Why researchers are so interested in laser weapons? The arm race is a race between an improved attacker and an improved defender. Things like Javelin missiles have two-stage tandem warheads that send hypersonic metal beams against the target. The improved weapons require improved counteractions. One of those counteractors is a laser weapon, which can destroy incoming missiles and ammunition over long distances. Laser weapons are the next-generation tools against grenades, drones, and low-flying aircraft. Laser weapons can also cut holes in the ship's hulls and the thing that makes laser weapons so interesting is simple. It gives also small-size crafts the ability to make fatal damage to large ships. If a laser cuts a slit in the ship's bow that kind of damage will be fatal if the ship must run at high speed. The Ukraine war has shown how difficult is to protect targets against drones. Even simple, straight-flying drones are difficult to defend. The drone itself is an easy
