Overview
Comparing the Arrow-2 interceptor with Turkey's SOM cruise missile juxtaposes two fundamentally different approaches to modern air warfare — one designed to destroy incoming ballistic missiles, the other engineered to penetrate enemy air defenses and strike hardened targets. This cross-category analysis matters because both systems represent the pinnacle of their respective nation's indigenous defense capability, and both operate in the same Eastern Mediterranean theater where Turkish and Israeli strategic interests increasingly intersect. Arrow-2, operational since 2000, anchors Israel's layered ballistic missile defense as the endoatmospheric tier beneath Arrow-3. SOM, fielded in 2012, gives Turkey autonomous stand-off strike capability without dependence on U.S. JASSM exports. For regional defense planners, understanding how a defensive interceptor and an offensive cruise missile compare in cost, doctrine, and capability illuminates broader questions about the offense-defense balance shaping Middle Eastern security architecture in 2025 and beyond.

Head-to-Head Analysis
Mission Capability & Versatility
Arrow-2 is a single-mission system — it exists to kill incoming ballistic missiles in the upper atmosphere, and it does that exceptionally well. Its Mach 9 speed and active radar seeker give it the kinematic performance to intercept targets traveling at several kilometers per second. SOM, by contrast, offers broader mission versatility: it can strike fixed targets, mobile assets, and hardened installations using interchangeable warhead types. Its IIR terminal seeker enables autonomous target recognition without GPS dependency in the final phase. SOM can be retargeted in flight, while Arrow-2 commits to a single engagement trajectory. However, Arrow-2's defensive mission is arguably more strategically critical — stopping a ballistic missile prevents catastrophic damage, while SOM delivers one of many available strike options.
SOM offers greater versatility, but Arrow-2's specialized defensive mission carries higher strategic weight per engagement.
Technology & Guidance Sophistication
Arrow-2 relies on the Super Green Pine radar for fire control, feeding target data to the interceptor's onboard active radar seeker for terminal guidance. This system must solve one of the hardest problems in engineering: hitting a bullet with a bullet at closing speeds exceeding Mach 12. SOM employs a multi-modal guidance suite — INS for midcourse, TERCOM for terrain-following navigation, GPS for precision updates, and an imaging infrared seeker for terminal accuracy. This layered approach makes SOM resistant to GPS jamming, as TERCOM and IIR provide independent targeting. Arrow-2's guidance is optimized for speed and reaction time; SOM's is optimized for precision and electronic resilience. Both represent top-tier engineering within their categories, but SOM's multi-modal approach reflects more recent design philosophy.
SOM's multi-modal guidance is more technologically advanced and jam-resistant; Arrow-2's guidance solves a harder kinematic problem.
Cost & Production Economics
At $2-3 million per interceptor, Arrow-2 is roughly two to three times more expensive than a SOM missile at approximately $1 million. However, this comparison requires context. Arrow-2 defends against threats that would cause billions in damage — a single successful intercept of a ballistic missile targeting critical infrastructure could save thousands of lives and tens of billions of dollars. SOM's cost-per-effect is excellent for strike missions, undercutting Western equivalents like JASSM ($1.6M) while delivering comparable capability. Turkey manufactures SOM domestically with no export restrictions, enabling unconstrained production scaling. Arrow-2 involves U.S. co-production with Boeing, creating supply chain dependencies. For sustained conflict, SOM's lower cost and indigenous supply chain provide a significant logistical advantage.
SOM wins on unit economics and production independence; Arrow-2's cost is justified by the catastrophic consequences of interception failure.
Combat Record & Operational Maturity
Arrow-2 holds a decisive advantage in combat validation. Its 2017 intercept of a Syrian SA-5 missile marked the first operational use of an anti-ballistic missile system by any nation. During the April 2024 Iranian attack — which involved over 300 projectiles — Arrow-2 worked alongside Arrow-3 to intercept ballistic missiles in the upper layers of Israel's defense. This real-world performance under massive salvo conditions provides irreplaceable confidence in the system's reliability. SOM has been used in Turkish cross-border operations in Syria and northern Iraq, primarily against PKK and YPG targets, launched from F-16 and F-4E platforms. While these operations confirmed SOM's precision and reliability, they occurred against adversaries with minimal air defense capability, providing limited insight into SOM's survivability against modern IADS.
Arrow-2 has a far more demanding and validated combat record; SOM is combat-proven but only against permissive air defense environments.
Strategic Independence & Export Potential
Both systems represent national defense sovereignty milestones. Arrow-2 was co-developed with Boeing under the Arrow Weapon System program, partially funded by U.S. Missile Defense Agency dollars. This relationship provides Israel with advanced technology but creates dependency on Washington's political approval for use and export. SOM is entirely indigenous to Turkey — TÜBİTAK SAGE and Roketsan developed it without foreign technology transfer, meaning Ankara faces no export restrictions or political leverage from suppliers. The SOM-J variant's integration into the F-35 internal weapons bay potentially opens NATO export markets. Turkey has already marketed SOM to several countries. Arrow-2, by contrast, is restricted by U.S. ITAR regulations and has only been exported to one country — no confirmed foreign sales beyond Israel.
SOM provides Turkey with complete strategic autonomy and export potential; Arrow-2's U.S. co-development creates both capability benefits and political constraints.
Scenario Analysis
Iranian ballistic missile salvo against Israeli airbases
In this scenario, Arrow-2 is the directly relevant system. During the April 2024 attack, Iran launched approximately 120 ballistic missiles at Israel, and Arrow-2 operated alongside Arrow-3 to defeat them in the upper atmosphere. Arrow-2's Mach 9 speed and purpose-built engagement profile make it essential for this mission. SOM has no role in this defensive scenario — it cannot intercept incoming missiles. However, if Turkey were a coalition partner, SOM could contribute to the broader campaign by striking Iranian launch sites, air defense nodes, or command facilities in a retaliatory or preemptive context. The strike mission would require air superiority and suppression of Iranian IADS first, limiting SOM's immediate utility during the initial defensive phase.
Arrow-2 — purpose-built for exactly this threat. SOM is irrelevant to missile defense but could contribute to retaliatory strike planning.
Turkish stand-off strike against hardened military targets in a contested environment
SOM excels in this scenario. Its stealthy airframe, terrain-following TERCOM navigation, and IIR terminal seeker allow it to approach targets at low altitude, minimizing radar exposure. The 250 km range keeps launch aircraft outside most short-range air defense envelopes. Against hardened targets, SOM's penetration warhead variant can defeat reinforced concrete structures. Arrow-2 has no offensive capability and cannot contribute to strike operations. If Turkey faced an adversary with ballistic missiles, Arrow-2 would be the relevant defensive system — but Israel has never exported Arrow-2, and Turkey relies on its own S-400 and Hisar systems for air defense. A salvo of 8-12 SOMs against a single target complex could overwhelm point defenses through simultaneous time-on-target attacks.
SOM — designed precisely for this mission. Arrow-2 cannot perform strike operations.
Eastern Mediterranean escalation with cruise missile and ballistic missile threats
A regional escalation scenario highlights how these systems serve complementary rather than competing roles. Arrow-2 would defend Israeli population centers and military installations against ballistic missile threats from Iran or its proxies, operating within the layered defense architecture alongside Arrow-3, David's Sling, and Iron Dome. SOM would enable Turkish offensive operations against hostile targets — whether striking enemy air defense radars to create corridors, hitting command nodes, or destroying logistics hubs. The systems never compete for the same mission. In a coalition context, Israeli Arrow-2 batteries defending Turkish bases while Turkish F-16s armed with SOMs struck shared adversary targets would represent effective capability integration. The $1M SOM striking a $300M SAM battery while the $2.5M Arrow-2 defeats a $5M ballistic missile illustrates favorable cost-exchange ratios for both.
Neither — these systems are complementary. Combined employment maximizes coalition effectiveness across offense and defense.
Complementary Use
Arrow-2 and SOM represent the defensive and offensive pillars that a modern military requires simultaneously. In a coalition scenario, Arrow-2 batteries would protect airbases and critical infrastructure from ballistic missile attack, creating the secure operating environment from which Turkish F-16s could launch SOM strikes against enemy targets. This defense-offense symbiosis mirrors NATO doctrine: you cannot conduct sustained strike operations if your airbases are destroyed by incoming ballistic missiles, and passive defense alone does not eliminate the threat source. Israel's layered defense — with Arrow-2 as the endoatmospheric tier — buys time for offensive strike packages to destroy enemy launchers. SOM's stand-off range keeps expensive combat aircraft outside point defense envelopes while Arrow-2 ensures they have a base to return to.
Overall Verdict
Arrow-2 and SOM are not competitors — they are answers to entirely different questions. Arrow-2 asks: how do you survive an incoming ballistic missile attack? SOM asks: how do you destroy a hardened target 250 kilometers away without losing your aircraft? Comparing them reveals the offense-defense balance that defines modern warfare. Arrow-2 is the more consequential system strategically — successful ballistic missile defense prevents catastrophic outcomes measured in thousands of lives and billions in damage. Its 25-year operational record and combat-proven performance during the largest ballistic missile attack in history (April 2024) make it one of the most validated defense systems ever fielded. SOM is the more versatile and cost-effective system tactically — at one-third the price, with complete production sovereignty and growing export potential. Turkey's achievement in fielding an indigenous cruise missile with stealthy characteristics and multi-modal guidance is strategically significant for the NATO alliance. For a defense planner evaluating regional architecture, both systems are essential investments. The right question is not which to choose, but how to ensure both defensive interceptors and offensive stand-off munitions are available in sufficient quantity to sustain a campaign.
Frequently Asked Questions
Can Arrow-2 intercept cruise missiles like the SOM?
Arrow-2 was designed to intercept ballistic missiles in the upper atmosphere, not low-flying cruise missiles. Cruise missiles like SOM fly at low altitudes using terrain-following navigation, making them targets for systems like David's Sling, Barak-8, or Patriot rather than Arrow-2. Israel's layered defense assigns different systems to different threat profiles.
Is Turkey's SOM cruise missile comparable to the American JASSM?
SOM and JASSM share the stand-off cruise missile role but differ significantly. JASSM-ER has a 1,000 km range versus SOM's 250 km, and carries a larger 450 kg warhead. However, SOM costs roughly $1M versus JASSM's $1.6M, and Turkey manufactures it domestically without ITAR restrictions. The SOM-J variant is being developed for F-35 internal carriage, bringing it closer to JASSM's integration level.
How did Arrow-2 perform during the April 2024 Iran attack?
During Iran's April 13-14, 2024 attack involving approximately 120 ballistic missiles, 30 cruise missiles, and 170 drones, Arrow-2 and Arrow-3 intercepted the ballistic missile component in the upper layers of Israel's defense. The combined intercept rate exceeded 99%. Arrow-2 served as the endoatmospheric backup layer, engaging targets that Arrow-3 missed or that flew lower trajectories.
What is the SOM-J variant and why does it matter for F-35?
SOM-J is a modified version of the SOM cruise missile designed to fit inside the F-35's internal weapons bay, preserving the aircraft's stealth profile. This is significant because Turkey was removed from the F-35 program in 2019, but SOM-J development has continued for potential export customers. If Turkey's F-35 access is restored, SOM-J would give Turkish F-35s an indigenous stand-off strike capability without depending on American munitions.
Why does Arrow-2 cost more than SOM if it has no warhead for ground attack?
Arrow-2's $2-3M cost reflects the extreme engineering required to intercept targets moving at several kilometers per second with closing speeds exceeding Mach 12. Its solid-fuel dual-pulse rocket motor, active radar seeker, and high-G maneuvering capability demand precision manufacturing. The system also includes proportional costs of the Super Green Pine radar and battle management system. SOM's subsonic flight profile requires less extreme materials and propulsion engineering.
