The New Nuclear Sub with Laser Weapons

Impressive!

..."Whatever the reason, these lasers won’t be fully operational for at least three years, based on planned upgrades for the Virginia-class photonics mast.

Sea spray and waves also become a bigger obstacle when a weapon is closer to the water’s surface.
