The laser goes from the weapon of tomorrow to the weapon of today as the US Navy announces the completion of its successful deployment of the Office of Naval Research's (ONR) Laser Weapon System (LaWS). The deployment is the first on a US Naval vessel and took place on the USS Ponce (LPD-15) in the Arabian Gulf from September to November of this year.

Developed as part of the ONR's Solid-State Laser-Technology Maturation program, LaWS is part of the US military's effort to develop a cost-effective, combat-ready laser prototype. While LaWS is not the first laser weapon ever to have been deployed, it is the first on a US Naval vessel and is a considerable advance on previous laser weapons.

According to the Navy, LaWS is capable of handling small attack boats, unmanned aerial vehicles (UAV), and other asymmetric targets, and has a wide range of settings, ranging from the ability to "dazzle" people and sensors without destroying them, to being able to disable or destroy targets. It also has the advantages of being able to engage targets at the speed of light, not requiring ammunition, being able to operate so long as power is available, and has a cost-per-round of a about a dollar per shot – which is a considerable saving in an area when munitions can cost thousands or even millions apiece.

According to Rear Adm. Matthew L. Klunder, chief of naval research, this helps to ensure that the US Navy and Marines are never in a "fair fight."

This year's deployment was a joint mission by ONR, Naval Sea Systems Command, Naval Research Laboratory, Naval Surface Warfare Center Dahlgren Division and private industry. During its time at sea, the laser was used against a variety of targets, such as small boats and other moving targets at sea, and also managed to knock a flying Scan Eagle UAV out of the sky.

The Navy says that the LaWS exceeded expectations not only in reliability, but in maintainability as well, and it integrated seamlessly with the Ponce's existing defense systems. In addition, sailors aboard said that it performed flawlessly in all weathers, including high winds, heat and humidity.

The deployment is part of the system's development following demonstrations in 2011 and 2012. The results of this year's deployment will be used to assess the progress of the program and determine future development timeframes. The ONR sees the system as not only applicable for sea duty, but also as an effective defense against airborne and ground-based weapon systems.

"Laser weapons are powerful, affordable and will play a vital role in the future of naval combat operations," says Klunder. "We ran this particular weapon, a prototype, through some extremely tough paces, and it locked on and destroyed the targets we designated with near-instantaneous lethality."

General Dynamics delivers second mobile landing platform to US Navy

mobile landing ship USNS John Glenn (MLP 2)

General Dynamics NASSCO has successfully delivered the second mobile landing platform (MLP) ship, USNS John Glenn (MLP 2), to the US Navy.

The second MLP ship has been named to honour the former US Marine Corps pilot and US senator John Herschel Glenn, who is also the first American astronaut to orbit the Earth.

General Dynamics NASSCO president Fred Harris said: "We are delivering this ship with the quality, innovation and capability needed to support the future missions of the nation's fleet and uniformed men and women around the world."

The 785ft-long MLP is a new class of auxiliary vessel being designed for the US Navy to serve as a floating base for amphibious operations and a transfer point between large ships and small landing craft.

Powered by a twin-screw diesel electric propulsion system integrating four MAN/B&W medium-speed diesel engines, the new MLP ships will enter service with three maritime prepositioning force (MPF) squadrons to support a wide range of missions including humanitarian assistance, disaster relief, amphibious and other combat missions.

The third ship of the class, MLP 3, is currently under construction by NASSCO and will be configured as an afloat forward staging base (AFSB).

MLP 3 is expected to be delivered to the US Navy in the second quarter of 2015.

Separately, the US Navy has placed orders with General Dynamics for maintenance and modernisation of the Virginia-class attack submarine, USS Minnesota (SSN-783).

Under the $57m contract, the company will perform a post-shakedown availability, which consists of maintenance work, repairs, alternations and testing to ensure the submarine is operating at full technical capacity.

Scheduled to be completed in February 2015, work under the contract will be conducted at the Electric Boat shipyard in Groton, US.
