Another potential weapon system for anti-aircraft use is the laser. Although air planners have imagined lasers in combat since <answer>the late 1960s</answer>, only the most modern laser systems are currently reaching what could be considered "experimental usefulness". In particular the Tactical High Energy Laser can be used in the anti-aircraft and anti-missile role. If current developments continue, some[who?] believe it is reasonable to suggest that lasers will play a major role in air defence starting in the next ten years.
When did personnel first start thinking about using lasers in combat?
the late 1960s
