摘要

In January, the U.S. Defense Department announced plans to fund a Darpa-Air Force-Navy technology demonstration program aimed at developing critical sixth-generation fighter capabilities. The Aerospace Innovation Initiative will develop common avionics, subsystems, engine technologies and other components that could be used on separate Air Force and Navy airframes. This announcement is an encouraging sign that the Pentagon is adopting a cost-effective strategy for joint fighter programs. However, it will need to remain vigilant to avoid the pitfalls that have caused previous joint fighter programs to fall short of hoped-for cost savings and to accept unwelcome design compromises. The Pentagon has pursued several joint development programs-in which two or more services are significantly involved in all stages of the acquisition and operational phases-for fighters and other aircraft over the past 50 years, particularly during periods of great budgetary pressure. The reason is simple: Joint fighter programs appear to offer the prospect of life-cycle cost savings by eliminating duplicative research, development, testing and evaluation, and by achieving economies of scale in production, operations and support.
