Raygun dreadnought project reports 'remarkable breakthrough'

The Regster said:
US Navy boffins say they have achieved a major milestone in their quest to build an invincible raygun battleship.

The breakthrough comes in the Free Electron Laser (FEL) project, intended to produce an electrically powered, megawatt-range laser able to sweep the skies of pesky aircraft, hypersonic shipkiller missiles etc. Specifically, the Office of Naval Research reports that its boffins working at the Los Alamos National Lab in New Mexico have demonstrated "an injector capable of producing the electrons needed to generate megawatt-class laser beams".

Not long before we have Command and Conquer style uplink particle canons and tesler coils :D

Only issue with the FEL.. is it's 14 mile range to the horizon (or shorter in heavy seas). Just wait for the hypersonic missile that can cover the 14 miles quicker than the system can bring on line and target...

Just waiting for the combination FEL & rail gun underwater weapon. The laser vaporises the water and the railgun puts a high speed shell down the vapour tunnel to the target..

One word. Aegis. The ship mounting the laser won't have to detect the target itself, as the Aegis combat system would be fusing sensor data from other ships throughout the battlegroup, allied assets, satellites etc. Imagine the presence of a carrier perhaps, and the E-2C/D Hawkewe AWACS that would come with it. I'd imagine the laser would be online, orientated towards the target and prepared to fire long before the missile came in range.

I thought that, but you could have a mirror in geostationary orbit above the laser, laser shoots straight skywards, mirror directs beam over a huge area.

They use satellites as well as radar, so they can see them coming

i'm not overly sure on the feasibility of that, whether the laser would reach, due to their height "One disadvantage of geostationary satellites is a result of their high altitude: radio signals take approximately 0.25s to reach and return from the satellite..."... Also surely wouldn't the geostationary satellite only be able to protect a certain area, tell me if i'm wrong i havnt studied satellite physics in a while...
 
Eh? My point was that a laser fired from the ground has only got a limited range (i.e. it's straight line seeing distance).

Doesn't matter about the range of the actual laser as the detecting and aiming would be done before the target gets within range.

A missile would have to be fired over the horizon as nothing would get closer than that to the fleet. It would be easily detected as soon as it was fired. The laser would then be powered up, aimed and be ready to fire, probably within seconds and then would simply wait for it to come into range. Even traveling at 5000mph, which no current anti-ship missile does, it would take a missile 7-10 seconds to travel the range of the laser, more than enough time for it to be shot down.
 
How do you think they do it now?

A laser is faster than a rocket

The FEL would take some time to power up. Not as long as current lasers I suspect but still it would take time.

I like the satellite bounce idea, however the atmosphere and weather within it could prevent this. (although part of the spread spectrum for the FEL is probably for all-weather use and the other half is to make it difficult to block/reflect.

Doesn't invoke quite the same BFG CAABOOM smile that the gatlings have (or if looked like a starwars pulse cannon).

The US will miniaturise this and put it into a Hercules for Spooky v2...

Aren't some of those ships nuclear powered? I'm sure they could just leave it on standby mode, it's not like the batteries are going to run out.
