The US Air Force Just Tested A Ballistic Missile

The US Air Force Just Tested A Ballistic Missile
It currently has about 450 Minuteman III missiles in its arsenal.

The U.S. Air Force tested an unarmed intercontinental ballistic missile early Wednesday morning in California. 

The Minuteman III missiles are tested about four times a year. The last one occurred in February. 

The launches ensure the missiles are still operating properly, and they show off the country's nuclear capabilities. 

Wednesday's test just so happens to coincide with rising tensions over North Korea's recent missile tests. 

North Korea has conducted numerous test launches in 2017. The latest one occurred April 16, and it exploded only seconds after launching. 

All 100 U.S. Senators were invited to a White House briefing on North Korea on Wednesday. 

The U.S. currently has about 450 Minuteman III missiles in its arsenal. 

Wednesday's missile launch took place at Vandenberg Air Force Base.
