U.S. Air Force Efforts

Last summer, the United States Air Force Life Cycle Management Center and Raytheon Technologies announced the first successful test of the Air Force's first palletized high-energy laser weapon. The tests were conducted during four days of continuous live-fire exercises at White Sands Missile Range in New Mexico.

Known as “H4,” the palletized laser weapon was developed to protect people and assets against short-range aerial threats. It has passed the Air Force’s Test and Assessment plan, which included multiple days of live-fire exercises to acquire, target, track, and destroy drone targets in short-range attack, swarm attack, and long-range threat scenarios.

The H4 is the fourth operational laser weapon system that Raytheon Technologies has delivered to the United States Air Force. It is also the eighth total system the company has delivered to the U.S. Department of Defense (DoD).

Do the Dew

Also known as "directed-energy weapons" (DEWs), these have been seen as a serious force multiplier, which is why so much emphasis has been placed on their development. These have included efforts in High Power Microwave (HPM) and High Energy Laser (HEL) systems.

The U.S. Navy has been working for more than a decade on various efforts to equip warships with laser weapons that could confuse or destroy enemy systems. The service's fiscal year 2023 (FY23) budget request had called for more than $103 million to support half a dozen laser weapon concepts.

It was in August 2022 that Lockheed Martin announced it had delivered to the U.S. Navy a 60+ kW-class high-energy laser with integrated optical dazzler and surveillance (HELIOS). It was the first tactical laser weapon system that could be incorporated into existing ships and provide directed energy capability to the fleet.

Reported to be integrated and scalable by design, the multi-mission HELIOS system will reportedly be able to provide tactically relevant laser weapon system warfighting capability as a key element of layered defense architecture. The HELIOS system could further support long-range intelligence, surveillance, and reconnaissance (ISR) missions.

Lockheed Martin was awarded the Surface Navy Laser Weapon System (SNLWS) Increment 1, known as HELIOS, contract in January 2018 and has made steady progress on this rapid Directed Energy prototype.

Cost Savings on Lasers

Though it could be costly to develop the weapons, in the long-run it would be a truly worthwhile investment.

As the Navy Times further reported, DEWs could help the warships conserve their respective finite munitions supplies while on station. The 60-plus confirmed intercepts of drones and missiles that targeted U.S. Navy warships and commercial vessels in the Red Sea have largely relied on the Standard Missile-2, or SM-2, although service officials have declined to say precisely what has been fired in each engagement.

One of the clear benefits of lasers and other DEWs is the price tag. Rather than expending missiles that cost anywhere from tens of thousands to millions of dollars each to manufacture, a laser depends only on electrical output, which can be generated for less than $1 per shot.
