The US Navy's Zhumwalt missile destroyer has delayed its hypersonic missile upgrade plan due to maintenance issues.
According to the news website of the American Naval Society on July 31, the USS Jumwalt destroyer set sail from the San Diego Naval Base on the 27th and headed to the Huntington Ingalls Shipyard in Pascagoula, Mississippi for modification, with a focus on installing a conventional fast strike hypersonic missile. However, due to a sudden malfunction, repairs had to be carried out at the shipyard in San Diego.
The Zhumwalt destroyer was launched in 2013 at a cost of approximately $4.4 billion, making it the most expensive destroyer by the US Navy to date.
According to reports, once it arrives at Ingalls Shipyard, the ship's 155mm advanced artillery system will be dismantled for the installation of four missile launchers with a diameter of approximately 220 centimeters to accommodate hypersonic missiles. According to reports, each missile launcher will accommodate 3 missiles, and a Jumwalt class destroyer can carry up to 12 hypersonic missiles. The Navy plans to upgrade the other two ships of this class in Ingalls - the second ship "Michael Monsur" and the third ship "Lyndon Johnson".

The US Navy plans to deploy hypersonic weapons on the Jumwarts by 2025, but due to delayed testing of conventional rapid strike hypersonic missiles, deployment may not proceed as scheduled. If the hypersonic missile is not ready to be integrated into the Jumwalt during the maintenance period mentioned above, the Navy may have to extend the duration of the planned maintenance cycle or wait for the next scheduled cycle to integrate the system onto the ship.
The conventional rapid strike hypersonic missile is a thrust glide hypersonic missile jointly developed by the US Navy and Army. The US Navy also plans to deploy this weapon on the Virginia Block5 nuclear submarine by 2029.
The Jumwalt class destroyer is currently the most advanced destroyer in the United States, with good stealth performance and strong ground and air strike capabilities. The United States once planned to replace the active Arleigh Burke class destroyers with the Jumwalt class, but due to the huge construction and difficulty of the former, as well as high maintenance costs, the construction plan for 32 ships was ultimately reduced to 3. In September 2016, the Jumwalt was found to have malfunctioned on the eve of its sea trial, with water outside entering the engine lubrication system acting on one of the ship's propeller shafts.
