The anti-missile system, Terminal High Altitude Area Defence System, known as THAAD, has been put in place despite opposition from activists and China.
THAAD is designed to shoot enemy missiles out of the sky without detonating any warheads attached to them.
The Delta Battery, 2nd Air Defence Artillery Regiment from Fort Bliss in Texas was deployed to South Korea in April to begin moving the system into place.
The overnight operation occurred nearly a year after Washington and Seoul agreed to position the battery in a remote southeastern area to counter the growing threat from North Korea.
