  • The first Navy warships to carry hypersonic missiles will be the Zumwalt destroyers.
  • Initial expectations were the weapon’s deployment would start with Virginia-class submarines.
  • The Navy is expected to start fielding it aboard its vessels in 2025, the Navy’s top officer says.

The first US 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.

Although 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 intends to start with the Zumwalts.

“Our biggest [research and development] 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 will 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 $1 million 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 currently 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 military successfully flight tested the glide body in March 2020.

A common hypersonic glide body (C-HGB) launches from Pacific Missile Range Facility, Kauai, Hawaii, at approximately 10:30 p.m. local time, March 19, 2020, during a Department of Defense flight experiment.

A hypersonic glide body is the part of a hypersonic weapon that carries the warhead. Launched using a conventional rocket booster, the glide body will eventually separate 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.

Because these weapons are difficult to defeat, hypersonic missiles have become a key area of strategic competition between the US and rivals China and Russia.

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 them onto the destroyers, which don’t currently vertical-launch-system cells large enough for them.

The Navy sent out a solicitation in mid-March asking industry partners for solutions on how the Zumwalts could be reconfigured to carry the larger hypersonic missiles. The sources-sought notice is looking at an advanced payload module capable of carrying hypersonic missiles in a “three-pack configuration.”

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.

The US Navy’s giving a stealth Zumwalt destroyer control of drone ships and aircraft for a future naval combat experiment

  • A Zumwalt-class destroyer will command manned and unmanned assets in an exercise next month.
  • The unmanned assets will include UAVs like the MQ-9 and Fire Scout, as well as surface vessels.
  • The Navy will use the Fleet Battle Problem exercise to explore possibilities for the future force.

The US Navy will give one of its advanced Zumwalt-class destroyers control of multiple unmanned systems during an upcoming exercise exploring possibilities for future naval warfare.

During next month’s Fleet Battle Problem exercise in the Pacific, the USS Michael Monsoor (DDG-1001) will command both unmanned surface vessels and aircraft as the Navy looks at which elements of a potential future force “will have the greatest impact on increasing the fleet’s lethality,” a Navy official said in a statement first reported by USNI News.

Navy spokesman Lt. Col. Tim Pietrack, citing the demands of the Unmanned Campaign Framework, said that “it is imperative that we understand what our future force will need to operate both in day-to-day competition as well as high-end combat.”

The exercise, which will take place in the 3rd Fleet area of responsibility under the supervision of US Pacific Fleet, “will incorporate many unmanned capabilities and unmanned capability enablers,” Pietrack said.

He said that during the exercise, the Michael Monsoor “will use the ship’s unique capabilities to command and control manned and unmanned forces to conduct long-range, multi-domain fires.”

The unmanned assets expected to participate in the complex exercise include the unmanned surface vessels Sea Hunter and Sea Hawk and the MQ-8B Fire Scout and MQ-9 Sea Guardian unmanned aerial vehicles.

Sea Hunter, an entirely new class of unmanned sea surface vehicle developed in partnership between the Office of Naval Research (ONR) and the Defense Advanced Research Projects Agency (DARPA)

The MQ-9 Sea Guardian drone serves as a scout aircraft, as well as an anti-submarine warfare asset, while the Fire Scout, an unmanned helicopter that will operate from a Littoral Combat Ship during the exercise, can conduct both reconnaissance and strike missions.

During next month’s exercise, the Sea Hunter, which has participated in past exercises, and the newer Sea Hawk will support manned units in an anti-submarine role while also providing maritime domain awareness.

Pietrack said that “through operational scenarios, what we learn from this event will provide pertinent and timely input to the Naval Research Enterprise and the acquisition community to better inform unmanned system development moving forward.”

The Navy has shown increasing interest in unmanned systems, which are expected to be a critical part of the future fleet.

Looking at the competition with China, which has the world’s largest naval force, the Pentagon proposed in October a 500-ship Navy consisting of as many as 240 unmanned or optionally-manned vessels, both surface ships and undersea assets, that could conduct resupply, surveillance, mine, and strike missions, among other operations.

It remains to be seen if such a force will become reality, but the interest in using unmanned systems to augment the force is there.

For the Michael Monsoor, the second of the three stealthy Zumwalt-class destroyers, the upcoming Navy exercise is an opportunity to explore some potential options for the class amid uncertainty about the role the advanced vessels might play in combat.

Commanding multiple unmanned systems in an exercise of this scale will be a first for the ship.

uss zumwalt

The Navy commissioned the Zumwalt, the first of a new class of destroyers, in 2016, but the warship was not delivered to the service with a working combat system until April.

Among problems like cost overruns and major delays, a big problem with the Zumwalt was the two 155 mm guns of the Advanced Gun System.

When the Navy reduced its order for Zumwalt-class ships from roughly three dozen to just three, the cost of the rounds for the guns shot up. A single Long-Range Land Attack Projectile was going to cost almost $1 million.

The unacceptable price of the gun’s ammunition was just one of the problems with the guns that forced the Navy to reevaluate the combat system and shift the ship’s mission from a naval fire support role to maritime strike.

The Zumwalt fired its 30 mm Mk 46 MOD 2 Gun Weapon System for the first time in May and first launched a SM-2 missile from its Mk 57 Vertical Launching System in October.

More recently, there have been discussions about eventually arming the vessels with hypersonic missiles.
