The U.S. Navy’s USS Georgia, an Ohio-class guided-missile submarine, has begun the retirement process after 42 years of active service. After returning to its home port at Naval Submarine Base Kings Bay in Georgia on July 27, 2026, the submarine is emerging as a symbol of the Navy’s transition to a new generation of strategic assets.
The Role and Significance of Ohio-Class Submarines
A total of 18 Ohio-class submarines were built between 1981 and 1997. Fourteen entered service as ballistic-missile submarines, or SSBNs, while four were operated as guided-missile submarines, or SSGNs. USS Georgia was commissioned as a ballistic-missile submarine on February 11, 1984, before being converted into a guided-missile submarine in the early 2000s and returning to service in March 2008.
The Ohio-class submarines converted to guided-missile platforms pack an enormous striking capability. The four SSGNs, including USS Georgia, can each carry up to 154 Tomahawk cruise missiles, giving the four-boat fleet a combined capacity of 616 missiles.
Retirement Timeline and Strategic Gap
USS Georgia began the formal deactivation process on July 31, 2026. It is scheduled to move to Norfolk in July 2027 to undergo final decommissioning at Norfolk Naval Shipyard. Following its retirement, USS Ohio, USS Florida and USS Michigan are expected to leave service in fiscal years 2027, 2028 and 2029, respectively.
The Navy is currently moving ahead with plans to retire all of its Ohio-class guided-missile submarines within the next three years. The move is expected to create a significant gap in the service’s undersea strike capacity. Concerns are particularly acute over the lack of sufficient alternatives for operating Tomahawk cruise missiles.
Plans for the Next Generation of Submarines
To address the aging Ohio-class ballistic-missile submarines, the U.S. Navy is developing the Columbia-class submarine. The Navy plans to operate 12 Columbia-class boats, compared with the 14 Ohio-class SSBNs, and each vessel will carry 16 Trident D5 ballistic missiles instead of 24.
The Columbia-class program has been designated the U.S. Defense Department’s highest-priority acquisition program, with total costs projected to exceed $130 billion. The first boat, USS District of Columbia (SSBN-826), is scheduled for delivery in October 2027 and is expected to enter service by 2031. However, limited industrial capacity and technical challenges have raised concerns that the schedule could slip.
Meanwhile, the Navy is also planning to deploy Virginia-class Block V attack submarines to partially replace the Ohio-class guided-missile submarines. Equipped with the Virginia Payload Module (VPM), these boats can carry up to 40 Tomahawk missiles each—far fewer than the 154 carried by an Ohio-class SSGN.
Frequently Asked Questions (FAQ)
Q. What role did USS Georgia perform?
A. USS Georgia was commissioned as a ballistic-missile submarine in 1984, but was converted in the mid-2000s to a guided-missile submarine capable of carrying up to 154 Tomahawk cruise missiles. It also carried out a range of strategic missions, including transporting special operations forces.
Q. How will the retirement of the Ohio-class submarines affect U.S. defense capabilities?
A. The retirement of all Ohio-class guided-missile submarines is expected to create a significant gap in cruise-missile strike capacity. Addressing that gap before the Columbia-class submarines begin entering service in earnest after 2031 will be a major challenge for the Navy.
Q. How much more capable are Columbia-class submarines than Ohio-class boats?
A. The Columbia class incorporates several advanced technologies, including a reactor designed to eliminate the need for midlife refueling, an electric-drive propulsion system for quieter operations, and a missile compartment co-designed with the U.K. Royal Navy for its Dreadnought class. However, the number of missiles carried will fall from 24 to 16.
Q. When will all Ohio-class submarines be retired?
A. USS Georgia is scheduled to begin the process in 2027, followed by USS Ohio in fiscal year 2027, USS Florida in fiscal year 2028 and USS Michigan in fiscal year 2029.
Q. Can Virginia-class Block V submarines fully replace Ohio-class SSGNs?
A. Virginia-class Block V submarines can carry up to 40 Tomahawk missiles, helping to offset the loss of capability, but that is far below the 154-missile capacity of an Ohio-class SSGN. They are therefore viewed as a supplement rather than a complete replacement.
Q. What was USS Georgia’s final operational mission?
A. The Navy assessed that USS Georgia likely took part in Operation Midnight Hammer in 2025, conducting Tomahawk missile strikes against Iran’s nuclear facilities at Isfahan.
