The spokesman, Navy Capt. Jeff Davis, said Wednesday the missile was sacked from a mobile launcher at an aircraft plant about 100 kilometers (60 miles) north of Pyongyang, the North Korean capital.
German Chancellor Angela Merkel and South Korean President Moon Jae-in agreed on Wednesday that tougher sanctions were necessary against North Korea after it announced a test-launch of a new intercontinental ballistic missile (ICBM). Haley said the USA would propose new United Nations sanctions aimed at North Korea and called for worldwide unity and cooperation.
Haley also warned that in the coming days, the USA will bring before the Security Council a resolution that raises the worldwide response in a way that is "proportionate" to North Korea's "new escalation".
"The US is prepared to use the full range of our capabilities to defend ourselves and our allies", Haley said.
Trump has boosted the U.S.'s military presence in the region in response to reports suggesting North Korea was preparing to conduct a sixth nuclear weapons test, and North Korea has begun testing ballistic missiles at an unprecedented rate.
Wednesday's UN Security Council meeting came in response to North Korea's first ICBM test, which United States officials assess was a new kind of missile that had a range of about 5,500 kilometers (3,400 miles), capable of hitting Alaska.
Davis criticized North Korea for not following the global convention of providing advance notice of a missile launch so that commercial ships, airliners and satellites are not endangered.
If and when Trump administration officials reach the point where they have ramped up the pressure as much as they can, they will have no other option but to talk to the North Korean government. David Wright, director of the Global Security Program at the Union of Concerned Scientists, echoed NORAD's statements; however, while the missile can not reach the lower 48 states, Alaska and Hawaii are still within its effective range.
One former high-ranking intelligence official briefed on the program said the effort was stymied by North Korea's utter secrecy and extreme isolation of its communications systems.

Experts believe that, despite the test Tuesday, North Korea is still some years off being able to successfully miniaturize a nuclear warhead and mount it on an ICBM.
US President Donald Trump has not helped matters by blowing hot and cold on North Korea.
Alongside the United States, Pyongyang views its neighbors South Korea and Japan as its two other main enemies. But Trump has expressed growing irritation at Beijing's reluctance to tighten the screw on Pyongyang over its nuclear and missile programs.
Tillerson also warned that any country helping North Korea or failing to carry out United Nations restrictions on the country "is aiding and abetting a unsafe regime". "There are several options here", Siracusa said.
Haley said the United States doesn't seek conflict - "in fact we seek to avoid it".
According to these parameters the missile would have a range of roughly 6,700 kilometres if launched on a more typical trajectory, making it an intercontinental ballistic missile (ICBM), according to widely used definitions, he said. He acknowledged though that previous USA missile defense tests had shown "mixed results".
While the new United States sanctions push won backing from France, it raised immediate protests from fellow permanent Security Council member Russian Federation whose Deputy Ambassador Vladimir Safronkov warned that "sanctions will not resolve the issue".
The missile carried a re-entry vehicle, they said, which apparently was meant to demonstrate it could withstand the intense heat of a high-speed descent through the atmosphere.
