The U.S. Air Force says it successfully launched an unarmed intercontinental ballistic missile during a test Wednesday morning.
This is the fourth time the U.S. tested a Minuteman III missile in 2017.
The launches ensure the missiles still work, while also showing off U.S. nuclear capabilities.
This most recent launch comes just days after North Korea test-launched a missile July 28.
In response, the U.S. and its allies flew supersonic bombers and fighter jets over the Korean Peninsula on Saturday.
A few days later, Secretary of State Rex Tillerson said the U.S. would be up for diplomatic talks if North Korea stops its missile program.
"We do not seek an excuse to send our military north of the 38th parallel. And we're trying to convey to the North Koreans we are not your enemy, we are not your threat, but you are presenting an unacceptable threat to us, and we have to respond," Tillerson said during a press briefing Tuesday.
