Anti-Orbit Laser Submarines (2017)
A blog dedicated to helping Science Fiction authors create and discuss worlds where a realistic setting can still serve the fiction.
A or'raser' can be generated by a Free Electron laser or inductive output tubes with an efficiency exceeding 70%.The advantages of a radio-based anti-orbital system is that it allows a submarine to fire upon targets while deep underwater. Although the lens will have to be rather large and heavy to receive a laser beam from a wide variety of angles underwater, and re-focus it in a moving target hundreds of kilometers above, which makes it expensive, it must be considered as an expendable asset when compared to cost and size of a nuclear submarine. At 1000km, its performance is still a respectable 52mm/s through carbon.Spaceship in Children of a Dead Earth scarred by laser strikes.More advanced submarines can get away with smaller lens that are harder to counter-attack and still deal devastating damage to high orbit targets.
