The big take away for Korea watchers from this successful flight test of the THAAD missile defense system is that the threat target was an Intermediate Range Ballistic Missile (IRBM) which is the same class of missile as North Korea’s Musudan. A THAAD battery was deployed to Guam back in 2013 to defend against the Musudan threat to Guam and this flight test validates its capability to defend against this threat:
The United States said on Tuesday it shot down a simulated, incoming intermediate-range ballistic missile similar the ones being developed by countries like North Korea, in a new test of the nation’s defences.
Planned months ago, the U.S. missile defence test over the Pacific Ocean has gained significance after North Korea’s July 4 launch of an intercontinental ballistic missile heightened concerns about the threat from Pyongyang.
The test was the first-ever of the Terminal High Altitude Area Defense system against an incoming IRBM, which experts say is a faster and more difficult target to hit than shorter-range missiles.
The U.S. Missile Defense Agency said the IRBM was designed to behave similarly to the kinds of missiles that could threaten the United States.
“The successful demonstration of THAAD against an IRBM-range missile threat bolsters the country’s defensive capability against developing missile threats in North Korea and other countries,” the Missile Defense Agency said in a statement. [Reuters]
