The U.S. Navy has taken delivery of its first operational HELIOS (High Energy Laser with Integrated Optical-dazzler and Surveillance) laser system. The Lockheed-designed laser was installed aboard a San Diego-based destroyer earlier this year, and the company describes it as "the first tactical laser weapon system to be integrated into existing ships and provide directed energy capability to the fleet."

The first shipboard HELIOS laser is fitted to USS Preble, an Arleigh Burke Flight IIA destroyer. Lockheed emphasizes that it is integrated with the Preble's Aegis fire-control system, the same platform used to guide and control all of the other weapons systems on board. The laser could be fitted on other large platforms as well, including carriers or large amphibs.

The initial task for HELIOS is to defeat aerial drones and fast-attack craft. The laser's deep magazine, high accuracy and low cost per round make it an ideal technology for destroying small targets. In the future, the Navy and Lockheed hope to field a version that could be used to take out anti-ship cruise missiles as well. 

“This is a transformational new weapon system. Laser weapon systems are no longer years away; they’re here now," said Hamid Salim, a VP for advanced weapons systems at Lockheed.

HELIOS has an intermediate capacity of about 60 kW of power, reportedly upgradeable to 120 kW. This is in between the low-power ODIN optical dazzler laser fielded by the destroyer USS Stockdale and the powerful 150 kW Laser Weapons System Demonstrator (LWSD) aboard the amphib USS Portland. 

The U.S. Navy has been experimenting with solid-state lasers at sea for nearly a decade. A  lower-power laser, the 30 kw LaWS prototype, reportedly performed well in testing aboard the USS Ponce in 2014-15 but exited service when the vessel was decommissioned.

Faced with increasingly sophisticated near-peer competitors on the high seas, the Navy is ramping up laser weapons testing, including the commissioning of a new R&D facility and test range at Point Mugu, California. A ribbon-cutting ceremony for the new facility was held on December 3, marking the end of a fast-pace two-year construction timeline. Officials described the need for its development as an urgent matter.

The German government announced plans for its fifth Floating Storage Regasification Unit (FSRU) as part of the effort to replace the gas that it previously imported from Russia. Texas-based Excelerate Energy signed an agreement with ENGIE, which is responsible for chartering the FSRU on behalf of the German Federal Government. It will be located at the port of Wilhelmshaven with Tree Energy Solutions (TES) responsible for the development and operation of the FSRU. The fifth FSRU arranged by the government,...

When it comes to autonomous shipping, grandiose visions of fully unmanned vessels sailing the world's oceans and ports are often painted. However, the truth is there are still a host of hurdles to be jumped before we can reach that utopian vision. According to a recent report from Wärtsilä, these include the lack of compelling business cases, an agreed regulatory framework and uncertainty over whether fully unmanned vessels are even desirable.  That raises a very pertinent point, which is the...

. . . [Captain] Fraser opposed an Assistant Secretary of the Treasury, and this official’s hostility proved fatal to the Captain’s long career: by an arbitrary abuse of power, the administration in 1856 revoked his commission summarily. Both indefensible and stupid, this action resulted wholly from personal animosity and cost the government one of the most far-sighted and loyal men who ever sailed in the Revenue-Marine.    - Stephen Evans, The United States...
