The German navy is building a laser cannon

Germany is planning to install a laser cannon on its warships.

A K-130 class corvette next year will receive a prototype high-energy laser weapons system, or HELWS, for a two-year demonstration, according to German media and European defense contractor MBDA, whose Rheinmetall subsidiary will build the device.

"The HELWS demonstrator for this opportunity will be optimized for the counter-unmanned aerial system (CUAS) threat spectrum, including drones, mini-drones and micro-drones," MBDA spokesman Günter Abel told the National Interest.

Germany's Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support, or BBAAINBw, is expected to release a statement of work and a request for proposal later this year.

"The German Navy requirement provides for the integration of a HELWS on a Germany Navy K130 Braunschweig-class corvette in the 2020-2021 timeframe, and includes a series of engagements trials against an as yet unspecified target set," said Abel. "This will be a 10-kilowatt to 20-kilowatt laser effector, so not yet optimized to engage missile threats; however, the target catalogue will ultimately be defined by the German customer."

In 2016, Rheinmetall tested a Rheinmetall installed a 10-kilowatt laser fitted into a turret of a German warship, but it was only used to track targets.

"In principle all the functionalities and technologies of the MBDA Germany HELWS demonstrator are now proven, and the next step towards a laser product is really driven by the German customer. The priority for us now is to get ready so that we can offer a real integrated and more robust demonstrator to the German Navy."

The Bundeswehr wants to first develop lasers for warships, and then land-based lasers for missions such as missile and drone defense of bases, according to German newspaper Die Welt.

"Laser weapons can also be expected in Bundeswehr vehicles for years, according to the experts, but with a performance lower than the laser of the ship. MBDA also sees an opportunity to use laser weapons in containers to protect ships in ports."

Interestingly, Die Welt noted that "a German laser weapon would have the advantage that it does not require US technology. And, therefore, the export would not depend on the consent of the United States."

Germany isn't the only European nation working on laser cannon. France opened a laboratory this year to develop laser weapons, while Britain is developing its Dragonfire laser (MBDA is also involved in both the French and British projects). Meanwhile, the U.S., Russia, China and Israel are among the other nations busily devising combat lasers.

The U.S. Army plans to field Stryker armored vehicles armed with 50-kilowatt lasers by 2023, while in 2017, the U.S. Navy deployed the amphibious transport USS Ponce – armed with a laser cannon – to the Persian Gulf.

While there seems to be a great deal of optimism that laser weapons have become viable, there are still some question marks. Combat lasers have the advantage of a weapon whose destructive effects travel at the speed of light, as well as having an ammunition supply that isn't limited by how many shells can be stored in a ship's magazines.

However, lasers do devour electricity on ships whose electrical generation capacities often seem taxed by a profusion of energy-hungry systems. A laser must also "dwell" on a target for a sufficiently long period – perhaps a few seconds – to inflict damage.

A Marine wanted for killing his mother's boyfriend reportedly escaped police by hiding inside an RV they'd spent hours searching before towing it to a parking lot, where he escaped under the cover of darkness.

It wasn't until more than two weeks later authorities finally caught up to Michael Brown at his mom's home, which was the scene of the crime.

Brown stuffed himself into a tight spot in his camper during an hours-long search of the vehicle on Nov. 10, according to NBC affiliate WSLS in Virginia. A day earlier, cops said Brown fatally shot his mother's boyfriend, Rodney Brown. The AWOL Marine remained on the lam until Nov. 27, where he was finally apprehended without incident.

No motive is yet known for last week's Pearl Harbor Naval Shipyard shooting tragedy, which appears to have been a random act of violence in which the sailor who fatally shot two civilian workers and himself did not know them and did not plan his actions ahead of time, shipyard commander Capt. Greg Burton said in an "All Hands" message sent out Friday.

Machinist's Mate Auxiliary Fireman Gabriel Antonio Romero of San Antonio, an armed watch-stander on the attack submarine USS Columbia, shot three civilian workers Dec. 4 and then turned a gun on himself while the sub rested in dry dock 2 for a major overhaul, the Navy said.

"The investigation continues, but there is currently no known motive and no information to indicate the sailor knew any of the victims," Burton said.

SEOUL (Reuters) - North Korea said it had successfully conducted another test at a satellite launch site, the latest in a string of developments aimed at "restraining and overpowering the nuclear threat of the U.S.", state news agency KCNA reported on Saturday.

The test was conducted on Friday at the Sohae satellite launch site, KCNA said, citing a spokesman for North Korea's Academy of Defence Science, without specifying what sort of testing occurred.

Since the Washington Post first published the "Afghanistan papers," I have been reminded of a scene from "Apocalypse Now Redux" in which Army Col. Walter Kurtz reads to the soldier assigned to kill him two Time magazine articles showing how the American people had been lied to about Vietnam by both the Lyndon Johnson and Richard Nixon administrations.

In one of the articles, a British counterinsurgency expert tells Nixon that "things felt much better and smelled much better" during his visit to Vietnam.

"How do they smell to you, soldier?" Kurtz asks.

WASHINGTON (Reuters) - Erik Prince, the controversial private security executive and prominent supporter of U.S. President Donald Trump, made a secret visit to Venezuela last month and met Vice President Delcy Rodriguez, one of socialist leader Nicolas Maduro's closest and most outspoken allies, according to five sources familiar with the matter.
