US Marine corps approved a low-rate initial production of the Amphibious Assault Vehicle Survivability Upgrade program

The Marine Corps approved the Amphibious Assault Vehicle Survivability Upgrade (AAV-SU) program to begin low-rate initial production (LRIP), with the program executive officer for land systems signing a Milestone C decision on Aug. 17 and the program manager awarding SAIC funding for 21 vehicles Tuesday, Advanced Amphibious Assault Program Manager Col. Wendell Leimbach told USNI News.
     
     
SAIC delivered its first of 10 engineering and manufacturing development vehicles in March 2016, and the Marine Corps has spent the last year and a half putting these vehicles through developmental tests and operational assessments to ensure they meet all the criteria for “making the vehicle relevant to the modern battlefield.” Those upgrades – which SAIC performed on legacy AAVs that first went into production 45 years ago – include enhanced survivability through added armor and blast-mitigating seats, and an improved engine and suspension to allow equal mobility as the legacy AAVs despite the added weight. Delivery of personnel AAV-SUs will begin in the second quarter of next year, Leimbach said. Those vehicles would then be put into a reliability growth testing program, where potential improvements will be identified and either fed back into the design or held onto for the Marines to modify at a later date.

Developmental testing took place at Aberdeen Test Center in Maryland and the Amphibious Vehicle Test Branch (AVTB) at Camp Pendleton, and the operational assessment took place at Marine Corps Air Ground Combat Center Twentynine Palms and AVTB. Throughout the testing, which wrapped up in June, the program office learned a lot of lessons that were fed back into the design. For example, Leimbach said, adding new survivability features into a fixed vehicle hull size “constrained the internal volume” of the vehicle. The award to SAIC includes funding to overhaul 18 personnel-variant vehicles and three command and control-variant vehicles. The Marine Corps originally planned to only upgrade the personnel-variant vehicles but has since decided to include a few dozen command and control vehicles as well.
