Overview
The Arrow-2 and Raad-500 represent opposite sides of the offense-defense equation in Middle Eastern missile warfare. Arrow-2, Israel's endoatmospheric interceptor operational since 2000, was purpose-built to destroy incoming theater ballistic missiles during their terminal descent phase. The Raad-500, Iran's composite-casing solid-fuel missile fielded in 2020, was explicitly designed to defeat interceptors like Arrow-2 through maneuvering reentry vehicle technology. This comparison illuminates one of modern warfare's most consequential matchups: can a 25-year-old intercept architecture neutralize a missile engineered specifically to evade it? The Raad-500's lighter composite motor casing and MaRV capability represent Iran's technological pivot toward penetration aids, while Arrow-2's fragmentation warhead and Super Green Pine radar represent decades of iterative refinement against evolving threats. For defense planners, the interaction between these two systems defines whether Israel's layered defense architecture holds or requires costly upgrades to maintain its edge against Iran's next-generation strike capabilities.

Head-to-Head Analysis
Speed & Kinematic Performance
Arrow-2 reaches Mach 9, more than twice the Raad-500's Mach 4 terminal velocity. This speed advantage is fundamental to the interceptor's mission: it must close on a target that is itself moving at hypersonic speeds during reentry. Arrow-2's velocity allows it to maneuver aggressively during the endgame, adjusting its trajectory to align its directional fragmentation warhead with the incoming threat. The Raad-500's Mach 4 speed is respectable for a short-range ballistic missile but notably slower than Iran's longer-range systems like the Emad or Sejjil. However, the Raad-500 compensates with its MaRV capability, which introduces lateral maneuvers during reentry that can stress an interceptor's tracking solution regardless of raw speed differential.
Arrow-2 dominates in raw kinematic performance, which is essential for its intercept mission, though the Raad-500's MaRV partially offsets this advantage.
Guidance & Terminal Accuracy
Arrow-2 uses an active radar seeker that homes on the incoming missile's radar signature during terminal phase, guided initially by the Super Green Pine phased-array radar that can track targets at ranges exceeding 500 km. This two-stage guidance architecture provides robust tracking even against clutter and countermeasures. The Raad-500 employs INS with GPS correction and a maneuvering reentry vehicle, giving it a claimed CEP of approximately 30-50 meters. The MaRV component is the critical differentiator: by executing programmed or sensor-driven maneuvers during reentry, the Raad-500 attempts to present a non-ballistic trajectory that degrades the interceptor's prediction algorithms. Whether Iran has truly operationalized reliable MaRV guidance remains debated among Western analysts.
Arrow-2's active radar seeker is proven and refined over decades; the Raad-500's MaRV guidance is innovative but unproven in combat.
Cost & Economic Sustainability
At $2-3 million per interceptor versus $400,000 per Raad-500, the cost exchange ratio heavily favors the attacker. Israel must expend 5-7× more per engagement than Iran spends per shot, and standard doctrine calls for firing two interceptors per incoming missile, pushing the ratio to 10-15×. Over a sustained campaign involving hundreds of missiles, this asymmetry becomes strategically significant. Iran can produce Raad-500s using relatively simple composite manufacturing and solid-fuel propellant, while Arrow-2 interceptors require precision radar seekers and complex integration. Israel's interceptor production rate is classified but estimated at 50-100 per year, meaning a salvo of even 50 Raad-500s could consume months of Arrow-2 production in minutes.
Raad-500 holds a decisive cost advantage that creates strategic pressure on Israel's interceptor inventories over any sustained conflict.
Operational Flexibility
Arrow-2 is a fixed-architecture system deployed at known battery positions in central Israel, linked to the Super Green Pine radar and the Elta EL/M-2080 battle management system. It requires significant infrastructure and cannot be rapidly relocated. The Raad-500, as a solid-fueled TEL-launched missile, offers Iran substantial operational flexibility: it can be dispersed across Iran's road network, launched from tunnels or hardened shelters, and repositioned between salvos. This mobile-versus-fixed dynamic gives the Raad-500 a survivability advantage in a prolonged conflict, while Arrow-2 batteries become known targets themselves. However, Arrow-2 benefits from integration into Israel's multi-layered defense network, receiving early warning from satellites and allied radar systems.
Raad-500's TEL mobility and dispersal capability provide superior operational flexibility compared to Arrow-2's fixed-site architecture.
Combat Proven Reliability
Arrow-2 has a verified combat record. Its 2017 intercept of a Syrian SA-5 missile was the first operational use of any Arrow variant, and during Iran's April 2024 mass attack involving over 300 projectiles, Arrow-2 worked alongside Arrow-3 to successfully neutralize ballistic missile threats. These real-world engagements validated decades of testing and provided invaluable operational data. The Raad-500 has never been used in combat. Its MaRV capability, composite casing, and overall reliability remain theoretical claims from IRGC Aerospace Force promotional materials. Iran's broader missile program has a mixed combat record: the January 2020 Al-Asad strikes demonstrated accuracy, while the April 2024 attack saw most missiles intercepted. Without combat data, the Raad-500's advertised capabilities carry inherent uncertainty.
Arrow-2's proven combat record provides a significant confidence advantage over the Raad-500's untested claims.
Scenario Analysis
Iran launches a 30-missile salvo of mixed Raad-500 and Fateh-110 variants against Israeli military targets
In a mixed salvo, Arrow-2 would be tasked against the ballistic threats penetrating the upper atmosphere while David's Sling handles lower-tier missiles. The Raad-500's MaRV capability would stress Arrow-2's tracking algorithms more than the non-maneuvering Fateh-110. If even 3-5 Raad-500s execute effective terminal maneuvers, Arrow-2 would need to allocate additional interceptors per target, potentially exhausting a battery's ready magazine of approximately 6-8 missiles before all threats are neutralized. At $2.5M per interceptor versus $400K per Raad-500, Israel would spend roughly $60-80M defending against a $12M attack. The engagement is winnable but economically punishing.
Arrow-2 (system_a) — it remains the only viable defense against incoming ballistic missiles regardless of cost, but the Raad-500's MaRV capability degrades intercept efficiency.
Iran attempts a precision strike on Nevatim Air Base using Raad-500s to destroy F-35I shelters
Nevatim Air Base sits within Arrow-2's defensive umbrella in southern Israel. A targeted strike using 10-15 Raad-500s would test whether MaRV-equipped missiles can penetrate layered defense. Arrow-2 would engage at 40-80 km altitude during terminal phase, with approximately 10-15 seconds of tracking time against a maneuvering target. Even if Arrow-2 achieves its estimated 80-90% kill probability against conventional ballistic missiles, the MaRV could reduce this to 60-70%, allowing 3-6 missiles to leak through against a 15-missile salvo. David's Sling and Patriot PAC-3 would serve as backup layers. The Raad-500's 500 km range means launch points in western Iran are within reach, complicating pre-launch suppression.
Raad-500 (system_b) — the attacker's advantage: even partial penetration of a 15-missile MaRV-equipped salvo could achieve mission objectives against high-value fixed targets.
Sustained 30-day conflict with Iran launching 5-10 Raad-500s daily alongside cruise missiles and drones
A sustained campaign reveals the cost-exchange problem at scale. Over 30 days, Iran could launch 150-300 Raad-500s at a cost of $60-120M. Defending with Arrow-2 (two interceptors per threat) would require 300-600 interceptors costing $750M-$1.8B — likely exceeding Israel's total Arrow-2 inventory. Israel would be forced to prioritize which targets receive Arrow-2 coverage, leaving some areas defended only by David's Sling or Patriot. Iran's ability to sustain production of relatively simple solid-fuel composite missiles outpaces Israel's interceptor manufacturing. The simultaneous cruise missile and drone threats would further strain the integrated air defense network by forcing resource allocation across multiple threat tiers.
Raad-500 (system_b) — in a war of attrition, the cheaper offensive missile exhausts the expensive interceptor inventory, a fundamental challenge for all missile defense architectures.
Complementary Use
These systems are adversarial by design: the Raad-500 exists to penetrate defenses like Arrow-2, while Arrow-2 exists to destroy missiles like the Raad-500. However, understanding their interaction reveals how both sides can optimize force structure. For Israel, integrating Arrow-2 with Arrow-3 (exoatmospheric) and David's Sling (lower tier) creates layered redundancy that forces Iran to design penetration aids against multiple intercept geometries simultaneously. For Iran, pairing Raad-500 MaRV missiles with conventional Fateh-110 variants and cruise missile diversions creates a complex targeting problem that no single interceptor type can optimally address. The offense-defense dynamic between these specific systems drives both nations' procurement and R&D priorities.
Overall Verdict
Arrow-2 and Raad-500 embody the fundamental offense-defense asymmetry that defines modern missile warfare. Arrow-2 is the superior system in terms of proven technology, combat reliability, and sheer kinematic performance — it has successfully defended Israel against real ballistic missile threats and remains a cornerstone of the world's most sophisticated layered defense architecture. However, the Raad-500 represents exactly the kind of threat that challenges Arrow-2's long-term viability: cheap enough to be launched in large salvos, advanced enough with MaRV to degrade intercept probability, and produced at a fraction of the interceptor's cost. For Israel, the answer is not whether Arrow-2 can defeat the Raad-500 — it can, in most individual engagements — but whether the economics of interception remain sustainable against an adversary that can produce offensive missiles at 5-7× lower cost. This is why Israel is investing in Iron Beam directed-energy weapons to collapse the cost-exchange ratio. For Iran, the Raad-500 validates the strategic logic of composite-casing MaRV-equipped missiles as the most cost-effective path to threatening Israeli strategic targets despite formidable defenses.
Frequently Asked Questions
Can Arrow-2 intercept the Raad-500 missile?
Yes, Arrow-2 is designed to intercept theater ballistic missiles in the Raad-500's class. However, the Raad-500's maneuvering reentry vehicle (MaRV) capability is specifically intended to complicate intercept solutions. While Arrow-2's active radar seeker and Mach 9 speed give it a kinematic advantage, the MaRV may reduce single-shot kill probability from an estimated 80-90% to 60-70%.
How much does it cost to shoot down a Raad-500 with Arrow-2?
Each Arrow-2 interceptor costs approximately $2-3 million, and standard doctrine calls for firing two interceptors per incoming ballistic missile. Defending against a single $400,000 Raad-500 therefore costs $4-6 million, creating a 10-15× cost disadvantage for the defender. Over a sustained campaign, this ratio threatens interceptor stockpile exhaustion.
What is a MaRV and how does it affect missile defense?
A Maneuvering Reentry Vehicle (MaRV) can change course during its terminal descent phase, unlike conventional ballistic warheads that follow a predictable arc. This forces interceptors to continuously update their targeting solution rather than predicting the impact point early. Iran claims the Raad-500 has MaRV capability, though its effectiveness against modern interceptors like Arrow-2 remains unproven in combat.
Why does the Raad-500 use composite casing?
Composite motor casings are significantly lighter than traditional steel, reducing the missile's overall weight by approximately 30%. This weight savings translates to greater range, higher terminal velocity, or increased payload — or some combination. The Raad-500 was Iran's first missile to use this technology, signaling a shift toward more advanced manufacturing capabilities within the IRGC Aerospace program.
Is Arrow-2 being replaced by Arrow-3?
Arrow-3 supplements rather than replaces Arrow-2. Arrow-3 intercepts targets in space (exoatmospheric) during midcourse flight, while Arrow-2 engages targets during atmospheric reentry (endoatmospheric). Together they provide layered defense: Arrow-3 takes the first shot at high altitude, and Arrow-2 serves as the backup if Arrow-3 misses. Both remain in active Israeli service.
