The U.S. Navy has disclosed the test of an AeroVironment LOCUST laser counter-drone system, which has been in the news recently, aboard the Nimitz class aircraft carrier USS George H.W. Bush. As far as TWZ is aware, this looks to be the first time a laser weapon has been fitted to a carrier. Earlier this year, Chief of Naval Operations Adm. Daryl Caudle, the Navy’s top officer, said his goal was for directed energy weapons to eventually be the go-to choice for the crews of American warships when facing close-in threats.

The Navy has shared three pictures of the LOCUST system onboard USS George H.W. Bush, seen at the top of this story and below. They were all taken on October 5, 2025, but released today. This coincides with the start of the Navy League’s annual Sea-Air-Space exposition, at which TWZ is in attendance.

The captions to each of the images include the following: “During the live-fire event, [the] LOCUST LWS [laser weapon system] effectively detected, tracked, engaged, and neutralized multiple unmanned aerial vehicles marking a milestone toward fielding operational directed energy capabilities.”

TWZ has reached out to the Navy for more information.

“The successful demonstration of its palletized LOCUST Laser Weapon System (LWS) aboard the USS George H.W. Bush (CVN-77) in October 2025″ was conducted “in collaboration with the U.S. Navy and the U.S. Army Rapid Capabilities and Critical Technologies Office (RCCTO),” according to a press release from AeroVironment.

“During the live-fire event, the Palletized High Energy Laser (P-HEL) system tracked, engaged, and neutralized multiple target drones – marking a major milestone toward fielding operational directed energy capabilities across all domains and platforms,” the release adds. “This achievement validates that the LOCUST LWS is truly platform-agnostic, seamlessly transitioning from fixed-site and land-based mobile platforms, such as the Joint Light Tactical Vehicle (JLTV) and Infantry Squad Vehicle (ISV), to the dynamic and demanding environment of a maneuvering aircraft carrier.”

The central element of LOCUST is a laser directed energy weapon in a turret, which also includes built-in electro-optical and infrared video cameras for target acquisition and tracking. Tertiary sensors, including small-form-factor high-frequency radars and passive radio frequency signal detection systems, can also be used to cue the laser. The JLTV and ISV-based configurations mentioned in AeroVironment’s release both feature small radars.

LOCUST’s power rating is generally understood to be in the 20-kilowatt range at present. When it comes to laser directed energy weapons, this is at the lower end of the power spectrum, fully in line with a system intended to defeat smaller drones. LOCUST has also been demonstrated with a 26-kilowatt power rating, but how much more it could be scaled within the existing form factor is unclear.

As of December 2025, the U.S. Army was known to have taken delivery of palletized LOCUST systems, as well as ones mounted on JLTVs and ISVs. The Army has at least deployed the palletized versions overseas operationally in the past. One of the service’s LOCUST systems was also at the center of a widely criticized and controversial shutdown of airspace around El Paso, Texas, in February of this year, as you can read more about here. The system had been on loan to U.S. Customs and Border Protection (CBP) at the time. Earlier this month, the Pentagon signed an agreement with the Federal Aviation Administration (FAA) regarding the continued use of anti-drone laser systems along the southern border with Mexico.

The U.S. Marine Corps has also moved to acquire JLTV-based LOCUST systems in the past. In addition to appearing to be the first instance of a laser-directed energy weapon going aboard a carrier, last year’s test aboard USS George H.W. Bush also looks to be the first known instance of the Navy even evaluating LOCUST for use on ships or in any other context.

Navy interest in using LOCUST to defend ships, especially very high-value ones like aircraft carriers, is not surprising. For years now, the service has been very active in pursuing shipboard laser and microwave directed energy weapons with a particular eye toward providing additional layers of counter-drone defense.

Experience gained in recent years from operations in and around the Red Sea, as well as against Iran, has only underscored the critical importance of bolstering the ability of U.S. warships to protect themselves against uncrewed aerial threats. The Navy has also been adding counter-drone systems that use physical interceptors as their effectors to a growing number of ships to help address this reality.

In general, lasers like LOCUST offer the promise of functionally unlimited magazine depth, which could be exceptionally valuable in the counter-drone role when faced with large volumes of incoming threats. The dangers that uncrewed aerial systems pose are only set to increase as artificial intelligence and machine learning-driven capabilities, including automated targeting and fully networked swarming, continue to improve while the barrier to entry steadily drops.

Palletized and containerized systems like the P-HEL version of LOCUST can also be employed with more flexibility on a wide variety of ships, as long as sufficient deck space and available power. The test aboard USS George H.W. Bush involved simply lashing the system to the flight deck. This also means the systems can be installed and/or removed more readily depending on mission requirements. The Navy also has a demand for counter-drone capability on land to protect key facilities and assets abroad and at home, where LOCUST would also be relevant.

LOCUST Laser Weapon System

At the same time, especially when it comes to employing lasers on ships, there are also potential pitfalls. As TWZ has previously written:

“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.”

Over the years, the Navy has faced continued and significant hurdles in attempting to field operational laser weapon systems more broadly across its fleets. U.S. military officials have often sought to temper expectations, while also being open about their frustrations with the lack of greater progress, in recent years.

Still, the Navy, in particular, has persisted in its pursuit of these capabilities, given the benefits mentioned earlier. Lasers are set to be a particularly important component of the full arsenal aboard the future Trump class “battleships.”

“My thesis research at [the] Naval Post Graduate School was on directed energy and nuclear weapons,” Adm. Caudle told TWZ and other outlets at a roundtable back 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,” the admiral added, emphasizing that “it has an infinite magazine.”

“What that does for me is it improves my loadout optimization, so that my loadout, my payload volume is optimized for offensive weapons,” Caudle added at the time. Furthermore, “as you increase power, the actual ability to actually engage and keep power on target, and the effectiveness of a laser just goes up.”

Laser directed energy weapons with higher power ratings could potentially defend ships against other threats, including certain types of incoming missiles.

Whether or not the Navy decides to acquire and field LOCUST operationally on its ships, the service’s general demand for more counter-drone capabilities across the board does not look set to decrease any time soon.

April 20 (UPI) — Iran said that it carried out drone strikes on Monday against U.S. military vessels blockading its ports after the U.S. Navy attacked an Iranian-flagged container ship in the Gulf of Oman.

The state-run Tasnim News Agency said the Iranian military “launched drone strikes toward several U.S. military vessels in the area” in retaliation for the boarding and seizure of the Touska on Sunday night while it was en route to Iran from China.

“We caution that the Armed Forces of the Islamic Republic of Iran will soon respond to and retaliate for this act of piracy and armed aggression by the US military,” Khatam al-Anbia Central Headquarters, the Iranian military’s central command, said in a statement

Khatam al-Anbia Central Headquarters said the Iranian Armed Forces had held off from delivering “a decisive response” to “blatant aggression by U.S. terrorist commandos” due to concerns for the safety of family members of the ship’s crew who were on board the Touska.

“Iran’s operational action was delayed in order to protect their lives and security, which were in constant danger,” the statement added.

The U.S. military did not immediately comment on Iran’s claim it conducted drone strikes.

However, U.S. Central Command posted video of the guided-missile destroyer USS Spruance warning the Touska to “vacate your engine room” because it was about to open fire and, some time later, night-vision footage of helicopter-borne U.S. Marines from USS Tripoli conducting an amphibious assault operation to take over the vessel.

CENTCOM said the Spruance intercepted Touska as it was steaming toward the Iranian port of Bandar Abbas, issuing multiple warnings over a six hour period that it was in violation of the U.S. blockade. When it refused to stop, the Spruance fired several rounds from its 5-inch gun hitting the engine room and disabling the vessel.

U.S. Marines from the 31st Marine Expeditionary Unit later boarded the vessel and took control of the vessel, which remains in U.S. custody.

CENTCOM said U.S. forces had ordered 25 commercial vessels to turn back, or return to an Iranian port, in the week since the United States implemented its blockade of Iranian ports on April 13.

However, Sunday was the first time that the U.S. military is known to have opened fire on merchant shipping since the war started Feb. 28.

The escalation came after a rollercoaster weekend that began with Tehran declaring that the Strait of Hormuz was fully open to all commercial shipping for the remainder of the 14-day cease-fire currently in place, which is due to expire on Wednesday.

The move was welcomed by the United States, but the administration of U.S. President Trump made it clear its blockade would remain in place. That prompted Tehran to accuse the United States of violating the cease-fire and by Saturday it declared the strait closed again and at least one tanker was fired on by two Iranian gunboats as it attempted to enter the sea lane.

The developments have cast doubt over peace talks, which are due to resume in Islamabad, Pakistan, later Monday or first thing Tuesday.

Trump said in a post on his Truth Social platform that U.S. negotiators would arrive in the Pakistani capital on Monday night, with the White House later confirming that Vice President JD Vance would again head up the U.S. delegation, picking up from where he left off from in an initial round of talks on April 11 that failed to produce a breakthrough.

Tehran said Monday it had not yet decided whether it would attend.

“As of now, while I am speaking to you, we do not have a plan for the next round of negotiations, and no decision has been taken in this regard,” Foreign Ministry spokesperson Esmaeil Baqaei said at a press conference in Tehran.

Referencing the ongoing U.S. blockade and seizure of the container ship, Baqaei accused the United States of actions that “are in no way indicative of seriousness in pursuing a diplomatic process.”

However, the comments do not mean Iran will not show in Islamabad.

The Iranian side only confirmed participation in the first round of negotiations at the last minute.

Global oil prices, which fell sharply on Friday after Iran said the Hormuz Strait was open, rose again over the weekend but were holding steady in late morning trade in London where Brent crude for June delivery contract was changing hands at $95.24 a barrel and West Texas Intermediate for May delivery was changing hands at $88.89 a barrel.

A day into the U.S.-imposed military blockade of the Strait of Hormuz, several ships have apparently transited the narrow waterway, including at least two that reportedly had previously stopped at Iranian ports. However, U.S. Central Command (CENTCOM) is pushing back against claims that vessels ran the blockade. As we noted yesterday, CENTCOM said the maritime exclusion operation would be “enforced impartially against vessels of all nations entering or departing Iranian ports and coastal areas, including all Iranian ports on the Arabian Gulf and Gulf of Oman.”

Meanwhile, there are indications that the U.S. and Iran may continue seeking a diplomatic offramp to the crisis, which began Feb. 28 when America and Israel began bombarding the Islamic Republic. We will discuss that in greater detail later in this story.

Christianna, a Liberia-flagged cargo ship, “exited the Persian Gulf through the strait on Monday night, after leaving the Iranian port city of Bandar Imam Khomeini,” The New York Times reported, citing the global trade intelligence firm Kpler. It said the ship was not carrying any cargo.

In addition, Elpis, a methanol carrier, “traversed the strait roughly around the time that the U.S. blockade began, according to ship-tracking data,” the newspaper added, “Kpler said that the vessel had been at the Iranian port of Bushehr. The United States had placed sanctions on the ship last year under an earlier name, Chamtang, over its connections to the Iranian oil trade.”
