Israeli Lasers and American Defense
(Wall Street Journal) Editorial - Israel's Iron Beam laser air-defense system was declared operational Wednesday after final tests intercepting rockets, mortars and drones. It's an important advance as the West faces new, low-cost threats and a reminder of what strong defense relationships can achieve. The Iron Beam is said to burn or fry targets up to six miles away. Interceptions take seconds, and with a constant energy source, lasers don't run out of ammunition. Laser systems aren't a replacement for conventional air defenses. At present, they have trouble in low-visibility conditions, and electronic components of drones can be hardened to withstand their attacks at long range. Laser systems can, however, be a complement. Israel used a lower-powered version of Iron Beam in combat for the first time in November 2023, shooting down Hizbullah drones. In time, Iron Beam may go airborne and extend its range. The U.S. invested in the system, including $1.2 billion in April 2024. Each U.S. PAC-3 Patriot interceptor costs $3 million. Those add up and could run out against drone swarms in a prolonged war. The Houthis wore out American patience with $2,000 drones that had to be met by million-dollar naval interceptors. If U.S. military aid to Israel can chip away at that problem - in addition to rolling back the power of mutual adversary Iran - all the better.
