A US Navy warship has successfully tested a new high-energy laser weapon that can destroy aircraft mid-flight, the Navy's Pacific Fleet said in a statement Friday.

Images and videos provided by the Navy show the amphibious transport dock ship USS Portland executing "the first system-level implementation of a high-energy class solid-state laser" to disable an aerial drone aircraft, the statement said.

The images show the laser emanating from the deck of the warship. Short video clips show what appears to be the drone burning.

The Navy did not give a specific location of the laser weapons system demonstrator (LWSD) test, saying only that it occurred in the Pacific on May 16.

The power of the weapon was not disclosed, but a 2018 report from the International Institute for Strategic Studies said it was expected to be a 150-kilowatt laser.

"By conducting advanced at sea tests against UAVs and small crafts, we will gain valuable information on the capabilities of the Solid State Laser Weapons System Demonstrator against potential threats," Capt. Karrey Sanders, commanding officer of Portland, said in the statement.

"With this new advanced capability, we are redefining war at sea for the Navy."

We've been adding to the feds balance sheet in trillions ...

Adding trillions to our national debt ...

But, hey, we can FINALLY shoot down a North Korean plane midflight. Yet, somehow, we just can't afford to absolve millennials of student loans. Its a mystery!

Does the beam diffuse with distance? I think it must

As long as it isn’t cloudy.

Does the beam diffuse with distance? I think it must
I'm guessing about 1.4+/- x diameter of the beam in 40 miles using the proportion given of 1.5 miles diameter in 225,000 miles.
If you know the wave length, use the equations at the end of this post.

Weapons-grade lasers also tend to have a much larger opening, or aperture, which counterintuitively causes the laser beam to spread out less, thus enhancing the beam’s ability to maintain its intensity over longer distances.
Because of the larger aperture, if the missile-killer laser beam is aimed at the moon, the infrared spot it would make on the surface would only be about 1.5 miles across. For comparison, the incredibly dim red dot from your pocket laser pointer would be 8 miles wide once it reached the moon.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
One only needs three rather simple equations for all the calculations done in this article. First, if we assume the laser is optimized so that its spreading angle is at its theoretical minimum, then we can calculate its beam divergence (in radians) using this equation.
(The laser's wavelength)/(π × The laser's aperture)

Then a little bit of geometry will give us the size of the final lit spot at the destination.

π × (Beam divergence in radians × Distance)2

Yes MM II, as a class project in hydrology, I timed how long it took a droplet of water placed on the top curvature of a beautiful butt to reach the pre-developed bushy area in the southern location of the mass..."Time of concentration".

Time of concentration is a concept used in hydrology to measure the response of a watershed to a rain event. It is defined as the time needed for water to flow from the most remote point in a watershed to the watershed outlet.

I suspect atmospheric attenuation would be the biggest limiter in reducing effectiveness together with tracking effective enough to maintain the beam on target at large distances. However, I'm not sure what wavelength this is so perhaps the atmosphere isn't as big a factor as I think it might be.

The equation we used to approximate the distance to the horizon in miles based on the height of eye was to take the square root of the height of eye in feet and multiply it by 1.23. A radar 100 feet above the waterline would provide a horizon distance of 12.3 miles. An incoming cruise missile skimming the surface at 9 feet would provide an additional 3.7 miles to the detection range. A 600 mph missile would provide a shipboard watch stander 96 seconds from detection to impact.

Do you remember Jefferson, Adams, Franklin talking about how one generation passing DEBT to another generation enslaves that generation and is regarded as TAXATION WITHOUT REPRESENTATION, since that generation had no vote or say in the debt?

Anything else rattling around inside that African Ape skull of yours you'd like to share?!?

Better check out what's wrong with that African Ape brain of yours.

Student loans are the student's debt. If the government offers free education....which means the government is paying for it.....then it becomes government debt and taxation without representation.

Correct slykens, I followed up earlier today on Google reading a few experiments concerning atmospheric particles and laser deflection after reading another poster mentioning the same.

pirates and whalers should all be fair game

I understand they have a microwave weapon they use on Pirates, derived from a crowd control device. It impacts the target and makes his skin feel like he’s burning. Non lethal if used briefly, and very effective.
