Abstract
Joint, in which multiple military services cooperate to achieve specific objectives, was also implemented in equipment acquisitions, with the expectation that it would eliminate duplication of projects between services and reduce costs by achieving economies of scale. However, in the United States, integration programs such as the integrated fighter program in the 1960s and later failed to achieve cost reductions. However, in the United States, joint programs such as the Joint Fighter Program in the 1960s and later did not achieve cost reductions.
This study examines the limitations of joint acquisition by comparing and analyzing the US Joint Fighter and Unmanned Aerial Vehicle programs, and verifies what factors hinder cost reduction and whether it is possible to achieve cost reduction.
In Japan, “Defense Buildup Program” indicates that concentrated investment will be made in equipment and technology fields based on an Integrated Equipment System. However, in order to avoid unnecessary cost increases, it is necessary to conduct sufficient prior verification to determine whether the equipment is suitable for joint acquisition.
