IAI Harop

A loitering munition is an unmanned aerial weapon that flies to a target area, circles there for an extended period, and then attacks a target by self-destruction (kamikaze attack). It combines features of an unmanned aerial vehicle (UAV — controlled flight, sensors) with a guided missile (one-way attack with explosive warhead). The defining feature is the ability to wait — minutes to hours — before attacking, allowing the operator to identify the right target. The IAI Harop is one of the original platforms in this class and the most combat-influential non-Russian / non-Iranian system in it.

Different roles. The Shahed-136 is a low-cost (~$20-50K USD), one-way attack drone designed for mass strikes against fixed targets — minimal sensors, GPS / inertial navigation only, no real-time targeting. The Harop is a sophisticated reconnaissance-strike system (~$1-2M USD per unit) with EO/IR + anti-radar seekers, two-way datalinks, and man-in-the-loop targeting. Operators can pick the Harop's target after launch; the Shahed-136 cannot be redirected. Harops are typically used against high-value targets (radars, tanks, command posts); the Shahed-136 is typically used against urban infrastructure or area saturation. Both are kamikaze drones but very different in use.

Decisively. Azerbaijani Harops conducted dozens of confirmed strikes against Armenian air-defence systems (S-300P / S-300V, 9K33 Osa, 9K35 Strela-10, Tor-M2KM), tanks (T-72, T-80), and command-and-control vehicles during the 44-day conflict (September-November 2020). The pairing of the Harop's anti-radar role against Armenian S-300 systems and the Bayraktar TB2's battlefield-strike role against ground forces effectively eliminated Armenian air defence within the first 7-10 days of the conflict, allowing follow-on Azerbaijani ground operations. The Nagorno-Karabakh experience accelerated global procurement of kamikaze drones and sharply increased export demand for the Harop.

No — the Harop is a one-way attack munition. However, unlike simpler kamikaze drones, the Harop can abort an attack run and return to loiter if the operator decides not to commit the weapon, and re-attack later. This is rare in the class — most one-way drones, once committed to an attack, cannot abort without detonating. The Harop's 9-hour endurance allows extended circling and re-attack cycles. Once fuel is exhausted, the airframe is lost; in standard use, the Harop is intentionally expended on a target.

Approximately $1-2M USD per unit (depending on quantity and configuration). Far more expensive than mass-production attack drones (Shahed-136: ~$20-50K USD; Switchblade-300: ~$6K USD) but dramatically more powerful — 9-hour endurance, dual-mode seeker, two-way datalink, abort-and-re-attack option. The cost-effectiveness calculation depends on target value: against a $200M USD Armenian S-300 battery, even a $2M USD Harop is a strongly favourable trade.

Israel Aerospace Industries (IAI) MBT Missiles Division (also known as MLM and IAI Systems Missiles & Space Group). Development started in the early 2000s as an evolution of the earlier IAI Harpy anti-radiation munition (designed in the 1990s, in service from ~1994). First Harop service entry: 2009. The Harop is one of IAI's flagship export products and has been continuously upgraded with improved seekers, datalinks, and warheads over its service life.
