Arrow-3 vs Iskander-K: Side-by-Side Comparison & Analysis
Overview
This comparison aims to provide a comprehensive analysis of the Arrow-3 and Iskander-K missile systems, highlighting their strengths and weaknesses in various scenarios. Understanding the differences between these systems can help defense planners make informed decisions about which system to choose for specific missions.
Side-by-Side Specifications
| Dimension | Arrow 3 | Iskander K |
|---|---|---|
| Range | 2400 km | 2500 km |
| Speed | Mach 9+ | Mach 0.8 |
| Cost | ~$3M per interceptor | ~$3M per missile |
| Guidance | Two-color infrared seeker with mid-course datalink updates from Green Pine radar | INS + GLONASS + TERCOM + DSMAC + IR terminal |
| Warhead | Hit-to-kill kinetic energy (no explosive warhead) | 480 kg conventional (nuclear-capable) |
| First Deployed | 2017 | 2007 |
| Unit Cost (USD) | ~$3M per interceptor | ~$3M per missile |
| Significance | Only operational exoatmospheric interceptor outside US SM-3. Intercepts ballistic missiles in space before reentry, providing widest defensive footprint of any Israeli system. | Cruise missile variant fired from the same Iskander-M TEL launcher as the ballistic version. Carries R-500/9M728 or 9M729 cruise missiles. |
| Combat Record | First combat use April 13-14, 2024 during Iran's Operation True Promise. Intercepted Emad and Shahab-3 variants at altitudes above 100km. Confirmed multiple kills during October 2024 Iranian barrage. | Extensively used in Ukraine (2022-present). Strikes against infrastructure, military targets, and air defense systems. |
| Strengths | Intercepts in space (no debris falls on defended area), Extremely wide coverage area from single battery, Can engage MRBMs and IRBMs that other Israeli systems cannot reach | 2,500km range on cruise variant vs 500km for ballistic Iskander-M, Same TEL fires both ballistic and cruise — complicates defense, Terrain-following flight profile evades radar |
| Weaknesses | Cannot engage cruise missiles or drones (too high altitude), Limited magazine depth per launcher, Requires ~90 seconds of tracking before engagement | Subsonic — vulnerable to interception by Patriot/NASAMS/IRIS-T, Fewer missiles available than Kh-101 air-launched variants, INF Treaty violation damaged Russia's diplomatic credibility |
