U.S. Missile Defense: Not as Effective As We Think

Sometime after midnight on the night of January 21, 1991, I was awoken by the sound of an air raid siren. At the time, I was sleeping in an apartment in Eskhan Village, an abandoned suburban housing area outside Riyadh that served as a barracks facility for thousands of American service members deployed to Saudi Arabia as part of Operation Desert Storm. Following protocol, I quickly donned my chemical protective ensemble, inclusive of gas mask; not following protocol, I headed up to the flat roof of the two-story building to see what was happening.

As it turned out, we were under attack. Iraq had launched four of its extended-range SCUD missile derivatives toward Riyadh. The flight paths of two of these missiles were visible to the naked eye, where residual fuel burned from the nozzle of the rocket. As part of a team of SCUD missile analysts assigned to the intelligence section of Central Command headquarters, I was fascinated by this first-hand opportunity to see the SCUD in action. The irony of being on the receiving end of the very missiles I was working to destroy barely registered before I was stunned by the sound of Patriot anti-missile batteries, staged in close proximity to the housing area, firing multiple salvos of interceptors at the incoming SCUDs. Each of the interceptors homed in on their target, their S-shaped trajectories reflecting the in-flight corrections provided by the Patriot’s target acquisition radar as it tracked the flight path of the SCUDs. With dramatic effect, the Patriot interceptors exploded along the flight path of the SCUDs, which continued on their ballistic arc before impacting somewhere on the horizon with a bright yellow-green explosion.

This wasn’t the first launch of SCUD missiles by Iraq against Saudi Arabia during the war. In the days prior, there had been several missile attacks targeting the sprawling military complex at Dhahran, all of which authorities claimed had been successfully intercepted by Patriot missiles. I had counted more than a dozen Patriot interceptor launches in the vicinity of Eskhan Village on the night of January 21, 1991; more than 35 interceptors in total had been fired in the Riyadh area that night. Reports that crossed my desk the next morning indicated that all four SCUDs targeting Riyadh had been successfully intercepted and destroyed by the Patriots, a finding which puzzled me—the Patriot intercepts I had witnessed against the two SCUDs I was able to visually track seemed to be exploding behind the SCUDs, and none appeared to stop the SCUDs from detonating on the ground. Later, as part of a team of missile specialists assembled to evaluate the SCUD missile debris from the January 21 attack, I could find no evidence of any shrapnel having impacted the body of the SCUD missile.

After the war, while serving with the United Nations Special Commission charged with disarming Iraq’s weapons of mass destruction (inclusive of its SCUD missiles), I read an article in International Security by MIT Professor Theodore Postol titled “Lessons of the Gulf War Patriot Experience.” Postol questioned the Patriot’s 96 percent success rate claimed by the Army during the Gulf War. Later, while working with Israeli intelligence on the Iraqi SCUD problem, I was able to speak with members of the Israeli Defense Force who were able to confirm Professor Postol’s findings: The Patriot missile defense system successfully intercepted less that 10 percent of the SCUDs fired at Saudi Arabia and the Gulf Arab States during the Gulf War, and only 2 percent of those fired at Israel.

The failure of the Patriot missile defense system to perform during the Gulf War has been largely ignored. The reasons for this are many and varied. There was an extensive and intensive effort undertaken by the Raytheon Company (the manufacturer of the Patriot missile), the Army, and the Department of Defense to challenge Postol’s findings, thereby muddying the waters. The fact that Iraq’s SCUDs were inaccurate and did not carry WMD likewise skewed public opinion—a dud warhead landing somewhere in the desert or ocean did not generate the kind of excitement of a chemical warhead landing in a densely populated area. In the quarter of a century that has passed since the Gulf War, the performance of the Patriot has improved, as has missile defense in general. (Witness the success of Israel’s “Iron Dome” system.) But the fact remains that, at the time of the Gulf War, the Patriot was a largely untested system which failed to perform as needed. Had Iraq had better missiles, or if they had been tipped with chemical, biological, or nuclear warheads, this failure could have been catastrophic.

My experience with the Patriot missile during the Gulf War has colored my assessment of the deployment of America’s new front-line missile defense weapon, the Terminal High Altitude Area Defense system (THAAD) to South Korea. The THAAD is intended to defend against the threat posed by North Korean short- and medium-range ballistic missiles. Like the Patriot missile of 1991, the THAAD has only been tested under carefully scripted peacetime conditions, with launch crews having the advantage of long flight times (easy to track) and medium speed closure rates (easy to kill) involving single missile launches. The THAAD has not been tested under realistic wartime conditions, involving large salvos of missiles possessing high-closure rates of speed. In war, it is the unexpected that trips you up. During Desert Storm, the structural failure of Iraq’s extended-range SCUDs caused the warhead to separate from the main body of the missile, creating multiple targets the Patriot radar was unable to discriminate against. This, combined with the higher-than-anticipated closure speeds of the longer-range missiles, contributed to the poor performance of the Patriot system.

North Korea has demonstrated the ability to conduct simultaneous launches of up to four ballistic missiles. Given their proximity to South Korea, these weapons would be tracked for a far shorter time with closure speeds greater than the missile targets the THAAD has been tested against to date. Moreover, the North Koreans have demonstrated a high-loft launch profile, which would have the missile closing in on its target at a far steeper angle, and at much higher speeds, than the conventional ballistic trajectories the THAAD has trained against. The THAAD interceptors are tied to the high-tech AN/TPY-2 target acquisition radar, which can cover a 120-degree frontage. North Korea’s newly proven submarine-launched ballistic missile capability provides Pyongyang with a capability to maneuver behind the surveillance arc of the THAAD’s radar. Such an attack presumes that neither the South Korean or U.S. naval forces would detect and destroy a North Korean submarine attempting such an attack, or that the U.S. Navy’s Aegis missile defense system would fail to intercept a launched missile. The point here isn’t the likelihood of North Korean success, but the reality that the THAAD is not omnipotent.

Perhaps the greatest threat facing the THAAD, or any defensive system currently deployed in the vicinity of South Korea, is that North Korea could employ a ballistic missile tipped with a nuclear warhead for the purpose of generating a massive electromagnetic pulse (EMP) that would knock out the THAAD’s radar and electronics—along with most, if not all, of South Korea’s and America’s electrical systems stationed in the region. The likelihood of such a scenario seems slim, given the consequences North Korea would endure in the aftermath of any use of nuclear weapons. However, the fact remains that the one attack the THAAD is specifically deployed to prevent—that of a nuclear-tipped North Korean missile—is the one attack that could be its undoing.

Missile defense has always been more theoretical than practical. The Anti-Ballistic Missile (ABM) systems of the Cold War were never used, and eventually mothballed. The Patriot failed miserably during the Gulf War, only to succeed a decade later during the 2003 invasion of Iraq by using a much-improved interceptor against a far less capable foe. The much-vaunted Israeli “Iron Dome” missile defense system performed well against the homemade rockets of Hamas, but has yet to be tested against the much more capable arsenal possessed by Hezbollah—or, for that matter, Iran. The THAAD system is a 30-year-old technology untested in combat, under-tested in peacetime, and is our only line of defense against a North Korean ballistic missile threat that has taken the world by surprise in terms of its scope, breadth, and capability.

During the Gulf War, the Patriot’s poor performance did not have any strategic consequences—28 Americans tragically lost their lives when a SCUD hit their barracks, and a few Israelis died of heart attacks. The absence of a tangible result wasn’t from a lack of effort on the part of Iraq—Israeli’s Dimona nuclear reactor was targeted multiple times, and had any missile caused significant Israeli casualties, Israel would have entered the conflict, placing the delicate coalition President George W. Bush had built at risk, and perhaps changing the outcome of the war. There is little reason to believe that North Korea’s missiles lack accuracy, that their targeting will lack purpose, or their warheads will be benign. Whether or not THAAD is up to the task of protecting the South Korean peninsula (or, for that matter, Guam, Japan, and Alaska) from any North Korean ballistic missile attack is still yet to be seen. However, if history is any indication, the likelihood is that the THAAD will significantly underperform—a possible outcome American military and civilian planners should take into consideration when plotting their next moves against Pyongyang.
