PENTAGON chiefs have dispatched its weirdest secret “Star Wars” weapon from Pearl Harbor in Hawaii to intercept North Korean nuclear missiles bound for California.

With its huge white globe attached to a table like structure, it has to be mankind’s wackiest looking seagoing vessel ever.

According to The Sun, America is pinning its hope on averting a nuclear apocalypse on this extraordinary self-propelled 85 metre, 50,000-tonne mammoth structure.

Called the Sea-Based X-Band Radar (SBX), it is said to be so powerful it could detect a baseball over San Francisco from the other side of the continent.

Now it has reportedly set sail from its base in Pearl Harbor – famous for Japan’s deadly surprise attack in 1941 on a US Navy base there which brought American into World War 2.

It is understood the US Government confirmed it has been deployed to the North Korean coast and local people have snapped it leaving Hawaii several weeks ago.

Its role is to defend against Kim Jong-un‘s doomsday weapons by directing interceptor rockets.

And the threat is all too real.

Rogue state North Korea conducted its fourth nuclear test in January and fifth in September in defiance of furious international reaction and stiff sanctions.

It also test-fired more than 20 ballistic missiles, including the mid-range Musudan missile, which theoretically is capable of flying as far as the US territory of Guam.

Pyongyang is thought to be working on a nuclear-tipped intercontinental ballistic missile that can hit the American mainland.

And a South Korean weapons expert has warned the secretive state could build up to 79 nuclear devices capable of turning the US into a radiation-blasted hellhole by the end of 2020.

Jong-un has made it clear he wants to do just that.

Earlier this year the madcap tyrant issued one of his most chilling threats yet, promising “doom” is “drawing near”.

A spokesperson said: “North Korean scientists are in high spirit to detonate H-bombs of hundreds of kilotons and megatons, capable of wiping out the whole territory of the US all at once.”

Because it is so secret the Pentagon is understandably tight lipped about its exact position.
