The warhead is the missile's payload, or cargo.
The warhead is set to detonate just above the target to maximise the damage.
A well-tested warhead design is both easier to hawk and more lucrative to sell.
After flying into space, the interceptor released its exoatmospheric kill vehicle, which tracked, intercepted and destroyed the target warhead.
The BrahMos can carry a 440-pound (200-kilogram) conventional warhead and has a range of 175 miles (280 kilometers).
A US national intelligence estimate two years ago said that Iran had explored nuclear warhead design for several years but had probably stopped in 2003.
There are even discussions about Britain sharing in France’s nuclear-warhead simulation testing facilities, rather than replicating them at huge cost.
There is always the possibility that the RRW will be resurrected; the Nuclear Posture Review doesn't even explicitly exclude the possibility of an RRW-like warhead.
The annexe said Iranian scientists had engaged in "probable testing" of explosives arranged in a hemisphere, which is how an implosion-type nuclear warhead is triggered.
The idea is that when hit, the metal in a projectile shorts the two charged plates together, forming a circuit and releasing a surge of electricity which can break the warhead up.
Gates says senior defense officials believe it is North Korea's "long-term intent" to attach a nuclear warhead on top of a missile, but is skeptical they have the ability to do so.
Pyongyang may also be preparing to test launch a Taepo Dong-2 missile, which could theoretically have the range to reach the continental United States with a nuclear warhead.
He needs to disarm a lost nuclear warhead (technology as danger), and while he is successful, he does not have enough oxygen left in his suit to return to Deep Core (technology as inadequate).
