Arrow-3 vs David's Sling: Side-by-Side Comparison & Analysis
Overview
In this side-by-side comparison, we analyze the key differences between Arrow-3, Israel's exoatmospheric kinetic kill vehicle interceptor, and David's Sling, a medium-to-long-range air defense system. Understanding the strengths and weaknesses of each system is crucial for defense planners to make informed decisions about which system to choose for specific scenarios.
Side-by-Side Specifications
| Dimension | Arrow 3 | Davids Sling |
|---|---|---|
| Type | Exoatmospheric kinetic kill vehicle interceptor | Medium-to-long-range air defense system |
| Origin | Israel – IAI/Boeing joint development | Israel – Rafael/Raytheon |
| Operators | Israel | Israel, Finland (ordered) |
| Range (km) | 2400 | 300 |
| Speed | Mach 9+ | Mach 7.5 |
| Guidance | Two-color infrared seeker with mid-course datalink updates from Green Pine radar | Dual-mode RF/EO seeker (Stunner interceptor) |
| Warhead | Hit-to-kill kinetic energy (no explosive warhead) | Hit-to-kill (Stunner), fragmentation (SkyCeptor) |
| First Deployed | 2017 | 2017 |
| Unit Cost (USD) | ~$3M per interceptor | ~$1M per Stunner interceptor |
| Significance | Only operational exoatmospheric interceptor outside US SM-3. Intercepts ballistic missiles in space before reentry, providing widest defensive footprint of any Israeli system. | Fills gap between Iron Dome (short-range) and Arrow (long-range). Designed specifically to counter Hezbollah's heavy rocket and cruise missile threat. |
