Israel-Hamas War Revives Interest in U.S. Production of Iron Dome Missiles
U.S. invested in homegrown system better suited for potential conflict in Pacific than in Middle East

Israel’s war with Hamas has revived dormant U.S. interest in producing munitions for Israel’s Iron Dome missile defense system, U.S. Army and industry officials said, a development that would help a U.S. regional ally resupply for future conflicts.

Any U.S. manufacturer of Tamir interceptors would take months to get moving. But with Hamas and Hezbollah firing hundreds of rockets at Israeli military sites and cities every day, Israel’s stockpile of interceptor missiles is dwindling.

The new interest in production of Tamir interceptor missiles for the Iron Dome system comes two years after the Army passed over the Israeli hardware in favor of a U.S.-made system it deemed better suited for conflict in the Pacific.

Israel’s Iron Dome missile-defense system is one of the most battle-tested in the world, successfully destroying thousands of shells and rockets since its 2011 deployment and preventing mass civilian casualties.

“Iron Dome has proven itself over the years,” said Tom Karako, a missile defense researcher at the Center for Strategic and International Studies. “It’s no slight that it can’t contend with an overwhelming number of threats.”

To help out, the U.S. Army is now sending back to Israel two Iron Dome units it acquired three years ago, alongside more than 200 Tamir missiles the U.S. had stored in its arsenal. The two units had been deployed after being tested in Guam.

The mobile Iron Dome is Israel’s last layer of air defense and can intercept targets up to 40 miles away. Each of the 10 batteries covers an area of about 60 square miles, and includes a radar and control system to identify incoming threats and fire only on those expected to reach populated or vulnerable areas, limiting how many missiles are required.

‘Affordable mass’
The Tamirs use a home-produced rocket motor that hasn’t suffered the level of supply-chain disruption that limited production of Javelins and the advanced guided missiles the U.S. has sent to Ukraine.

“They have a very capable military and they have their own stockpiles,” Army acquisition chief Doug Bush said earlier this month of Israel.

Meanwhile, militaries around the world, including the Pentagon and Israel, are moving to secure additional production of munitions. The vast consumption of artillery shells and guided missiles in Ukraine and of Tamir interceptors in Israel recently has honed defense officials’ focus on building “affordable mass”—a reliable arsenal of heavily used munitions.

In 2020, Rafael Advanced Defense Systems and RTX Corp. announced plans to build a factory in the U.S. to assemble Tamirs.

But the following year, the Army passed over Iron Dome in favor of the Enduring Shield system made by U.S.-based Leidos, following a shoot-off in the New Mexico desert. Rafael and RTX’s new Tamir factory didn’t materialize.

The Pentagon’s push for more-sophisticated weapons and equipment to deter the perceived threat from China led the Army to favor the new U.S.-developed system seen as better able to tackle faster-moving cruise missiles over the bigger distances of the Pacific.

The Army called Iron Dome an interim solution and didn’t buy more than two, opting for the different capabilities of Enduring Shield, even though it has yet to be fielded.

“These are some of the growing pains of neglecting air defense for way too long,” said Karako.

Rafael and RTX declined to comment on Tamir production rates or on any new U.S. facility.

The Pentagon already funds much of Israel’s Iron Dome production and expenses under an existing agreement between the countries, which lawmakers have said was another catalyst for U.S. production.

RTX already makes around 70% of the Tamir, according to the companies, and has been investing heavily in expanding its missile facilities around Tucson, Ariz., which analysts said was one possible site for a Tamir line.

The Marine Corps is also looking to acquire some Iron Dome systems as well as around 1,800 Tamir missiles, according to budget documents.

Enduring Shield can be adapted to use other interceptors, including a version of the Tamir called SkyHunter.
