Marine Corps adjusts interim guidance for ACV waterborne operations following training incident
14 Oct 2022

Following a training incident, the Marine Corps has adjusted Amphibious Combat Vehicle waterborne operations guidance; ceasing water operations involving surf zone transit to allow for additional testing and evaluation. 

On Oct. 13, 2022 at approximately 7:45 p.m. PST, an Amphibious Combat Vehicle assigned to Assault Amphibian School was conducting normal scheduled training operations when it rolled over in the surf zone after a reported mechanical malfunction near Camp Pendleton, CA. Of the three crew members inside the vehicle, none sustained injuries or required medical attention. The incident is currently under investigation. 

“We’re taking a deliberate and methodical approach to fielding this platform,” said Lt. Gen. David H. Furness, deputy commandant for Plans, Policies, and Operations. “This adjustment to current guidance ensures our Marines have the ability to safely train and maintain proficiency with the platform while we work to conduct additional testing.” 

Suspension of ACV surf zone transit will remain in effect until additional testing data can be collected and analyzed. In support of this, surf zone operations for Amphibious Vehicle Testing Branch-sponsored testing is authorized.
