US spends $ 1,000 billion developing smart nuclear bombs

The US government is planning to improve its nuclear warheads in a smaller, stealthier and more accurate way.

When North Korea dug tunnels at its nuclear test site last fall into the spy satellite's observation, the US government is also preparing for a nuclear test in the Nevada desert, according to the New York Times.

A fighter plane flew from the Nevada desert, carrying the first fully automatic version of the atomic bomb. Modified from an old type, the design of the bomb consists of a computer brain and four mobile maneuvers of the bomb aimed at processing deep underground targets such as tunnels and weapons testing yards. The bomb's explosive power can be adjusted according to the target to minimize damage.

While North Korea claims to have successfully built the hydrogen bomb, the US Department of Energy and the US Department of Defense have prepared a series of weapons to deal with.

B61 Model 12 , which was tested last year in Nevada, was the first of five new warheads to be estimated at $ 1,000 billion in three decades. Belonging to the same group, the weapons and bombing systems aimed at small size, stealth and accuracy.

With the new version of the B6, the US military replaces the fixed tail with fins that can be controlled and equipped with many other advanced technologies. As a result, the bomb targets the target more accurately and can adjust the impact of nuclear warheads to minimize radioactive fallout and damage to the surrounding area.

In a recent report to Congress, the Department of Energy, which is responsible for upgrading warheads, said "modernization in the direction of miniaturization" is the fastest way to reduce nuclear arsenals.

However, the cost of implementing the modernization plan is a big problem. The total cost is up to $ 1 trillion if the president takes the next step and directs research into bombers, submarines and missiles, upgrading 8 factories and laboratories.
