Overview
This comparison examines two systems from opposite ends of the missile warfare spectrum: Israel's Arrow-2, a sophisticated endoatmospheric interceptor designed to destroy ballistic missiles at altitudes up to 50 km, and Iran's Fajr-5, a cheap 333mm artillery rocket built for mass saturation attacks. These systems never directly engage each other — Arrow-2 targets ballistic missiles while Iron Dome handles rockets like the Fajr-5 — but comparing them illuminates the fundamental asymmetric cost problem dominating Middle Eastern conflict calculus. A single Arrow-2 interceptor costs 300-600 times more than one Fajr-5, yet both serve their operators' strategic objectives effectively. Understanding this cross-category dynamic is essential for defense planners assessing force structure investments, interceptor stockpile requirements, and the economic sustainability of missile defense against mass rocket arsenals numbering in the tens of thousands.

Head-to-Head Analysis
Range & Coverage
Arrow-2's 150 km intercept envelope allows it to engage incoming ballistic missiles at standoff distances, protecting broad swathes of Israeli territory from a single battery position. The system's Super Green Pine radar detects threats at ranges exceeding 500 km, providing substantial reaction time. The Fajr-5's 75 km range, while modest compared to ballistic missiles, represented a strategic threshold when first deployed — it was the first rocket in Hezbollah's arsenal capable of reaching Tel Aviv from southern Lebanon, approximately 120 km away when fired from positions north of the Litani River. From Gaza, the Fajr-5 can cover most of central and southern Israel. Both systems achieve their range objectives within their respective mission profiles.
Arrow-2 has double the range, but the Fajr-5's 75 km is specifically calibrated to threaten Israel's population centers, making both effective within their roles.
Accuracy & Guidance
Arrow-2 employs an advanced active radar seeker with mid-course command updates from the Citron Tree battle management system, achieving high probability of kill against maneuvering ballistic missile reentry vehicles. Its guidance chain integrates Green Pine radar tracking data with onboard sensors for terminal homing precision measured in meters. The Fajr-5 in its base configuration is essentially an area-effect weapon with a CEP of approximately 500 meters — adequate for terrorizing civilian populations but militarily imprecise. Some variants retrofitted with GPS guidance modules reduce CEP to roughly 50-100 meters, a significant improvement but still orders of magnitude less precise than guided munitions. The guidance gap reflects their fundamentally different purposes: precision interception versus area saturation.
Arrow-2 dominates in accuracy, but the Fajr-5 does not need precision to fulfill its terror and attrition mission against urban areas.
Cost & Economics
This is the defining dimension of the comparison and the core of the asymmetric warfare problem. Each Arrow-2 interceptor costs $2-3 million, reflecting its advanced seeker, solid-fuel booster, and aerospace-grade manufacturing. A single Fajr-5 costs $5,000-$10,000 — meaning an attacker can purchase 200-600 Fajr-5 rockets for the price of one Arrow-2. Even the Iron Dome interceptor assigned to counter Fajr-5 class threats costs approximately $50,000 per Tamir missile, creating a 5-10:1 cost disadvantage for the defender. Hezbollah's estimated 10,000+ Fajr-5 inventory represents roughly $50-100 million in investment — less than the cost of 50 Arrow-2 interceptors. This arithmetic fundamentally favors the attacker in a prolonged exchange and drives Israel toward directed-energy solutions like Iron Beam.
Fajr-5 wins the cost equation decisively — the attacker-defender cost asymmetry is the central strategic challenge for Israel's multi-layered defense architecture.
Operational Complexity
Arrow-2 requires a sophisticated operational ecosystem: the Super Green Pine phased-array radar for detection and tracking, the Citron Tree fire control center for battle management, dedicated launch vehicles, and extensively trained crews. A full Arrow-2 battery involves hundreds of personnel and weeks of deployment preparation. The entire system integrates with Israel's national command authority for engagement authorization, given the strategic implications of ABM engagement. The Fajr-5, by contrast, can be launched from a simple truck-mounted rail by a two-person crew with minimal training. Hezbollah has pre-positioned thousands of launchers in hardened bunkers across southern Lebanon, many automated for rapid sequential firing. This simplicity enables distributed, survivable deployment across hundreds of concealed locations.
Fajr-5's extreme simplicity enables mass deployment and operator survivability that Arrow-2's complex infrastructure cannot match.
Strategic Impact
Arrow-2 serves as the backbone of Israel's upper-tier missile defense, providing the critical capability to neutralize ballistic missile threats from Iran, Syria, and potentially Iraq. Without Arrow-2, Israeli cities would be defenseless against medium-range ballistic missiles carrying warheads of 500-1,000 kg. Its 2017 intercept of a Syrian SA-5 and performance during the April 2024 Iranian barrage validated decades of development. The Fajr-5's strategic impact is disproportionate to its cost — its mere existence forces Israel to maintain billion-dollar missile defense systems and drives population into shelters across the country. During conflicts, Fajr-5 barrages have disrupted Ben Gurion Airport operations, triggered nationwide economic losses estimated at $150-200 million per day, and shaped Israeli political decision-making regarding ground operations in Lebanon and Gaza.
Both deliver outsized strategic impact relative to their respective investment levels — Arrow-2 protects national survival, while Fajr-5 imposes massive costs through the threat alone.
Scenario Analysis
Mass Fajr-5 barrage against Tel Aviv from southern Lebanon
In a Hezbollah opening salvo scenario launching 200-500 Fajr-5 rockets alongside Grad and Katyusha rockets toward central Israel, Arrow-2 plays no role — this threat falls entirely within Iron Dome's engagement envelope. Arrow-2 batteries would remain on standby for the anticipated follow-on ballistic missile strikes from Iran or Hezbollah's Fateh-110 derivatives. The Fajr-5's role is to saturate Iron Dome batteries, forcing expenditure of Tamir interceptors at $50K each while threatening to overwhelm the system through sheer volume. Modeling suggests that a simultaneous salvo exceeding 50-70 rockets against a single Iron Dome battery risks leakers, particularly if combined with faster Fateh-110 variants requiring priority engagement.
Fajr-5 achieves its mission objective here — forcing massive interceptor expenditure and risking Iron Dome saturation — while Arrow-2 is simply not designed for this threat class.
Combined Iranian ballistic missile and proxy rocket attack
During the April 2024 Iranian attack, Arrow-2 and Arrow-3 engaged incoming Shahab-3 and Emad ballistic missiles at altitude while Iron Dome and David's Sling handled lower-tier threats including cruise missiles and rockets. In a future scenario combining Iranian ballistic missiles with simultaneous Hezbollah Fajr-5 barrages, Israel's layered defense must partition engagement responsibility across tiers. Arrow-2 cannot be diverted to Fajr-5 class targets without leaving the ballistic missile threat unaddressed. The Fajr-5's contribution is forcing Iron Dome batteries to deplete interceptors on cheap rockets, potentially degrading capacity to handle the more dangerous cruise missile and guided rocket threats arriving simultaneously from multiple azimuths.
Arrow-2 is the only viable option for ballistic missile defense, while Fajr-5 succeeds by consuming defender resources and complicating the multi-tier engagement picture.
Protracted 30-day attrition campaign
In a sustained conflict lasting weeks rather than days, stockpile depth becomes decisive. Israel's estimated Arrow-2 inventory of 100-200 interceptors could be exhausted within days if Iran launches successive ballistic missile salvos of 50-100 weapons. Resupply from Boeing/IAI production lines requires months. Hezbollah's Fajr-5 stockpile of 10,000+ rockets permits sustained daily barrages of 100-300 for over a month, far exceeding the approximately 3,000 Tamir interceptors Israel maintains for Iron Dome. This attrition scenario is precisely the strategic nightmare Israel's defense establishment fears — the mathematics of cheap rockets versus expensive interceptors becomes untenable over time, which is why Israel has accelerated Iron Beam laser development to achieve near-zero marginal intercept cost.
Fajr-5 wins the attrition campaign — its 100:1 stockpile advantage and 300:1 cost advantage make it the defining weapon in any protracted exchange scenario.
Complementary Use
These systems never operate in the same force — they serve opposing sides. However, they are deeply complementary from the attacker's perspective within a coordinated multi-axis assault. Iran's strategy explicitly pairs ballistic missile salvos (forcing Arrow-2/3 engagement) with simultaneous proxy rocket barrages using Fajr-5 class weapons (saturating Iron Dome). This forces Israel to simultaneously defend across all defense tiers, preventing reallocation of lower-tier interceptors to assist upper tiers and vice versa. The Fajr-5 achieves maximum strategic value precisely when Arrow-2 is already engaged, because Israel cannot deprioritize either threat class. This coordinated pressure across defense layers is the operational concept behind Iran's "ring of fire" strategy using Hezbollah, Hamas, and other proxies as simultaneous rocket artillery platforms.
Overall Verdict
Comparing Arrow-2 to Fajr-5 is comparing a precision scalpel to a sledgehammer — both are effective tools for fundamentally different jobs. Arrow-2 represents the pinnacle of missile defense engineering: a Mach 9 interceptor with active radar guidance capable of destroying ballistic missiles at 50 km altitude, protecting millions of civilians from catastrophic warheads. It is irreplaceable in Israel's defense architecture and has proven its worth operationally. The Fajr-5, despite being unguided, cheap, and inaccurate, may actually be the more strategically significant weapon in the current conflict calculus. At $5,000-$10,000 per round versus $50,000 per Iron Dome interceptor, it imposes an unsustainable cost ratio on the defender. Hezbollah's 10,000+ Fajr-5 stockpile represents a $50-100 million investment that forces Israel to maintain a $10+ billion multi-layered defense architecture. This asymmetry — where the cheapest weapon drives the most expensive countermeasure — is the defining challenge of modern Middle Eastern conflict and the reason directed-energy weapons like Iron Beam represent not a luxury but an existential necessity for Israeli defense sustainability.
Frequently Asked Questions
Can Arrow-2 intercept Fajr-5 rockets?
Arrow-2 is technically capable of engaging any airborne target within its envelope, but it would never be tasked against Fajr-5 rockets. Using a $2-3 million Arrow-2 interceptor against a $5,000 rocket would be an absurd misallocation of resources. Iron Dome's Tamir interceptor, at approximately $50,000 per round, is the designated system for Fajr-5 class threats. Arrow-2 is reserved exclusively for ballistic missile threats that lower-tier systems cannot handle.
How many Fajr-5 rockets does Hezbollah have?
Pre-2024 estimates placed Hezbollah's Fajr-5 stockpile at over 10,000 rockets, as part of a total arsenal exceeding 150,000 rockets and missiles of various types. This inventory was supplied primarily through Iran's IRGC logistics network via Syria. Israeli military operations in 2024-2025 significantly degraded but did not eliminate these stockpiles, and Iran has continued resupply efforts through surviving corridors.
What is the cost-exchange ratio between Arrow-2 and Fajr-5?
The Arrow-2 to Fajr-5 cost ratio is approximately 300-600:1, meaning one Arrow-2 interceptor costs as much as 300-600 Fajr-5 rockets. However, these systems never directly engage each other. The more relevant cost-exchange is Iron Dome vs Fajr-5, which stands at roughly 5-10:1 in the attacker's favor — still heavily advantaging the rocket over the interceptor in economic terms.
Has Arrow-2 been used in combat?
Yes. Arrow-2 achieved its first confirmed operational intercept in March 2017, destroying a Syrian SA-5 surface-to-air missile that had overflown its target and was heading toward Israeli territory. During Iran's April 2024 direct attack on Israel, Arrow-2 interceptors were used alongside Arrow-3 to engage incoming Shahab-3 and Emad ballistic missiles, contributing to the near-total intercept rate achieved that night.
Why doesn't Israel just destroy Fajr-5 stockpiles before they launch?
Hezbollah has dispersed its Fajr-5 arsenal across thousands of concealed positions in southern Lebanon, including purpose-built underground bunkers, residential buildings, and mobile launchers. Pre-emptive destruction of the entire stockpile would require sustained air operations across hundreds of square kilometers of densely populated terrain. Israel's 2006 Lebanon War demonstrated the difficulty — despite 34 days of intensive air strikes, significant rocket capacity survived and continued firing until the ceasefire.
