Weekly insights and analysis on the latest developments in military technology, strategy, and foreign policy.

Members of Congress are moving to push the U.S. Navy to develop a containerized version of its High-Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) system. Containerized designs could help accelerate the service’s fielding of laser directed energy weapons on a wider array of ships, providing added layers of close-in defense. The Navy has already been experimenting with palletized designs as part of its larger laser development efforts, which have faced continued hurdles in recent years.

An early draft of the annual defense policy bill, or National Defense Authorization Act (NDAA), for the 2027 Fiscal Year, would authorize the addition of $5 million to the Navy’s budget for work on a containerized HELIOS. It would also add $2.5 million for a “Containerized Maritime High Energy Laser Weapon System,” which does not otherwise appear to be mentioned, at least by that name, in the service’s proposed budget for the 2027 Fiscal Year. The House Armed Services Committee released this draft NDAA earlier this week.

The Navy’s proposed budget for the next fiscal cycle does already include a request for $75.6 million for a separate Joint Laser Weapon System (JLWS) effort. The development of a containerized 150-kilowatt-class laser directed energy weapon, along with work toward 300 and 500-kilowatt-class designs, are part of the stated plans for JLWS. It’s unclear whether the Maritime High Energy Laser Weapon System mentioned in the draft NDAA is related to JLWS.

HELIOS, which the Navy has also designated Mk 5 Mod 0, is a 60-kilowatt-class laser directed energy weapon. At that power level, it is able to destroy or at least damage certain targets, such as drones or small boats, a capability that has now been demonstrated in multiple tests. There has been talk in the past about scaling HELIOS’s power rating up to 150 kilowatts.

Currently, the Navy only has one HELIOS laser, installed on the Arleigh Burke class destroyer USS Preble. Despite integration on an operational warship, the service describes this system as a “Non-Program of Record (POR) Research & Development (R&D) asset” in its most recent budget request.

As an aside, another laser system, the Optical Dazzling Interdictor, Navy (ODIN), is currently found on seven other Arleigh Burke class destroyers. An eighth example was integrated on the USS Kidd, but has been temporarily removed while that ship is completing a two-year maintenance availability. That ODIN system is currently being used for land-based training at the Naval Surface Warfare Center, Port Hueneme Division, in California. Designed as a “dazzler,” ODIN is lower-powered than HELIOS, and is intended to blind or confuse electro-optical and/or imaging infrared systems, including seekers on incoming munitions, sending them off course rather than shooting them down.

As noted, HELIOS offers demonstrated capability now, and a containerized version is something the Navy might be able to field more widely in the near-term. This, in turn, could help provide a bridge to future developments under JLWS. Containerized systems, as well as palletized ones, inherently offer valuable flexibility, especially in a maritime context. Integration can be more readily achieved on a broad array of ships – including carriers, amphibious warfare ships, sea base-type vessels, and sealift ships, as well as certain surface combatants – as long as there is sufficient deck space and available power.

In April, the Navy disclosed a test of a palletized version of AeroVironment LOCUST laser counter-drone system on the Nimitz class aircraft carrier USS George H.W. Bush, underscoring exactly this kind of flexibility. For that test, AeroVironment leveraged a palletized configuration of LOCUST it had already developed for the U.S. Army. However, various changes were made to adapt it to shipboard use, including “hardened electronics for salt fog, humidity, vibration, and long deployments” and the addition of “stabilization hardware to manage ship motion,” according to a company press release.

Counter-drone defense has emerged as a critical priority for the Navy, both at sea and on land. This has only been underscored by experience gained during the latest conflict with Iran, as well as operations in and around the Red Sea in recent years. The service has already been adding counter-drone systems that use physical interceptors as their effectors to an ever larger number of ships, something TWZ has been closely tracking.

When it comes to a containerized version of HELIOS, which could also be used to bolster defenses ashore, would benefit from having been developed for maritime use from the start. It might still be less hardened against environmental conditions, as well as battle damage, than its more deeply integrated counterpart on the USS Preble. There are also questions about how the system might be integrated onto the host ship and its combat system, if it has one at all.

In general, as long as there is sufficient power and cooling capacity, laser directed energy weapons like HELIOS offer essentially unlimited magazine depth. This offers cost benefits, especially when compared to employing traditional surface-to-air interceptors. As one comparative example, the latest versions of the RIM-116 Rolling Airframe Missile (RAM), which many Navy ships are armed for point defense, have unit costs in the $1 million range. All of this could also help in addressing long-standing concerns about the sufficiency of stockpiles of critical anti-air interceptors (as well as other munitions), and the ability to readily replenish those inventories, which have only been reinforced by the latest conflict with Iran.

Laser directed energy weapons do also have limitations, especially when employed in the maritime domain, as TWZ has highlighted in the past:

“A single laser can only engage one target at once. As the beam gets further away from the source, its power also drops, just as a result of it having to propagate through the atmosphere. This can be further compounded by the weather and other environmental factors like smoke and dust. More power is then needed to produce suitable effects at appreciable distances. Adaptive optics are used to help overcome atmospheric distortion to a degree. Altogether, laser directed energy weapons generally remain relatively short-range systems.”

“In addition, laser directed energy weapons, especially sensitive optics, present inherent reliability challenges for use in real-world military operations. Shipboard use adds rough sea states and saltwater exposure to the equation. There is also the matter of needing to keep everything properly cooled, which creates additional power generation and other demands.”

Overall, the Navy’s current top leadership is already very supportive of containerized systems and directed energy weapons, including both lasers and high-power microwave types. In March, Chief of Naval Operations (CNO) Adm. Daryl Caudle, the service’s top officer, unveiled a formal Containerized Capability Campaign.

“From towed-array-systems, to drone swarms, to electronic attack systems, to high-powered lasers … I want to containerize everything,” Caudle said at the annual McAleese Defense Programs Conference in March. “Tailored capabilities give our combatant commanders something they value above all else: options.”

Containerized systems are particularly central to the Navy’s current vision for future fleets of USVs, as well as its new FF(X) frigates.

Laser directed energy weapons are also central to the current plan for the Navy’s future Trump class battleships, but they are expected to be deeply integrated into that design rather than containerized. Adm. Caudle has been outspoken more broadly in his view that laser-directed energy weapons are key to bolstering close-in defenses on his service’s warships going forward, including against the growing threat posed by drones.

“My thesis research at [the] Naval Post Graduate School was on directed energy and nuclear weapons,” the CNO told TWZ and other outlets at a roundtable at the Surface Navy Association’s (SNA) annual symposium in January. “This is my goal, if it’s in line of sight of a ship, that the first solution that we’re using is directed energy.”

In particular, “point defense needs to shift to directed energy,” Caudle added at that time. “It has an infinite magazine.”

Even before assuming his current role as CNO, Caudle has been a vocal supporter of Navy directed energy weapon developments. At the same time, as mentioned, the service has faced continued stumbling blocks to more widespread fielding of these capabilities. This is, in many ways, reflected just in HELIOS, which remains a largely experimental effort despite years of testing and previous talk about expanding it into a broader operational capability. The Navy has integrated other one-off lasers onto other ships in the past. This includes the Laser Weapon System Demonstrator Mk 2 Mod 0 installed for a time on the San Antonio class amphibous warfare ship USS Portland, which is seen being tested in this video below.

Several U.S. Air Force and Army laser directed energy programs have also been realigned, curtailed, or outright cancelled in recent years due to technical hurdles and other factors.

Despite it adding funding for containerized system development, the draft NDAA that the House Armed Services Committee also proposes to cut $5 million from the Navy’s Directed Energy and Electric Weapon Systems line item due to what it simply describes as “unjustified growth.” The bill is also very likely to change in substantial ways in the coming weeks and months before it is ever put to a full vote, let alone sent to President Trump’s desk.

Whether or not the extra funding for a containerized version of HELIOS, or the Maritime High Energy Laser Weapon System, comes across in the end, the Navy is already heavily committed to new developments in this arena despite the continued challenges.
