The Free Electron Laser and the Electromagnetic Railgun are experimental weapons that the Navy hope will one day burn missiles careening toward their ships out of the sky and fire bullets at hypersonic speeds at targets thousands of miles away. Neither will be ready until at least the 2020s, the Navy estimates. But the Senate Armed Services Committee has a better delivery date in mind: never.
Yes, these are both long term research projects, but keeping ahead of key technology is important for the US in the long run. I would rather see the military spend money on fundamental technology then a lot of other projects the military wastes money on.
