In a direct confrontation with Russia, European NATO states would likely be even more vulnerable than Ukraine to swarms of Russia’s new jet-powered strike weapons, Fabian Hoffmann of the Norwegian Institute for Defence Studies (NIDS) argued in a 20 October op-ed for the Center for European Policy Analysis (CEPA). He calls them low-cost cruise missiles. Just three days earlier, Romania met what it believes were two of them over the Black Sea.

Romanian F-16 fighter jets shot down two jet-powered Geran-family drones over Romania’s territorial waters on 17 October, the Defense Ministry said. Interim Defense Minister Radu Miruță said they flew at about 450 km/h and were likely Geran-4s, the first of that type Romania had downed.

Faster drones for a faster war

Russia began using the Geran-4 in May in response to effective Ukrainian interceptor drones, Ukraine’s military intelligence (HUR) said, adding that it reaches up to 500 km/h. By June, those interceptors were downing about half of slower Shahed-type drones, defense adviser Serhii Beskrestnov estimated.

Hoffmann traces the shift to the Geran-3, a model Ukraine recovered intact in 2025. In his account, a Chinese JT80 turbojet roughly doubled its speed, from 185 to 350 km/h. However, he puts newer models, including the Geran-4, at 600 km/h or more, above HUR’s figure for that model.

By his estimate, each costs $150,000–$250,000, against about $50,000 for a long-range drone. Still, from Russia’s perspective, he wrote, that buys a significantly higher chance of getting through.

Engines are the bottleneck

Hoffmann argues defenses must match the threat’s speed, for example with jet-powered interceptor drones. Ukraine already fields some. On 4 October, President Zelenskyy said its Bars interceptors had shown the highest percentage among Ukrainian interceptors, about 30% of targets, according to Militarnyi. One unit destroyed five aerial targets with five Bars interceptors, Defense Minister Yevhenii Khmara later told journalists. He also called aviation one of the most effective tools against jet drones.

Hoffmann’s concern is scale. Jet engines are in short supply, he wrote, because too few European and US suppliers can meet demand. Ukraine’s Defense Industry Council flagged a shortage of such engines for its drones in April. In his view, gun systems and higher-end missile defenses are too scarce or too costly to fill the gap.

The U.S. Army wants to infuse new autonomous capabilities into its current and future fleets of amphibious landing ships and other watercraft. The service is also aiming to acquire up to 100 new purpose-built uncrewed surface vessels (USV). The maritime assets the service has now, often referred to as ‘the Army’s Navy,’ are obscure and generally underappreciated. However, the small force offers an important additional set of naval logistics capabilities, especially for any future fight in the Pacific, which could be further bolstered with optionally-crewed or entirely uncrewed platforms.

Army Maj. Gen. Frederick Crist, head of 8th Theater Sustainment Command (TSC), issued plans for future autonomous watercraft capabilities during a talk last week during a talk at the Association of the U.S. Army’s (AUSA) main annual symposium. 8th TSC, which has its main headquarters at Fort Shafter in Hawaii, is one of the top formations tasked with managing U.S. military logistics across the Pacific.

“In order to be able to increase theater distribution, we have the two composite watercraft companies, at end state there, west of the IDL [International Date Line],” Crist explained, referring to the Army’s future planned maritime force posture in the Pacific. “We continue partnering with industry to be able to move into autonomous watercraft systems to be able to conduct other means of maritime distribution.”

To take a step back quickly, as part of its broader regional role, 8th TSC also has forward-deployed elements in Japan. This includes the 5th Transportation Company, which is currently organized as what the Army calls a composite watercraft company. As of 2024, the unit had a pair of General Frank S. Besson class Logistics Support Vessels (LSV), as well as 10 smaller Landing Craft Utility (LCU) type vessels and four small tugs, according to the Government Accountability Office (GAO).

The Army has eight LSVs, in total, and these are by far its largest and most capable ships. The two youngest LSVs, which were acquired in the mid-2000s, also form a distinct subclass, and their design is optimized for long-distance open-ocean operations, as you can read more about here. It’s not immediately clear which LSVs are currently assigned to the 5th Transportation Company. The unit is also set to receive new Maneuver Support Vessel (Light) landing craft.

Until very recently, the 10th Support Group (Regional), headquartered in Okinawa, was more directly responsible for overseeing forward-deployed Army logistics units in Japan. Earlier this month, the Army performed a so-called ‘reflagging’ of that formation, a largely administrative process that transformed it into the 45th Sustainment Brigade.

As part of the reflagging of the 10th Support Group into the 45th Sustainment Brigade, the Army has also been pushing ahead with plans for “the standup of a second composite watercraft company in Yokohama North Dock,” in the port city of the same name on the Japanese home island of Honshu, Maj. Gen. Crist explained last week. “That end state will have two composite water[craft] companies west of the IDL [International Date Line] under the command and control of the 45th Sustainment Brigade.”

When it comes to the watercraft assigned to these units, “we’re also moving into the autonomous lane,” Crist added. “Just in August, USARPAC [U.S. Army Pacific] had an opportunity to conduct an experiment by retrofitting an existing commercial vessel, the HOS Resolute [sic; HOS Resolution], with a kit to provide autonomous navigation.”

Maritime autonomy firm Sea Machines was able to integrate its SM300 software package on the HOS Resolution in just nine days for this demonstration. The ship is a 257-foot-long offshore support vessel more typically used to support oil and gas rigs. However, it features a stern ramp and four jack-up legs that also make it well suited to loading and unloading cargo at remote beaches.

For years now, the U.S. Marine Corps has also been experimenting with the HOS Resolution and other similar ships more generally. That service has been using the vessels to help refine its new expeditionary and distributed concepts of operations, which are themselves heavily centered on future conflict scenarios in the Pacific. The Marines have brought those capabilities to Army demonstration exercises in the past, as well.

The Army sees the August experiment as a potential stepping stone to integrating increasing degrees into its existing watercraft fleets.

“You could increase the fleet of autonomous vessels by tapping into the existing manned fleet,” Maj. Gen. Crist said. “Put on retrofitting kits to be able to conduct navigation, and then eventually propulsion and engine room activities, and eventually get to a fully autonomous system.”

Even just adding in autonomous navigation capabilities could help reduce the workload for the human crews on Army vessels and provide added margins of safety. Blending autonomy with “propulsion and engine room activities” could improve reliability and reduce maintenance demands. Being able to operate those ships in a fully uncrewed mode, if desired, would open up additional operational possibilities, including just for repositioning ships across the broad expanses of the Pacific.

Reduced manning requirements could be especially attractive for the Army’s ‘Navy,’ which is already a very small part of the service’s overall force structure. Last week, Maj. Gen. Crist also talked about further leveraging traditional crewed vessels owned and/or operated by contractors.

“It’s going to be a broad portfolio of systems of systems,” he said of the overall watercraft vision for the Pacific. “Army watercraft with Army Mariners will be, of course, one aspect of it. We also look for the opportunity to be able to leverage USTRANSCOM’s (U.S. Transportation Command) contracting capability to leverage operational support vessels that are commercially owned and commercially operated. We’re considering ways of being able to have commercial vessels that become manned by Army mariners.”

It is also interesting to note here how extremely similar this all sounds to the modifications the U.S. Navy made to the Spearhead class Expeditionary Fast Transport USNS Apalachicola ahead of its commissioning in 2023. However, despite tens of millions of dollars spent and successful demonstration of autonomous capabilities, the Navy curiously decided to put the Apalachicola into service without any plan to make use of these features operationally. There does not appear to have been any effort to integrate these capabilities more broadly within the Spearhead class since then, either.

Last year, the Navy struck the four oldest Spearhead class ships from its rolls entirely and has put several others on reduced operating status, ostensibly as a cost-saving measure. The service is still acquiring new Expeditionary Fast Transports, including members of the Expeditionary Medical Ship subclass that feature expanded medical facilities. The Spearhead class was born out of a program specifically to meet Army and Marine Corps requirements, and the ships are regularly used to support those services in the Pacific and elsewhere globally.

The Army also wants to expand its fleets of purpose-built uncrewed surface vessels (USV) for use in the Pacific, as well as elsewhere globally. Just earlier this year, Army Maj. Gen. Gavin Gardner, who preceded Maj. Gen. Crist as head of the 8th Theater Sustainment Command, said he wanted to rapidly acquire as many as 100 drone boats. His vision included larger USVs capable of carrying eight to 10 standardized shipping containers.

“I could see those operating in the U.S. PACOM area of responsibility,” Gardner told reporters at a roundtable in June, according to Military Times. “I think that gives you a ton of operations, inventory in motion, easy to respond. And then because they’re autonomous, and we can work with our partner nations forward, you have those berthed up everywhere from Korea to Japan, the Philippines, Australia, Singapore, Thailand, etc.”

“Clearly, [the autonomous vessels] would be forward in the theater, kind of moving supplies, because we have a constant demand for Army watercraft time now, to deliver equipment and supplies forward in the theater,” Gardner added at that time.

One of the inherent benefits of the Army watercraft fleets, and its LSVs in particular, is their ability to help alleviate the need for the U.S. Navy to meet more localized littoral logistics needs, if they are even available to help in the first place. Navy amphibious and military sealift ships would already be heavily strained by high demand during any major conflict in the Pacific or elsewhere globally. This could easily be further exacerbated by threats to those supply lines. All of this has already been underscored this year by pressure on maritime logistics chains in the context of the war with Iran. The Army’s ‘Navy’ also offers valuable additional capabilities and capacity in non-combat contingencies, such as responding to natural disasters.

More generally, the Army has been working to expand its use of smaller USVs, including speedboat-like designs, in various roles. The service has clearly been paying close attention to Ukraine’s very successful use of drone boats in one-way kamikaze attacks, as well as ones armed with guns and rockets and examples configured as launch platforms for surface-to-air missiles and weaponized uncrewed aerial systems (UAS).

The 7th Infantry Division, one of the Army’s main maneuver combat formations in the Pacific, just recently experimented with a Ukrainian-developed Magura-series USV during an exercise in Michigan. That particular USV was configured to launch a quadcopter-type drone. Another member of the Magura family was observed being used in a one-way-attack configuration by U.S. Army Green Berets from the 1st Special Forces Group during the annual Balikatan exercise in the Philippines earlier this year.

The Army has also been experimenting with American-designed USVs. The aforementioned recent exercise in Michigan also featured a Saronic Corsair, the same type of USV that the Navy used to rescue the crew of an Army AH-64 Apache attack helicopter that went down in the Gulf of Oman in June. Explosive-laden Corsairs were also used to carry out the first known U.S. kamikaze USV attack, which was launched against a coastal target in Iran in July.

During another separate exercise in the Philippines this year, Salaknib 2026, Army forces used unarmed Rampage USVs from U.S. firm Havoc, as seen below. As part of that exercise, the USVs escorted a crewed General Frank S. Besson class LSV to its destination, heading out in front to help spot potential hazards.

“There’s all the work that the Department’s already doing with autonomy and autonomous systems that we look to take advantage of in the [Pacific] theater, as well,” Maj. Gen. Crist said at AUSA.

The Navy and the Marine Corps have both been working to grow their operational fleets of smaller USVs, as well as larger ones, in recent years. At the same time, the Navy has suffered years of setbacks and shakeups in its efforts to operationalize bigger and more capable designs. The service awarded contracts for a total of 30 new medium-sized USVs last month in its latest attempt to reverse that trend.

In September, Secretary Pete Hegseth also announced several new initiatives aimed at further expanding use of uncrewed platforms and advanced autonomous capabilities across the U.S. military and all domains. The Pentagon is presently laying the groundwork for the establishment of an all-new top-level Autonomous Warfare Command (AUTOWARCOM), which it hopes to see come to fruition next year.

What is clear now is that the Army’s vision for future watercraft operations, especially in the Pacific, is increasingly autonomous.
