Hypersonic Missile Project Two Years Behind Schedule for Zumwalt Destroyers

The U.S. Navy's ambitious plan to equip its three remaining Zumwalt-class destroyers with hypersonic missiles is facing significant delays and cost overruns, according to a recent report by the Government Accountability Office (GAO). The project, aimed at enhancing naval capabilities through the installation of Conventional Prompt Strike (CPS) hypersonic missiles on these advanced warships, has encountered numerous technical challenges and coordination issues between the Navy and Army.

The CPS missile program was initiated in 2022 to provide a new mission for the Zumwalt-class destroyers, which were originally designed with fewer ships due to escalating costs and capability concerns. The initial plan called for arming these vessels with boost-glide hypersonic missiles capable of striking targets thousands of miles away within half an hour. However, the integration process has proven more complex than anticipated.

According to GAO findings, the Navy is currently two years behind schedule in installing the CPS missiles on the Zumwalt-class destroyers. The first flight tests, originally scheduled for 2025, have been postponed until at least 2027. This delay is attributed to a combination of technical issues with both the ships and the missiles themselves.

One significant challenge identified by GAO involves the unique systems on the Zumwalt-class destroyers, which include advanced radar, combat, and network capabilities that are costly and difficult to maintain. Additionally, these ships have faced reliability issues with their power systems and difficulties in obtaining spare parts, further complicating efforts to integrate new weapon systems.

The CPS missile itself has also encountered production challenges. Lockheed Martin, the primary contractor responsible for producing the missile body, is grappling with issues such as insufficient production capacity and substandard parts. The factory's current rate of six or seven missiles per year falls short of the desired 12, leading to delays in meeting operational requirements.

Moreover, there are concerns about the complexity of the CPS missile production process, which relies on detailed engineering specifications that may be too intricate for newer workers without extensive experience. This has led to inefficiencies and further delays in ramping up full-scale production.

Coordination between the Navy and Army has also been a point of concern. Although both branches are working on variants of the same CPS missile system—naval-based for the Zumwalt-class destroyers and land-based for the Army—the two services have not fully aligned their development and procurement strategies. This lack of coordination could potentially lead to additional delays and inefficient use of taxpayer funds.

Despite these challenges, there have been some successful flight tests conducted from land facilities, demonstrating the potential capabilities of the CPS missile system. However, addressing ongoing technical issues and improving production efficiency remains crucial for the program's success.

The delays and cost overruns associated with this project underscore broader challenges in developing advanced military technologies that require extensive integration across different platforms and services. As the U.S. continues to invest heavily in hypersonic capabilities, resolving these issues will be essential for maintaining a competitive edge in future conflicts.
