The first U.S. Navy warfighting vessels to be armed with hypersonic missiles will be the stealth Zumwalt-class destroyers, the service’s top admiral said, according to USNI News.
While the Navy was expected to field hypersonic weaponry on its cruise-missile submarines first, Chief of Naval Operations Adm. Mike Gilday said at a Center for Strategic and Budgetary Assessments event Tuesday that the service intended to start with the Zumwalts.
“Our biggest R&D effort is in hypersonics — to deliver that capability in 2025 on a surface ship and then on Block V [Virginia-class] submarines,” Gilday said, adding that fielding hypersonic weaponry aboard the Zumwalt-class destroyers would be an “important move” toward turning these ships into strike platforms.
The Zumwalt-class destroyers were designed to fight in littoral waters, carrying out land-attack and naval-fire support missions. Their primary weapon was to be the Advanced Gun System, consisting of a pair of 155 mm guns.
But a reduction in the size of the class from a few dozen ships to just three caused the cost of the Long Range Land Attack Projectile to jump to almost one million dollars a round, forcing the Navy to reevaluate its armaments and missions.
The Navy’s three Zumwalt-class destroyers — the USS Zumwalt, USS Michael Monsoor, and the future USS Lyndon B. Johnson — are expected to be blue-water surface-warfare and naval-strike platforms instead.
The hypersonic missile that the Navy is developing is the Conventional Prompt Strike weapon, which uses the Common Hypersonic Glide Body that the Army and Navy are working together to develop.

The hypersonic missile that the Navy is developing is the Conventional Prompt Strike weapon, which uses the Common Hypersonic Glide Body that the Army and Navy are working together to develop.
A hypersonic glide body is the part of a hypersonic weapon that carries the warhead. Launched using a conventional rocket booster, the glide body eventually separates from the rocket and continues on to the target.
After separation, the glide body is no longer able to accelerate, but it retains the ability to maneuver.
While hypersonic weapons have the ability to fly at speeds of at least Mach 5, it is their maneuverability that makes them particularly dangerous. Modern air- and missile-defense systems are not designed to counter this type of threat.
Before the Navy can arm its Zumwalt-class destroyers with these weapons, it needs to not only finish developing the weapon but also figure out how to integrate it on the destroyers, which don’t have vertical-launch-system cells large enough for them.
Speaking Tuesday, Gilday also expressed interest in using the substantial power-generation capabilities of the Zumwalt-class destroyers to support directed-energy weaponry for defense against emerging threats.
