The ‘Foreign’ Vehicle That Beat Every American Competitor and Replaced the US Marine Corps AAV D

2009, a private testing facility in the foothills outside Bolzano, northern Italy. A machine rolls off a concrete ramp and into open water. It weighs more than 30 tons. It rides on eight wheels. Its hull is shaped like the belly of a warship. A deep V of hardened steel designed not for speed, but for survival.

Water rises past the wheel arches, past the lower hull plates, and then something happens that should not happen to a vehicle this heavy. It floats. It moves. Twin propellers churn the surface behind it. And it pushes forward through the water under its own power. Steady, stable, and fully controlled. It looks absurd.

An armored box the size of a city bus swimming. Engineers from Iveco Defence Vehicles stand on the shore taking measurements. No military has ordered this machine. No contract exists. No requirement document demanded it. This is a private venture, funded entirely by the company, built on a bet that someone, somewhere, would eventually need an armored vehicle that could drive out of the ocean and then keep up with a main battle tank on the highway. They were right.

Within a decade, this machine would enter the most competitive military vehicle trial in modern American history. It would face off against entries from five of the largest defense contractors on Earth, including multiple American designs backed by billions of dollars in corporate investment. It would be dismissed as foreign, mocked as European, and questioned by members of the United States Congress who could not understand why the most powerful military on the planet needed to buy Italian. It would beat every single one of them. It would win a contract worth more than 1.2 billion dollars, enter full-rate production, and become the vehicle that replaced the longest-serving amphibious platform in United States Marine Corps history. Over 600 would be ordered across four variants. It would be deployed to the Pacific, to the Philippines, to Okinawa, and to the Korean Peninsula. Its name was the Super AV. The United States Marine Corps would call it the Amphibious Combat Vehicle. And it was the machine that proved the future of American amphibious warfare would be built on Italian engineering. To

understand why the most powerful marine fighting force on the planet went shopping in Italy, you need to understand the crisis the United States Marine Corps faced in the early 2000s. For decades, the Marines had relied on a single platform for ship-to-shore movement, the Assault Amphibious Vehicle.

Originally designated the LVTP-7, it entered service in 1972. Its basic design dated to the late 1960s. By the time American forces invaded Iraq in 2003, the vehicle was already over 30 years old. Its aluminum hull was thin. Its bottom was flat, offering almost no protection against mines or improvised explosive devices.

Its water speed was painfully slow. Its automotive components were aging out of production, and spare parts were becoming harder to find every year. In the streets of Nasiriyah in March 2003, eight Assault Amphibious Vehicles were damaged or destroyed during a single engagement. The vehicle that was supposed to deliver Marines from the sea to the fight was struggling to survive the fight itself.

The Marines knew they needed a replacement, and they had one in development. It was called the Expeditionary Fighting Vehicle. Originally designated the Advanced Amphibious Assault Vehicle, it was the most ambitious armored vehicle program in American history. Built by General Dynamics, the Expeditionary Fighting Vehicle was designed to do something no vehicle had ever done.

It would skim across the surface of the open ocean at 29 mph on water jets, launched from ships more than 25 mi offshore, and then transition to land combat at 45 mph. It was supposed to be the future. It weighed 80,000 lb. It carried 18 Marines and a crew of three, and it consumed more than 3 billion dollars in development funding before a single production vehicle was delivered.

The problem was simple. It did not work, not reliably. The vehicle’s planing hull, designed to rise out of the water at speed like a powerboat, required enormous engine power and generated enormous mechanical stress. Its retractable tracks and transforming bow flaps added layers of complexity that broke constantly under saltwater exposure.

Seals failed, hydraulics leaked, electronics corroded. A 2006 operational assessment exposed catastrophic reliability failures. The vehicle was spending more time in maintenance bays than in the water. In 2007, the program breached its cost ceiling so badly, it triggered an automatic congressional review under the Nunn-McCurdy Act.

The projected cost to complete procurement of 573 vehicles climbed past 11 billion dollars, with each vehicle expected to cost approximately 24 million, more than a main battle tank. Marine Corps Commandant General James Amos would later say that despite the best efforts of all involved, the program had become too onerous.

On January 6th, 2011, Secretary of Defense Robert Gates recommended its cancellation. He described an 80,000-lb armored vehicle that skims the surface of the ocean at high speeds as a concept that had already consumed more than 3 billion dollars to develop, with another 12 billion needed to build a fleet. The Marine’s number one ground acquisition priority was dead.

3 billion dollars spent, zero vehicles fielded. The Marines were back to the aging Assault Amphibious Vehicle with no replacement in sight. What followed was a scramble. The Marine Corps launched a new program, initially called the Marine Personnel Carrier, designed to be the opposite of the Expeditionary Fighting Vehicle in every way.

No exotic technology, no skimming across the ocean at high speed, no transforming hull. Instead, the Marines wanted a proven existing vehicle that could swim from ship to shore, survive mine blasts and ambushes on land, carry a full squad of Marines, and be affordable enough to actually buy in real numbers.

The requirement was restructured in 2014 as the Amphibious Combat Vehicle Program. Five companies entered the competition. BAE Systems teamed with Iveco Defence Vehicles of Italy, offering the SuperAV, an 8×8 wheeled amphibious vehicle already proven in Italian testing. SAIC partnered with ST Kinetics of Singapore offering the Terrex 2.

Lockheed Martin entered a design derived from the Finnish Patria AMV. General Dynamics Land Systems submitted a vehicle based on the Canadian LAV platform. A small Michigan firm called Advanced Defense Vehicle Systems also competed. Every major entry had foreign DNA.

There was no purely American 8×8 amphibious design available. The question was never whether the winner would have foreign origins. The question was which foreign platform could best serve American Marines. On November 24th, 2015, the Marine Corps down selected to two finalists, BAE Systems and SAIC. Each received contracts to build 16 prototypes. $103.

8 million for BAE and $121.5 million for SAIC. General Dynamics protested the decision arguing the Marines had evaluated bids by different standards than originally advertised. The Government Accountability Office denied the protest in March 2016 finding the evaluation was reasonable and consistent.

What followed was 18 months of brutal competitive testing. Prototypes from both finalists were driven through deserts at temperatures exceeding 120° F, frozen in Arctic conditions at Fort Greely in Alaska where vision blocks and weapon station optics iced over and fogged, launched from the well decks of amphibious ships in open ocean swells, submerged in surf zones off the California coast, and subjected to live fire against 14.

5 mm armor-piercing rounds and rocket-propelled grenades. The testing covered Camp Pendleton in California, Yuma Proving Ground in Arizona, Aberdeen Test Center in Maryland, and cold weather facilities in Alaska and New Jersey. Both vehicles had to demonstrate ship-to-shore swimming, beach landings, highway speed, blast survivability, and the ability to carry a full squad of Marines with two days of supplies.

Evaluators tracked every breakdown, every maintenance hour, every failed component. They measured how quickly Marines could exit the vehicle under simulated combat conditions. They timed the transition from water to land. They pushed both platforms to their mechanical limits and documented exactly where those limits were.

The SuperAV had one decisive advantage. It could carry 13 embarked Marines plus a crew of three. The Terrex 2 carried 11. In the Marine Corps, a rifle squad is 13. Carrying a full squad in a single vehicle was not a luxury. It was a doctrinal requirement. The ability to keep a squad together from ship to shore to objective without splitting them across multiple vehicles was a capability the Marines considered non-negotiable.

On June 19th, 2018, the Marine Corps announced its decision. BAE Systems and its Italian-designed SuperAV won the amphibious combat vehicle contract. The initial award was $198 million for 30 low-rate initial production vehicles with a potential total value of up to $1.2 billion for 204 vehicles.

Program Executive Officer for Land Systems, John Garner, described the selection as a best value determination. Technical performance was weighted more heavily than cost. The vehicle that best met the Marines’ requirements won, regardless of where the hull was designed. The vehicle itself was a masterpiece of practical amphibious engineering.

At its core was an eight-wheel drive system developed by Iveco called the H drive. Unlike a conventional drivetrain that routes power through a single axle or transfer case, the H drive powered each wheel independently through a hydraulic system that mimicked the redundancy of a tracked vehicle. If a wheel was destroyed by a mine blast, the remaining wheels continued to function.

The vehicle could literally drive on seven wheels. Power came from a six-cylinder Iveco Cursor turbocharged diesel engine producing 690 horsepower mated to a ZF seven-speed automatic gearbox. On paved roads, the amphibious combat vehicle could exceed 65 mph, roughly 20 mph faster than the vehicle it replaced.

On rough terrain, the independent suspension and central tire inflation system allowed it to cross ground that would stop most wheeled vehicles. In water, two rear-mounted hydraulically driven propellers pushed the vehicle at approximately six knots. It could swim up to 12 nautical miles from ship to shore and then continue for over 250 miles on land without refueling.

The transition from water to land required no transformation, no retracting components, no complex mechanical changeover. The vehicle simply drove out of the ocean onto the beach and kept going. This was the opposite philosophy of the failed expeditionary fighting vehicle, which had required an elaborate and unreliable transition sequence between its water jet and land drive modes.

Protection was where the amphibious combat vehicle made its most dramatic leap over the vehicle it replaced. The hull was shaped into a deep V designed specifically to deflect mine and improvised explosive device blast away from the crew compartment. Energy-absorbing seats were mounted to the troop floor, which itself was bolted to the seats rather than the hull, creating a suspended system that absorbed blast energy before it reached the Marines inside.

Modular applique armor could be added for different threat environments. An automatic fire suppression system and run-flat tires with central inflation completed the survivability package. The Marine Corps described the protection level as equivalent to an MRAP, the mine resistant vehicles that had saved thousands of lives in Iraq and Afghanistan.

Armament on the baseline personnel carrier variant came from the M153 Protector Remote Weapon Station, mounting either a .50 caliber M2 heavy machine gun or an MK19 40 mm grenade launcher. A more heavily armed variant, the ACV30, would later add a Kongsberg remote turret with a 30 mm Bushmaster II cannon and a coaxial 7.

62 mm machine gun. Now, before we go any further into where this vehicle has been deployed and what it has proven in the field, if you are enjoying this deep dive into amphibious engineering and military procurement, hit subscribe. It takes a second, costs nothing, and helps the channel grow. The vehicle that the amphibious combat vehicle was built to replace had already proven, in the most tragic way possible, why its retirement could not wait.

On July 30th, 2020, an assault amphibious vehicle carrying 16 personnel sank in approximately 385 ft of water off San Clemente Island, California, while returning to the amphibious transport dock USS Somerset. Eight Marines and one Navy hospital corpsman died. It was the deadliest assault amphibious vehicle accident in Marine Corps history.

The investigation that followed exposed a chain of systemic failure. The vehicle, a 36-year-old airframe, suffered a transmission failure that disabled its bilge pumps. Water flooded the troop compartment. Most of the embarked Marines had never completed underwater egress training because the base training pool was closed for repairs.

No safety boats were in the water during the transit. A rescue vehicle that attempted to reach the sinking platform actually collided with it. Multiple officers were relieved of command, including the battalion landing team commander and the commanding officer of the 15th Marine Expeditionary Unit.

A general officer was later removed from his post as Marine Corps Inspector General. The names of the fallen: Private First Class Bryan Baltierra, Lance Corporal Marco Baranco, Private First Class Evan Bath, Hospitalman Christopher Gnem, Private First Class Jack Ryan Ostrovsky, Lance Corporal Guillermo Perez, and their fellow service members became the most urgent argument for replacing the vehicle that had killed them.

The first 18 amphibious combat vehicles were delivered to the Marines in October 2020, just 3 months after the San Clemente disaster. An activation ceremony was held with the 1st Marine Division at Camp Pendleton on November 4th, 2020. Full-rate production was approved in December of that year. The assault amphibious vehicle was pulled from all waterborne operations and and never swim again, but the amphibious Combat Vehicle’s own path to operational readiness was not without setbacks.

In September 2021, all waterborne operations were suspended for approximately 4 months after a defect was discovered in the SEATOW quick-release mechanism, a towing component used during ship recovery. The fix required redesigning the tow rope system, which was completed by April 2022. Then, on July 19th, 2022, one Amphibious Combat Vehicle rolled over and another was disabled during high surf operations at Camp Pendleton.

All waterborne operations were suspended again. Open ocean operations resumed in September 2022 with a maximum wave height restriction of 4 ft, but surf zone operations remained restricted well into 2024. The most serious incident came on December 12th, 2023, when an Amphibious Combat Vehicle rolled over during ground movement at Camp Pendleton, killing Sergeant Matthew K.

Bilski, a 23-year-old vehicle commander from Royal Oak, Michigan, serving with the 15th Marine Expeditionary Unit. 14 other Marines were hospitalized. It was a sobering reminder that no vehicle, however advanced, eliminates the risk inherent in amphibious operations. Despite these setbacks, the Marine Corps pressed forward with deployment.

The logic was unforgiving. The Assault Amphibious Vehicle was gone. There was no fallback. The Amphibious Combat Vehicle had to work because there was nothing else. On March 19th, 2024, the 15th Marine Expeditionary Unit departed Southern California aboard the USS Harpers Ferry. On May 4th, 2024, at Oyster Bay in Palawan, the Philippines, during Exercise Balikatan, Amphibious Combat Vehicles conducted the first overseas live-fire waterborne gunnery exercise in Marine Corps history. Since the 2020 disaster, Marines drove the vehicles out of the well deck of a naval vessel, swam them to shore under their own power, transitioned to land, and engaged targets with the remote weapon station. Colonel Shawn Dinan, commanding officer of the 15th Marine Expeditionary Unit, described it as a proof of concept across the Marine Corps for successful employment of the vehicle in its intended environment. It was the moment the program stopped being a procurement decision and became an operational reality.

By mid-2024, vehicles had been fielded to the 3rd Marine Expeditionary Force in Okinawa, Japan, marking the first forward deployment of the platform to the Western Pacific. In August 2024, they made their Korean Peninsula debut during Exercise Ssang Yong. After a detailed hydrographic survey confirmed conditions suitable for amphibious operations, the amphibious combat vehicle was no longer a test article.

It was a deployed weapon system operating in the most contested theater on Earth. Compared against the vehicle it replaced, the amphibious combat vehicle represents a generational leap in every category except two. It is faster on land by roughly 20 mph. Its blast protection is incomparably superior, a V-hull versus a flat aluminum floor.

Its automotive reliability is modern rather than 1970s vintage. Its independent wheel drive offers redundancy that tracked assault amphibious vehicle never had. But it swims at approximately the same speed, around six knots, and it carries fewer Marines, 13 versus 21. Critics, including a prominent 2019 article in the United States Naval Institute Proceedings, argued that the Marines had spent billions to buy a vehicle that was no faster in the water than the one it replaced and still required ships to close within missile range of a hostile shore. The doctrinal debate remains unresolved. Against the failed Expeditionary Fighting Vehicle, the contrast is even more instructive. The Expeditionary Fighting Vehicle promised revolutionary capability at revolutionary cost. It delivered neither. The Amphibious Combat Vehicle promised proven capability at manageable cost. It delivered both. At roughly $6 to 7 million per vehicle, the Marines could buy almost four Amphibious Combat Vehicles for the price of a single Expeditionary Fighting vehicle, the

lesson was not that ambition is wrong. The lesson was that procurement programs that demand perfection across every parameter tend to deliver nothing, while programs that prioritize survivability, reliability, and affordability tend to deliver vehicles that actually reach the fleet.

The Italian heritage of the platform is no footnote. It is the through line of the entire story. Iveco Defense Vehicles, headquartered in Bolzano since 1937, when the facility was founded under the Lancia Veicoli Industriali brand to build military trucks, built Italy’s entire modern wheeled armor family. The B1 Centauro, an 8×8 wheeled tank destroyer with a 105-mm gun, entered service in 1991 and rewrote the rules for wheeled armored warfare.

It was exported to Spain and evaluated by the United States Army during the early Striker era. The Freccia infantry fighting vehicle, derived from the Centauro chassis, deployed to Afghanistan in 2010 carrying a Hitfist turret with a 25-mm cannon. The light multirole vehicle, known as the Lince, entered production in 2003 and has been sold to more than a dozen nations, with over 4,500 produced.

The same H drive system, the same engineering philosophy of wheeled redundancy and amphibious capability, runs through all of them and through the Super AV. These were not separate programs. They were iterations of a single industrial philosophy, refined over three decades, that prioritized wheels over tracks, reliability over complexity, and exportability over national exclusivity.

In July 2025, Leonardo agreed to acquire Iveco Defense Vehicles for 1.7 billion euros, consolidating Italy’s entire land systems capability under a single defense prime. The company that built the hull of the future American amphibious vehicle was now part of one of Europe’s largest defense conglomerates.

The approved acquisition objective now stands at 632 vehicles across four variants. 390 personnel carriers designated ACVP, carrying three crew and 13 Marines with the remote weapon station. 33 command variants designated ACVC, fitted with seven workstations, expanded communication suites, and additional battery power for extended operations.

34 recovery variants designated ACVR, equipped with winches and cranes capable of recovering vehicles weighing more than 30 tons in the field. And 175 of the up-gunned ACV-30 variant mounting the Kongsberg remote turret with the 30-mm Bushmaster II cannon and a coaxial 7.62-mm machine gun, carrying eight Marines instead of 13 to accommodate the turret and ammunition.

The first ACV-30 entered full-rate production in April 2025 under a contract worth $188.5 million. Kongsberg received a separate contract worth approximately $330 million to supply 175 turrets. The same platform has also been ordered by the Italian Navy with 36 vehicles designated VBA and by the Spanish Marines with 34 vehicles under the designation VACIM.

The Super AV is becoming the Western standard for amphibious armored warfare. 2009, a testing facility outside Bolzano, an armored box on eight wheels rolls into the water and floats. No one has ordered it. No contract demands it. No government requirement says it should exist. It is Italian. It is heavy. It looks like it should sink.

It is not the fastest vehicle in the water. It never was. It swims at the same six knots as the tracked vehicle it replaced, a vehicle designed in the 1960s. It is not the cheapest to produce at roughly six to seven million dollars per copy. It costs more than many armored vehicles that do not swim at all.

It cannot carry as many Marines as the Assault Amphibious Vehicle, 13 instead of 21. It has rolled in surf zones off Camp Pendleton. It has struggled with reliability metrics that the Pentagon’s own testers flagged as reaching only 27% of planned growth targets. Its suspension and steering subsystems have been the primary drivers of breakdowns.

It has cost a Marine his life on land, and yet it won. It beat every American design on the table. It beat a Singaporean platform backed by one of the largest defense contractors in the world. It replaced a vehicle that had been in service for over 40 years and had killed nine of its own in single afternoon off San Clemente Island.

It entered full-rate production faster than any major Marine Corps ground program in a generation. It deployed to the Pacific, to the Philippines, to Japan, and to Korea. It is being built in Pennsylvania, assembled in South Carolina, tested in California, and fielded to every Marine expeditionary unit in the fleet.

The Expeditionary Fighting Vehicle tried to do everything. It achieved nothing. The Amphibious Combat Vehicle tried to do enough. It achieved everything the Marines actually needed. 632 vehicles ordered. Three nations operating the same platform. An Italian hull carrying American Marines from ship to shore across the Pacific.

That is not irony. That is what happens when a military stops chasing perfection and starts buying what works.
