Dozens of state-of-the-art American fighter jets, including F-22 raptors and F-35s, are blazing across the skies surrounding the Korean peninsula.
Their goal in this training exercise is to take out key North Korean nuclear facilities.
Scores of fighter jets neutralize hostile threats, while escorting bombers to their designated targets north of the border.
The bombers drop their bombs, demolishing all targets.
The simulation of a possible war-time scenario is part of the major air force exercise dubbed Vigilant Ace.
It comes less than a week after North Korea launched its newly developed inter-continental ballistic missile.
The five-day exercise is the largest ever combined air force drill between the two allies, involving 230 warplanes and around twelve-thousand personnel.
"The exercise is held annually. We hold it to enhance our joint operations capabilities."
Six F-22s and six F-35s have been deployed to the Korean peninsula, marking the first time the highly-advanced jets have cruised the skies above Korea at the same time.
Other U.S. assets include two B-1B bombers and six Growler electronic warfare jets as well as dozens of F-15s and F-16s.
South Korea has deployed 90 fighter jets, including its F-15 and FA-50 fighters.
North Korea condemned the drills on Sunday saying they could lead to an all-out provocation that may lead to a nuclear war.
Running a commentary in North Korea's state-run Rodong Sinmun on Sunday, Pyongyang said "such a drill is a dangerous provocation as it's driving tension on the Korean peninsula to the brink of a war", and that both "South Korean and the U.S. puppet forces are foolish to run amok with such stealth fighters."
