Overview
Comparing the Arrow-2 interceptor with the F-15EX Eagle II juxtaposes two fundamentally different philosophies of air and missile defense. Arrow-2 is a dedicated endoatmospheric interceptor — a single-purpose weapon designed to destroy incoming ballistic missiles during their terminal descent at Mach 9. The F-15EX is a multi-role strike fighter capable of carrying 29,000 lbs of ordnance, functioning as an airborne missile truck that can prosecute air-to-air, air-to-ground, and potentially even boost-phase intercept missions. This cross-category comparison matters because modern theater defense architectures increasingly integrate both dedicated interceptors and multi-role fighters into layered kill chains. The April 2024 Iranian attack on Israel demonstrated that successful defense requires Arrow interceptors working alongside fighter aircraft conducting combat air patrols. Understanding where each platform fits — and where their capabilities overlap or complement — is essential for defense planners allocating finite budgets across offensive and defensive capabilities in an era of rapidly expanding missile threats.

Head-to-Head Analysis
Mission Scope & Versatility
Arrow-2 excels at exactly one mission: destroying incoming ballistic missiles during their terminal phase within the atmosphere. It cannot be repurposed for air-to-air combat, ground attack, or reconnaissance. The F-15EX, by contrast, is designed as the most versatile fighter in the US inventory. It can carry 12 air-to-air missiles simultaneously — triple the F-35's internal capacity — while also delivering JDAMs, SDB IIs, JASSM-ERs, and potentially hypersonic weapons. Its Open Mission Systems architecture allows rapid integration of new weapons and sensors. For a defense planner choosing between the two, Arrow-2 provides irreplaceable ballistic missile defense capability that no fighter can replicate, while the F-15EX offers mission flexibility across the entire spectrum of air operations. Neither can substitute for the other.
F-15EX wins on versatility — it covers air superiority, deep strike, and standoff attack missions that Arrow-2 simply cannot perform.
Cost & Affordability
At $2-3 million per interceptor, Arrow-2 appears dramatically cheaper than the $87.7 million F-15EX. But this comparison is misleading without context. A single Arrow-2 battery — including the Super Green Pine radar, Citron Tree battle management center, and launcher vehicles — costs hundreds of millions. Israel operates limited batteries that collectively represent multi-billion dollar investments. Meanwhile, an F-15EX can fly thousands of sorties over its 20,000-hour airframe life, amortizing its cost across decades of operations. The cost-per-engagement calculation also differs: Arrow-2 expends a $3 million round to destroy a $500,000 Shahab-3, while the F-15EX's AIM-120D costs roughly $1.1 million but is engaging aircraft worth tens of millions. Each platform's economics make sense within its operational domain.
Arrow-2 wins on per-shot cost, but total system economics favor the F-15EX's reusability over decades of multi-mission operations.
Threat Response Speed
Arrow-2 operates within an automated battle management system where the Super Green Pine radar detects a ballistic missile launch at ranges exceeding 500 km, tracks the trajectory, and cues an interceptor launch within seconds. Human operators confirm the engagement but the system's reaction timeline is measured in single-digit seconds from detection to launch. The F-15EX, even when holding on combat air patrol, requires minutes to vector toward a threat, achieve weapons parameters, and employ ordnance. If scrambled from alert, response time extends to 10-15 minutes. Against ballistic missiles with 5-8 minute flight times from Iran to Israel, only dedicated interceptors like Arrow-2 can react fast enough. The F-15EX's speed advantage lies in sustained presence — a CAP station can maintain coverage for hours.
Arrow-2 wins decisively — its automated seconds-to-launch response is the only viable counter to ballistic missile threats with minimal warning time.
Survivability & Persistence
Arrow-2 launchers are fixed or semi-mobile ground installations that can be targeted by enemy reconnaissance and precision strikes. Their Super Green Pine radars emit powerful signatures detectable by electronic intelligence. Once an Arrow-2 battery's interceptors are expended, it requires hours to reload. The F-15EX, while not stealthy with a significant radar cross-section, benefits from mobility — it can reposition at Mach 2.5, use terrain masking, and receive targeting data via Link 16 from stealthy platforms like the F-35. Its 20,000-hour airframe life and twin F110-GE-129 engines provide exceptional structural resilience. The F-15EX can also operate from dispersed bases, complicating enemy targeting. However, against peer adversaries with advanced SAMs, its lack of stealth becomes a critical vulnerability requiring standoff tactics.
F-15EX wins on survivability through mobility and dispersal, though Arrow-2's hardened sites and decoys partially offset its static nature.
Integration in Layered Defense
Both systems are designed to operate within larger defense architectures rather than independently. Arrow-2 forms the upper-atmospheric tier of Israel's four-layer shield — above Iron Dome and David's Sling, working alongside Arrow-3 for exoatmospheric threats. Its Citron Tree battle management system integrates with US AN/TPY-2 radar data and Aegis BMD via Link 16. The F-15EX is designed as the high-capacity complement to the F-35 in USAF's force mix — the F-35 penetrates contested airspace and shares targeting data while the F-15EX stands off and launches salvos of long-range weapons. During the April 2024 Iranian attack, US F-15Es and Navy F/A-18s shot down Iranian drones and cruise missiles while Arrow interceptors handled ballistic threats. This real-world example demonstrates the complementary nature of fighters and dedicated interceptors.
Tie — both systems are architecturally designed as components of larger kill chains and neither functions optimally in isolation.
Scenario Analysis
Iranian ballistic missile salvo targeting Israeli air bases
In a repeat of the April 2024 scenario where Iran launched 120+ ballistic missiles at Israel, Arrow-2 is the only viable defense. Its Mach 9 speed and automated engagement sequence can prosecute multiple incoming Shahab-3, Emad, and Ghadr-110 missiles during their terminal phase. The Super Green Pine radar can track 14 targets simultaneously and cue sequential intercepts. The F-15EX cannot intercept ballistic missiles in terminal flight — even its AIM-120D lacks the kinematic envelope for Mach 10+ reentry vehicles. However, F-15EX aircraft would contribute by intercepting slower cruise missiles and drones in the same salvo, as US fighters did in April 2024 when they downed over 70 Iranian one-way attack drones approaching from Iraq and Jordan.
Arrow-2 — it is the only system capable of engaging ballistic missiles in their terminal phase. F-15EX cannot substitute for dedicated BMD interceptors against this threat class.
Suppression of enemy air defenses (SEAD) against Iranian S-300 network
Degrading Iran's integrated air defense system — anchored by S-300PMU2 batteries at nuclear sites — requires penetrating strike aircraft with electronic warfare capabilities and standoff precision weapons. The F-15EX can carry AGM-88G AARGM-ER anti-radiation missiles, JASSM-ERs for standoff strike, and GBU-39 SDBs for target saturation. Its APG-82 AESA radar provides electronic attack modes. Operating behind F-35s that identify and geolocate SAM radars, F-15EXs can launch massed standoff strikes from outside the S-300's engagement envelope. Arrow-2 has zero utility in this scenario — it is a defensive interceptor with no air-to-ground capability. SEAD missions require the offensive reach, payload capacity, and sensor integration that only multi-role fighters provide.
F-15EX — SEAD requires offensive strike capability, massive payload capacity, and sensor fusion that Arrow-2 cannot provide by design.
Sustained multi-week conflict with daily missile and drone attacks
A prolonged conflict exposes critical sustainability differences. Arrow-2 interceptor stocks are finite — Israel reportedly maintains hundreds of rounds, but at $2-3 million each and with production timelines measured in months, attrition becomes a strategic concern. During a multi-week campaign with daily salvos, Arrow-2 depletion risk is real, as Israel's October 2024 interceptor expenditure demonstrated. The F-15EX's advantage in sustained operations is its reusability — the same aircraft flies multiple sorties daily, can be rearmed in under an hour, and its AIM-120D missiles are produced at higher rates than Arrow-2 interceptors. F-15EXs can also shift missions — flying SEAD one day, combat air patrol the next, and deep strike the following day. Both systems face munitions sustainability challenges, but the F-15EX's versatility provides more options for force management.
F-15EX — its reusability, multi-mission flexibility, and higher munition production rates provide superior sustainability in extended campaigns.
Complementary Use
Arrow-2 and F-15EX are not competitors but essential partners in a comprehensive theater defense architecture. The April 2024 Iranian attack proved this concept operationally: Arrow-2 and Arrow-3 intercepted ballistic missiles in their terminal and midcourse phases while US and Israeli fighters — including F-15s — shot down cruise missiles and drones at longer ranges. In a mature kill chain, F-15EX aircraft flying combat air patrol provide a forward defensive layer against air-breathing threats, while Arrow-2 batteries handle the ballistic missiles that fighters cannot engage. The F-15EX's APG-82 radar can also provide early tracking data to Arrow battle management systems via Link 16. Looking forward, the F-15EX's designation as a hypersonic weapons carrier could add an offensive dimension — striking enemy launch sites while Arrow-2 defends against missiles already in flight.
Overall Verdict
Arrow-2 and F-15EX represent fundamentally different answers to fundamentally different threats, making direct comparison less about which is 'better' and more about understanding where each is indispensable. For ballistic missile defense, Arrow-2 has no substitute — its Mach 9 speed, automated engagement, and proven combat record against Iranian missiles make it the only viable terminal-phase interceptor in this comparison. No fighter aircraft, regardless of capability, can replicate this mission. For offensive operations, persistent air defense, SEAD, deep strike, and sustained multi-week campaigns, the F-15EX provides capabilities that Arrow-2 was never designed to deliver. Its 29,000 lb payload, 12-missile air-to-air capacity, and reusable airframe offer strategic flexibility that a single-use interceptor cannot match. The critical insight for defense planners is that these systems are not substitutes but complements. Israel's April 2024 defense succeeded precisely because interceptors and fighters operated in concert. Any force structure that invests in one at the expense of the other creates exploitable gaps. The optimal allocation depends on the specific threat environment: nations facing primarily ballistic missile threats should prioritize Arrow-class interceptors, while those requiring power projection need F-15EX-class fighters. Most will need both.
Frequently Asked Questions
Can the F-15EX shoot down ballistic missiles?
The F-15EX cannot intercept ballistic missiles in their terminal phase — its AIM-120D air-to-air missiles lack the kinematic energy to engage reentry vehicles traveling at Mach 10+. However, the USAF has studied using F-15EX as a platform for boost-phase intercept concepts, where missiles are targeted shortly after launch while still relatively slow. Currently, only dedicated systems like Arrow-2, THAAD, and Patriot PAC-3 can engage ballistic missiles.
How many Arrow-2 interceptors does Israel have?
Israel does not publicly disclose its Arrow-2 interceptor stockpile. Open-source estimates suggest Israel maintains several hundred interceptors across multiple batteries. The Arrow-2 system is co-produced by Israel Aerospace Industries and Boeing, with US foreign military financing supporting procurement. Interceptor production rates are limited, making stockpile management a critical strategic concern during sustained conflicts.
Why does the US need F-15EX if it has F-35?
The F-15EX complements the F-35 rather than replacing it. The F-35 provides stealth penetration and sensor fusion but carries only 4 air-to-air missiles internally. The F-15EX carries 12 AIM-120Ds — serving as a 'missile truck' that receives targeting data from F-35s via Link 16 and launches massed volleys from standoff range. The F-15EX also carries heavier payloads including hypersonic weapons that won't fit in the F-35's internal bays.
What is the difference between Arrow-2 and Arrow-3?
Arrow-2 intercepts ballistic missiles inside the atmosphere (endoatmospheric) at altitudes up to 50 km using a fragmentation warhead. Arrow-3 intercepts outside the atmosphere (exoatmospheric) at altitudes above 100 km using hit-to-kill technology. Arrow-3 engages threats earlier in flight and produces no debris over defended territory, while Arrow-2 serves as a backup layer if Arrow-3 misses, providing redundancy in Israel's defense architecture.
How much does an Arrow-2 interceptor cost compared to an F-15EX missile?
An Arrow-2 interceptor costs approximately $2-3 million per round. The F-15EX's primary air-to-air weapon, the AIM-120D AMRAAM, costs roughly $1.1 million per missile. However, this comparison is incomplete: the Arrow-2 engages ballistic missiles worth $1-10 million each, while the AIM-120D targets aircraft worth $30-100+ million. The cost-exchange ratio favors both systems within their respective mission sets.
