Re: What do you think of the current revolution in Egypt?
thankfully nukes are being replaced with better weapons
http://en.wikipedia.org/wiki/Kinetic_bombardment
"Since in order to reach an object in orbit it is necessary to attain an extremely high velocity, their released kinetic energy alone is enough to destroy their target; explosives are not necessary. For example: the energy of TNT is 4.6 MJ/kg, and the energy of a kinetic kill vehicle with a closing speed of 10 km/s is of 50 MJ/kg."
"A kinetic projectile can also be dropped from aircraft. This is applied by replacing the explosives of a regular bomb e.g. by concrete, for a precision hit with less collateral damage. A typical bomb has a mass of 900 kg and a speed of impact of 800 km/h (220 m/s). It is also applied for training the act of dropping a bomb with explosives. [1] This method has been used in Operation Iraqi Freedom and the subsequent military operations in Iraq by mating concrete-filled training bombs with JDAM GPS guidance kits, to attack vehicles and other relatively "soft" targets located too close to civilian structures for the use of conventional high explosive bombs."
very interesting
125x1400 mm (shell of a tank) 1700 m/s 6120 km/h 1.4 MJ/kg
Exoatmospheric Kill Vehicle closing speed roughly 10 km/s ~36000 km/h ~ 50 MJ/kg
tank shells are 18kg each so that gives 25 MJ impact
to equal that you only need a 500 gram projectile @ 6 times faster lol
