Iranian Missiles | News and Discussions

[drmeson]

What is the blast radius of a typical Iranian ballistic missile? For example Khorramshahr? I remember reading that a tomahawk cruise missile had a blast radius of 25 meters. The tomahawk has a payload 450 kg. Khorramshahr has a payload of 1800 kg so a blast radius of 100 meters? Or am I wrong?

That depends upon the warhead's choice, not the missile vehicle itself. One can use a super-dense thermobaric warhead on a relic Rocket to enhance the blast radius. The missile is just a carrier. IRFC-AF has demonstrated using multiple mission-specific warhead types like cluster munitions, MIRV (3x), deep penetrator etc. There are videos for precision strikes.

You can calculate it with this formula (Kinetic energy on impact is not included here)
Translated from German Wiki Article About Explosion Power

Explosive power is a designation for the destructive effect of an explosive. It is often given as TNT equivalent. Correction factors take into account the different explosive power. For example, the energy density of wood is four times that of TNT, but the reaction rate is extremely low.

The higher the pressure differences in the air caused by a blast, the higher the expected damage:

3 mbar: sound pressure level higher than pain threshold of 140 dB.
10 mbar: damage to window panes
35-70 mbar: shattering of window panes
50 mbar: upper limit for reversible damage to living beings
70 mbar: Damage to houses
140 mbar: Collapse of roofs
170 mbar: rupture of eardrums in 1% of exposed persons
200 mbar: Severe damage to steel structures (high-rise buildings)
490 mbar: Overturning of passenger cars
700 mbar: Collapse of residential buildings, rupture of lungs
1400 mbar: Complete destruction
2000 mbar: Death by direct pressure effect in 99 % of the affected persons
The estimation of the range s of a blast with the explosive force M, at which a pressure difference P is still measured, is carried out according to:

where: s = range in m; P = pressure difference in bar; M = TNT mass equivalents in kg.

DONT FORGET: NEWER IRANIAN MISSILES (WARHEADS) HAVE 2x to 4x TNT Equivalent.

10 tons of TNT create a pressure difference of more than 350 mbar in a radius of about 100 m. 1 kg of TNT devastates a radius of about 5 m with a pressure difference of more than 280 mbar. The Little Boy atomic bomb dropped on Hiroshima in 1945 had an explosive force of 13,000 tons of TNT. The largest man-made explosion, caused by the Tsar bomb, had an explosive force of 57 million tons of TNT.

I calculated this one time by myself and Destruction blast radius of different Iranian missiles was between 15m and 30m (all different types with different factors maximum up to 1,6 x TNT because i calculated it years ago.)

Why are we assuming that a BM like Khorramshahr or Sejjil is carrying obsolete TNT? there are multiple more power yielding warhead choices

Do you have any photos or videos from the exercise? This is a huge development that went underreported by the media, I guess.

Most of these pics are actually from great Prophet exercise videos. They literally showed a separating MaRV Stage being loaded on the 2nd stage which due to dimensions gave Mr. Norbert Brugge (and many other experts) the idea that it is Salam-TVC pretty much like Qassed's third stage. An IRBM-ICBM that can go through mAD shields like a knife through butter.

Yes its huge but because of mismanagement of information it went noise-less. We don't care, we are not noisy people.

I mentioned that explosive power of any kind of explosive is calculated in euivalent on TNT. And I calculated here with 1,6 times TNT equivalent. That menas that every single kilogramm of that explosive is comparable with 1,6 kg of TNT.
And these values are realistic with modern explosives. Dont expect 3 or 4 times TNT in absolute mass production. Even if values like 3 or 4 times are common i took pessimistic values wich you can definitly rely on.

If Iran can modify its BM´s to carry at least 7 tonnes of warhead for a usable range of 1500 km, Iran could carry "Father of all bombs" with more than 44.000 kg TNT equivalent with its missiles. That would mean a Destruction radius of 120 meters. Diameter of 240 meter total destruction. If we want to calculate for heavier destruction rates like concrete buildings and 99% mortality rate than Radius is = 90 meters and circle would be180 meter.

OK but know this, some of the solid-state research thermobarics have exceeded airblast yield 2.5x that of TNT. Have they gone to bulk production? nobody knows

I hope so. 2.5 times is very nice. Iran also started massproduction of advanced explosives.(Octogen) In one article I remember i even read a TNT equivalent number but i couldnt remember it. (Somebody maybe have some information?) I remember 10 years ago 1,6 equivalent was a very high standart. Today with Nanotechnology and Advanced Computing & Simulation we have much better output. Of course i really hope that Iran mass produces the 2x or even 4x as a standart.

Here Are some examples of public known non nuclear explosives compared to TNT:

"Relative effectiveness" is the comparision strenght to TNT:

(Kinetic energy on impact is not included here)

What if it is?

 

[Arash1991]

What if it is?

Destruction range will go up.
It depends how missile hit its target.Air blast explosion will produce air blast effect wich is good for destruction range. Direct hitmay produce also some destructive energy. Depends on with what speed missile hit its target.

That's a hard question to answer, but your assumption is probably correct.

The typical HE or themobaric Iranian ballistic missile will probably have a lethal radius of 20m, the shockwave is visible beyond that which can also be lethal but cause small amounts of damage to infrastructure up to 50m (cracking walls, shattering glass, damage to ears, and brain etc..). The damage is not even the explosion as much as it is the kinetic energy that is released that a cruise missile can't match

I don't expect a human to survive 20m from impact unless they have some good cover. With bad cover, the shockwave can be lethal as well at 50m

Khorramshahr with its heavy warhead may not have a large explosion radius, but by virtue of physics the shockwave would be lethal much further than 20m.

You can see the shockwaves illustrated here, go well beyond the borders of the mock facility.

if you google scholar or ScienceDirect articles you might even find some new explosives/warheads that have shown 3-5 times equivalent power of TNT.

Thank you for that Information. Do you have any information about mass productionb capacities of those explosives ?

I have familiarized myself with the topic for the last few days and found the research very interesting. For example, in 2000 the German Howitzer detonated an explosive of a relatively slow explosion speed. The pressure difference is not particularly high, but the pressure difference lasts much longer, which leads to lung tears and injuries occurring much more frequently and intensely.
