Overview
The Arrow-2 and Buk-M2 Viking represent fundamentally different philosophies of air and missile defense. Arrow-2, jointly developed by Israel Aerospace Industries and Boeing, is a dedicated anti-ballistic missile interceptor designed to destroy incoming theater ballistic missiles during their terminal phase within the atmosphere. Buk-M2, built by Russia's Almaz-Antey, is a mobile medium-range surface-to-air missile system designed primarily to shoot down aircraft, cruise missiles, and precision-guided munitions at ranges up to 50 km. While their primary mission sets barely overlap, both systems have seen consequential combat use — Arrow-2 achieved history's first operational ABM intercept against a Syrian SA-5 in March 2017, while the Buk system gained infamy when Russian-backed separatists used a Buk-M1 to shoot down Malaysia Airlines Flight MH17 over eastern Ukraine in July 2014, killing all 298 people aboard. Comparing these systems illuminates the stark difference between Israel's specialized missile defense architecture and Russia's layered conventional air defense approach, both of which have been stress-tested in the ongoing Middle Eastern conflict theater.

Head-to-Head Analysis
Range & Engagement Envelope
Arrow-2 dominates in engagement range with a 150 km intercept capability specifically optimized for theater ballistic missiles descending at extreme velocities. Its Super Green Pine radar can detect targets at over 500 km, providing early tracking and fire control. Buk-M2's 50 km range serves a completely different tactical need — medium-range air defense against aircraft and cruise missiles operating at lower altitudes. The Buk's 9S36 TELAR radar tracks targets at 36 km. In raw numbers, Arrow-2 covers roughly 9 times the defended area. However, Buk-M2 operates in a denser, more cluttered engagement environment where shorter-range, rapid-reaction capability is the design priority. Each system's range is optimized for its mission set — Arrow-2 needs distance to intercept fast-descending ballistic warheads, while Buk-M2 needs quick reaction time against low-flying threats.
Arrow-2 has vastly superior range, but the comparison is asymmetric — each system's range matches its mission.
Guidance & Kill Probability
Arrow-2 uses an active radar seeker with fire-and-forget terminal guidance, meaning the missile autonomously tracks its target in the final phase without requiring continuous radar illumination from the ground. This is essential against ballistic missile targets traveling at Mach 10+ with minimal engagement windows. Its directional fragmentation warhead is specifically designed to destroy ballistic warheads. Buk-M2 relies on semi-active radar homing (SARH), requiring the TELAR's 9S36 radar to continuously illuminate the target until impact. This creates vulnerability — the illuminating radar is detectable and targetable by anti-radiation missiles like the AGM-88 HARM. Buk-M2 can engage up to four targets simultaneously per TELAR, but each engagement consumes a radar channel. Arrow-2's fire-and-forget approach allows multiple simultaneous intercepts without this bottleneck, though its engagement is against a fundamentally more difficult target class.
Arrow-2's active seeker provides superior guidance architecture, though Buk-M2's SARH is adequate for its conventional air defense role.
Mobility & Survivability
Buk-M2 holds a decisive advantage in tactical mobility. Its self-propelled tracked TELAR (Transporter Erector Launcher and Radar) can displace from a firing position and be combat-ready at a new site within 5 minutes. This shoot-and-scoot capability is critical for surviving in environments where SEAD/DEAD aircraft hunt SAM sites. The entire Buk battery — command post, acquisition radar, TELARs, and transloader vehicles — moves on tracks across rough terrain. Arrow-2, by contrast, operates from semi-fixed positions that require significant infrastructure including the Super Green Pine radar installation and dedicated command centers. While Arrow-2 batteries can relocate, the process takes hours rather than minutes. In the Syrian theater, Buk-M2's mobility has been essential for surviving Israeli airstrikes that routinely destroy fixed air defense positions. Arrow-2 relies on its deep rear positioning within Israeli territory for survivability.
Buk-M2 is far more tactically mobile, making it significantly harder to target and destroy in combat.
Combat Record & Proven Performance
Both systems have significant combat histories, though with very different outcomes. Arrow-2 achieved a historic milestone in March 2017 when it intercepted a Syrian S-200 (SA-5) missile that had overflown its target — the first-ever operational intercept by a purpose-built ABM system. During Iran's April 2024 attack, Arrow-2 worked alongside Arrow-3 to intercept incoming ballistic missiles with reported near-perfect success rates. Buk-M2's combat record is shadowed by the MH17 disaster in July 2014, when a Buk-M1 operated by Russian-backed separatists shot down a civilian airliner over eastern Ukraine, killing 298 people. In Syria, Buk systems contributed to shooting down an Israeli F-16I in February 2018 — the first Israeli combat aircraft loss since 1982. The Buk's record demonstrates both capability against advanced aircraft and catastrophic consequences of targeting errors in contested airspace.
Arrow-2 has a cleaner, more successful combat record. Buk-M2 demonstrated lethality but also catastrophic misidentification risk.
Cost & Availability
The cost comparison is complex because these systems serve different roles and are priced differently. An Arrow-2 interceptor costs approximately $2–3 million per round, but the entire Arrow Weapon System including Super Green Pine radar, launch batteries, and battle management represents billions in investment. A complete Buk-M2 battery costs roughly $100 million, with individual 9M317 missiles costing approximately $1.5 million each. Buk-M2 is widely exported — operators include Russia, Syria, Egypt, Venezuela, and several other nations — making it more broadly available on the global market. Arrow-2 is restricted to Israel, with no export customers despite occasional interest from other nations, due to U.S. technology sharing restrictions and Israeli security concerns. For nations seeking medium-range air defense, Buk-M2 is accessible; Arrow-2-class ABM capability remains exclusive to Israel and its U.S.-underwritten defense architecture.
Buk-M2 is more affordable and globally accessible. Arrow-2 is a strategic asset restricted to Israel.
Scenario Analysis
Defending against an Iranian ballistic missile salvo targeting Israeli cities
In an Iranian ballistic missile attack — as occurred in April 2024 when Iran launched over 110 ballistic missiles — Arrow-2 is the correct system for upper-tier intercept of Shahab-3, Emad, and Ghadr-class medium-range ballistic missiles during their terminal descent phase. Operating at 10–50 km altitude, Arrow-2 engages threats that Buk-M2 physically cannot reach due to the extreme reentry velocities (Mach 10+) and high altitude. Buk-M2's Mach 4 interceptor and 25 km altitude ceiling make it incapable of engaging theater ballistic missiles. During the April 2024 attack, Israel's multi-layered defense — Arrow-3 for exoatmospheric intercept, Arrow-2 for upper-endoatmospheric, David's Sling for lower tier — reportedly achieved a 99% intercept rate. Buk-M2 has no role in this scenario.
Arrow-2 is the only viable system. Buk-M2 cannot engage theater ballistic missiles at terminal velocities.
Defending a forward airbase against Israeli F-35I and F-16I strike packages
Against conventional air attack by fourth- and fifth-generation fighter aircraft, Buk-M2 is the appropriate system. Its 50 km engagement range and rapid-reaction capability (12 seconds from detection to launch) make it effective against strike aircraft and standoff munitions. In February 2018, Syrian air defenses including Buk-series systems contributed to downing an Israeli F-16I — demonstrating that even advanced Western aircraft are vulnerable. The Buk-M2's tracked mobility allows it to reposition after firing, complicating suppression of enemy air defense (SEAD) operations. Arrow-2 is not designed for anti-aircraft engagement — its interceptor is optimized for ballistic missile trajectories and its fire control system tracks theater ballistic missiles, not maneuvering aircraft. Deploying Arrow-2 against fighter jets would be like using a sniper rifle to stop a car.
Buk-M2 is designed precisely for this scenario. Arrow-2 has no anti-aircraft capability.
Integrated air defense against mixed threats — cruise missiles, drones, and ballistic missiles simultaneously
A mixed-threat saturation attack — combining Shahed-136 drones, Hoveyzeh cruise missiles, and Emad ballistic missiles — demands layered defense where both system types contribute. Arrow-2 handles the high-altitude ballistic threat layer at 10–50 km, engaging MRBMs before they reach their terminal dive. Buk-M2 operates in the medium-altitude band (0.015–25 km), intercepting cruise missiles and potentially larger drone targets that fly below Arrow-2's engagement envelope but above short-range systems like Tor-M1 or Pantsir. In this scenario, the two systems are complementary rather than competitive — Arrow-2 clears the ballistic threat while Buk-M2 (or its equivalents like David's Sling or Patriot) handles aerodynamic threats. The key coordination challenge is battle management to prevent wasting interceptors on targets another layer can handle more efficiently.
Neither alone is sufficient. Both systems are needed in their respective layers for comprehensive defense.
Complementary Use
Arrow-2 and Buk-M2 occupy entirely different layers of an integrated air defense system and would complement each other if operated by the same force. Arrow-2 handles the upper-tier anti-ballistic missile mission at altitudes of 10–50 km, while Buk-M2 covers the medium-range conventional air defense band from near-ground level to 25 km. Russia achieves a similar layering with S-400 (long-range), Buk-M2/M3 (medium-range), Tor-M2 (short-range), and Pantsir-S1 (point defense). Israel mirrors this with Arrow-3 (exoatmospheric), Arrow-2 (upper endoatmospheric), David's Sling (medium), and Iron Dome (short-range). In practice, Israel uses David's Sling rather than Buk-M2 in the medium tier, but the architectural principle is identical — no single system can defend against the full spectrum of aerial threats, making layered integration essential for survivable defense.
Overall Verdict
Arrow-2 and Buk-M2 Viking are not direct competitors — they are fundamentally different weapon systems designed for different threat classes. Arrow-2 is a dedicated anti-ballistic missile interceptor with no peer in its specific mission: destroying theater ballistic missiles during endoatmospheric terminal descent. Its Mach 9 speed, 150 km range, active radar seeker, and directional fragmentation warhead are all optimized for this single, extraordinarily demanding task. It has proven itself in combat against real ballistic missile threats and remains the backbone of Israel's upper-tier missile defense. Buk-M2 is a versatile, mobile medium-range SAM designed to shoot down aircraft and cruise missiles. Its mobility, multi-target engagement capability, and proven lethality against advanced fighters (the 2018 F-16I shootdown) make it a capable conventional air defense system. However, it carries the permanent stigma of the MH17 disaster, which exposed critical shortcomings in target identification procedures. For a defense planner, the choice is dictated entirely by threat: ballistic missiles demand Arrow-2-class interceptors; conventional air threats require Buk-M2-class SAMs. No responsible air defense architecture would substitute one for the other.
Frequently Asked Questions
Can the Arrow-2 shoot down aircraft like the Buk-M2?
No. Arrow-2 is designed exclusively to intercept ballistic missiles during their terminal descent phase. Its fire control radar, flight profile, and warhead are optimized for targets traveling at Mach 10+ on predictable ballistic trajectories. It has no capability against maneuvering aircraft, cruise missiles, or drones. Israel uses David's Sling and Iron Dome for those threat categories.
Can the Buk-M2 intercept ballistic missiles?
The Buk-M2 has a very limited capability against short-range tactical ballistic missiles, but it cannot intercept medium-range or long-range ballistic missiles. Its Mach 4 interceptor speed and 25 km altitude ceiling are insufficient to engage targets descending at Mach 10+ from 50+ km altitude. For ballistic missile defense, Russia relies on the S-400's 48N6 missiles and the A-235 Nudol system.
Was a Buk missile used to shoot down MH17?
Yes. The Dutch Safety Board and Joint Investigation Team conclusively determined that Malaysia Airlines Flight MH17 was destroyed on July 17, 2014 by a 9M38-series missile fired from a Buk-M1 TELAR operated by Russia's 53rd Anti-Aircraft Missile Brigade. All 298 people aboard were killed. The missile was transported from Russia into separatist-held eastern Ukraine and returned to Russia afterward.
How much does an Arrow-2 interceptor cost compared to a Buk-M2 missile?
An Arrow-2 interceptor costs approximately $2–3 million per round, while a Buk-M2's 9M317 missile costs roughly $1.5 million each. However, the total system costs differ enormously — the Arrow Weapon System with its Super Green Pine radar represents billions in investment, while a complete Buk-M2 battery costs approximately $100 million.
Did a Buk missile really shoot down an Israeli F-16?
On February 10, 2018, an Israeli F-16I was shot down by Syrian air defenses during Operation House of Cards. While the specific system that downed the aircraft is debated — Syrian forces fired multiple SAM types including S-200, Buk, and Pantsir — the Buk system was among those engaged. It was the first Israeli combat aircraft loss since 1982.
