At The Register, Neil McAllister reports on the most recent successful test of the US Navy’s LaWS prototype and plans to deploy the weapons to the Persian Gulf:
The US Navy says it has successfully test-fired a ship-mounted laser weapon, and that it plans to deploy the device to an actual maritime staging area beginning in 2014.
On Monday, the Navy released video and still images showing the somewhat-unimaginatively named Laser Weapon System (LaWS) firing on an unmanned drone, causing the aircraft to burst into flames and plummet from the sky.
Speaking at the Navy League Sea Air Space Exposition at National Harbor, Maryland on Monday, Rear Admiral Matthew Klunder, chief of Naval research, said the device would be deployed to the Persian Gulf, where Iran has been “harassing” US ships with drones and small, fast boats.
“The area we’re going to test this in is a very intensive maritime region of the world,” Klunder told USNI News. “Lots of commerce, lots of ships.”
Klunder said the Navy has field-tested the solid-state laser 12 times so far, and in each case it managed to destroy its target. He added that the weapon also has a nonlethal mode that can generate a “dazzle” effect, which can be used to blind enemy vessels by overwhelming their sensors.
In addition to being effective against small, fast-moving craft, the cannon offers another benefit: its low cost relative to traditional weapons systems. According to The New York Times, firing LaWS costs less than $1 per sustained pulse. Compare that to the cost of a short-range interceptor missile, which the paper estimates run around $1.4m apiece.

120804-N-ZZ999-001 SAN DIEGO, Calif. (Jul. 30, 2012) The Laser Weapon System (LaWS) temporarily installed aboard the guided-missile destroyer USS Dewey (DDG 105) in San Diego, Calif., is a technology demonstrator built by the Naval Sea Systems Command from commercial fiber solid state lasers, utilizing combination methods developed at the Naval Research Laboratory. LaWS can be directed onto targets from the radar track obtained from a MK 15 Phalanx Close-In Weapon system or other targeting source. The Office of Naval Research’s Solid State Laser (SSL) portfolio includes LaWS development and upgrades providing a quick reaction capability for the fleet with an affordable SSL weapon prototype. This capability provides Navy ships a method for Sailors to easily defeat small boat threats and aerial targets without using bullets. (U.S. Navy video by Office of Naval Research/ Released)
