AAV7 amphibious assault vehicles have been successfully operating for years.

On July 30, 2020, an AAV7 belonging to the US Marine Corps was sunk near San Clemente Island in Southern California. The exact location of the platform that took water for an unknown reason and was buried in the ocean was determined. The platform, which is detected about 117 meters deep off the San Clemente Island, is planned to be rescued in the coming days. The US Navy HOS Dominator ship is carrying out work in the area for a sailor on board and the dead bodies of the seven Marines to pull out

While starting a preliminary investigation about the accident, it was announced that the exact cause could only be determined after the vehicle was removed from its location. The United States has announced that it has stopped all AAV7 operations until a second order in the process of preparing the accident report.

AAV7s, which can reach land with water jets by sea from amphibious ships and serve as tracked armoured personnel carriers, have the capacity to carry 21 personnel as well as three crew members. The platform, which can continue its duty under the conditions of Sea Condition 5, weighs 29.1 tons.
