Had both suggested that the Pentagon was considering installing Terminal High-Altitude Air Defense (THAAD) batteries to two sites on the West Coast to protect against attack by North Korean intercontinental ballistic missiles (ICBMs).
The United States is already shielded by the Ground-based Midcourse Defense system [3], with launch sites in Alaska and California that can fire huge missiles to intercept ICBMs in space. However, the GMD system currently has only a limited supply of forty-four, and has only hit its target in slightly over half of tests.
By contrast, THAAD is designed to smack down missiles as they plunge on their targets in the terminal phase of their trajectory, and has not failed a single interception test.
However, the deputy director of the Missile Defense Agency subsequently stated it had “received no tasking” for West Coast THAAD sites, and later Rogers appeared to deny making the claim [4].
