But apparently that's not enough for the Navy. They want a laser that's bigger. And better. (And presumably badder.) And they want Northrop Grumman (NYSE:

) to build it.
Of course it is not good enough.

Shooting down drones and destroying speed boats is nice...but the real threats are missiles and high performance attack aircraft.

That has always been the goal...and the US Navy will achieve it...you folks watch and see.

They want to...heck I want to see them...

"take out cruise missiles, drones, and manned aircraft at ranges of a few miles."

I imagine, once completed, you will see them on the Burkes, the Ticos, the Zumwalts, the Carriers (particularly the ford Class) and the LHDs and LHAs.

...most of those will also ultimately get some form of the Rail Gun too.

Imagine a Burke armed with two Laser CIWS, a Rail Gun (for surface attack and CIWS), and its compliment of missiles. Same for the Ticos. Same for the Zumwalts.

Imagine a Ford class with 4 x Laser CIWS, 2 x Rail Gun CIWS, 2 x RAM Missiles, and 2 x ESSM launchers.

That is the type of thing the US NAvy is ultimately looking forward to.

more lethal and efficient will include experiments with new uses for missiles and application of new rail gun technology to smaller weapons systems, the service's director of surface warfare said Tuesday.

Amid a rapidly changing global environment in which Navy technology was fast being outpaced, Read Adm. Peter Fanta said the service was adopting a philosophy of increased lethality and "three ways to kill everything."

"I realize that might not be the nicest way to talk about things, but folks, our job is to kill people and break their toys," he told an audience at the annual Surface Navy Association symposium near Washington, D.C. "There's nothing else in the world that matters."

Among projects in the works for the Navy is the development of new gun rounds, including the possibility of a smaller version of the electromagnetic projectile launching technology used by the rail gun weapon now in development. The rail gun, which can hurl a projectile at well over 5,000 miles per hour, is being evaluated for possible mounting on a Zumwalt-class destroyer by the mid-2020s.

"When we take that projectile with the rail gun, why not make it small enough to put in a five-inch round ... with a couple of hundred five-inch rounds that now can shoot something as far, almost as accurately as a rail gun?" Fanta suggested.

While he said some of Navy's testing and evaluation efforts were classified, Fanta said the service was looking at new rounds for existing weapons in the fleet that were based on "leap-ahead technologies" such as the rail gun.

"We're learning to build how we're operating, how we're testing and we're developing those capabilities in the rail gun and we're expanding that to the rest of the fleet," he said. "It would be a shame if we took all that science and all that engineering and just left it for the science project that will become operational in the future instead of tacking as much as we can onto the current weapon."

And development of new rounds was just one line of effort in a push to get more out of the Navy's weapons.

Fanta also reaffirmed plans to install an over-the-horizon surface-to-surface missile on a

later this year, an effort he first announced last October. He referred to an early 2015 experiment in which a Tomahawk cruise missile launched from a

hit a moving target at sea. Why, he asked, could the system not be adapted to find moving targets on land as well?

"I got it, it's not perfect, it doesn't meet the ideal ... [but] let's change the payloads, let's change the sensors, we've done this already," Fanta said.

"This is not aspirational," he added. "This is operational."

Rheinmetall and the German Bundewehr have successfully tested a high-energy laser effector installed on a German warship operating on the high seas. To carry out the test, Rheinmetall mounted a 10-kilowatt high-energy laser (HEL) effector on a MLG 27 light naval gun.

This is very nice to see. Will give good testing.

By comparison, this 10 Kw laser is not as powerful as the 40 Kw laser the USS has been teting aboard the USS Ponce for some time now.

But even then, at 40 Kw, it is only able to target drones, small aircraft and small boats effectively. It will need a lot more power to take down larger military aircraft, missiles, or damage a ship. And the US Navy is developing such lasers.
 
not too specific but
ONR Winter to Congress: Navy Making Progress on Developing High-Energy Laser Weapons
High-energy laser weapons “are moving forward in marked progress,” the director of the Office of Naval Research told the House Armed Services Emerging Threats and Capabilities subcommittee Wednesday.

Rear Adm. Mathias Winter said there is solid cooperation among the services and with the Department of Defense without duplication in work in this arena.

But where needed, as in directed-energy underwater, “there are challenges” unique to the Navy that the service is addressing.

In his opening statement, he said it was “essential to tie the technical to tactical to strategic” in naval research. Using high-energy laser weapons as an example, Winter cited the sea service’s drive to increase power from 30 kilowatts to 150 kilowatts in the weapons being developed for the Navy and the Marine Corps.

The Navy’s and the Defense Advanced Research Projects Agency work in unmanned underwater and surface maritime vehicles drew the panel’s attention. DARPA Director Arati Prabhakar said the agency was working on the vehicle that would operate in the ocean “without a single sailor aboard.” Winter said earlier in the hearing the Navy would sail its large-displacement unmanned underwater vehicle from San Diego to San Francisco this year.

Stephen Welby, assistant secretary of Defense for research and engineering, defined all those efforts as part of the Pentagon’s “third offset” strategy of maintaining an asymmetric advantage over potential adversaries.

While the third offset strategy is not “a thing,” but “an ambition” as to ways the United States will fight in the future, he said the idea is “how we shift . . . the playing field . . . to where the United States has a dominant, enduring advantage” as it had with tactical nuclear weapons and stealth in the past.

Looking ahead 20 years, Welby said to expect a “fundamental change from baby steps” to new capabilities in unmanned vehicles and their autonomy.

Winter said with regards to autonomy “we are seeing it in its infancy now.” He also looked to “brain-based learning and how we can model that” and cognitive artificial intelligence as within future reach.

Prabhakar predicted “a fundamental shift in how we understand social behavior” and as a result of that how we understand conflict.

In all those areas—including “biology as a technology,” the future of manufacturing or steps to provide endless energy—Welby said that as a department, “we want to be able to surf that wave.”

Laser Weapons Ready for Use Today, Lockheed Executives Say
?
For years, the Pentagon has pursued the dream of directed energy weaponry — laser weapons that could defeat a foe for pennies when compared with the expensive kinetic weapons the department relies on. And for years, the technology proved to be elusive.

But the time has finally come where those weapons are capable of being fielded, according to a trio of Lockheed Martin executives who work on the development of the company’s laser arsenal.

“The technologies now exist,” said Paul Shattuck, company director for Directed Energy Systems. “They can be packaged into a size, weight, power and thermal which can be fit onto relevant tactical platforms, whether it’s a ship, whether it’s a ground vehicle or whether it’s an airborne platform.

“So everything exists today,” he said, “it’s just a question of the desire and when is that going to occur.”

Added Daniel Miller, Senior Fellow for Air Vehicle Science and Systems with Lockheed’s Skunk Works division, “the question is moving from, ‘Do we have the devices?’ to ‘How quickly can we integrate them on the platform?’ The question has changed dramatically on the last decade.”

In essence, it’s no longer a technological problem to make laser weapons work. It’s one of integration at the service level.

Asked flatly if the services came to them tomorrow and asked for a laser weapon in the 30 KW range to be delivered, the two men, along with Robert Afzal, a senior fellow with Laser and Sensor Systems, agreed they could produce a viable weapon for fielding.

That doesn’t mean that giant city-melting lasers are on their way. Right now, the weapons are limited to the 15-30 KW scale; going much further requires figuring out how to deal with atmospheric interference, an issue which becomes more complicated with weapons mounted on airborne systems.

But a 30 KW weapon can still bore a hole through a two inch piece of steel in seconds, said Shattuck, which is enough to disable an incoming rocket or hit the engine of a pickup truck. For the Pentagon, that is particularly key, as it has openly talked about the costs associated with using kinetic weapons to attack small trucks operated by the Islamic State group, commonly known as ISIS or ISIL.

The company has already proven the capabilities of a 30KW weapon with its Athena demonstrator, which last year conducted a series of tests on small unmanned systems from over a mile away. The weapon was able to identify and disable those systems with great accuracy, down to taking out just a leg of a system or blinding its camera.

A number of advancements in recent years have allowed the company to move forward with laser technology, but the biggest one is the movement in fiber-laser technology, which is largely driven from developments in the commercial sector.

The men described the technology as similar to a rack of servers. Once you figure out how to connect them all, you can add more power by adding another server. The same is true for the laser weapons: you add more power slots into the rack and increase its power.

So while the 30 KW weapons may be the ones that are deliverable now, scaling up is more a question of figuring out details than developing a wholescale new technology.

Lockheed is on track to deliver a 60 KW laser for the Army by the end of the year, known as the RELY program, said Afzal, saying “we’re underway. So we’re building hardware right now and we’re beginning the integration.”

Meanwhile, the Navy is using an advanced laser weapon aboard the Afloat Forward Staging Base Ponce, which has been deployed to the Gulf.

The maximum range of HVP is only about 40 % of EMRG. Specifically against cruise missiles, HVP fired from 5 inch guns is only effective up to 10 nm as opposed to EMRG rounds of up to 40 nm (source: CSBA Winning the salvo competition page 23). The plus side with HVP is the wide availability of 5 inch guns.
