Compare 2026-03-21 5 min read

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

DimensionArrow 3Iskander 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

Head-to-Head Analysis

Range & Coverage

Both Arrow-3 and Iskander-K have impressive ranges, with Arrow-3 covering 2400 km and Iskander-K reaching 2500 km. However, Arrow-3's exoatmospheric intercept capability provides a wider defensive footprint, making it a better choice for defending against ballistic missiles.
Arrow-3

Accuracy

Arrow-3's two-color infrared seeker with mid-course datalink updates from Green Pine radar provides high accuracy, while Iskander-K's INS + GLONASS + TERCOM + DSMAC + IR terminal guidance system also offers impressive accuracy. However, Arrow-3's ability to intercept in space reduces the risk of collateral damage.
Arrow-3

Cost

Both systems have similar unit costs, with Arrow-3 priced at ~$3M per interceptor and Iskander-K at ~$3M per missile. However, Arrow-3's exoatmospheric intercept capability reduces the need for multiple interceptors, making it a more cost-effective option.
Arrow-3

Guidance

Both systems have advanced guidance systems, with Arrow-3 using a two-color infrared seeker and Iskander-K employing INS + GLONASS + TERCOM + DSMAC + IR terminal guidance. However, Arrow-3's mid-course datalink updates from Green Pine radar provide additional accuracy.
Arrow-3

Warhead

Iskander-K's 480 kg conventional warhead is more powerful than Arrow-3's hit-to-kill kinetic energy warhead. However, Arrow-3's ability to intercept in space reduces the risk of collateral damage.

Scenario Analysis

Defending against Iranian ballistic missile salvo

In this scenario, Arrow-3's exoatmospheric intercept capability provides a significant advantage, allowing it to intercept ballistic missiles in space before reentry. Iskander-K's cruise missile variant can also be effective, but its subsonic speed makes it vulnerable to interception by Patriot/NASAMS/IRIS-T.
Arrow-3

Attacking high-value targets in Ukraine

In this scenario, Iskander-K's 2,500km range and terrain-following flight profile make it an effective choice for attacking high-value targets in Ukraine. Arrow-3's exoatmospheric intercept capability is less relevant in this scenario.
Iskander-K

Defending against a large-scale cruise missile attack

In this scenario, Arrow-3's ability to intercept in space provides a significant advantage, allowing it to defend against a large-scale cruise missile attack. Iskander-K's cruise missile variant can also be effective, but its subsonic speed makes it vulnerable to interception.
Arrow-3

Complementary Use

Both Arrow-3 and Iskander-K can be used in conjunction with other missile defense systems to provide a layered defense. Arrow-3's exoatmospheric intercept capability can be used to defend against ballistic missiles, while Iskander-K's cruise missile variant can be used to attack high-value targets.

Overall Verdict

Arrow-3 is the better choice for defending against ballistic missiles and providing a layered defense, while Iskander-K is the better choice for attacking high-value targets in Ukraine. Ultimately, the choice between these systems depends on the specific mission requirements and the capabilities of the defending forces.
