One of the threats to the gas pumping rigs off the Israeli shore is from unmanned air systems armed with explosives.

The Laser Weapon System (LaWS) prototype will be installed on the amphibious transport dock USS Ponce and, in addition to undergoing tests at the theater, will provide operational capabilities against any hostile fast attack craft or unmanned aircraft.

According to Aviation Week , the LaWS has been tested on land, in a desert environment at China Lake and in a maritime environment on San Nicholas Island off California. And last July-August the system was tested at sea for the first time, on the destroyer USS Dewey off San Diego. The system shot down three BQM-174A Dragon target drones in three live firings

For the Gulf deployment, expected to last six months, the LaWS will be installed as a self-defense weapon and integrated with the Ponce’s combat system, including the sensors and operator station for the Phalanx close-in weapon system. Sailors will be trained to operate the system for the deployment, both for testing and to provide an operational capability to defend the ship in the busy Gulf.

Industry teams are already designing more production-representative systems for a follow-on second phase of the Innovative Naval Prototype program. This is expected to use more powerful military-grade solid-state lasers. The goal is to develop a system that can be installed on existing ships, using power margin already available.
