Israel’s Laser-based ‘Iron Beam’ interception system declared operational
An attack by a single drone can present a dangerous threat. But now some countries are launching attacks by swarms of drones (which is obviously much more difficult to counter). Laser counter-measures should provide greatly enhanced counter-measures.

Israel’s high-powered laser interception system, dubbed “Iron Beam,” has been declared operational after completing development and final tests, and is set to be delivered to the military by the end of the year, the Defense Ministry and manufacturer Rafael said on Wednesday.
The Iron Beam has been in development for over a decade; it was first unveiled in 2014 . During the current war, a lower-powered version of the system was used by the Israel Defense Forces to shoot down Hezbollah drones launched from Lebanon.
The ministry said its Directorate of Defense Research & Development (DDR&D), the Israeli Air Force, and the Rafael defense firm “successfully completed an advanced series of operational tests, which lasted several weeks, to demonstrate the capabilities of the high-power laser system.”
It said the test involved the interception of rockets, mortars, and drones by the Iron Beam.
“The series of tests, conducted at a testing ground in southern Israel, concludes the development process and constitutes the final stage before delivering the system for operational use in the IDF,” the ministry said.
The Iron Beam is not meant to replace the Iron Dome or Israel’s other air defense systems, but to supplement and complement them, shooting down smaller projectiles and leaving larger ones for the more robust missile-based batteries such as the David’s Sling and Arrow systems.
As long as there is a constant source of energy for the laser, there is no risk of it ever running out of ammunition. Officials have hailed it as a potential “game-changer” in the battle against projectile attacks.
THe main downside of a laser system is that it does not function well in low visibility, including heavy cloud cover or other inclement weather.
A lower-powered and shorter-range version of the laser interceptor system used by the IDF’s newly revived 946th Air Defense Battalion , which operates anti-drone systems, shot down some 35 Hezbollah drones over northern Israel last year.
With the Iron Beam being declared operational, “a significant leap in the operational capabilities of the Air Defense Array is expected, through the long-range laser weapon system,” the ministry added.
In June, Rafael showcased at the Paris Air Show its family of “high-energy laser weapon systems,” including the Iron Beam 450, an upgraded version of the Iron Beam; the Iron Beam M, a compact and mobile version of the laser interceptor, designed to be mounted on a truck and used by ground forces or to protect strategic sites; and the Lite Beam, a lightweight, compact, and lower-powered laser interceptor designed to be mounted on armored personnel carriers or other armored vehicles during ground operations.
Rafael also said it was developing a maritime version of the laser interceptor, which could be deployed on Navy boats to protect assets at sea.
Wednesday’s announcement was hailed by officials, with Defense Minister Israel Katz saying the Iron Beam “places the State of Israel at the forefront of global military technology and makes the State of Israel the first country to possess this capability.”
“This is not only a moment of national pride, but a historic milestone for our defense envelope: a fast, precise interception at marginal cost that joins the existing defensive tools and changes the threat equation,” he said.
Violations of the rules will be cancwelled without notice!

Hopefully they will, because IMO Iran and its proxies will never stop attacking Israel.

Hopefully it did not start any wildfires in California or MTG would be proven right.

Beam weapons won't replace missiles. The advantage for missiles is on-board targeting which allows accuracy to improve as the missile nears the target. A missile also carries an explosive charge which allows the missile to be effective as a proximity weapon. The obvious disadvantages are time to reload, logistics, and cost per shot.
The advantage for beam weapons is ability for continuous fire without need to reload. The greater demands for precision ground based targeting would be offset somewhat by ability to sweep the beam over a wider target area. These beam weapons may prove more effective against swarms of smaller drones such as those being observed in Ukraine. If the Israelis can get this to work reliably then it could be a valuable addition to battlefield air defenses.
Directed energy beam weapons have been on the drawing board since the 1980s (or earlier). The prior attempts were hampered by atmospheric/environmental interference (still a significant problem) and targeting capability (which has improved immensely). Those earlier attempts had difficulty overcoming vibration and movement in the weapon mount. New technology to overcome jitters has experienced transformative advancement over the last two decades.
Beam weapons won’t replace missiles?
Correct.
But that not what they are claiming. Rather, this was developed to supplement missiles.
In fact there are several different systems, each having its pros and cons. (That gives defenders more flexibility in defending against different types of threats).

And shown in the recent military parade in China...The LY-1 High Power Laser Weapon.

Named the “LY-1”?
I find it a bit strange that they use a Western name ( and label it) with Western characters rather using a Chinese name & a Chinese alphabet.
While I was watching the parade on TV I noticed that many of the weapons used English letters as well, and wondered about that myself. However I can't find a specific answer using Microsoft BING. If you can get an answer on Google, searching with "Why are English letters used on Chinese weapons" please let me know the answer.
