Israel will begin equipping commercial aircraft with lasers to deflect incoming missiles. The C-MUSIC (Commercial MUlti-Spectral Infrared Countermeasure) system uses infrared sensors to automatically detect missiles fired towards the plane. A laser is then aimed at the missile’s navigation system to deflect it off course where it will explode and not harm the aircraft.

The system was developed after a 2002 incident in Kenya where terrorists fired two surface-to-air missiles at an Israeli charter plane carrying more than 250 passengers; the missiles missed their target. C-MUSIC will be added to all El Al aircraft. In addition, the developer Elbit Systems has contracts with other countries besides Israel.

After 16 years and $5 billion in development, the U.S. Air Force’s Airborne Laser Testbed (ABL) program has been shut down. An entire Boeing 747 was needed to house the chemical oxygen iodine gas laser. The COIL laser generates megawatts of power, enough to damage missile skins thus causing the missile to disintegrate. In 2010 the ABL was used against solid- and liquid-fueled rockets in tests.

A key reason for the ABL shutdown was the cost of the project versus the projected military returns. Another reason is that the Missile Defense Agency is looking to a new generation of laser systems with “much denser capacity or greater power lasers in smaller packages and operating at much higher altitudes.” Unmanned aerial vehicles would be an ideal platform. The MDA’s director said antimissile drones using solid-state lasers could be a reality by 2020.

Commentary from LaserPointerSafety.com: We included this story because people sometimes wonder if lasers aimed from the ground can damage an aircraft’s airframe. The short answer is “no”. It would take a system similar to the $5 billion ABL. However, the Missile Defense Agency is now indicating that military-developed solid-state lasers may be able to cause enough damage to down a missile -- or aircraft -- within this decade (the 2010s).

While it is unlikely that non-state groups could deploy such a device, it is more of a possibility than independently developing an ABL-like COIL gas laser. For the foreseeable future, the threat to aircraft remains the visual impairment caused by bright laser light, and to a lesser degree, the possibility of causing retinal lesion eye injuries.
