GAO: Navy Zumwalt-CPS hypersonic installation running ~24 months behind; Lockheed missile-building at scale plagued by manufactu

A Government Accountability Office review found the U.S. Navy’s effort to upgrade three Zumwalt-class destroyers with the Conventional Prompt Strike (CPS) hypersonic missile capability is about 24 months behind schedule. GAO also cited manufacturing and quality-control challenges preventing the program from reaching planned production rates, raising concerns about wasted money and time within the broader $50B-plus hypersonic push.

Briefing

What Hype is tracking

GAO reports the Navy is roughly two years behind on Zumwalt-CPS integration, directly affecting timeline credibility for a high-cost element of a $50B-plus hypersonic effort.
Auditors point to manufacturing and quality-control problems constraining planned production rates, elevating schedule slip and lifecycle cost risk for both the ships and the developing missile.
The findings underscore program-execution risk that could drive additional oversight and reprioritization across U.S. hypersonic modernization—beyond a single ship or vendor deliverable.
