Most notoriously, Zumwalt is built around the Advanced Gun System, since Congress is obsessed with naval shore bombardment. (See also how they kept Iowa in service decades after it was obsolete) But... >A total of six of the systems were installed, two on each of the three Zumwalt-class ships. The Navy has no plans for additional Zumwalt-class ships, and no plans to deploy AGS on any other ship. AGS can only use ammunition designed specifically for the system. Only one ammunition type was designed, and the Navy halted its procurement in November 2016 due to cost ($800,000 to $1,000,000 per round), so the AGS has no ammunition and cannot be used. The Navy will remove the AGS from the ships in 2023. https://en.wikipedia.org/wiki/Advanced_Gun_System https://en.wikipedia.org/wiki/Advanced_Gun_System A complete dead end, a decade spent doing nothing. Meanwhile, China is launching a dozen guided missile destroyers a year.
