• China's new Type 055 cruiser is its most modern and powerful surface combatant.
• The ship China labels as a destroyer is so large it compares more to US cruisers.
• China is building these ships fast while the US sunsets most of its aging cruisers.

China's navy has a menacing new addition to its naval fleet: the Type 055 class guided missile destroyer.

The destroyer is the most modern and potent surface combatant in China's navy, officially known as the People's Liberation Army Navy. Designed for multiple missions and fitted with a massive arsenal and advanced electronics, it is an apex predator in the PLAN's growing fleet meant to protect China's carriers from harm.

The class is so daunting and capable that the US Department of Defense classifies it as a cruiser. Many observers compare it to the US Navy's own cruisers, which have performed a similar role.

"Depending on your criteria, the Type 055 is the best or second-best surface combatant in the world," Chris Carlson, a retired US Navy captain and naval analyst told Business Insider.

And while the US Navy seeks to divest from its aging cruiser fleet, China is expanding its fleet at a breakneck pace.

Type 055 'Renhai'

China's desire for a massive surface combatant dates back to the 1960s. China initiated an "055" program in the mid-1970s, then canceled it in 1983 due to weaknesses in its industrial base and technological know-how.

Three decades later, however, China's booming economy enabled its shipbuilding industry to become the largest in the world. It emphasized modernizing the navy and building or acquiring fleet oilers, nuclear submarines, guided missile warships, aircraft carriers, and more.

The keel of the first Type 055, Nanchang, was laid in December 2014, just three months before the keel of China's first domestically built carrier, Shandong, was laid.

When Nanchang was commissioned in 2020, it made the class a force to be reckoned with. Measuring 590 feet long and displacing 12,000-13,000 tons, it is the largest class of surface combatant China has ever built.

Each Type 055, which NATO classifies as the Renhai-class, is fitted with 112 vertical launch system (VLS) cells, which launch missiles. Sixty-four cells are positioned forward of the bridge in an 8x8 configuration and 48 are located aft in a 6x8 configuration. These VLS cells have both cold and hot launch capability, enabling them to field a more diverse missile arsenal; in a cold launch, a missile is ejected from the cell via pressurized gas before its engine fires.

That arsenal includes YJ-18 anti-ship cruise missiles, CJ-10 land-attack cruise missiles, and HHQ-9 surface-to-air missiles (SAMs), which have ranges of around 335 miles, 497 miles, and 124 miles, respectively. The class may also be able to carry Yu-8 anti-submarine missiles.

In 2022, China tested a cold launch of a YJ-21 hypersonic missile from a Type 055's VLS cells. The missile reportedly has an approximate range of 932 miles, a cruising speed of Mach 6, and a terminal speed of Mach 10, which makes it challenging to intercept.

The Type 055 also features a single box launcher with 25 HHQ-10 short-range SAMs, four Type 726 defensive launchers capable of launching chaff, flares, and decoys, 2 triple-tubed torpedo launchers with Yu-7 torpedoes, a single 11-barelled H/PJ-11 Close-in weapon system (CIWS), and a H/PJ-38 130 mm naval gun.

At the stern, a helicopter deck and hangar can house two helicopters capable of tracking submarines and helping with logistics.

The Type 055 is also brimming with modern radars, sensors, and other electronics. This includes four Type 346B Dragon Eye S-band active electronically scanned array (AESA) radars mounted on the superstructure and four X-band radars housed in an integrated mast, making it the first Chinese warship with dual-band planar radar arrays. Its hull-mounted sonar can be enhanced by towed active array sonars.

With its arsenal and sensor/electronic suite, the Type 055 can take on an anti-ship, anti-submarine, anti-air, or land-attack role, making it the best candidate for a carrier escort. It's also capable of operating as a command flagship for any PLAN surface action group without a carrier.

The US Department of Defense has speculated that China wants to incorporate ballistic missile defense (BMD) systems on the Type 055, which could enable it to serve in a BMD/anti-satellite role similar to Japan's BMD destroyers.

Eight Type 055s are in service. At least three more are reportedly in varying stages of construction. China may build as many as 16 Type 055s in total.

Despite its young age, the class has already gained a reputation as one of the best surface combatants in the world.

"I'd say the Type 055 is the most capable in anti-surface warfare, but not as capable in the air defense and BMD role as a US [Arleigh] Burke DDG," Carlson, the retired US Navy captain, said. He said the Type 055's strike and ASW capabilities are about the same as its American counterpart.

Ticonderoga-class

The size, armament, and mission of the Type 055 are often compared to the US Navy's Ticonderoga-class cruiser. Measuring 567 feet long, displacing around 10,000 tons, and first entering service in 1983, the ships of the class are considerably older and smaller than the Type 055s.

But the Ticonderogas are no less potent and have a larger missile arsenal, with two sets of 61 Mk 41 VLS cells able to carry 122 missiles and two quad-tubed Mk-141 launchers at the stern.

Two Mark 45 5-inch guns are present at the stem and stern, as well as two Phalanx CIWS' and two triple-tubed Mark 32 torpedo tubes capable of firing Mk 46 or Mk 50 torpedoes. A helicopter hangar capable of housing two MH-60R Seahawk helicopters provides additional ASW capability.

The exact makeup of each Ticonderoga's missile arsenal is dependent on its mission, as it is capable of carrying a host of different missiles. These include Tomahawk cruise missiles for ground targets, Harpoon anti-ship missiles for hostile ships, and RUM-139 VL-ASROC anti-submarine missiles for enemy subs.

The missiles have ranges of up to 1,500 miles, 149 miles, and 10 miles respectively.

The Ticonderoga's main role, however, is air defense. It can carry a wide range of anti-air missiles, including Evolved Sea Sparrow SAMs, and all active variants of the Standard Missile family; the SM-2 Blocks III, IIIA, IIIB, and IV; the SM-3, and the SM-6.

Those missiles, which can intercept targets ranging from 35 miles to over 200, enable the Ticonderoga to provide an effective air defense umbrella against low- and high-altitude threats, including helicopters, drones, jets, and missiles.

In 2008, an SM-3 fired from the cruiser USS Lake Erie destroyed a defunct satellite at an altitude of some 150 miles, demonstrating its ability to perform anti-satellite missions.

Another defining asset of the Ticonderogas is the AN/SPY-1 passive phased array radar — a vital component of the AEGIS Combat System, an advanced and integrated naval defense system that combines command, detecting, tracking, and weapons control for comprehensive management of air, surface, and submarine threats, and which the Ticonderogas were the first ships to employ.

Twenty-seven Ticonderoga-class cruisers were built between 1980 and 1994, but only nine are in active service today.

Cruiser gap?

The importance of the Ticonderoga and the Type 055 to their respective fleets is hard to overstate. Their displacement, arsenal size, and ability to perform multiple missions and operate as flagships puts them at the top of the list of most important surface combatants — second, perhaps, only to the carriers.

In an acknowledgment of their capability, the US Department of Defense officially designates the Type 055 as a cruiser, despite China's own designation of destroyer, which is likely a PR move intended to make the PLAN seem less aggressive. (Destroyers typically have smaller displacements and arsenals than cruisers and play a less prominent role in the fleet.)

Consequently, their deployments are carefully monitored, with their standalone voyages seen as intentional shows of strength.

Type 055s have sailed in the waters off Alaska in 2021, 2022, and 2024, including as part of joint Chinese-Russian patrols. Recently, a Type 055 visited the island nation of Vanuatu, signaling to some that China was trying to increase its presence in the South Pacific.

The Ticonderogas have also been on the move. In 2022, the cruiser USS Port Royal sailed through the Taiwan Strait in a sign to China. More recently, in June, USS Normandy participated in a show of strength off Norway, and in September, USS Bunker Hill took part in a massive five-nation drill in the South China Sea.

Though both navies currently have nine cruisers in active service, this will not be the case for long. While China has only just entered the cruiser game, the US Navy has been seeking to decommission its cruisers for years.

The Navy argues that the cruisers have approached, passed, or will soon pass their expected service lives and that the cost of keeping the ships up and running is draining the service of funds and shipyard space.

In 2021, for instance, USS Vella Gulf lasted just one week into a deployment before leaks in a fuel tank required it to return to port. More mechanical problems were soon uncovered, and the ship spent two months undergoing repairs before it could rejoin its carrier strike group.

Navy Secretary Carlos Del Toro has even testified to Congress that some of the ships were unsafe. A modernization effort for seven cruisers, meanwhile, went as much as 200% over budget and fell years behind schedule.

The Navy wants to divest from ships it says it doesn't need and invest in new vessels that it argues can adequately fill in for the role of the Ticonderogas in the 21st century, like the new Flight III variant of the Arleigh Burke-class destroyers.

But Congress has so far rejected the Navy's plans to retire all of its remaining cruisers due to fears that they play too important a role in countering China, whose increasing might could be a means to try to seize the island of Taiwan by force.

Four Ticonderogas — Vicksburg, Cowpens, Leyte Gulf, and Antietam — were decommissioned in the last year. On November 4, Del Toro announced that the Navy would operate three cruisers planned to be decommissioned in 2026 into 2029, effectively extending their service lives. The rest are planned to be decommissioned before then.

China, meanwhile, will continue building Type 055s at rates virtually unthinkable to US shipyards.

• The US Navy is converting Zumwalt-class stealth destroyers into hypersonic missile shooters.
• The expensive Zumwalt class has struggled to find a suitable mission and weapons.
• The upgrade is part of the US' effort to keep pace with adversaries in fielding hypersonic weapons.

The US Navy's Zumwalt-class stealth destroyers are hailed as a revolution in naval warfare due to their next-generation design and advanced technology.

But nearly two decades after the first-in-class USS Zumwalt began construction, the world's most advanced surface combatants are still not ready for combat, victims of development problems, cost overruns, and ineffective systems.

Now, the sea service is retrofitting the Zumwalt-class destroyers to launch future hypersonic missiles in a bid to make the costly warships more useful by allowing them to strike targets from afar with greater precision.

The Zumwalt has been docked at a shipyard in Pascagoula, Mississippi, since August 2023 to integrate the new and untested weapon system.

The ship is expected to be undocked this week as it prepares for tests and a return to the fleet, according to a shipyard spokeswoman, though the Navy said it wants to begin testing the ship's new hypersonic weapon system in 2027 or 2028.

The world's largest, most advanced destroyer

The Zumwalt-class stealth destroyers are considered the most advanced surface warships in the world, equipped with innovative naval technology.

Named after Adm. Elmo R. Zumwalt Jr., the youngest chief of naval operations in US history, the lead ship USS Zumwalt is the largest destroyer in the world at 610 feet long. It can house a crew of nearly 200 sailors and accommodate one MH-60R Seahawk helicopter in its hangar.

General Dynamics Bath Iron Works and Huntington Ingalls Industries were behind the design and construction of the three stealth destroyers.

The warships feature an all-electric propulsion system and a composite deckhouse covered with radar-absorbing material to hide their sensors and communication systems. But the US Navy has struggled to arm them.

Due to the ship's manufacturing issues and soaring costs, the Navy reduced the Zumwalt class's overall size from 32 ships to just three: the Zumwalt, USS Michael Monsoor, and the future USS Lyndon B. Johnson, which is expected to commission after its combat systems are fully installed and activated.

The first shipborne hypersonic weapon

The stealth destroyers were armed with two 155 mm deck guns for shore bombardment, but ballooning manufacturing costs made the ammunition for the guns ridiculously expensive.

The Navy halted the ammo procurement in 2016, the same year the Zumwalt was commissioned, and publicly announced in 2018 that it was scrapping the now-useless main deck guns for a new weapon system.

In 2021, then-Chief of Naval Operations Adm. Mike Gilday said the stealth destroyers would be the first Navy warships to be armed with hypersonic missiles instead of its Block V Virginia-class submarines, saying that it would be an "important move" toward turning the surface ships into strike platforms.

The Navy said the first-in-class stealth destroyer's "upgrades will ensure Zumwalt remains one of the most technologically advanced and lethal ships in the US Navy."

Photos showed the Zumwalt's main deck gun mounts were removed. The cannons will be replaced with four all-up round canisters containing three hypersonic missiles each. These come in addition to its conventional missile arsenal of 80 vertical launch cells.

US efforts in hypersonic innovation

The US military is working on hypersonic weapons across all branches. The Zumwalts will be armed with the Conventional Prompt Strike (CPS) system, the Navy's joint hypersonic weapons program with the Army and US Strategic Command.

Described by STRATCOM as "a strong deterrence message to our adversaries," the "highly lethal platform" would launch like a ballistic missile but instead uses a two-stage solid-fueled rocket booster to get the projectile to travel at speeds faster than Mach 5 speed — nearly 4,000 mph. The booster allows the missile to change trajectory at these speeds, unlike a ballistic missile, and combined with its lower altitude flight complicates efforts to intercept it.

The weapon system features an all-up round (AUR) missile and a separate payload modular adapter, which the Navy is testing along with the missile and eject system.

"It's not like any other type of missile," Vice Adm. Johnny Wolfe, the Navy's director of strategic programs, told reporters at the Naval Submarine League's annual symposium last month. "You don't light this thing off inside."

The CPS system failed its first test in June 2022, as well as subsequent flight tests in March and September 2023. The first successful test was completed this summer.

"The testing that we need to do to get to the final integration of Zumwalt, that's irrespective of where the Zumwalt's at, whether it's in the water," Wolfe added.

In addition to the CPS system, the Navy is also developing a hypersonic air-launched anti-ship missile expected to be compatible with the F/A-18 Super Hornet fighter jet. However, few details about the $178.6 million program have been released to the public.

Scrapping the Zumwalts' twin turrets

Developed to provide off-shore precision fire support from a distance, the Zumwalt-class stealth destroyers were armed with a pair of Advanced Gun System (AGS) mounts to fire naval artillery from up to 100 nautical miles away — in what would've been the US Navy's longest-range shell in use.

However, after the Navy reduced the size of its Zumwalt fleet, manufacturing costs for the Long-Range Land-Attack Projectile-guided shells skyrocketed to about $800,000 to $1 million per round — about the same price as a cruise missile.

The rocket-assisted projectiles also fell short of the intended range, prompting the sea service to cancel production of the munitions, rendering the pair of high-velocity cannons useless.

Before announcing the new hypersonic weapon, the Navy floated other weapon systems to replace the failed gun mounts, including an electromagnetic railgun or futuristic laser weapons.

The hypersonic edge

In recent years, US adversaries like Russia and China have been developing hypersonic weapons, adding pressure on the Pentagon to prioritize its own hypersonic development efforts.

China has "the world's leading hypersonic arsenal," and Russia has already deployed two of its three hypersonic weapon systems in Ukraine, according to congressional testimony from Jeffrey McCormick, senior intelligence analyst at the National Air and Space Intelligence Center.

The US, however, has yet to field a single hypersonic weapon amid ongoing development and integration challenges across the military, including the Zumwalt-class artillery upgrade.

'Is it really worth the money?'

Research and development for the destroyer cost about $22.4 billion, and General Dynamics spent another $40 million just to construct a shipyard facility large enough to accommodate the giant hull segments.

Each ship cost an average of $7.5 billion — more expensive than the Navy's Nimitz-class aircraft carriers.

Even with all of their costly innovations, the Zumwalt-class vessels continued to be plagued by equipment problems and constantly needed repairs.

Last year, the Navy awarded Huntington Ingalls Industries with a $154.8 million contract to integrate the hypersonic weapon system aboard USS Zumwalt. The Congressional Budget Office also estimated that it would cost nearly $18 billion to buy and maintain 300 of the hypersonic boost-glide missiles for the next 20 years.

As the expenses of fielding US-developed hypersonic weapons pile up, some military analysts say the costs outweigh the benefits.

"This particular missile costs more than a dozen tanks," Loren Thompson, a defense analyst at the DC-based think tank Lexington Institute, told the Associated Press. "All it gets you is a precise non-nuclear explosion, someplace far, far away."

"Is it really worth the money?" Thompson continued. "The answer is, most of the time, the missile costs much more than any target you can destroy with it."

A steep price to pay to keep pace

While conventional missiles may cost less, long-range hypersonic weapons increase the chances of striking the targets of adversaries protected by advanced air defense systems like those of China and Russia.

"The adversary has them," retired Navy Rear Adm. Ray Spicer, CEO of the US Naval Institute, told the AP. "We never want to be outdone."

Bryan Clark, a defense analyst at the Hudson Institute, told the AP that while the US stealth destroyers were "a costly blunder," the Navy could "take victory from the jaws of defeat here and get some utility out of them by making them into a hypersonic platform."

The jury is still out on whether the Zumwalt hypersonic upgrades are worth the hefty price tag, but it would at the very least give the stealth destroyers a purpose.

"Zumwalt gave us an opportunity to get [hypersonics] out faster," Gilday told USNI News in 2022," and to be honest with you, I need a solid mission for Zumwalt."
