Sgt. Cole Hoppert perched behind a V-22 Osprey earlier this month, zipping by way of the air someplace off the East Coast as he dumped little parachutes from cream-colored tubes out of the plane’s rear ramp and into the water under.
A weapons and ways teacher with Marine Medium Tiltrotor Squadron 162 out of North Carolina, Hoppert had by no means earlier than employed the almost 40-pound “sonobuoys,” expendable sensors designed to detect underwater sounds emitted from enemy submarines.
His unit’s participation within the naval integration train this month — dubbed Atlantic Alliance 2025 — signaled a notable development within the Marine Corps‘ involvement in anti-submarine warfare, or ASW, a greater than century-old idea the service is embracing alongside the Navy for contemporary battle.

“ASW shouldn’t be a normal mission and even speaking level,” Maj. Sean Penczak, the chief officer for VMM-162, with almost 13 years of expertise on the Osprey, stated in an interview with Navy.com on Friday. “That is the primary time I’ve actually heard about it, mentioned it and accomplished it.”
Almost 5 years in the past, then-commandant of the Marine Corps Gen. David Berger wrote that Marines would begin serving to the Navy battle submarines. He stated that Chinese language and Russian submarine capabilities continued to develop, and the Arctic and Pacific theaters have been changing into more and more necessary to combating them.
“The undersea battle might be so important within the Excessive North and within the western Pacific that the Marine Corps have to be a part of it,” he wrote in 2020. “Anti-submarine warfare is not only submarine versus submarine — it’s a fleetwide effort.”
Through the World Battle on Terrorism, the Marine Corps had largely shifted its focus away from these areas, particularly the Arctic, however to Berger, it grew to become evident that an amphibious power having spent 20 years focused on the Center East wanted to develop nearer to its Navy counterpart, even throughout missions beneath the ocean’s floor.
Years after Berger’s cost, that effort is rising, and whereas different Marine squadrons have participated in ASW missions as way back as 2022, officers informed Navy.com that the newest train marked a pivotal second for the Corps’ partnership with the Navy combating towards submarines.
“I might say we have reached an inflection level. We’re not simply exploring whether or not the Marine Corps can contribute to the undersea battle. We’re operationalizing how they contribute and folding that into theater-level ways,” Navy Capt. Invoice Howey, the director of maritime operations for Submarine Group Two, a unit out of Virginia that participated within the train, informed Navy.com in an emailed assertion.
“The MV-22 is not right here to exchange conventional platforms; it brings a singular functionality that enhances the battle,” he added, noting that the method will proceed to evolve and be refined. “With its pace, vary and payload capability, it is well-suited for distributing sensors and increasing undersea consciousness, particularly when different property are dedicated or working farther ahead.”
ASW is not a part of the Osprey’s major mission set and Marines do not traditionally prepare for it, officers stated. And whereas the plane is among the Corps’ key modes to shortly deploy Marines on beachheads, that does not imply it could possibly’t assist kill subs.
“It is similar to a number of the different missions that the V-22 already helps,” Hoppert stated. “The closest one can be battlefield illumination, which is the place we might throw a battlefield illum flare out the again — it is similar to that.”
Mark Cancian, a retired Marine colonel and senior adviser with the Heart for Strategic and Worldwide Research assume tank, stated that ASW is “fairly excessive” on the listing of necessary features for the navy, and likewise famous that the Atlantic theater, the place this train happened, is properly geared up to thwart “arguably essentially the most harmful a part of the Russian Navy” — submarines — given the U.S.-allied presence there.
“Russia can be onerous pressed to get a variety of submarines out into the Atlantic,” he stated. “Within the Pacific, it is trickier, as a result of the Chinese language have a variety of submarines, sometimes not as subtle, however they’re nearer to their residence bases, and their capability to problem the US in all domains is way better.”
Cancian stated that, within the grand scheme of the Marine Corps’ repertoire, “it is nonetheless an adjunct operate for Marine aviation, helpful doubtlessly, however an adjunct operate. You’ll be able to inform that the Marine Corps might be actually critical when it begins modifying plane for this mission, and I have never seen any indication of that but.”
Penczak stated that the planning for the train started months prematurely and included collaboration with the Workplace of Naval Analysis, which research developments in naval warfare. He stated that there was frequent communication with ONR to present and obtain suggestions concerning the new mission.
Preparation included lessons, understanding what the Navy wanted for that kind of mission, and figuring out how Marines and their plane would manage in assist of ASW. A number of Ospreys deployed for the mission with their respective pilots, a communications Marine and two to 3 crew chiefs like Hoppert managing the deployment of the sonobuoys over a number of days of coaching.
“On the finish of the day, the ASW evolution was an distinctive alternative,” Penczak stated. “It executed exceptionally properly, and I would not foresee any points for an additional VMM being tasked to go assist one in every of these vignettes, to have any points going out to execute.”
Whereas carrying the tubes was “fairly bodily demanding,” it wasn’t something the crew chiefs could not deal with, Hoppert stated, they usually have been “capable of unfold the workload fairly evenly” as they rotated tasks between ASW work and their regular plane tasks.
“It is the identical rules behind it,” he added, alluding to different Osprey missions when requested how he would advise one other crew chief embarking on the ASW mission for the primary time. “So do not overthink it. It is fairly related.”
