America's Missile Shield Is Running Low
Iran's multi-domain attacks burned through interceptor stockpiles fast. Now the Pentagon and industry face a reckoning over cost, capacity, and what comes next.

America's air-and-missile-defense systems worked. That's the problem. [1] Defending against waves of cruise missiles and Shahed drone swarms demanded a relentless pace of fire — and interceptors burned through at an alarming rate. [1] The loss of THAAD/TPY-2 radars compounded the pressure, forcing the US to scramble to protect remaining assets across the Middle East. [1]
Iran's salvo wasn't a single punch. It was architecture. [1] Rob Mitrevski, president of Golden Dome strategy and integration at L3Harris, described it plainly: "Iran had a real capability in deploying and launching a multitude of well-stocked multi-domain threats, ranging from several classes of missiles through several classes of UAVs." [1] "We saw a significant number of them deployed concurrently and set to hit their targets within short time frames. The Iranian threat was unique in that it challenged the defender to defeat low-cost threats with low-cost defensive means, and defeat high-cost, more capable threats with more capable effectors." [1]
The cost asymmetry sits at the center of every honest conversation about AMD. The rise of UAS swarms — mostly Iran's Shahed, which has a cost per drone measured in the tens of thousands — is quickly changing the calculations around the cost of interception. [1] Interceptors cost orders of magnitude more. [1]
Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies, is direct about where the debate gets muddled. [1] "The thing that's not appreciated is everybody keeps repeating the same tired cliche and headline about you shouldn't kill a $40,000 drone with a $4,000,000 missile," he said. [1] His prescription: "Well, then start buying more of the kind of UAS things that are already available, already fielded and already operational. Just go and turn up the volume dial on that." [1]
The gap between knowing a problem and acting on it is where strategy goes to die. The architecture of modern air defense was built for a different threat profile — and the industrial base that supplies it was sized accordingly.
Karako is blunt about why the funding picture looks the way it does. [1] Inconsistent demand signals for AMD systems and components has led to less production over time, and all of these factors combined have helped lead to dwindling stockpiles and a need for a rapid increase in industrial base capacity and production. [1]
The production constraints are structural. [1] Solid-rocket motors for interceptors require a complex manufacturing process. Building a THAAD/TPY-2 radar is an extended, multi-billion-dollar task. [1] These aren't components you commission on a six-month timeline. Mitrevski frames the strategic implication: "The multi-domain, concurrent attack capability on a diverse set of targets with significant numbers of weapons is the type of scenario we're going to have to get used to thinking about." [1]
Three concerns now dominate AMD planning: cost, effectiveness, and industrial base capacity. [1] Managing all three demands coordinated commitment from both the Pentagon and industry. [1] On paper, alignment exists — both sides broadly agree on what is needed. The harder question is whether the demand signals will hold long enough for manufacturers to retool and scale. [1]
What the Iran conflict clarified is that the future of missile defense isn't a single intercept — it's a sustained manufacturing and fielding competition waged before the first salvo ever launches.
Karako's summary of where the US now stands is spare and unambiguous: [1] "We needed to do a munitions ramp before we vaporized a couple trillion dollars of interceptors. Now we need it even worse." [1] The technology is understood. The threat is documented. What remains is the industrial will to build faster than adversaries can fire.
