[Wired] Navy laser sets ship on fire - Page 9

post #81 of 119
If this was Star Wars the title would be "Deathstar laser blows up planet."

Still cool, don't know how effective it would be against another ship though, most ships are metal and don't have their engines exposed...

Would make a great tool for Coast Guard interdiction teams and Anti Piracy squads around the world.

Unfortunately I think they would have to be about right on top of the craft to make it work and would have to set it up like Phalanx systems are set up for targeting and tracking. You wouldn't be able to put something like that onboard a Civilian vessel it would cost too much.

For a technology-minded forum, I'm pretty disappointed in how many users have posted ignorant comments about the laser. To cover a few misconceptions:

i. The vast majority of lasers, particularly military, are not in visible wavelength. This isn't a video game.

ii. "Large laser beams" are also a scientific absurdity. Unless you have an absurdly powerful device, you're just begging for more diffuse.

iii. Mirrors, even incredibly polished astronomy-grade mirrors, would never deflect a military-grade laser.

iv. This is a technology demonstrator, not an actual device.

v. How many other weapons do you know that can hit a mile away, in an exact spot, the same instant you hit a button regardless of wind or position?

vi. Anti-missile, and with increased range, anti-aircraft. How well do you think an aircraft holds up with holes being burnt through the fuel lines in the wings? Or a missile's warhead?

vii. We have much more powerful lasers. The biggest issue is fitting something, reusable, targetable, and effective, on a ship.

Seriously guys, know what you're posting about.

Agree with everything but this...

...since wind is a non issue on light. I doubt that it would pose much of an issue even in the coldest of climates. And position always poses an issue, in order to take out the engines in the Demonstration the unit was mounted out and away from the craft in order to direct the beam clearly at the intended target. But that was mounted TO the craft.

Now try it on two different craft. The surface of the water isn't exactly linear. One craft up other craft down, both crafts down water up. Water being the deciding factor and the height of the targeting craft and how she's sitting in the water. Low or high?

As I said it would take an intricate targeting system(such as which Phalanx operates on) in order to place the beam in the right spot.

Fuel cells on an aircraft are another beast entirely. I don't have the background but I do believe that military aircraft have self sealing wing tanks and their lines aren't like your typical automotive fuel line in that they're not super long. The likelihood of a laser burning through the wing, into a shielded fuel cell and causing engine failure is remote since the system is built with redundancy in mind in order to get the pilot safely back home.

Also keep in mind that the Navy is testing this as a deterrent not(though I'm sure they're considering the option) as an actual weapon. Hmmmm maybe Ronnie Ray Gun was onto something with SDI after all.

I was expecting something along the lines of the destruction of Alderaan.

That wasn't a weapon. It can be but the application that it was tested for was clearly about disabling the craft that is more maneuverable than a Frigate, Light Cruiser or Destroyer to gain the edge in Interdiction enforcement in the drug war. The money confiscated in these types of missions is what paid for it. So let's be honest shall we? It's not meant for killing and it's entirely possible to build something to brick a $3k Evinrude outboard Motor without killing a single person.

Now if they wish to get stupid and draw down on a Ship with a couple hundred Sailors armed to the teeth with .50s pointed in their direction then they deserve the copper jacketed enema they will receive.

The laser would cut through the mirror almost as easily.

It's only a 15 kW laser, a prototype. It will be scaled up at least an order of magnitude before entering active service.

No, it's fairly plausible, if done with independent mirrors.

Mirrors are only reflective in narrow ranges. Unless it reflects all of the light at the exact wavelength of the laser, it's going to fail.
