Overview
Comparing an interceptor missile with a strike fighter seems like comparing apples and oranges, but this cross-category analysis addresses a fundamental strategic question: is it more effective to shoot down ballistic missiles in flight or destroy the launchers before they fire? Arrow-2 represents Israel's shield — the endoatmospheric layer of its multi-tier missile defense architecture, designed to intercept theater ballistic missiles like the Shahab-3 during their terminal descent. The F-15E Strike Eagle, particularly in its Israeli F-15I Ra'am configuration, represents the sword — the deep-strike platform capable of reaching Iranian launch sites, missile production facilities, and TEL staging areas. During Iran's April 2024 missile barrage, Arrow-2 and Arrow-3 intercepted incoming threats, but the same scenario raised urgent questions about whether preemptive strikes on launch infrastructure using F-15 platforms would have been more cost-effective. This comparison examines the defensive-interceptor-versus-offensive-striker calculus that defense planners in Israel, the United States, and Saudi Arabia must weigh when allocating finite budgets between active missile defense and deep-strike capability.

Head-to-Head Analysis
Cost-Effectiveness
At $2–3 million per Arrow-2 interceptor versus $100 million per F-15E airframe, the cost calculus is nuanced. An Arrow-2 is consumed with each engagement, while an F-15E flies thousands of sorties over its 30+ year service life. Against a single incoming Shahab-3 (estimated $5M), Arrow-2 provides a favorable cost-exchange ratio. But against a salvo of 100+ missiles, interceptor expenditure escalates rapidly — potentially $200–300M in one engagement. An F-15E sortie carrying eight JDAMs ($25K each) can destroy multiple TELs and their missiles before launch, potentially neutralizing dozens of threats for $200K in munitions plus $30K in flight costs. However, the F-15E requires SEAD support, tanker aircraft, and intelligence preparation that dramatically increase total mission cost. The comparison ultimately depends on whether you are absorbing an attack or preventing one.
F-15E offers better long-term cost efficiency as a reusable platform, but Arrow-2 provides irreplaceable immediate cost-exchange against incoming missiles.
Threat Neutralization Approach
Arrow-2 operates right-of-launch, intercepting ballistic missiles during their terminal descent at altitudes of 10–50 km within the atmosphere. Its fragmentation warhead destroys or disables the incoming threat, but the engagement occurs over defended territory — debris falls on the area being protected. The F-15E operates left-of-launch, striking missile infrastructure, TELs, and command nodes before missiles are fired. This eliminates threats at source but requires actionable intelligence on mobile launcher locations, which are notoriously difficult to track. During the 1991 Gulf War, coalition aircraft flew thousands of Scud-hunting sorties with minimal success against mobile TELs. Modern ISR capabilities from satellites and drones have improved targeting, but the fundamental challenge of hitting mobile launchers in contested airspace persists. Arrow-2's advantage is certainty — it engages known threats. The F-15E's advantage is leverage — one successful strike can eliminate multiple unfired missiles.
Arrow-2 provides guaranteed engagement of detected threats; F-15E offers higher leverage but depends on intelligence quality and airspace access.
Operational Flexibility
The F-15E vastly outperforms Arrow-2 in flexibility. While Arrow-2 serves exactly one purpose — intercepting ballistic missiles — the F-15E is a genuine multi-role platform capable of deep interdiction, close air support, air superiority, maritime strike, and SEAD/DEAD missions. Israeli F-15I Ra'am aircraft conduct routine strikes against Iranian weapons shipments in Syria while maintaining readiness for potential deep-strike missions against Iran's nuclear facilities. Saudi F-15SA aircraft simultaneously prosecute targets in Yemen and maintain air defense patrols. Arrow-2, by contrast, sits in its canister awaiting a specific threat category. It cannot engage aircraft, cruise missiles, or drones — those threats require separate systems like David's Sling and Iron Dome. For nations with limited defense budgets, the F-15E's versatility offers significantly more capability per dollar across the full spectrum of conflict, from counterinsurgency to peer-state warfare.
F-15E dominates in flexibility — it performs a dozen mission types while Arrow-2 performs exactly one.
Survivability & Risk
Arrow-2 operates from fixed, known launch sites — the Super Green Pine radar and launch batteries are high-value targets that adversaries actively plan to strike. However, the system places no human operators in physical danger during engagements, as crews remain at hardened ground stations while the interceptor flies autonomously after launch. The F-15E places two aircrew members in direct physical danger during every sortie. Against Iran's integrated air defense network — comprising S-300PMU2, Bavar-373, and dozens of SAM systems — an F-15E strike package faces significant attrition risk. The aircraft's large radar cross-section (~10 m²) makes it detectable at long range, requiring extensive SEAD support and electronic warfare coverage. A single F-15E loss represents $100M in hardware plus irreplaceable experienced aircrew. Arrow-2 interceptor losses are expected and budgeted — consumption is its designed purpose. This risk asymmetry heavily favors the defensive approach for homeland protection.
Arrow-2 involves zero aircrew risk and expected interceptor consumption; F-15E sorties risk irreplaceable crews and expensive airframes.
Scalability & Sustainment
Scaling Arrow-2 defense requires purchasing more interceptors and launchers at a linear cost, constrained by IAI/Boeing production capacity of roughly 100–150 interceptors per year. Against Iran's estimated 3,000+ ballistic missiles, Israel would need thousands of interceptors at $2–3M each, creating a potential multi-billion-dollar sustainment burden. F-15E sustainability benefits from established global supply chains — Boeing has delivered over 500 F-15E variants, with the F-15EX production line now active. However, replacing combat losses takes years. The critical bottleneck for each system differs: Arrow-2 faces interceptor inventory exhaustion during sustained salvo attacks, while F-15E operations face aircrew fatigue, maintenance cycles, and aerial refueling constraints. In a prolonged conflict, the F-15E fleet can regenerate sorties daily while Arrow-2 batteries may deplete their ready inventory within hours of sustained salvos.
F-15E provides better sustainment in prolonged conflict through sortie regeneration, but Arrow-2 scales more predictably for known threat volumes.
Scenario Analysis
Iranian ballistic missile salvo against Israeli cities
In a scenario mirroring Iran's April 2024 attack — 120+ ballistic missiles launched in a coordinated salvo — Arrow-2 is the only viable immediate response. No F-15E sortie can reach Iranian launch sites in time to prevent missiles already in flight. Arrow-2 batteries, cued by Green Pine radar and Elta EL/M-2080 sensors, begin engaging targets within minutes of launch detection. During the 2024 attack, Arrow interceptors achieved near-perfect success rates against ballistic threats. The F-15E's contribution in this scenario is limited to post-attack retaliatory strikes against launch sites and reload infrastructure. However, if intelligence indicated an imminent attack 24–48 hours in advance, preemptive F-15E strikes against TEL staging areas could have reduced the salvo size — though this requires political authorization rarely granted for preemptive action.
Arrow-2 — it is the only system that can defeat missiles already in flight. In a defensive emergency, there is no substitute for active missile defense.
Preemptive strike on Iranian missile and nuclear infrastructure
If Israel or the US decides to strike Iran's missile production facilities, TEL garrisons, and nuclear infrastructure, the F-15E becomes essential while Arrow-2 is irrelevant to the offensive mission. Israeli F-15I Ra'am aircraft represent the only IAF platform with sufficient combat radius — approximately 1,750 km with conformal fuel tanks — to reach targets deep inside Iran. A strike package of 25–30 F-15I aircraft armed with GBU-28 bunker busters and GBU-31 JDAMs could target hardened facilities at Parchin, Khojir, and known missile production sites. Arrow-2 would provide defensive coverage for Israeli territory during the expected Iranian retaliatory response but plays no role in the strike itself. The mission's success depends entirely on the F-15E's ability to penetrate Iranian airspace, deliver ordnance accurately, and return — requiring substantial enabling force packages including tankers, EW aircraft, and SEAD escorts.
F-15E Strike Eagle — offensive deep strike is the F-15E's defining mission, and no interceptor missile can substitute for the ability to destroy threats at their source.
Multi-week attrition conflict with sustained Iranian missile salvos
In a sustained conflict lasting weeks — similar to the current Coalition vs Iran Axis scenario — both systems face critical sustainability challenges but serve fundamentally different roles. Arrow-2 interceptor inventories, estimated at 100–200 ready rounds, could be exhausted within days against sustained Iranian salvos of 20–50 missiles per day. Resupply requires months of production lead time. F-15E fleets, while losing aircraft to attrition, can sustain daily sortie generation — each aircraft typically flies 1–2 combat missions per day. Over weeks, F-15E strikes systematically degrade Iran's missile production capability, reducing the salvo volume that Arrow-2 must counter. This creates a positive feedback loop: effective strikes reduce interceptor consumption. The optimal strategy integrates both — Arrow-2 defends against immediate threats while F-15E strikes reduce the future threat pipeline. Neither system alone provides an adequate solution to prolonged conflict.
F-15E Strike Eagle — in sustained conflict, offensive capability that degrades the enemy's launch infrastructure becomes more valuable than purely defensive interception facing inventory exhaustion.
Complementary Use
Arrow-2 and F-15E are not competitors — they are complementary halves of a complete counter-missile strategy. Israel's doctrine explicitly integrates both: Arrow-2 and Arrow-3 provide the defensive shield that absorbs incoming salvos while F-15I Ra'am aircraft execute offensive counter-force strikes against launch sites and missile infrastructure. This sword-and-shield approach was demonstrated during the April 2024 Iranian attack, where Arrow systems intercepted incoming missiles while Israeli strike aircraft prepared retaliatory missions. The F-15E reduces future threat volume by destroying launchers, production facilities, and supply lines, directly easing the burden on Arrow-2's finite interceptor inventory. Conversely, Arrow-2 provides the time and protection that allows F-15E strike operations to proceed without catastrophic homeland damage. Effective defense against a state-level ballistic missile threat requires both active interception and offensive counter-force capability operating simultaneously and continuously.
Overall Verdict
This comparison reveals why modern defense strategy rejects the false choice between offense and defense. Arrow-2 and the F-15E address the ballistic missile threat at fundamentally different points in the kill chain, and both are indispensable. Arrow-2 excels in its narrow but critical role — intercepting incoming ballistic missiles with high probability of kill and providing immediate homeland protection that no strike aircraft can deliver. The F-15E excels across a vastly broader mission set, offering strategic reach, operational flexibility, and the ability to eliminate threats at their source before they become Arrow-2's problem. For a defense planner forced to choose, the answer depends on strategic context: a nation under active missile attack needs Arrow-2 immediately and urgently; a nation seeking to prevent future attacks or degrade an adversary's missile capability needs the F-15E's deep-strike capacity. Israel wisely invests heavily in both, maintaining the world's most layered missile defense while operating F-15I Ra'am aircraft specifically configured for long-range strike. The $100M F-15E versus $2–3M Arrow-2 comparison is misleading — the F-15E is reusable across thousands of sorties while each Arrow-2 is consumed on engagement. Across a full conflict cycle, both deliver irreplaceable value that cannot be substituted by the other.
Frequently Asked Questions
Can Arrow-2 shoot down aircraft like the F-15E?
No. Arrow-2 is designed exclusively to intercept ballistic missiles during their terminal descent phase within the atmosphere. It lacks the guidance and engagement profile to target maneuvering aircraft. Israel uses separate systems — the Python-5, Derby, and AIM-120 AMRAAM air-to-air missiles — for anti-aircraft defense.
Could F-15E Strike Eagles destroy Iranian missiles before launch?
In theory, yes — F-15E aircraft armed with precision munitions can destroy TELs (transporter erector launchers) and fixed missile sites. In practice, locating mobile launchers is extremely difficult, as demonstrated during the 1991 Gulf War Scud hunt. Modern ISR has improved targeting, but mobile TELs in dispersed, camouflaged positions remain challenging targets.
How many Arrow-2 interceptors does Israel have?
Israel does not publicly disclose exact Arrow-2 inventory numbers. Estimates from defense analysts suggest 100–200 ready interceptors across multiple batteries. Production is jointly managed by IAI and Boeing, with the US contributing significant funding through the Israel Missile Defense Organization cooperation program.
What is the F-15I Ra'am and how is it different from the F-15E?
The F-15I Ra'am (Thunder) is Israel's customized variant of the F-15E, featuring Israeli-made electronic warfare systems, conformal fuel tanks optimized for long-range strike, and integration with Israeli munitions including the Delilah cruise missile. It was specifically acquired as a long-range strike platform capable of reaching Iran — approximately 1,750 km combat radius.
Why does Israel need both Arrow-2 and F-15 strike aircraft?
Arrow-2 defends against missiles already in flight (right-of-launch) while F-15I aircraft can strike launch sites before missiles fire (left-of-launch). Neither capability alone is sufficient: Arrow-2 has finite interceptors that can be exhausted by sustained salvos, while F-15 strikes cannot guarantee all launchers are destroyed. Together they form a sword-and-shield strategy that provides both immediate defense and long-term threat reduction.
