For the reason that begin of Israel’s operation in opposition to Iran, the Iranian have fired 500 ballistic missiles and greater than 1,000 suicide drones (loitering munitions) at Israel. The drones are utilized by the Iranians to inflict harm themselves but in addition to attempt to overload Israel’s air protection techniques in mixed assaults.
In contrast to the operation in opposition to Hezbollah, by which it was clear that Israel was having issue in coping with the specter of drones – within the conflict in opposition to Iran, Israel appears to now know what’s required. Loitering munitions have distinctive challenges that aren’t typical of air protection in opposition to missiles and rockets. To this finish, Israel operates the Arrow 3, Arrow 2, David’s Sling and Iron Dome, which may solely present a partial response in opposition to drones.
The identical drones have been flying from Ukraine to Russia and vice versa since Russian President Vladimir Putin’s determination to invade Ukraine in February 2022, turning that conflict right into a sort of “testing floor” for the business. In October 2023, the Ukrainians have been in a greater place than Israel on this space, however right this moment Israel manages to realize interception charges which can be at least these of the Ukrainians and even exceed them.
The best way to cope with them is totally different
The challenges of assault drones are distinctive. Firstly, it evades radar. The flexibility to obtain a radar sign from the drone is low, partly as a result of its small measurement and its means to fly at low altitudes the place radar is much less efficient. As well as, the Iranians produce the UAVs from composite supplies, which they paint in shades of gray-black. The connection between the composition of the supplies and the colour causes low reflection of radar waves, and even their absorption.
Israel and Ukraine have one thing in widespread when it comes to the kind of UAVs which can be used in opposition to them. Russia depends on Iranian UAV applied sciences basically and the Shahed 136 specifically. All through the conflict, the Russians have even developed impartial drone manufacturing capabilities, which allowed them on the night time between Sunday and Monday, for instance, to launch greater than 350 drones in the direction of Kiev. The mixture of the amount and the shared border between the nations meant that though the Ukrainians intercepted the bulk, there have been nonetheless hits within the heart of the capital.
In distinction, in Israel, drone strikes and many of the alerts have been targeting the jap border, from the Golan Heights to Eilat. This means early stage capabilities of identification, detection, and interception, even exterior the nation. Inside this framework, helicopters and fighter jets are deployed, amongst different issues. This creates a scenario by which coping with drones is way more costly than they’re price. A Python air-to-air missile could value about $500,000, in comparison with the $30,000 {that a} Shahed 136 prices. The price of an Iron Dome interception miissile is the same as the price of a Shahed 136, however it’s a system that suffers from limitations in comparison with UAVs.

Can Israel deal with all of Iran’s ballistic missiles?
Dr. Yehoshua Kalisky, a senior researcher at Tel Aviv College’s Institute for Nationwide Safety Research (INSS), explains that whereas a rocket strikes on a predetermined ballistic trajectory, an Iron Dome is constructed for it, and on this method it’s doable to calculate the place you wish to perform the strike – “A drone is a loitering munition with no fastened trajectory, and due to this fact you want a complicated monitoring system to hit it.”
Iron Dome is anticipated to be operationally bolstered beginning within the final quarter of this yr by the air protection system utilizing the Iron Beam laser. Each techniques will probably be operated from the identical management automobile, with Iron Dome designed for ranges of 40 kilometers, whereas Iron Beam is designed for a spread of as much as 10 kilometers, utilizing a strong laser beam with an influence of about 100 kilowatts.
Efficient, regardless of its disadvantages
Laser know-how is just not good, and a significant problem in it’s its latency: the diploma to which the beam weakens because it strikes away from the launcher. Cloudy climate, fog, or mist additionally restrict the laser’s exercise and decrease its effectiveness, and it additionally works in a column and strikes from goal to focus on. Which means in opposition to a swarm of UAVs, for instance, it will likely be in a position to intercept just one UAV. The important benefit is the negligible value of interception: about $5-10. Subsequently, combining it with machine gun fireplace could present a major response for drones.
“The laser wants a dwelling time on the goal to ‘prepare dinner’ it, if it hits,” notes Dr. Kalisky. “The required dwelling time will depend on the fabric the UAV is manufactured from. The construction of the fabric is vital as a result of bodily parameters.”
Lastly, the facility of the laser beam is especially vital. Whereas the world makes use of techniques with an influence of 20 kilowatts, Iron Beam is anticipated to be 5 occasions extra highly effective. “A 100 kilowatt laser, I estimate, would trigger mechanical failure in a short time. In lower-power techniques, it requires just a few seconds.”
