Analysts say new North Korean missile could hit U.S.

(CBS) -- North Korean State TV announced Wednesday the rogue nation's launch of its newest and longest-range missile, the Hwasong-15.

North Koreans applauded when the report showed their leader Kim Jong-un signing the launch order.

In July, North Korea twice test fired the Hwasong-14 -- the less powerful predecessor of the new missile.

During Tuesday's launch, the ballistic missile was purposely lofted high into space and reached a maximum altitude of nearly 2800 miles. Analysts say that if it fired on a standard trajectory the missile could travel approximately 8100 miles, far enough to hit anywhere in the United States.

"It went higher, frankly, than any previous shots they've taken," says Secretary of Defense James Mattis.

The missile stayed in the air for 63 minutes before splashing into the Sea of Japan.

Shortly after the launch, President Trump said the US will "handle the threat." This morning he tweeted "additional major sanctions" will be imposed on North Korea.

The United Nations Security Council meets in emergency session Wednesday to denounce North Korea's latest act of aggression.

It's still not known if North Korea's new missile could support an actual nuclear warhead and survive reentry into the earth's atmosphere.

On Tuesday, Hawaii previewed its new emergency sirens. Officials are urging people to be prepared for a worst-case scenario.
