Impressive photos of the US and South Korea's massive air drills that should have North Korea on edge

The US and South Korea's annual air drills - known as Vigilant Ace - are underway in the Korean Peninsula.

This week will see 230 warplanes, from both the US and South Korean Air Forces, fly over eight US and South Korean military bases.

The drill will also involve two dozen stealth jets - a sign that the US and South Korea are forces to be reckoned with.

The show of force involves 12,000 personnel and some of the most advanced aerial weaponry in service. The drill comes as North Korea has recently become increasingly aggressive with its most recent ICBM test and rhetoric.
