On January 18, 1991, Iraq launched the first of 47 modified SCUD missiles at Israel and Saudi Arabia. Those attacks — largely militarily ineffective but strategically significant — launched the modern era of missile defense and set the stage for everything from Iron Dome to Arrow-3.
The Al-Hussein: Iraq's Modified SCUD
Iraq's "Al-Hussein" was a modified Soviet R-17 (SCUD-B) with extended range:
- Original SCUD-B: 300 km range, 985 kg warhead
- Al-Hussein modification: Extended fuel tank, reduced warhead to 250 kg, range increased to 600 km
- Problem: The modifications weakened the airframe, causing many missiles to break apart during reentry — which paradoxically made them harder to intercept (multiple fragments vs. one warhead)
Attack Timeline
| Target | Missiles Launched | Casualties | Notable Events |
|---|---|---|---|
| Israel | 42 (at least) | 2 direct, 11 heart attacks | Tel Aviv, Haifa targeted; Israel restrained from retaliation |
| Saudi Arabia | 47+ (at Riyadh, Dhahran, others) | 28 (Dhahran barracks) | Deadliest: Feb 25 strike killed 28 US soldiers at Dhahran |
Patriot's Controversial Debut
The US deployed Patriot PAC-1 batteries to both Israel and Saudi Arabia. The Army initially claimed a 95%+ interception rate — a claim that was later heavily disputed. Post-war analysis by MIT's Ted Postol and others suggested the actual interception rate was closer to 10% or less.
The controversy arose because:
- PAC-1 was designed for aircraft, not ballistic missiles. Its fragmentation warhead could damage but not destroy SCUD warheads.
- Many "intercepts" hit the SCUD body but missed the warhead, which continued to its target.
- Al-Hussein missiles frequently broke apart during reentry, creating multiple targets — Patriot sometimes engaged debris rather than warheads.
- Software timing errors degraded tracking accuracy over extended operation periods.
Strategic Impact
Despite their military insignificance (the 47 missiles caused fewer casualties than a single day of conventional combat), the SCUD attacks had enormous strategic consequences:
- Coalition management: The US had to deploy massive resources to prevent Israel from retaliating, which would have fractured the Arab coalition against Iraq
- Terror weapon: SCUDs caused disproportionate fear. Millions of Israelis spent nights in sealed rooms wearing gas masks.
- Patriot investment: The performance gap drove billions in missile defense investment, leading to PAC-2 GEM, PAC-3, THAAD, and Aegis BMD
- Israeli programs: Israel accelerated Arrow development, eventually creating the world's most comprehensive missile defense architecture
Lessons That Shaped Today
The Gulf War SCUD experience established principles that define current missile defense:
- Ballistic missile defense requires purpose-built systems — repurposed anti-aircraft systems (PAC-1) are inadequate
- Hit-to-kill is essential — proximity warheads don't reliably destroy missile warheads
- Early warning is critical — satellite detection of launches provides essential reaction time
- Psychological impact exceeds physical damage — even inaccurate missiles cause strategic effects
- "Left of launch" matters — destroying launchers before firing (the "Great SCUD Hunt") is more efficient than shooting down missiles
Every modern missile defense system — Patriot PAC-3, THAAD, Arrow, Iron Dome — exists in some way because of those 47 SCUDs in January 1991. The Gulf War proved that missile defense was both necessary and difficult, launching a thirty-year investment cycle that continues to accelerate.
