By 25 April 2017, six trailers carrying the THAAD radar, interceptor launchers, communications, and support equipment entered the Seongju site. On 30 April 2017, it was reported that South Korea would bear the cost of the land and facilities for THAAD, while the US will pay for operating it. On 2 May 2017, Moon Sang-gyun, with the South Korean Defense Ministry and Col. Robert Manning III, a spokesman for the U.S. military announced that the THAAD system in Seongju is operational and "has the ability to intercept North Korean missiles and defend South Korea." It was reported that the system will not reach its full operational potential until later this year when additional elements of the system are onsite. On 7 June 2017 President Moon Jae-in suspended further THAAD deployment pending a review, after discovering four addition launchers had entered South Korea without the defense ministry informing him. The 35th Air Defense Artillery Brigade (United States) has integrated THAAD into its layered defense on the Korean Peninsula, denoted Combined Task Force Defender, composed of both US and ROK personnel.
