The Navy has issued letters of censure to three Marine and two Navy officers in connection with the sinking of an amphibious assault vehicle off the Southern California coast in 2020 that killed eight Marines and a sailor.

Navy Secretary Carlos Del Toro, in a statement Monday, faulted the officers for “inadequate leadership and execution of their oversight duties.” Censure letters are put in service members' personnel files and are often career-ending for military officers, usually preventing them from further promotion or other progress.

A Marine Corps investigation found that inadequate training, shabby maintenance and poor judgment by leaders led to the July 30, 2020, sinking of the amphibious assault vehicle in one of the deadliest Marine training accidents in decades.


The vehicle — a kind of seafaring tank — had 16 people aboard when it sank rapidly in 385 feet (117 meters) of water off the coast of San Clemente Island. Seven Marines were rescued as the vessel was returning to a Navy ship on a training exercise.

Del Toro said Lt. Gen. Joseph Osterman, who was commander of the 1st Marine Expeditionary Force, failed to recognize and address the risks of the exercise, including training and safety failures. He said Osterman, who is now retired, also didn't recognize the impact of COVID-19 on the exercise, which forced commanders to adjust the timing and compress the schedule.

Del Toro said Col. Christopher Bronzi, who was serving as commander of the 15th Marine Expeditionary Unit, either knew or should have known that pre-deployment waterborne training was not finished and that the amphibious vehicles were “in a degraded state of readiness."

“The investigations revealed critical safety measures were not implemented during the mishap,” said Del Toro. “Accountability for these failures rests with you.”

In a letter of censure to Navy Capt. Stewart Bateshansky, Del Toro pointed to “gaps and seams” in the planning of the exercise. He said that while Bateshansky, who was commander of the amphibious task force for the exercise, reduced the complexity of the planned event, his instructions to subordinate commanders weren't clear about the ability to abort or delay the launch from the beach.


Navy Capt. John Kurtz, who was the commanding officer on the USS Somerset, was censured for failing to ensure the safe operation of the amphibious vehicles.

Del Toro said that while “the investigation did not establish that any of USS Somerset's actions or inactions caused the sinking,” he said that Kurtz' crew “was poorly informed of the risks and measures required” for safe operation of the amphibious vehicles.

He said Lt. Col. Keith Brenize, who was the commander of the 3rd Assault Amphibian Battalion, failed to ensure that the platoon was trained for the deployment and that the vehicles were operationally sound. “While no single decision or act led to this mishap, your decisions and acts set the conditions for this mishap to occur,” Del Toro said.

Eric Dubin, lawyer for the families of seven of the troops killed, said in a statement that his clients were glad to see the military taking action against the leadership involved.

“We are pleased the military continues to investigate this deadly tragedy and find accountability and answers,” Dubin said in a statement. But he added, “unfortunately our clients are stuck behind the roadblock that is the Feres Doctrine," referring to the legal theory that dictates that troops cannot sue the federal government for injuries sustained while serving in the military, with the exception of medical malpractice cases.

The Marines use the amphibious vehicles to transport troops and their equipment from Navy ships to land. The armored vehicles outfitted with machine guns and grenade launchers look like tanks as they roll ashore for beach attacks, with Marines pouring out of them to take up positions.

KPBS has created a public safety coverage policy to guide decisions on what stories we prioritize, as well as whose narratives we need to include to tell complete stories that best serve our audiences. This policy was shaped through months of training with the Poynter Institute and feedback from the community. You can read the full policy here.
