ARLINGTON, Va. — The U.S. Marine Corps has halted waterborne operations of its new amphibious armored vehicle pending resolution of a mechanical problem. 

Maj. Jim Stenger, Marine Corps spokesperson, issued the following statement on Sept. 3: 

“Out of an abundance of caution, the Marine Corps has suspended waterborne operations of the Amphibious Combat Vehicle [ACV] after identifying an issue with the towing mechanism. The Marine Corps is working on identifying and fixing the root cause of the problem. Realistic training is a vital component of readiness, and the Marine Corps is committed to ensuring Marines train under the safest conditions possible; this includes ensuring the functionality of vehicles and equipment.” 

The ACV, built by BAE Systems, is replacing the AAV7 assault amphibious vehicle in Marine Corps service.
