>>64662968Looks like a coil gun, not a laser weapon. Looks like it probably shoots something metal that in turn propels the 'arrowhead' with its own momentum gained from the barrel coils.

>>64662968actually anon that's a super cool concept called laser propulsion. Scott Manlet has a video on it. The projectile you've depicted looks exactly like a side cut of videorel https://youtu.be/FJG6zGLar30It works kinda like solar sails, photons are launched at the craft and hit it, transferring kinetic energy.
>>64663337Looks like the laser is intended to ablate material off the rear of the projectile to use as reaction mass. Better have a steady hand.
