The company will supply the ACVs under the low-rate initial production (LRIP) phase of the programme.
The latest production deal will now bring the total ACV order from the USMC to 116, moving the programme closer to full-rate production.
In October last year, BAE Systems won a $120m contract from the USMC to continue the third LRIP lot of ACVs.
USMC’s new contract comes as it intends to replace its legacy fleet of BAE Systems-built assault amphibious vehicles, which have been in service for decades.
A mobile, survivable and adaptable platform, ACV is used to carry out ship-to-shore operations, bringing improved combat power to the battlefield.
Since 2018, the company has been in low-rate production on the personnel carrier variant in the ACV family.
The ACV family is envisioned to comprise additional variants, including command and control, 30mm medium calibre turret, and recovery versions.
BAE Systems amphibious programmes director John Swift said: “The ACV provides the most survivable and mobile amphibious vehicle to the US Marines Corps for supporting the warfighters’ ability to successfully execute their unique expeditionary missions.
“This award further demonstrates our commitment to that mission, it’s an important milestone for the programme and represents a major step toward full-rate production.”
BAE Systems is conducting ACV production and support at its facilities in Virginia, California, Michigan, South Carolina, and Pennsylvania.
The company rolled out the first of 16 ACV 1.1 prototypes to the USMC in December 2016.
