In June 2018, the Marine Corps announced they had selected the BAE Systems/Iveco wheeled SuperAV for the Amphibious Combat Vehicle (ACV) program to supplement and ultimately replace the AAV.

The U.S. Marine Corps became interested in replacing the LVTP-5 due to its limited range, slow water speed and the difficulty of maintaining the aging platform.

[8] Marine Corps and SAIC officials unveiled the AAV SU prototype in January 2016, with survivability enhancements including replacing the angled EAAK with 49 advanced buoyant ceramic armor panels, a bonded spall liner, armor-protected external fuel tanks, an aluminum armor underbelly providing Mine Resistant Ambush Protected (MRAP)-equivalent blast protection, and blast mitigating seats as well as a more powerful engine, new suspension system, and increased reserve buoyancy.

[12][13] In 2021, the United States Marine Corps started to install M153 Common Remotely Operated Weapon Stations (CROWS) to their AAVP-7A1s.

[14] The M153 Common Remotely Operated Weapon Station (CROWS) is a stabilized mount that contains a sensor suite and fire control software.

As Marines became increasingly involved in hostilities, several vehicles sustained minor damage from shrapnel and small arms fire.

On October 25, 1983 U.S. Marine LVTP-7s conducted a highly successful amphibious landing on the island of Grenada as part of Operation Urgent Fury.

[17][18][19] On 3 August 2005, 14 U.S. Marines and their Iraqi interpreter were killed when their AAV struck a roadside bomb in the city of Haditha in the Euphrates river valley in western Iraq.

[21][22] Eight U.S. Marines and one U.S. Navy sailor died on 30 July 2020, when their AAV sank in the Pacific Ocean off the coast of San Clemente Island, California, during a training exercise, ahead of an upcoming deployment.

[23] As a result of the incident, on 15 December 2021 the U.S. Marine Corps announced that it has banned its fleet of amphibious armored personnel carriers from maritime operations except in emergencies.

[26] However, in January 2011, United States Defense Secretary Robert Gates announced plans to cancel the Expeditionary Fighting Vehicle.

In June 2018, the Marine Corps announced they had selected the BAE Systems/Iveco wheeled SuperAV for the Amphibious Combat Vehicle (ACV) program to supplement and ultimately replace the AAV.

The system consists of an actual surplus turret mounted with ISMT (Indoor Simulated Marksmanship Trainer) weapons firing on a projected screen displaying the VIRTE Virtual Environment.
