David’s Sling: the interceptor that stops what Iron Dome was never built to catch
In short: David’s Sling covers the gap between short-range rockets and long-range ballistic missiles. It intercepts targets from roughly 40 to 300 kilometers using the Stunner missile, and it entered service in 2017 after Rafael and Raytheon spent years building it.
Ask anyone about Israeli air defense and you get one answer. Iron Dome gets the headlines, the viral videos, the credit. But it was designed for short-range rockets and mortars flying up to about 70 kilometers. Anything faster or farther slips past its job description. That middle band is where David’s Sling lives.

What the middle layer actually does
David’s Sling sits between the two extremes of a layered system. Below it, short-range interceptors handle Qassam-style rockets. Above it, Arrow 2 and Arrow 3 handle long-range ballistic missiles outside the atmosphere. David’s Sling fills the space in between, targeting large-caliber rockets, cruise missiles, drones, and medium-range ballistic missiles.
The engagement envelope runs roughly 40 to 300 kilometers. Its interceptor, the Stunner, uses no warhead. It destroys the target by hitting it directly, a hit-to-kill approach that relies on a dual-seeker nose combining radar and an electro-optical sensor. That precision matters when a single incoming missile carries a heavy payload.
Who built it and when
The system is a joint project of Rafael Advanced Defense Systems and the American firm Raytheon. Development started in 2006, and David’s Sling reached operational status with the Israeli Air Force in April 2017. The program was funded in large part by the United States, the same partnership model that shaped Israel’s broader missile defense architecture.
Its first confirmed combat interception came in 2018, against Syrian tactical missiles. Since then it has been used against threats that the lower layers of short range air defense cannot reach.
How the layers compare
Each layer has a narrow, deliberate purpose. Overlap between them is intentional, so a target that leaks through one system can still be caught by another.
Why it matters more than the coverage suggests
The threats David’s Sling was built for are the ones that changed. Hezbollah’s arsenal in Lebanon includes tens of thousands of rockets, and a growing number reach well past Iron Dome’s ceiling. Precision-guided munitions and cruise missiles fly at altitudes and speeds that a short-range interceptor was never tuned for.
Consider what the system covers in practice:
- Large-caliber rockets with ranges beyond 70 kilometers
- Cruise missiles flying low to evade radar
- Medium-range ballistic missiles below the Arrow threshold
- Drones and unmanned aircraft used for strikes
- Salvos aimed at cities and strategic infrastructure
The economics cut both ways. A single Stunner reportedly costs around one million dollars, far more than an Iron Dome Tamir interceptor. That price is why doctrine reserves David’s Sling for the threats that genuinely warrant it, rather than firing it at cheap rockets the cheaper layer can handle. Command decisions about which layer engages a target happen in seconds.
