Defense dodging
Tensions have raised considerably on the peninsula since Pyongyang allegedly successfully tested a hydrogen bomb in January.
North Korea has also ramped up missile tests as negotiations between South Korea and the US to deploy the Terminal High Altitude Area Defense system (THAAD) have progressed. South Korean Defense Minister Han Min-koo said last month that THAAD is expected to be fully deployed by the end of 2017.
The simplest way to bypass a missile defense system is to just launch more missiles than it can effectively intercept, says Jeffrey Lewis, director of the US-based East Asia Nonproliferation Program.
“Launching them simultaneously is more difficult for a missile defense system,” he says. Monday’s test involved three missiles, compared to just one test-fired on Kim Jong Un’s birthday in April.
If those missiles are equipped with nuclear warheads “they don’t have to get too many up in the air and past the missile defense system to have an effect,” Lewis says.
THAAD beater
Lewis pointed to another way North Korea can potentially bypass THAAD’s defenses: via a submarine-launched ballistic missile.
Pyongyang appears to have successfully tested such a missile last month, much to the jubilation of Kim, as seen in photos released by North Korean state media.
