The size of an Ohio-class submarine is almost unbelievable when one first stands on a naval pier and watches it slowly glide away from the dock. The massive black steel hull extends far beyond what one might anticipate from something meant to vanish beneath the sea. While setting up lines and inspecting equipment, crew members move silently along the deck. Then, with hardly a ripple in its wake, the submarine just plunges into open water.
These ships have been quietly transporting some of the most concentrated firepower ever put on a single naval platform for decades. However, the U.S. Navy is currently getting ready to retire a number of them. Furthermore, the repercussions might be more severe than the public discourse indicates.

Originally constructed as ballistic missile submarines during the Cold War, the Ohio-class guided-missile submarines include the USS Ohio, USS Michigan, USS Florida, and USS Georgia. They were transformed into cruise-missile platforms in the early 2000s that could fire massive Tomahawk missile salvos, with each vessel holding up to 154 missiles. That figure is more significant than it seems.
Analysts discuss “magazine depth”—the quantity of weapons on hand before a ship needs to resupply—in naval planning rooms. The Ohio-class submarines were nearly unbelievably powerful in that silent math of war. More cruise missiles could be delivered by a single ship than by several whole surface fleets put together.
It is evident why commanders placed such a high value on them when one watches military drills or reads after-action reports. They could remain undetectable underwater and attack targets thousands of miles away. No need for escorts. You don’t need an air cover. Just a submarine, waiting, drifting in silence. However, every machine eventually ages.
Even nuclear submarines have operational limitations, and the majority of Ohio-class vessels went into service in the 1980s. Reactors get older. Upkeep becomes more challenging. Hulls get tired. Even the strongest ships eventually have to retire.
According to the Navy’s current plan, the remaining Ohio guided-missile submarines will be decommissioned between 2026 and 2028. This appears to be standard modernization on paper. Older ships are retired from service. They are replaced by new ones. Perhaps reality is more intricate.
Recently, defense planners looked at the data and found something concerning: 616 Tomahawk launch tubes would be removed almost instantly if these submarines were retired. Over 2,000 missile launch cells could be eliminated from the fleet when older surface ships with vertical launch systems are retired. A drop like that is not insignificant.
Most people outside of defense circles might hardly notice the difference. Because of their inherent secrecy, submarines hardly ever make headlines. However, that diminished firepower modifies deterrence, deployment, and crisis response calculations within strategic planning models. Another practical question is: what will take their place?
Although the Navy is developing Columbia-class submarines, their main purpose is nuclear deterrence. Ballistic missiles, not Tomahawk cruise strikes, are the main focus of their mission. Put differently, they have a completely different strategic function.
The Virginia-class attack submarines, especially the more recent models with the Virginia Payload Module, are an additional choice. The capacity of these submarines is increased to about 40 Tomahawks per boat by carrying extra missile tubes. It’s difficult to ignore the math, though. It’s impressive to have forty missiles. It’s not 154, though.
Even non-experts can see the difference when they stand on a shipyard observation platform and gaze at a Virginia-class submarine that is being built. The more recent boats have more contemporary sensors, are sleeker, and are easier to maneuver. They are wonders of technology. However, they just don’t have as many weapons.
This presents an unsettling possibility. The U.S. Navy may encounter what strategists sometimes refer to as a capability gap in the late 2020s and early 2030s—a time when older platforms retire before replacements are delivered.
Although the tone is generally cautious, defense officials acknowledge the risk. The Navy contends that more recent submarines offer better targeting capabilities, enhanced stealth, and increased survivability. Some of the raw missile numbers may be offset by those attributes.
Maybe they will. However, military strategy is stubbornly shaped by numbers. Having hundreds of extra missiles on hand can alter how adversaries assess risk in large-scale conflicts or deterrence situations.
The Ohio submarines’ special operations capability is another aspect that gets less attention. These vessels were outfitted with capabilities that enabled them to support covert operations and deploy Navy SEAL teams when they were converted into guided-missile submarines.
As a result, they could function as underwater command centers, using a single platform to launch missiles, obtain intelligence, and deploy special forces. Not many ships provide that combination.
It’s difficult to ignore how subtly these submarines have influenced contemporary naval operations. They launched precise attacks without ever showing up on the horizon during conflicts ranging from the Gulf War to strikes in the Middle East. The work was virtually anonymous to the crews involved.
It seems like the Navy is striking a careful balance between risk and modernization as this shift takes place. On the one hand, it would be costly and impractical to maintain aging submarines indefinitely. However, removing them too soon could result in a short-term firepower shortfall.
History indicates that during technological shifts, the military frequently encounters these situations. Similar uncertainties accompanied the mid-20th-century transition from battleships to aircraft carriers.
The speed at which new technologies emerge may determine whether the retirement of the Ohio-class submarines becomes a strategic issue or merely a footnote.
However, the image of massive submarines that used to carry hundreds of missiles each, gradually nearing the end of their service lives, is still striking for the time being.
And one of them is probably still on patrol somewhere in the Pacific or Atlantic, moving stealthily through murky waters while carrying out a mission that most people will never learn about.
