Report: delays impede hypersonic missile integration on US Navy's Zumwalt-class destroyers

The GAO said the US Department of Defense (DOD) is planning to invest at least US$50 billion into developing, testing, producing, and fielding CPS capability across several programs. While US Navy and US Army officials told GAO that they coordinate with each other, the services largely manage investment decisions for these programs separately, which contributes to inefficiencies and delays.

The GAO found that the DOD does not have a comprehensive strategy across all programs that would ensure that each program’s investments achieve CPS’s common objectives. Without a comprehensive investment strategy that includes more formal coordination, the army and navy are not well-positioned to make timely and efficient investments in key areas, such as addressing shortfalls on their shared production lines or ensuring the economical sustainment and performance of the DDG 1000.
