Russia’s IRBM attack was done without warheads, it was. WARNING!
Nevertheless it was similar to a FAB250 bomb.
Let’s calculate the Oreshnik's arrival at Yuzhmash:
- The flight speed of the warheads is 3 km/s
- The average diameter of the warhead is 50 cm
- The density of steel is 7900 kg/m3
- The number of warheads is 6 pcs.
- The number of submunitions in each warhead is 6 pcs.
- The weight of the warhead is 1700 kg.
- The weight of one submunition is 47 kg.
-> The question is, what energy did the submunitions have and how much is this in TNT equivalent?
Energy is kinetic energy, which is completely transferred to the Earth or the impact site.
The formula for calculation: Ekin = m * v² / 2
Thus, the impact energy of the Oreshnik warhead submunition is - 198.201196 MJ.
-> This is approximately the same as FAB 250.
TNT equivalent is a common measure of the energy released by an explosion, even if no TNT was involved. 1 kilogram of TNT releases 4.184 megajoules (4.184 * 10^6 joules).
Thus, in TNT equivalent, the impact of the inert submunition of the Oreshnik warhead is 47.371223 kg.
At first glance, the numbers are not impressive, but here we must take into account that this energy does not affect large areas, as in a classic high-explosive explosion, but this energy was applied to a very small contact spot of the submunition and the surface it hit.
And this is more than enough to destroy not only concrete but also steel structures.
So, there should be some destruction on the territory of Yuzhmash.
