Awww yes, here’s one of my personal favorites. The nuke-level hand grenade.
No, I don’t know what HIEX stands for. And more like holy **** hand grenade amirite?
I’m gonna stick with number crunching.
As we’ll shortly see, this is more of a tactical nuclear weapon. Saying it’s a grenade is like saying a railgun is pointy-rock-throwing-device.
The M67 fragmentation hand grenade has a kill radius of 15 meters and a blast radius of 45 meters or so (although shrapnel can be found over 200 meters away). Let’s see how much Elysium! technology has progressed!
This thermal grenade has a blast radius of 4 kilometers. That’s very unspecific (you’ll see why shortly) and since this is a thermal grenade, I’m going to take some liberties with my following calculations. The follow information was all derived using Nukemap, which I highly recommend to simulate big explosions.
If we assume a surface detonation (as this still is technically a grenade) and take the blast radius to be edge of where you have the thermal radiation radius (i.e inside this, you get third degree burns), we have a grenade with a yield of 105 kilotons (i.e. 105,000 tons of TNT). If we assume a surface detonation and take the blast radius to be where there is 4.6-5 psi overpressure (this is actually called an air blast radius: in this zone, most buildings collapse, everyone in this zone is injured and a lot of people end up dead), we end up with a grenade with a yield of 750 kilotons. If we assume a surface detonation and take the blast radius to be where there is 20 psi overpressure (again, this is actually called an air blast radius: in this zone, heavily built concrete buildings are severely damaged or destroyed, and damn near everyone is dead), we end up with a grenade with a yield of 6.38 megatons, or 6380 kilotons, or over 6 million tons of TNT.
For reference, on the low-end (105 kiloton thermal grenade), if you detonate the thermal grenade near the Verizon Center/Ford’s Theater, the White House is getting a fatal dose of radiation and (being damn close to the 20 psi overpressure zone) is probably gonna get seriously damaged or flattened (talking about the main superstructure and not any hidden bunkers, etc.).
On the high end (6.38 megatons of TNT), detonating that thermal grenade in the same spot, everyone in a 23.7 km radius is getting 3rd degree burns, and an estimated 184,000 people die (as a direct cause of the nuke, not counting long-term effects).
All of this in a thermal hand grenade which can be set to have a minimum blast radius of 40 meters. Dial-a-nuke kids!
And this very well might be standard infantry stuff.
