The Navy's USS Georgia, an Ohio-class guided-missile submarine capable of carrying up to 154 Tomahawk cruise missiles, has completed its last mission and will begin inactivation this week, leaving a firepower gap the fleet has no immediate plan to fill.
The 560-foot nuclear submarine transited the East River on Monday, July 27, and pulled into its homeport at Kings Bay, Georgia, closing out more than four decades of continuous service. The Navy confirmed the vessel will officially begin its scheduled inactivation process on July 31, 2026, just four days after docking for the last time.
Commissioned on February 11, 1984, the USS Georgia (SSGN 729) spent its early career as a ballistic missile submarine, an SSBN, in Navy shorthand, carrying nuclear-armed missiles as part of America's strategic deterrent. In 2008, the Navy completed a conversion that turned the Georgia into a guided-missile submarine, or SSGN, swapping its nuclear payload for conventional Tomahawk land-attack cruise missiles and the ability to support special operations forces. That conversion gave the boat a second life and a different mission: projecting conventional firepower anywhere the fleet needed it.
154 missiles per boat, and nothing in the pipeline to match it
The Georgia is one of four Ohio-class submarines converted to the SSGN role. Each can reportedly carry up to 154 Tomahawk cruise missiles, a staggering conventional punch packed into a single hull. The Ohio class as a whole numbers 18 boats: 14 remain configured as SSBNs for nuclear deterrence, while the four SSGNs handle conventional strike and special operations missions. Each SSGN carries a crew of roughly 155 sailors.
The retirement of the Georgia is not an isolated event. The Navy has acknowledged that the remaining three SSGNs, USS Ohio, USS Florida, and USS Michigan, are all scheduled for retirement over the next several fiscal years. When they go, the fleet loses more than 600 Tomahawk launch tubes that no current replacement can match.
The Virginia-class Block V submarine, the Navy's newest attack boat, includes a Virginia Payload Module designed to carry cruise missiles. But each Block V can hold up to 40 Tomahawks, roughly a quarter of what a single Ohio-class SSGN brings to the fight. Losing four SSGNs and replacing them with boats that carry a fraction of the firepower is not a one-for-one swap. It is a net reduction in conventional strike capacity at sea.
The Navy is also developing the Columbia-class ballistic missile submarine to replace the aging Ohio-class SSBNs that still carry the nuclear deterrent. But the Columbia program addresses the nuclear mission, not the conventional strike role the SSGNs filled. The SSGN capability gap remains an open question with no publicly announced solution.
A fleet stretched thin keeps shedding warships
The Georgia's retirement fits a broader pattern. The Navy has been retiring capital ships faster than replacements arrive, leaving gaps in carrier strike groups and submarine rotations that adversaries can count as easily as Pentagon planners can.
The service branch has faced a string of operational challenges in recent years. A fire aboard the USS Indianapolis at Naval Station Mayport injured seven sailors and underscored the strain on aging vessels and overstretched maintenance schedules.
Meanwhile, institutional problems extend beyond hardware. Leadership turnover across the military has accelerated, with top commanders forced out as the Pentagon reshapes its senior ranks. And the Navy itself has not been immune to scandal, a high-profile bribery case involving a Navy admiral raised hard questions about accountability inside the service.
The Georgia's departure also echoes across other branches. The Marine Corps is phasing out the F/A-18 Hornet by 2030, cutting maintenance jobs at three bases in the process. Across the armed forces, platforms that served for decades are heading for retirement while their successors lag behind schedule, run over budget, or carry less capability per unit.
42 years of service, and four days to start the clock on goodbye
The Navy's statement framed the moment in measured terms. "This marks the submarine's final return from operations before officially commencing her scheduled inactivation process on July 31 after 42 years of active service," the service said.
A second Navy statement cast the return in broader terms, calling it "the beginning of the end for one of the Navy's most versatile submarine classes." That attribution was general, no specific spokesperson was named, but the sentiment is hard to argue with. The Ohio-class SSGNs did things no other platform in the fleet could do: park 154 cruise missiles off a hostile coastline, deliver special operators, and do it all from a submarine that an adversary could not easily find or track.
What the Navy has not said publicly is what, exactly, replaces that capability once all four SSGNs are gone. The Virginia Payload Module adds capacity, but at 40 missiles per boat, the math does not work. The fleet would need nearly four Virginia Block V submarines to match the missile loadout of a single retiring SSGN, and the Navy is not building them at that rate.
The specifics of the Georgia's final deployment remain undisclosed. The Navy did not describe where the submarine operated, what missions it carried out, or whether any ceremony marked its last arrival at Kings Bay. The inactivation process itself, whether the boat will be scrapped, mothballed, or preserved, was not detailed in the Navy's public statements.
Retiring a warship after 42 years of faithful service is not the problem. Retiring it without a credible replacement, and pretending the math still adds up, is.
