In July 2020 Admiral Philip S. Davidson, the head of United States Indo-Pacific Command advised that he sought funding to construct an Aegis Ashore system in Guam by 2026 both to defend existing U.S. military facilities on Guam and to provide offensive "long-range precision strike capability into the First Island Chain" dominated by China. Speaking in March 2021 Davidson said that the "Guam Defense System" of an Aegis Ashore Facility would free up three Arleigh Burke-class destroyers for service elsewhere. Davidson said that Chinese submarines and surface ships together with its ballistic missiles pose "a 360-degree threat" to Guam beyond the capabilities of the existing Terminal High Altitude Area Defense system on Guam.
