Development Direction of Reliability-based ROK Amphibious Assault Vehicles

Abstract

A plan for the development of reliability-based ROK amphibious assault vehicles is proposed. By analyzingthe development case of the U.S. EFV, considerations for the successful development of the next-generationKorea Forces amphibious assault vehicle are presented. If the vehicle reliability can be improved to the level ofthe fourth highest priority electric unit for power units, suspensions, decelerators, and body groups, which havethe highest priority among fault frequency items, a system level MTBF of 36.4%↑ can be achieved, and theoperational availability can be increased by 3.5% . The next-generation amphibious assault vehicles must fulfillcertain operating and performance requirements, the underlying systems must be built, and sequencing of thehybrid engine and the modular concept should be considered. Along with big-data- and machine-learning-basedfailure prediction, machine maintenance based on augmented reality/virtual reality and remote maintenanceshould be used to improve the ability to maintain combat readiness and reduce lifecycle costs.
