In March 2021, the Navy solicited information from the industry on how to reconfigure the Zumwalt-class ships to host Long-Range Hypersonic Weapons (LRHW). Since they would be too large to fit in the VLS tubes, it has been suggested that the two AGS, having no use since the cancellation of their ammunition, could be replaced with three-pack advanced payload modules to fulfill a conventional prompt strike deterrence role. The Navy will request FY 2022 funding to replace the 155 mm AGS turrets with Advanced Payload Modules for the Conventional Prompt Strike (CPS) hypersonic missile. The conversion would be part of the DDG 1000 Dry-Docking Selected Restricted Availability (DSRA) beginning FY 2024. The LRHW is also slated for Block V Virginia-class attack submarines (SSN). The larger tubes for the VLS will be based upon the Virginia Payload Module (VPM) used in the Virginia SSNs. The first Zumwalt-class destroyer will be ready to test the CPS in 2025. In mid-August 2023 the lead vessel arrived at Pascagoula to have the AGS replaced by the Hypersonic missile tubes and the integration of the new weapons system.
