GAO: Navy Zumwalt Conventional Prompt Strike hypersonic upgrades ~24 months behind; manufacturing/quality issues flagged
A Government Accountability Office review says the U.S. Navy is roughly 24 months behind schedule on installing the Conventional Prompt Strike hypersonic capability on three Zumwalt-class destroyers, tied to ship-integration and weapon-system development challenges. GAO also warns of manufacturing and quality-control problems affecting planned production rates for the Navy’s hypersonic missile effort.
