From Bandar Abbas to Brownsville: America Is Building the Shipyard for Autonomous War

Three unmanned boats entered Iran’s Bandar Abbas naval harbour on 12 July 2026 and struck a submarine and the infrastructure used to maintain Iran’s undersea fleet.

The vessels were not improvised Ukrainian sea drones or remotely controlled speedboats assembled for a single operation. They were Corsair autonomous surface vessels manufactured by Saronic Technologies, an American defence company established only a few years earlier.

The operation marked the first acknowledged combat employment of unmanned surface vessels by US forces. Footage released by US Central Command showed the vessels approaching the naval installation before detonating against their targets. The operation was intended to degrade Iran’s ability to threaten military and commercial movement around the Strait of Hormuz.

Four days later, Saronic announced Port Alpha, a proposed $3.2 billion shipyard at the Port of Brownsville in Texas. The facility is intended to manufacture medium- and large-class autonomous and autonomy-capable vessels.

Viewed separately, the two events belong to familiar categories. Bandar Abbas was a military operation. Brownsville was an industrial investment promising a new shipyard, advanced manufacturing and thousands of jobs.

Viewed together, they reveal something more consequential.

The United States has moved from experimenting with autonomous maritime systems in Middle Eastern waters to employing them against a strategically important naval target. It is now attempting to construct the industrial capacity required to manufacture such vessels at scale.

The connection between Bandar Abbas and Brownsville is therefore not incidental. The attack demonstrated the operational effect. Port Alpha represents the attempt to industrialise it.

The target was a naval system, not merely a submarine

The importance of the Bandar Abbas operation lies partly in what the Corsairs targeted.

Iran’s submarine force was already under severe pressure. Its ageing Russian-built Kilo-class submarines had limited availability, while its smaller Ghadir-class boats depended upon specialised shore infrastructure for lifting, inspection, repair and maintenance.

The Ghadirs are approximately 125-tonne midget submarines designed for shallow coastal waters. Their limited endurance prevents them from functioning as conventional blue-water submarines, but they can carry torpedoes, lay mines and potentially launch short-range anti-ship weapons.

In the confined geography around the Strait of Hormuz, those limitations do not make them irrelevant. A small submarine resting on the seabed or waiting near a shipping lane could still threaten tankers, naval escorts or vessels attempting to transit a contested strait.

The US operation did not need to locate and destroy every surviving Iranian submarine. Instead, the Corsairs reportedly struck the infrastructure required to sustain the fleet.

An analysis in The Maritime Executive concluded that the attack destroyed the lifting mechanism used to remove Ghadir submarines from the water, damaged the associated maintenance facility and destroyed one submarine positioned on the hoist.

Even if another Ghadir survived elsewhere, Iran appears to have lost an important part of the infrastructure needed to maintain and regenerate the force without substantial reconstruction or foreign assistance.

The assessment that Iran’s submarine force has been “consigned to history” is more categorical than any formal Pentagon declaration. Nevertheless, the underlying operational logic is persuasive.

Naval power depends upon more than the vessels visible at sea. It requires dry docks, lifting systems, maintenance halls, replacement components, trained technicians, secure berths and the ability to return damaged platforms to service.

Destroying those supporting systems can produce effects far beyond the physical loss of a single hull.

The Corsairs therefore attacked the submarine force as an industrial and logistical system.

This is one of the central lessons of the operation. Autonomous weapons do not necessarily need to destroy the most expensive or heavily protected platform directly. They can instead attack the infrastructure that allows that platform to remain operational.

The Middle East became America’s autonomous maritime laboratory

The Bandar Abbas attack did not emerge from a sudden American decision to imitate Ukrainian tactics.

Its institutional foundations had been built over several years through US Naval Forces Central Command, the Fifth Fleet and, most importantly, Task Force 59.

Established in Bahrain in September 2021, Task Force 59 became the US Navy’s first formation dedicated specifically to integrating unmanned systems and artificial intelligence into maritime operations.

Its location was strategically important.

The Fifth Fleet’s operating area covers approximately 2.5 million square miles, extending across the Arabian Gulf, Gulf of Oman, Red Sea, Gulf of Aden, Arabian Sea and parts of the Indian Ocean. It includes the Strait of Hormuz, Bab al-Mandab and the approaches to the Suez Canal.

The region offered the Navy an environment where dense commercial shipping, surveillance requirements, political tension, electronic interference and the possibility of hostile action existed simultaneously.

Task Force 59 initially concentrated heavily on maritime-domain awareness. Saildrone Explorers, MANTAS vessels and other unmanned platforms were used to observe shipping activity, transmit imagery and extend the area that could be monitored without requiring a crewed warship to remain permanently on station.

The concept was often described as placing more eyes on the water. Unmanned vessels could patrol routes, identify unusual activity and transmit information to operations centres in Bahrain and elsewhere. Artificial intelligence could then help human operators interpret the growing volume of sensor data.

By March 2024, then-CENTCOM commander General Michael Kurilla told the US Senate that Task Force 59 had dozens of unmanned surface vessels operating at sea and providing indications and warnings to maritime operations centres in real time.

The programme was no longer restricted to occasional technology demonstrations. Its platforms were contributing to the regional maritime picture during normal operations.

The Middle East had become a place where autonomy could be tested under real operating conditions rather than solely at controlled ranges off the American coast.

From experimentation to deployment

A significant institutional change occurred in January 2024 when Task Force 59 created Unmanned Task Group 59.1, known as “The Pioneers”.

The distinction was important.

Task Force 59 had already evaluated more than 20 unmanned systems. Task Group 59.1 was created to move suitable technologies beyond experimentation and into operational deployment alongside human operators.

The new formation was intended to connect commercial technology developers with the sailors using their systems in theatre. Its role was to accelerate the process through which a product could be tested, modified, integrated and placed into operational service.

By the time Task Group 59.1 was established, its personnel had accumulated more than 60,000 hours of unmanned operations across dozens of exercises and missions. Those figures demonstrated how far the programme had progressed from isolated trials.

The Navy had also started exploring explicitly kinetic applications.

In the months preceding the unit’s establishment, Task Force 59 conducted exercises in which live munitions were launched from a T-38 Devil Ray unmanned surface vessel against training targets. The weapons reportedly hit their targets during each attempt.

The significance was clear. The programme was no longer limited to cameras, sensors and passive surveillance.

The Navy was examining how unmanned surface vessels could contribute to a hybrid fleet in which crewed ships operated alongside autonomous and remotely controlled systems conducting reconnaissance, logistics, electronic warfare, targeting and attack missions.

The evolution continued during Digital Talon 3.0 in November 2024.

The exercise involved unmanned aerial and surface platforms operating together, including the launch of an aerial drone from an unmanned surface vessel. Earlier Digital Talon exercises had already examined kinetic applications and the use of live weapons. The third iteration concentrated on more advanced tactics and the integration of multiple unmanned capabilities.

By then, Task Force 59 had tested, upgraded or operated more than 23 different unmanned systems in the region.

This progression helps place the Bandar Abbas attack in context.

The individual platform was different. The payload and target were different. But the underlying operating concept had been developed through years of experimentation: unmanned vessels working across different domains, communicating with operations centres and crewed platforms, navigating difficult waters and gradually assuming more complex missions.

The less visible challenge: operating without reliable GPS

The next phase of the programme addressed a problem that receives less attention than weapons, speed or vessel design but is essential to autonomous warfare: navigation in a disrupted electromagnetic environment.

The Strait of Hormuz and surrounding waters have repeatedly experienced GPS interference, spoofing and jamming. Commercial ships have reported false positions, disappearing signals and navigation systems incorrectly placing them on land or at distant airports.

An autonomous vessel that depends completely on satellite navigation can become ineffective if its signal is denied or manipulated. It may drift, follow an incorrect route, abandon the mission or become vulnerable to interception.

CENTCOM’s 2025 posture statement described Task Force 59 testing technologies intended to improve the resilience of maritime inertial-navigation systems when jamming and spoofing prevented access to GPS.

The command connected these trials to a broader objective: testing emerging technologies in theatre, reducing the operational uncertainty surrounding them and transferring successful systems into larger acquisition programmes.

This part of the programme moves the story beyond the visible spectacle of a fast unmanned boat.

For a Corsair or similar platform to travel hundreds of nautical miles, enter hostile waters and approach a defended naval target, it must do more than move quickly. It must navigate through interference, communicate securely, confirm its route and continue functioning when parts of the wider network are disrupted.

The Middle East allowed the United States to test those requirements in an environment where electronic warfare was not hypothetical.

By 2025, CENTCOM was also openly identifying scale as the next challenge. Its innovation formations could test and deploy systems at the tactical edge, but the military services and acquisition establishment would need to transform successful technologies into programmes capable of producing meaningful numbers.

That is the institutional bridge connecting Task Force 59 to Brownsville.

Aerial attack drones foreshadowed the transition

Another indication appeared in December 2025.

Task Force 59 launched a Low-cost Unmanned Combat Attack System from the littoral combat ship USS Santa Barbara in the Arabian Gulf. It was the first time the US Navy had launched a one-way attack aerial drone from a vessel at sea.

Known as LUCAS, the system belonged to Task Force Scorpion Strike, which CENTCOM described as the US military’s first one-way attack drone squadron deployed to the Middle East.

LUCAS was an aerial rather than maritime attack system, but its employment demonstrated the direction of travel.

Task Force 59 was becoming more than a maritime-surveillance organisation. It was developing into an operational mechanism for deploying affordable, expendable and long-range attack systems from existing naval platforms.

The conceptual boundary between reconnaissance drone, autonomous boat, missile carrier and one-way attack weapon was becoming less rigid.

A single unmanned platform might conduct surveillance during one mission, carry supplies during another, support rescue operations during a third and deliver an explosive payload during a fourth.

That versatility would soon be demonstrated by Saronic’s Corsair.

Corsair crossed the boundary into combat

Saronic designed the 24-foot Corsair to carry approximately 1,000 pounds of payload and travel more than 1,000 nautical miles, depending upon its configuration and operating conditions.

Those characteristics explain part of its military appeal.

Corsair is large enough to carry useful sensors, supplies, communications equipment or explosives, but small enough to be manufactured and deployed in much greater numbers than conventional naval vessels.

Before the Bandar Abbas attack, a Corsair reportedly assisted in rescuing two US Army Apache helicopter crew members near the Strait of Hormuz. The episode demonstrated the advantage of sending an unmanned boat into an area where exposing another crew could create additional risk.

The same basic vessel type was subsequently used as a one-way attack weapon.

This transition from rescue platform to strike system illustrates why unmanned surface vessels cannot be understood solely as substitutes for conventional ships. Their value lies partly in their adaptability.

A crewed patrol boat is designed around the requirement to protect its occupants. It needs accommodation, controls, life-support provisions, evacuation procedures and structural features intended to preserve human life.

An unmanned boat does not face the same constraints. Its payload and software can be modified for a specific operation. It can be sent into mined waters, exposed to coastal missiles or deliberately sacrificed against a high-value target.

At Bandar Abbas, three Corsairs reportedly approached the submarine facility before detonating against the target area.

Even without public access to every detail of the command-and-control system, the operation demonstrated the central proposition behind one-way unmanned attack vessels: they can impose strategic costs without requiring American personnel to enter the final engagement zone.

It was a direct expression of the operational concept Task Force 59 had spent years developing.

From Ukrainian improvisation to American industrialisation

The influence of Ukraine’s Black Sea campaign is difficult to ignore.

Ukrainian forces used explosive unmanned boats to attack Russian naval vessels, ports, surveillance assets and supporting infrastructure. Those operations helped constrain the Russian Black Sea Fleet and forced some vessels away from Sevastopol.

The resemblance to Bandar Abbas is evident. Comparatively inexpensive unmanned boats penetrated or bypassed harbour defences and attacked conventional naval assets within their own supporting infrastructure.

But the emerging American model differs in one important respect.

Ukraine’s sea-drone programme developed under the pressure of national survival. It relied heavily upon rapid adaptation, distributed production and continuous battlefield modification. Designs changed as Russian countermeasures evolved.

Saronic is attempting to place the same underlying logic within a larger and more permanent industrial system.

The company has produced hundreds of Corsairs and is developing larger vessels, including Mirage and the 150-foot Marauder. These platforms are not all intended to become expendable weapons.

They form part of a broader vision in which autonomous vessels conduct surveillance, logistics, patrol, electronic warfare and combat missions at different ranges and levels of endurance.

Port Alpha is the physical expression of that ambition.

Why Brownsville matters

Saronic selected the Port of Brownsville for a facility intended to manufacture medium- and large-class autonomous and autonomy-capable vessels rather than only small drone boats.

The initial development is expected to cover approximately 835 acres, with access to a substantially larger expansion area. The project could eventually employ as many as 10,000 people if the company reaches its long-term production targets.

The State of Texas supported the project as part of a wider attempt to attract advanced defence manufacturing and new maritime industry.

Brownsville offers several advantages.

The port has direct access to the Gulf of Mexico, extensive undeveloped land, an established maritime-industrial workforce and experience supporting offshore energy, heavy fabrication and ship recycling.

It is also located near one of the most unusual concentrations of emerging strategic infrastructure in the United States.

SpaceX’s Starbase operations at Boca Chica have already turned the area into a centre for rocket construction and launch activity. Saronic would add autonomous naval manufacturing. The wider region connects energy infrastructure, Gulf shipping routes, advanced technology and the US–Mexico border.

Brownsville is therefore becoming more than a port competing for cargo and industrial tenants. It is emerging as a strategic production corridor.

The symbolism is difficult to miss.

Autonomous systems tested in the Arabian Gulf and used against Iran would be manufactured beside the American Gulf Coast.

One Gulf provided the operational laboratory. The other is being positioned as the industrial base.

A different response to America’s shipbuilding crisis

The Port Alpha announcement also intersects with the wider crisis confronting American shipbuilding.

The United States has struggled to deliver submarines and surface combatants on schedule. Existing shipyards face workforce shortages, ageing infrastructure, complex supplier networks and rising costs. China, meanwhile, possesses far greater commercial shipbuilding capacity.

Saronic is not offering a complete answer to those structural problems. Autonomous vessels cannot replace aircraft carriers, nuclear submarines, destroyers or amphibious ships across every mission.

Port Alpha nevertheless represents an attempt to redefine part of the problem.

Instead of rebuilding American maritime power solely by expanding traditional naval yards, Saronic proposes manufacturing a new category of vessel using modular designs, software-defined capabilities and production methods influenced by advanced technology manufacturing.

The objective is not merely to build individual ships more efficiently. It is to alter the composition of the fleet.

A future US naval force could combine relatively small numbers of highly capable crewed warships with much larger numbers of unmanned systems. Some would act as distributed sensors. Others would carry missiles, supplies, electronic-warfare equipment or mine-countermeasure payloads. Some could remain at sea for extended periods, while others would be designed to be expendable.

In that model, naval mass would not come exclusively from producing more destroyers.

It would also come from deploying hundreds or thousands of autonomous vessels around them.

The Bandar Abbas operation offered a narrow but powerful demonstration of that concept.

Three unmanned vessels did not replace the US Navy. They extended its reach and attacked a target that might otherwise have required a different combination of aircraft, missiles, special forces or crewed vessels.

The unanswered questions

The apparent success of the operation should not obscure the difficult questions surrounding autonomous warfare.

It remains unclear how independently the Corsairs operated during the final approach, what level of human supervision was retained and who authorised the terminal attack.

“Autonomous” can describe a wide spectrum, ranging from automated navigation along a predetermined route to systems capable of identifying and engaging targets with limited human input.

Those distinctions carry legal, ethical and operational consequences.

The vulnerability of the command network is another concern. Autonomous vessels must continue functioning amid jamming, spoofing, cyberattack and physical damage. A system designed to reach an enemy harbour must also be protected against diversion, capture or manipulation.

Cost will matter as well.

Attritable vessels change the economics of warfare only when they are sufficiently inexpensive to lose and sufficiently easy to replace. A sophisticated autonomous vessel that becomes progressively more expensive through additional sensors, communications equipment and payloads could reproduce the same procurement problems it was intended to avoid.

Adversaries will also adapt.

Harbour barriers, nets, rapid-firing weapons, helicopters, electronic warfare and interceptor boats can all complicate unmanned attacks. The success of three Corsairs at Bandar Abbas does not guarantee that the same tactic will repeatedly succeed against prepared defences.

Warfare, however, does not require a technology to be invulnerable. It requires the system to create effects disproportionate to its cost and the risk imposed upon its operator.

At Bandar Abbas, the Corsairs appear to have done precisely that.

The shipyard is part of the weapon

The most important conclusion is that Port Alpha should not be viewed merely as the location where Saronic will manufacture vessels.

Industrial capacity is part of the military system.

A country can possess an effective autonomous weapon but still lack the ability to replace it quickly, improve it after combat or deploy it in numbers sufficient to overwhelm an opponent’s defences.

The production line, software architecture, supplier network and workforce determine whether a tactical innovation remains a novelty or becomes a durable source of military power.

Task Force 59 gave the United States a place to test unmanned systems under operational conditions. Task Group 59.1 moved selected technologies closer to routine deployment. Digital Talon explored kinetic applications and integration across multiple domains. The 2025 programme addressed navigation resilience, scaling and the introduction of one-way attack systems.

The 2026 operation at Bandar Abbas brought those strands together.

Port Alpha is intended to take the next step.

The United States did not simply use three unmanned boats against Iran. It demonstrated a form of naval warfare that Saronic now intends to manufacture at industrial scale.

That is the real connection between Bandar Abbas and Brownsville.

The target in Iran was the infrastructure sustaining an older naval force.

The investment in Texas is infrastructure for building the next one.
