Common Questions

What is Arrow-3?: Arrow-3 is Israel's exo-atmospheric Ballistic missile interceptor, developed jointly with the United States. It intercepts Ballistic Missiles above the atmosphere during their mid-course phase and has been operational since 2017, forming the top tier of Israel's layered air defence alongside David's Sling and Iron Dome.Source: Israeli Ministry of Defence / MDA
Is Israel running out of Arrow-3 missiles?: Yes. US officials cited by Semafor in 2026 confirmed Israel informed Washington it was critically low on Ballistic missile interceptors. Israel's cabinet subsequently approved NIS 2.6 billion (~$826 million) in emergency defence procurement to address the shortage.Source: Semafor
Has Arrow-3 failed to intercept Iranian missiles?: Yes. Near Dimona, interceptors launched but failed to hit incoming threats, resulting in ground impacts. Cluster missile salvos in 2026 also produced confirmed impacts in central Israeli towns, indicating the system was overwhelmed or unavailable.Source: IDF / Israeli firefighters
What is the difference between Arrow-3 and Iron Dome?: Arrow-3 intercepts Ballistic Missiles above the atmosphere at long range. Iron Dome intercepts short-range rockets and artillery shells inside the atmosphere. David's Sling handles medium-range threats between them. Together they form three distinct layers of Israel's air defence.Source: Israeli Ministry of Defence
How much does an Arrow-3 interceptor cost?: Each Arrow-3 interceptor costs an estimated $2-3 million. Iran's Ballistic Missiles cost significantly less, giving Tehran an economic advantage in a war of attrition designed to exhaust Israel's finite interceptor stocks.Source: CSIS / open-source defence analysis

Background

Arrow-3 is Israel's uppermost layer of air defence, designed to intercept Ballistic Missiles above the atmosphere during their mid-course phase. Jointly developed by the Israel Defense Forces (IDF) and the United States' Missile Defense Agency, it entered operational service in 2017. Built by Israel Aerospace Industries with Boeing as the US partner, it sits atop a layered shield alongside David's Sling for medium-range threats and Iron Dome for short-range rockets.

Arrow-3 faced its most demanding test during the 2026 Iran-Israel conflict. Iran's escalating use of one-tonne warheads and clustered salvos exposed the system's finite magazine: US officials told Semafor that Israel had informed Washington it was critically low on ballistic missile interceptors . Israel's cabinet approved NIS 2.6 billion in emergency procurement to address the shortage . Interceptor failures near Dimona confirmed the system was stretched .

The core tension is one of attrition. Each Arrow-3 interceptor costs an estimated $2-3 million; Iran's Ballistic Missiles cost a fraction of that. Sustained Iranian salvos have forced Israel to confront whether production rates can keep pace with expenditure, raising questions about the long-term viability of interceptor-led defence against a determined adversary with an asymmetric cost advantage.

How the World Sees Them

Iran

Tehran's strategy of sustained, clustered ballistic salvos using one-tonne warheads is designed to exhaust Israel's finite interceptor magazine at an asymmetric cost. Documented failures near Dimona and central Israel in 2026 validated this attrition doctrine.

Israel

Arrow-3 is the cornerstone of Israel's defence against long-range ballistic missiles, jointly funded with the US since the 1990s. The 2026 Iranian campaign has depleted stocks to critically low levels, triggering emergency NIS 2.6 billion procurement.

Saudi Arabia

Riyadh operates its own Patriot-based layered defence and has watched Arrow-3's performance closely, since Iranian ballistic missiles targeted Saudi cities in parallel salvos throughout 2026, raising similarly urgent questions about interceptor magazine depth and replenishment timelines.

United States

Washington co-developed and co-funds Arrow-3 through the Missile Defense Agency, viewing it as a model for layered ballistic missile defence. US officials sounded the alarm when Israel disclosed its interceptor shortfall to Washington in 2026.
