The Karabakh War: How Turkish and Israeli Drones Changed the Rules of the Battlefield

In the Nagorno-Karabakh war, which lasted 44 days from September 27 to November 10, 2020, and ended with a Russia-brokered ceasefire, Azerbaijan used Turkish Bayraktar TB2 drones alongside Israeli Harop loitering munitions made by Israel Aerospace Industries (IAI) to inflict heavy losses on Armenia's armor and air-defense systems. The open-source research project Oryx documented and confirmed the destruction, damage, or capture of dozens of Armenian military vehicles, with credible estimates putting the toll at roughly 247 tanks, 138 artillery systems, and 52 air-defense systems destroyed by drone-guided strikes.

An Expensive S-300 Versus Cheap Loitering Munitions

The event that marked the turning point in military-technological coverage of the war took place on October 9, 2020. A Harop unmanned aerial vehicle, manufactured by Israel Aerospace Industries, located and struck an Armenian S-300 radar system, one of the most advanced and expensive air-defense systems in the Armenian military's arsenal. The strike effectively eliminated Armenia's advanced air-defense capability in the region and raised a question that troubled foreign analysts: how does a system estimated to cost tens of millions of dollars fall victim to a disposable and significantly cheaper aircraft?

The Harop, sometimes called a 'kamikaze drone,' is not a classic strike weapon. It loiters over the target area for extended periods, scanning and identifying targets, and only then dives and detonates on direct impact. This combination of intelligence gathering and strike capability in a single, relatively cheap platform is what makes it especially dangerous against air-defense systems designed mainly to intercept missiles and conventional aircraft, not small, slow-moving objects circling in the air before they attack.

The Hard Numbers Behind the Armenian Military's Collapse

Beyond the documented strike on the S-300, the broader picture that emerged from open-source visual evidence collected by researchers, led by the Oryx team, shows a systematic collapse of Armenian armor and air-defense capabilities throughout all 44 days of fighting.

• Dates of fighting: September 27 to November 10, 2020
• Armenian tanks destroyed in drone strikes: approximately 247
• Artillery systems destroyed: approximately 138
• Air-defense systems destroyed: approximately 52
• Outcome: Russia-brokered ceasefire on November 10, 2020

The First War Decided from the Unmanned Skies?

Since the ceasefire, military analysts around the world have referred to the Karabakh conflict as a milestone: the first time an entire military campaign was determined to a significant extent by unmanned systems rather than by armored forces, manned air power, or traditional artillery. The Turkish-Israeli combination, the TB2 for precision strikes at medium range and the Harop for eliminating sensitive air-defense targets, managed to paralyze Armenia's defense array even before ground forces fully entered the picture.

Beyond the immediate result on the ground, the war sparked a broad discussion among militaries and procurement officials worldwide over the value of investing in expensive, complex air-defense systems versus cheap, precise, and expendable platforms. The question of whether high-value military assets can be defended at all against a swarm of cheap attack drones remains open, and Western militaries too have begun reexamining their air-defense mix in light of the results.

The Israeli engineering achievement behind the Harop: a development by Israel Aerospace Industries that proved itself on a real battlefield and reestablished Israel's standing as a leading player in the global loitering-munitions field.
