US Navy stealth destroyer Zumwalt completes post-refit builder's trials

Shortly after arrival, the ship was moved onto land where the Ingalls Shipbuilding team incorporated technology upgrades. These included integrating the CPS weapon system and replacing the ship's original twin 155mm main guns with new missile tubes.

In December 2024, Zumwalt was launched and underwent additional preparations to ensure her operational readiness with the new system.

Sister ship USS Lyndon B. Johnson is also undergoing CPS weapon system integration while USS Michael Monsooris scheduled to receive the CPS system during a future refit.

CPS is a conventional, boost-glide hypersonic weapon system. Each CPS missile includes a two-stage solid rocket motor booster and a common hypersonic glide body containing a kinetic energy projectile warhead.
