A ‘persistent, proximate threat’: Why the Navy is preparing for a fight under the sea

As Russia and China bolster their own submarine fleets and capabilities, the U.S. Navy has renewed its focus on undersea threats and has labeled anti-submarine warfare a priority for all sailors — and perhaps some Marines, too.

In August, Russian President Vladimir Putin announced plans to acquire two nuclear submarines equipped with intercontinental ballistic missiles, and two diesel-powered submarines. And China, which owns four ballistic missile submarines, boasts a force of 50 diesel-electric attack submarines, the Nuclear Threat Initiative reported in February.

To counter these threats, the Navy reactivated its 2nd Fleet in 2018 to focus on threats from Russia — including those under the ocean — and more recently it has held exercises to improve its ability to fight enemy submarines.

“This is where the fight is … where the competition is,” retired Vice Adm. Andrew Lewis, then the commander of U.S. 2nd Fleet, told reporters in September 2020.

“Anti-submarine warfare is a primary mission for everybody in the United States Navy, regardless of what you wear on your chest,” Lewis said.

In recent years, Navy leaders have cautioned about increased Russian undersea activity in the Atlantic Ocean, and have warned that the continental United States is no longer a sanctuarysafe from such threats.

“Over the past several years, we’ve realized that there is a persistent proximate threat in the western Atlantic, primarily from Russian Federation Navy Forces, that has drawn a lot more attention due to the challenges that poses to our homeland defense,” Rear Adm. Brian Davies, commanding officer of Submarine Group 2 and deputy commander of the 2nd Fleet, told Navy Times.

“Specifically, Russian submarines now have advanced cruise missiles that have the range and accuracy to strike military and civilian targets throughout the U.S. and Canada and as a result, we put a lot more focus in the area of theater undersea warfare,” Davies said.

Although the Russian submarine fleet is dramatically smaller than it was at the height of the Cold War, it still has 11 ballistic missile submarines and 17 nuclear-powered attack submarines, according to the Nuclear Threat Initiative. These ballistic missile submarines are capable and technologically on par — at least in some ways — with the U.S. submarine fleet, said Bryan Clark, a retired submarine officer and a senior fellow at the Hudson Institute.

“You’ve got this numbers challenge from the China side, the capability challenge from the Russian side, which in some ways demands different approaches to anti-submarine warfare, but it creates for both cases a big problem,” Clark said.

Bryan McGrath, a former destroyer captain who runs the FerryBridge Group, a defense consulting firm, noted that while the Chinese fleet is not as technologically advanced nor as capable as the Russian fleet, they do have a “ridiculously capable shipbuilding base” that’s churning out submarines.

The undersea threat has become critical now, given the investment Russia and China have made into expanding their submarine forces, McGrath said.

“Bottom line for why now is that both of our major competitors are putting money, resources and technology into this domain,” McGrath said.

Why the Navy re-established the 2nd Fleet

When the U.S. 2nd Fleet was dissolved in 2011 amid the war on terror, undersea warfare was put on the backburner. But the command was resurrected in 2018in response to greater levels of Russian activity in the North Atlantic and Arctic, including undersea.

For the same reason, NATO’s Joint Force Command Norfolk was stood up and the command reached full operational capability in July 2021. According to Lewis, who was also the commanding officer of JFC Norfolk, the command “creates a link between North America and Europe and helps to further develop the desired 360-degree approach for our collective defense and security.”

It is the only operational NATO command on the North American continent, and has air, surface and subsurface capabilities.

The Navy also revived Submarine Group 2 in September 2019 to streamline the Navy’s ability to command and control undersea warfare assets in the Western Atlantic.

Similar to combatant commands, the Navy has theater undersea warfare commanders in Naples, Italy, working with the 6th Fleet, and a theater undersea warfare commander in Yokosuka, Japan, working with 5th Fleet and 7th Fleet. Still another in Pearl Harbor works primarily with the 3rd Fleet. But that same structure was absent for 2nd and 4th Fleet, Davies said.

“We really didn’t have a theater undersea warfare commander that was dedicated to a fleet on this side of the Atlantic serving, basically, NORTHCOM and U.S. Fleet Forces Command, and that made it a natural fill in,” Davies said, referring to SUBGRU2.

The command will soon celebrate its second anniversary, and recently became the organization responsible for training and certifying the other theater undersea warfare commanders to ensure they are fully trained, have all the necessary equipment they need and have the appropriate personnel.

“The command, although not in final operating capability yet, is getting closer every day as we get to train and exercise like we would one day fight,” Davies said.

The Navy had the opportunity to do just that while honing its undersea warfare skills in a new exercise called Black Widow — which just wrapped up its second iteration in August. The exercise aimed to explore new tactics, techniques and procedures, and refine existing ones, Davies said.

Specifically, the exercise relied on a mixture of scripted scenarios, coupled with cutting edge technologies and existing force structure technology that will be used for the next decade, Davies said.

While many of the concepts tested were classified, Davies said “our tactics, techniques and procedures really centered on finding an undersea threat that was very adept at using the environment and the topography to their advantage.”

The Undersea Warfighting Development Center in Groton, Connecticut, is responsible for establishing the exercise’s objectives, and will then use the data collected from Black Widow to provide an assessment of the exercise.

Those results will then be shared with the Naval Aviation Warfighting Development Center and the Naval Surface and Mine Warfighting Development Center, he said.

“One of the things that the Navy can continue to work on is looking for every available opportunity to train together as this system of systems or team of teams, however you want to refer to it,” Davies said.

“When we have available bandwidth, we ought to be continuing to scratch and claw for every opportunity to get out there and work together in advancing this art of undersea warfare,” Davies said.

Will the Marine Corps get involved in anti-submarine warfare?

Although the U.S. Navy has historically been the service primarily responsible for anti-submarine warfare, that could change since the Marine Corps wants to become involved.

Commandant Gen. David Berger said in November it’s imperative for the Marine Corps to step in and suggested the service could provide logistics support and air defense as ways to counter the undersea threat.

“The undersea fight will be so critical in the High North and in the western Pacific that the Marine Corps must be part of it,” Berger wrote in a U.S. Naval Institute article from November 2020.

Specifically, Berger proposed that the Marine Corps deploy to bases in the Atlantic’s North Sea or the South China Sea to restrict the movement of Russian or Chinese submarines in the event of undersea war.

“By offering forward logistics and support, as well as sensor and strike capabilities, Marine expeditionary advanced bases (EABs) could make a significant contribution to undersea warfare campaigns, including holding Chinese and Russian submarines at risk,” Berger said.

These EABs could also house Navy P-8A Poseidons and MH-60R Seahawks, and the Marine Corps could offer air-defense and logistical support for these aircraft, Berger said.

Another role the Marine Corps could assume is operating unmanned aerial vehicles outfitted with anti-submarine warfare sensors and sonobuoys, and then “deploy and operate passive and active acoustic arrays in adjacent littoral waters,” Berger said.

“In the event of hostilities, when cued by these organic sensors or other joint ISR capabilities, EABs could harass and potentially neutralize Russian submarines with ground-launched ASW missiles or light torpedoes from Marine aircraft,” Berger said.

McGrath agreed there’s benefit in having Marine EABs equipped with a series of launchers with land-attack weapons, along with weapons that could sink ships and take down ballistic missiles, as part of a larger architecture within the joint force.

But McGrath has reservations about the Marine Corps becoming too involved in undersea warfare, given the cost of purchasing anti-submarine warfare platforms like P-8 Poseidons and Virginia-class submarines.

“Anti-submarine warfare is a science and an art and it’s difficult, and it is a mission that pretty much only the United States Navy does within the Joint Force,” McGrath said.

“There’s a lot of money that goes into that, and I want the Marine Corps busy doing Marine Corps things,” McGrath said. “And I don’t think finding submarines is among them.”

Clark believes the Navy first must get down to business incorporating unmanned systems before the Marine Corps jumps in to tackle anti-submarine warfare.

“The Navy’s going to have to first work through the use of unmanned systems to a greater degree, because the Marines aren’t going to be doing anti-submarine warfare unless they’re able to tap into what unmanned systems are going to be doing for the sensing,” Clark said.

The role of unmanned vehicles

Experts believe one solution to modernize anti-submarine warfare is to use autonomous systems to track, trail and potentially engage enemy submarines to neutralize the threat, which would then free up other resources like destroyers for other tasks and cut down on operating costs.

“The unmanned systems give you this ability to do persistent anti-submarine warfare, at a lower cost in peacetime than your manned systems,” Clark said.

According to a report from the Hudson Institute issued in September 2020, the U.S. Navy’s anti-submarine warfare approach likely can’t contend with undersea threats in the event of a conflict or crisis.

The report detailed how the Navy currently relies on a complex web for anti-submarine warfare involving seabed sensors, maritime patrol aircraft, destroyers and ultimately, submarines. But that approach could become challenging in the event these manned platforms are required elsewhere — such as in a time of crisis, the report said.

This strategy could also run into problems if enemy submarines were to overwhelm an area. In addition, the cost of operating systems such as a destroyer and a P-8 Poseidon aircraft could become too expensive if there’s a persistent need during periods of flat or declining budgets, the report says.

For example, Clark said it is cheaper to purchase a medium unmanned surface vessel than a destroyer, and then use the unmanned vessel either infrequently or not at all. However, in the event of a conflict, that medium unmanned surface vessel could be deployed while destroyers are conducting other engagements not related to anti-submarine warfare, he said.

“ASW is really a lot of searching around and following and chasing submarines,” Clark said. “It’s not like air defense where it happens very quickly, and so it’s more like just a long-term surveillance mission. So, in peacetime, it is a lot of just waiting around for a submarine to come by, detecting the submarine, and then following the submarine.”

The report called for using unmanned systems, including medium unmanned surface vessels and medium-altitude long endurance unmanned aerial vehicles like the MQ-9B SeaGuardian, but noted that not all of the systems it cited are employed operationally yet. As a result, the report suggests that this unmanned approach could occur over the next five to 10 years to allow such systems to mature.

The Navy has focused on developing drones that could participate in anti-submarine warfare, and has started to test out unmanned systems that could be used in tracking submarines.

In November 2020, during the development process for the MQ-9B SeaGuardian drone, the Navy and General Atomics deployed 10 sonobuoys from an MQ-9A Block V Reaper and tracked a simulated submarine target.

Never before had an aerial drone dropped a self-contained anti-submarine warfare system. The testing “paves the way” for additional development of more anti-submarine warfare capabilities from MQ-9s, according to General Atomics.

What’s next for the Navy?

Safe havens don’t exist anymore, and that means the Navy must be poised to carry out combat near its home turf, according to Vice Adm. Daryl Caudle, the head of Submarine Force Atlantic.

“Russia took a knee for over a decade and allowed a lot of folks to think the homeland is a sanctuary from Russian forces,” Caudle told reporters in September 2020. “Our homeland is no longer a sanctuary. We have to be prepared to conduct high-end combat operations in local waters.”

If faced with a crisis or outright hostilities, Clark envisions Russia capitalizing on its submarine force, including threatening the continental United States or heading toward Naval Submarine Base Kings Bay in Georgia to harass U.S. ballistic missile submarines trying to get in or out of port.

Meanwhile, the Chinese’s large submarine fleet would likely try to “flood the zone” to overwhelm U.S. undersea warfare assets, threaten U.S. Naval forces with attack, or try to blockade Guam or Taiwan, he said.

“For the U.S., going against the Chinese, the goal is just keep them away from ships,” Clark said. “It doesn’t matter if they continue to operate or not, as long as they stay away from the ships.”

“Whereas with the Russians, there may be a need to actually sink those submarines because they will — once they get towards the East Coast — they’re going to be a constant threat,” Clark said.

McGrath is worried that the type of equipment to deal with these potential threats won’t receive adequate support in future budgets. The Navy’s proposed budget for fiscal 2022 includes a request for two Virginia-class attack submarines with a topline budget of $211.7 billion — an overall increase of $3.8 billion from what was enacted in FY2021.

Chief of Naval Operations Adm. Michael Gilday has emphasized that the service can afford a fleet of approximately 300 ships, but has said that the request aligns with the U.S. Navy’s future fleet design plans.

“My fear is that the expense associated with building the Navy that seriously contends with these threats will not receive the attention it deserves, in and among all of the other priorities that our nation seems to have,” McGrath said.

For the future, McGrath suggested the U.S. build unmanned acoustic sensors, both for undersea and surface vessels, and for the Navy to acquire more P-8 Poseidon aircraft and attack submarines. That’s what “we do better than anyone else in the world is attack submarines,” he said.

“That advantage is something that I think we need to never forget, we need to continue to invest in, and we need to double down on.”
