Today, the U.S. has no optimal capability to intercept an advanced hypersonic boost glide vehicle, according to an industry source. Although hypersonic vehicles burn hot and are thus easily visible to the U.S. sensor network, they are maneuverable. There is concern that existing interceptors in the U.S. arsenal lack the divert capabilities required to counter such a threat.
However, a credible threat does not yet exist. The vehicles tested by the Chinese are considered to be basic, but Missile Defense Agency (MDA) Director Vice Adm. James Syring is said to be more concerned about Russia’s hypersonic systems, which are far more maneuverable and advanced. He has already advocated quietly in the Pentagon for funding for a Thaad-ER to address what he sees as a gap in intercept capability should these threats get fielded. So far, his efforts have not paid off.
