WASHINGTON – The Navy has a new vision for what its enormous high-tech destroyers will do: Killing enemy warships at extended ranges.
The Navy is asking Congress to fund a conversion of its 600-foot stealth destroyers from primarily a land attack ship to an anti-surface, offensive strike platform, according to budget documents released Feb. 12.
The service’s 2019 budget request includes a request for $89.7 million to transform its Zumwalt-class destroyers by integrating Raytheon’s long-range SM-6 missile, which can dual hat as both an anti-air and anti-surface missile, as well as its Maritime Strike variant of the Tomahawk missile.
Converting DDG-1000 into a hunter-killer is a win for the surface warfare community’s years-long drive to beef up the force’s offensive capabilities. It also answers the bell for U.S. Pacific Command, which has been pushing for the Navy to add longer range weapons to offset the increasing threat from Chinese long-range missile technology.
The SM-6 is a versatile missile that the Navy has been excited about. In August, the Navy shot down a medium-range ballistic missile target with the SM-6, which uses a fragmenting explosion near its target as the kill mechanism. This is different from the SM-3 Block IIA in development that hits its target directly. It can also be used to hit surface targets at sea and on land from hundreds of miles away.
The Navy is planning to buy 625 of the SM-6 over the next five years.
For the Maritime Tomahawk, Raytheon is integrating a new seeker into its tried-and-true strike missile for long-range ship-on-ship engagements.
The decision to switch the requirements from a land-attack platform to an anti-surface platform came in November following a review of the requirements, according to the documents.
“After a comprehensive review of Zumwalt class requirements, Navy decided in November 2017 to refocus the primary mission of the Zumwalt Class Destroyers from Land Attack to Offensive Surface Strike,” the documents read. “The funding requested in [FY19] will facilitate this change in mission and add lethal, offensive fires against targets afloat and ashore.”
USNI News first reported in December that the Navy was eyeing converting the Zumwalt to a surface strike platform.
The lead ship in the class, Zumwalt, is currently getting an overhaul and combat systems installation in San Diego. The Michael Monsoor, the second in the class, completed acceptance trials this month.
Getting a surface strike platform in the Pacific fits snugly in with the distributed lethality concept that was championed by former Naval Surface Force Pacific commander Vice Adm. Thomas Rowden. Rowden argued that surface ships can and should be used in an offensive capacity, not just be relegated to the defense of the aircraft carrier.
By adding long-range systems to every kind of ship, Rowden argued, it forces potential adversaries to expend resources looking not just for destroyers and cruisers but also littoral combat ships and even amphibious ships that have not had a strike role in the past.
In testimony submitted Feb. 14 to the House Armed Services Committee, PACOM commander Adm. Harry Harris said China’s advancing capabilities made investing in long-range systems for his theater is a must. All three of the Zumwalt-class destroyers will be based in the Pacific.
“I need increased lethality, specifically ships and aircraft equipped with faster and more survivable weapons systems,” Harris wrote. “Longer range offensive weapons on every platform are an imperative.”
The money requested in 2019 also funds a combat systems refresh, a datalink upgrade and some new signals intelligence collection equipment. It also goes after some cyber-security hardening and replacing components of the ship’s computing systems that are becoming obsolete.
Funds will also be expended replacing displays for consoles that run the ship’s computing systems, known as the Common Display System . There are about 40 consoles that use the display per hull and 22 on the class’s shore trainer.
“The CDS variant on Zumwalt class are unique configuration based on a 10 year old design and should be aligned with ongoing modernization efforts in the Fleet.”
Guns down
One thing the budget isn’t funding is a new round for the ship’s purpose-built Advanced Gun System. In late 2016, the service canceled its Long Range Land Attack Projectile, which cost about a million dollars per round, and has struggled to come up with a replacement round for the gun.
“The Advanced Gun Systems will remain on the ships, but in an inactive status for future use, when a gun round that can affordably meet the desired capability is developed and fielded,” the documents read.
In January, Zumwalt’s former commanding officer, Capt. James Kirk, said the Navy was in a holding pattern on the guns. While the service is keeping an eye on a couple key technologies that could fill in the gap left by LRLAP, “there is not a plan right now for a specific materiel solution for the replacement round,” Kirk told reporters at the Surface Navy Association symposium.
“We continue to monitor industry’s development and technical maturation. An example of that is the Hyper Velocity Projectile,” he said, referring to a high speed guided munition made by BAE Systems and originally developed for use in electromagnetic rail guns.
“We’re monitoring that technical maturation to see do we get there to get the kind of ranges and capabilities we want, that’s the right bang for the buck, cost to capability, for the Navy. We’re monitoring that, but we have not made a decision for that yet.”
The Navy got in its present pickle with the 155mm/62-caliber gun with automated magazine and handling system because the service cut the buy from 28 ships, to seven, and finally to three.
The AGS, the largest U.S. naval gun system since World War II, was developed specifically for the Zumwalt class, as was the LRLAP round it was intended to shoot. There was no backup plan so when the buy went from 28 to thee, the costs stayed static, driving the price of the rounds through the roof.
“We were going to buy thousands of these rounds,” said a Navy official familiar with the program told Defense News at the time. “But quantities of ships killed the affordable round.”
