The Washington Free Beacon:
Foreign states are developing high-speed, maneuvering missiles, and the Pentagon and U.S. Pacific Command want weapons to counter them, a leading defense contractor involved in missile defense said Monday.
Doug Graham, vice president of missile systems and advanced programs for Lockheed Martin, a major defense contractor, told reporters in a briefing that missiles pose “an accelerating threat, both in numbers and complexity.”
“We’re also seeing advanced threats … hypersonic, maneuvering threats, that are being characterized as directly challenging the capabilities” of the current U.S. ballistic missile defense system, Graham said in a teleconference from Huntsville, Ala.
Current U.S. missile defenses include ship-based Aegis anti-missile systems, ground-based Terminal High-Altitude Area Defense, or THAAD, Patriot PAC-3s, and Ground Based Midcourse Defense interceptors deployed in Alaska and California that can counter any North Korean long-range missile attack.
Growing missile threats are driving the need for a greater quantity of missile defense arrays, as well as more capable systems equipped with better sensors, increased ability to detect decoy warheads, and ultimately the ability to target missiles shortly after launch when they are more vulnerable to attack–so-called “boost phase” intercept systems.
China and Russia are both developing hypersonic missiles that travel at speeds up to 7,500 miles per hour along the edge of space and have the ability to maneuver, complicating the task of intercepting them.
The Pentagon is also working on hypersonic missiles, but is investing far less than either China or Russia.
Russia conducted a flight test of its experimental Yu-71 hypersonic glider in April that was launched atop an SS-19 intercontinental ballistic missile. That test was followed three days later by China’s seventh flight test of what is called the DF-ZF hypersonic glider on a missile that flew from central China to the western part of the country. The missiles travel at speeds of between Mach 5 and Mach 10, or between 3,800 miles per hour and 7,672 miles per hour.
One system being looked at by the Pentagon’s Missile Defense Agency to counter maneuvering high-speed missiles is an enhanced version of Lockheed’s THAAD, called THAAD-ER.
The current THAAD-ER system uses a two-stage interceptor with higher velocity that would be capable of catching up to and destroying hypersonic missiles.
Laser weapons also are being considered for use against hypersonic missiles. Lockheed is working on lasers that can hit hypersonic missiles shortly after launch and before they reach ultra-high speeds, Graham said.
“We’re seeing significant interest [in THAAD-ER] from users in PACOM and other places,” he said, noting that Congress also is prodding the Pentagon to develop missile defenses against advanced threats.
“THAAD-ER is certainly one candidate and one of the more near-term options that the U.S. government has [in order] to begin addressing some of the advanced threats that are emerging,” Graham said.
The current defense authorization bill contains a provision that would require the Missile Defense Agency to set up a specific program for developing weapons to defeat hypersonic missiles.
The advanced missile threat is also driving demand in the Pentagon for laser guns, and Lockheed is working to develop a high powered laser deployed on a high-altitude, long-endurance drone aircraft. The laser would target missiles in the boost phase–shortly after launch.
