The Marine Corps put an assault amphibious vehicle (AAV) back in the water this week for the first time since one sank last summer, killing nine service members, Marine Corps officials told Insider Thursday.
Last July, an AAV assigned to Bravo Company, Battalion Landing Team 1st Battalion, 4th Marines, part of the 15th Marine Expeditionary Unit, sank off the coast of California as it returned to the amphibious transport dock USS Somerset from San Clemente Island.
The mishap vehicle was carrying three AAV crewmembers, 12 Marines, and one Navy corpsman. Eight embarked Marines and the Navy sailor died, making this incident the deadliest AAV training accident in the vehicle’s history.
“Out of precaution, before we understand what caused this, we are pausing the waterborne operations for amtracs,” Marine Corps Commandant Gen. David Berger said the day after the accident, as the Corps was still searching for the bodies of the deceased, considered only missing at that point.
A recently released investigation into this tragic disaster revealed it was preventable. The accident was caused by a series of human and mechanical failures. Specifically, the vehicle was improperly maintained, training was inadequate, and critical safety procedures were not followed.
Responsibility for the deadly accident was placed on leaders across the chain of command, from the 15th MEU commander down to the vehicle commander. Disciplinary action has already been taken against some unit commanders.
This week, after an eight-and-a-half-month pause, AAVs again started splashing, but with conditions, Corps officials said.
Last Friday, the Marines published requirements for the resumption of AAV waterborne operations, Marine Corps spokesperson Capt. Andrew Wood told Insider on Thursday.
No movement between Navy ships and the shore is permitted, and shore-to-shore movement over water is only permitted once a unit has completed 18 tasks.
Wood said that the tasks “cover a variety of requirements from ensuring training and qualifications for crew and embarked personnel, personnel are properly equipped, vehicles have passed required inspections, and operations are conducted with safety boats, sea state assessments, and positive communication.”
For instance, everyone riding in an AAV has to have completed the full underwater-egress training program, to include training on the Waterborne Egress Capability breathing bottles.
As Insider previously reported, the supplemental emergency breathing devices are being put back in the vehicles after they were removed in 2015 to cut costs. All embarking personnel must be equipped with these devices.
These requirements also apply to the new amphibious combat vehicles that are being introduced as replacements for the AAVs that first entered service in the 1970s.
At the moment, the California-based 1st Marine Division is believed to be the only unit to have met the requirements, division spokeswoman Maj. Kendra Motz told Insider. She said the first AAVs splashed Tuesday.
