The U.S. military successfully test-launched an Intercontinental Ballistic Missile from California early Wednesday, according to an Air Force spokesman — just days after North Korea's second test of an ICBM, ABC reported.
The unarmed Minuteman III missile was launched at 2:10 a.m. PT from Vandenberg Air Force Base, about 130 miles northwest of Los Angeles.
An Air Force statement said that the test was not a response to recent North Korean actions, but shows that America's nuclear enterprise is "safe, secure, effective and ready to be able to deter, detect and defend against attacks on the United States and its allies."
The ICBM was equipped with a test reentry vehicle, which officials said showed it traveled about 4,200 miles to the Kwajalein Atoll in the Marshall Islands.
The operation was conducted by a team of Air Force Global Strike Command Airmen from the 90th Missile Wing, along with the 576th Flight Test Squadron and the 30th Space Wing stationed at Vandenberg.
"These test launches require the highest-degree of technical competence and commitment at every level," Col. Michael Hough, the 30th Space Wing commander and launch decision authority, said in a statement.
Air Force Global Strike Command has tested 299 Minuteman III ICBMs over the program's history. The Minuteman III's are the U.S. military's only land-based ICBMs. Another one was tested earlier this year in February from Vandenberg.
The U.S. military schedules four test-launches each fiscal year, with the actual schedule plotted out several years in advance — so it's unrelated to recent events, Air Force Capt. Michele Rollins, a spokesperson for the strike command, told CNBC.
Last week, North Korea tested an ICBM for the second time. The missile flew for 45 minutes and traveled more than 1,000 kilometers laterally, defense officials and analysts said. U.S. officials believe the missile broke up upon re-entering the atmosphere.
The United States and its allies flew supersonic bombers and fighter jets over the Korean Peninsula in a 10-hour show of force Sunday against North Korea following the country's latest ICBM launch.
The U.S. B-1 bombers first flew over Japanese airspace, where they were joined by two Japanese F-2 fighter jets, before flying over the Korean Peninsula with four South Korean F-15 fighter jets, U.S. Pacific Air Forces said in a statement.
The Air Force said the 10-hour mission was a direct response to North Korea's two ICBM tests this month, including the latest on Friday.
Analysts say the North's test Friday showed that a broader part of the mainland United States, including Los Angeles and Chicago, is now in range of Pyongyang's weapons.
Asked about possible U.S. military action against North Korea, White House Press Secretary Sarah Huckabee Sanders reiterated on Tuesday that "all options are on the table" but the administration would not "broadcast what we're going to do."
