Link to comment Share on other sites More sharing options...
ericoh Posted August 5, 2014 Share Posted August 5, 2014 I doubt the 1200 feet radius is a 100% kill. With so much variables? How much tests did you do? Link to comment Share on other sites More sharing options...
Scrim Posted August 5, 2014 Share Posted August 5, 2014 Honestly, a MK84 is a very large bomb. With the amount of explosives and shrapnel caused by it, I wouldn't really doubt a 1200 feet kill radius. Though of course, those things tend to be calculated with ideal circumstances, i.e. nose fuze against infantry in the open in flat terrain that doesn't have any chances of the bomb burying itself before detonating.

Flagrum Posted August 5, 2014 Share Posted August 5, 2014 Imo there are two things to consider: 1. The Mk-80 series GPBs are not really fragmentation bombs. They certainly produce some good amount of shrapnells, but the main destructive force is the blast effect. I admit, I have no hard data at hand, but I doubt that even a Mk-84 will kill everything within 400 meters ... Probably the "danger area" is 400 meters in diameter where you have a certain risk of being lethaly hit by a shrapnell ... 2. In DCS, shrapnell damage is not modelled. *sad panda.gif* Link to comment Share on other sites More sharing options...

How much tests did you do? tried all fuze settings learned olso abaut the fuzes , the only thing wat is modeled is the noze or and tail , with nose fuze the bomb goes halfway in then explodes. the dsu 33 should make it explode before impact with a ecm jammer or someting. in al testst i did the second mk84 does the 600 feet radius job. for infantri , it should be with the first one. :pilotfly: i7-920, 12 GB DDR3 1600, Gigabyte x58 ud3r, Gigabyte GTX 970 OC, 2x500GB SSD+1x250ssd, TrackIR 5 clip, screen 42 inches, and 21 inches, Thrustmaster Warthog throttle and stick,t500rs,th8 shifter, Saitek Pro throttle, x controller, G11 keys Link to comment Share on other sites More sharing options...

stefaanadriansens Posted August 5, 2014 Author Share Posted August 5, 2014 cordinates of the test is 41 51 08 041 48 19 its near the smaller airfield near wp1. hot on ramp . the zu23 is the center of the field , if you wipe out the 600 feet radius you wil get a text in the upper right corner olso for the 1200 feet.gp84test.miz :pilotfly: i7-920, 12 GB DDR3 1600, Gigabyte x58 ud3r, Gigabyte GTX 970 OC, 2x500GB SSD+1x250ssd, TrackIR 5 clip, screen 42 inches, and 21 inches, Thrustmaster Warthog throttle and stick,t500rs,th8 shifter, Saitek Pro throttle, x controller, G11 keys Link to comment Share on other sites More sharing options...
B25Mitch Posted August 14, 2014 Share Posted August 14, 2014 The following chart can be used to determine the effects of blast overpressure on a human subject for a given weight in TNT. While the design of the bomb can accentuate overpressure effects to a degree, it is probably safe to assume that the bomb would not be more effective than its total mass in TNT. source:http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA286212 Note that this completely ignores the effects of shrapnel. The chart indicates a probable kill line about 30m (100ft) from a 1000kg blast. Beyond this range shrapnel is the only significant factor, which is based on probability with an inverse-square falloff. source: http://www.globalsecurity.org/military/library/policy/usmc/mcwp/3-23-1/appf.pdf This chart indicates a Mk84 10% PI at 225m (note that the unguided Mk84 figure is inflated to 325m to account for risk of aiming error). It is therefore likely that a Mk84 may be expected to reliably kill unprotected infantry at 100-200m range. 'Soft' vehicles would be only slightly more resilient than infantry. Assume a 50% PI of 100m. Armoured vehicles, however, would probably need to be within the overpressure zone (<30m) to be disabled. source: created by B25Mitch Link to comment Share on other sites More sharing options...
NRG-Vampire Posted September 4, 2014 Share Posted September 4, 2014 the last chart is absolutely wrong imho hard to believe that the damage (PI) of the mk-84 is the same as the mk-82 (especially it those are LGBs), while the mk-84 got 5 times larger/heavier filling of tnt than the mk-82 zuni vs hyrda rockets is the same: ridiculous Link to comment Share on other sites More sharing options...

Possibly the shrapnel would be propelled farther, though, but would that increase the PI (Probability of Injury, I assume?). Mk-84 will have a larger blast-kill radius, though. 2nd French Fighter Squadron Link to comment Share on other sites More sharing options...
mvsgas Posted September 5, 2014 Share Posted September 5, 2014 B25Mitch, Thanks, great answer. stefaanadriansens, I would not use wiki as a source of information. Try looking in .mil or .gov sites. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true.. Link to comment Share on other sites More sharing options...
NRG-Vampire Posted September 8, 2014 Share Posted September 8, 2014 (edited) ...greatly affects the frag pattern... more than strange: but then why got the mk-84ld and 84hd the same pi ? :huh: Edited September 8, 2014 by NRG-Vampire Link to comment Share on other sites More sharing options...
WildBillKelsoe Posted September 8, 2014 Share Posted September 8, 2014 the real problem is vertical shrapnel. I read somewhere that the 82's shrapnel could reach 2500 feet. I wonder what A-10 pilots punch in to stave off this stuff. I'm gonna throw a number (5000, double). With 84's, probably 10,000 feet (quadruple) AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow. Link to comment Share on other sites More sharing options...

mvsgas Posted September 9, 2014 Share Posted September 9, 2014 They tail or nose kit should have little effect on the blast. The Fuses ( tail or nose), specifically their setting will have their biggest effect. Additionally the target material will affect the blast, if a bomb fuse is set to .5 mili sec and it hits sand or soft dirt, it will have a different blast that if it would hit a building and blow within.
