The Iron Dome Military Revolution By Michael Oren

Historically, defensive measures lag behind offensive capabilities. Not so with Israel’s new antimissile system.

Two hundred years ago, during the War of 1812, British cannonballs slammed into the hull of the USS Constitution—and bounced off. “Huzzah,” an American sailor shouted, “Her hull is made of iron!” In fact, “Old Ironsides” was constructed of sturdy pine and oak, and real ironclad ships didn’t appear until a half-century later, when the Confederate Merrimack battled the Union’s Monitor to a stalemate. Not even the most powerful shell could penetrate either warship’s armor—a breakthrough in defensive technology.

Such revolutions are rare. Throughout the ages, defense has lagged behind offense. Medieval rulers thickened and angled their castles’ walls to withstand and deflect artillery, but the walls inevitably crumbled. Knights tempered their armor only to be felled by crossbows and muskets. Allied tanks subdued German trenches in World War I, and German tanks in World War II outflanked France’s Maginot Line.

Defenders were especially helpless against rockets, from the Nazi V-1s and V-2s to Iraqi scuds. When Iranian-backed terrorists in Lebanon and the Gaza Strip started firing thousands of rockets at Israel, the Israeli military was forced to mount costly counterstrikes in 2006 and 2008.

But today, the attacked in Israel are now trumping their attackers. That is because, in the spirit of Old Ironsides and the ironclads, Israel developed the Iron Dome antimissile system.

From drawing board to deployment in 2011, Israel completed the Iron Dome in a mere three years. The first two batteries—developed and financed entirely by Israel—took down dozens of Hamas rockets, making Iron Dome the first antimissile system ever to succeed in combat. The generous support of President Obama and the U.S. Congress enabled the construction of four additional batteries. Ultimately, 10 to 13 batteries and a full complement of interceptors will be needed to defend the entire country.

Intercepting supersonic projectiles in midflight is literally rocket science. Israeli engineers pulled off the feat by combining cutting-edge tracking radar with electro-optic sensors and mounting them on highly mobile, all-weather air-defense systems. Iron Dome can hit multiple types of rockets and missiles at ranges of up to 75 kilometers. It can also be relocated swiftly to new sites and radically different terrain. (As part of our vast alliance with the United States, we have offered to share this pioneering technology.)

Most ingeniously, the Iron Dome determines within split seconds whether an incoming rocket is headed for an open space or a populated area—and saves its fire for the latter case. Millions of Israelis live within the terrorists’ range, with as little as 15 seconds to reach a bomb shelter.

By neutralizing most rockets headed for populated areas, the Iron Dome gives decision makers invaluable time to find diplomatic solutions. If salvos of rockets were pummeling Israeli homes, hospitals and schools, Israeli leaders would be under immense pressure to order ground operations that could yield significant casualties. By denying the terrorists a decisive offensive advantage, Iron Dome will save lives and prevent wars.

Before Israel’s recent Operation Pillar of Defense, Gaza terrorists fired some 700 rockets and mortars at southern Israel, many of which were taken out by Iron Dome. Still Israel was forced to take action, mounting precise sorties against terrorists and launch sites. In turn the terrorists fired 1,500 rockets, some aimed at Jerusalem and Tel Aviv. These might have inflicted severe human and material loss, but Iron Dome downed nearly 85% of those headed toward populated areas.

Combined with Israel’s world-class civil-defense system, Iron Dome thwarted the terrorists’ aim to wreak intolerable damage. Consequently, Israeli leaders had the time and space needed to join with U.S. Secretary of State Hillary Clinton and Egyptian President Mohammed Morsi in working out a cease-fire. More than 50,000 Israeli reservists who had assembled on Gaza’s border returned peacefully to their families.

Iron Dome is thus a game-changer, but it isn’t a game-ender. Terrorists on our borders have more than 70,000 rockets, and 15 of every 100 fired can still get through the Iron Dome. The danger even of conventional warheads is unacceptable, but nuclear warheads would pose an existential threat. That is why, together with the U.S., Israel has developed the Arrow to intercept orbital and suborbital ballistic missiles, and we have successfully tested David’s Sling, a long-range rocket-defense system.

These innovations will not only protect Israel but enhance security for America and its allies world-wide. Yet no air-defense system is foolproof, and robust offensive capabilities remain necessary to protect Israelis from harm. Iron hulls once made war ships invulnerable, but the skies cannot be armored. At least Iron Dome, along with Arrow and David’s Sling, makes them safer.

Mr. Oren is Israel’s ambassador to the United States.
