Our missile defense systems are no match for hypersonic weapons
A Mitchell Institute for Aerospace Studies paper makes a complete and compelling case for why the United States should aggressively pursue hypersonic weapons, systems that travel faster than five or six times the speed of sound.
Hypersonics, the authors conclude, would afford the U.S. with unprecedented rapid reach, global target access, a “fourth dimension effect” by effectively shrinking a foe’s decision-making window and a complete rendering of existing air defenses to be obsolete.
What may not be obvious to U.S. policymakers is the corollary: Hypersonic weapons can provide these very same advantages to our adversaries. In fact, given the state of hypersonic weapons development in Russia and China, they already do.
Russian and Chinese research, test and development of hypersonic weapons have far outpaced that of the United States. A Russian hypersonic glide vehicle (HGV), known as the Avangard, completed a successful flight test in December in which the weapon purportedly reached 27 times the speed of sound. The Russians also claim this system is now in production and ready to be fielded.
The Chinese have been even more aggressive in their pursuit of hypersonic weapons. According to Undersecretary of Defense for Research and Engineering Dr. Mike Griffin, China has conducted "more tests in the past year than the United States has conducted over the past decade,” and it has achieved an initial operating capability with these weapons.
The United States, on the other hand, currently has no such capability. The stark reality is that our current missile defense systems, as well as our operational mindset, are simply incapable versus this threat.
What many in Congress may not understand is that HGVs are specifically designed to exploit gaps and seams within our current missile defense structure.
The Missile Defense Agency’s (MDA) array of satellite sensors, sea-borne and terrestrial radars, and ground-based interceptors are designed against a singular threat — an incoming ballistic missile launched from North Korea or perhaps Iran.
