Northrop to Demonstrate Laser Boat Killer

Barely had I blogged on the US Navy's idea using multi-target laser designators to rain Hellfires down on swarming small boats than the service awards Northrop Grumman a contract to demonstrate its other solution to the threat: a high-energy laser.

Northrop has been awarded a $98 million contract for the Office Of Naval Research's Maritime Laser Demonstration (MLD) program, which aims for the at-sea demonstration of a laser weapon mature enough to go straight into development. The demonstration phase is expected to last just 12-18 months.

One of two teams on the Joint High Power Solid-State Laser (JHPSSL) program, Northrop in March beat the goal of demonstrating 100kW laser power in the laboratory. The MLD prototype is to be in the "tens of kilowatts" class, and could be built up from Northrop's Firestrike 15kW laser modules produced using JHPSSL slab laser technology.

Lasers on warships makes a lot more sense than on aircraft. I hope it works. With all the work being done with using the AESA radar to disable anti aircraft missiles and scramble electronics using aerial electronic attack, I've been wondering why that hasn't been leveraged to both the naval and land warfare regimes.

Sounds like a worthwhile idea, but I've got questions about using it in a maritime environment. Lasers are attenuated by moisture. A laser on a ship deck attacking a small boat on the water would be operating directly through the layer of sea spray and dense moisture in the few feet directly above the surface. The very warm waters and humid atmosphere of the Persian Gulf, along with the prevalent haze, dust, and smoke would seem to make for a very difficuly operating environment for a weaponized laser.

Agree that lasers on warships make a lot more sense than on aircraft but I have to question whether or not the current class of ships in the USN have enough headroom in power production capabilities to accommodate laser weaponry.

DDG-51 (Arleigh Burke) class are outta gas on power. 1980s design that has used up it's power heasdroom on 1990s radar and 2000s computers.
The DDG-1000 (Zumwalt) class has a TON of power headroom, specifically designed-in for weapons of this class, as well as for the rail gun planned for the first of the series.
Folks may love those DDG-51s, but the design is at end of life, and the cost difference is not as huge as it has been alleged. Time to build the last one and move on to a new design - maybe even the DDG-10000 with rockets vice rail gun. Watch this space.

Whoops, that penultimate sentence was supposed to read:

I totally agree with CT Woods, it is time to move on to the DDG-1000. The argument that it isn't equipped to take on the ABM mission has been shown to be ill-informed.

Plus as CT said we need to start moving on to railguns and as the article points out DEW's. Power will obviously be an issue so we're shortchanging our future by relying on the DDG-51.

As for Northrop, way to go guys! Hopefully you are working hard also on free electron lasers, which if I'm not mistaken won't be held hostage to weather and other environmental factors as a conventional laser.

Speed of light weaponry is the future. In theory a man holding a laser rifle could shoot down a airplane or missile with effective zero time of flight.

No doubt some idiot bureaucrat will decide lasers are inhumane and ban them in the USN.
