Israel’s use of air-launched ballistic missiles (ALBMs) in its October 26 airstrikes on Iranian missile factories and air defenses has highlighted the potential of these weapons, drawing interest from defense strategists worldwide. The strikes, carried out in three waves by the Israel Defense Forces (IDF), targeted multiple sites in Iran, including buildings reportedly tied to Iran’s nuclear program. Israel’s use of the Israel Aerospace Industries Rampage missile, a high-speed ALBM, demonstrated the advantages of ALBMs for penetrating dense air defense systems with greater speed and accuracy than traditional cruise missiles.
Experts say the success of these strikes could spur interest among other countries. According to Jeffrey Lewis, director of the East Asia Nonproliferation Program at the Middlebury Institute, the main advantage of ALBMs over air-launched cruise missiles (ALCMs) is their ability to reach targets at high speed, making them harder for anti-aircraft systems to intercept. In contrast, cruise missiles, which fly at lower altitudes and slower speeds, are easier for integrated air defenses to target.
This tactical flexibility makes ALBMs particularly valuable for strategic strikes. Unlike ground-launched ballistic missiles, which are restricted to fixed locations, ALBMs can be launched from aircraft, enabling them to approach from various directions and complicating defensive response. Uzi Rubin, a missile defense expert at the Jerusalem Institute for Strategy and Security, explains that ALBMs are harder to intercept because “they can come from any direction, complicating the task of defending against them.”
Iranian missile defense networks include multiple anti-aircraft systems, yet they struggled to counter Israel’s high-speed, precise strikes. However, ALBMs are not without vulnerabilities. In the Ukraine conflict, for example, U.S.-made Patriot PAC-3 systems have successfully intercepted Russian Kinzhal missiles, illustrating that ALBMs can still be countered by advanced air defense systems.
Though the U.S. and U.K. tested ALBMs during the Cold War, neither country currently deploys them. The U.S. Air Force recently halted funding for its hypersonic AGM-183 ALBM project, choosing to focus instead on its arsenal of cruise missiles and other long-range strike capabilities. Defense experts suggest that many nations with access to rocket and guidance technology could feasibly develop ALBMs by repurposing existing technology, thus adding a versatile and powerful option to their military arsenals.
The IRD’s use of ALBMs against heavily defended Iranian targets has reasserted the strategic value of these weapons, potentially prompting other nations to reconsider their reliance on cruise missiles in favor of ALBMs for rapid, high-precision strike capabilities.
