>>509989641 anti-satellite weapon. Probably impractical for ICBMs as they wouldn't have fragile guiding systems exposed like classic missiles.
It would probably be impractical to generate in space the huge power needed, so those weapons would have major drawbacks like idk huge reload times. Laser is very useful for comms though.

A useful case could be defensive antisatellite, to counter e.g. Russian spying sats that go lurking from sat to sat.
