Unique US Navy submarine returns to base after two-year ...
The SSGN sub-variant of the Ohio class are due begin leaving service from 2026, with the four-boat batch decommissioned entirely by 2028.
www.naval-technology.comHere’s the latest overview on Ohio-class submarines based on recent reporting.
-
The USS Ohio (SSGN-726), the lead ship of the Ohio-class converted to a guided-missile submarine, completed a major maintenance period in early 2025 and returned to operations in the Indo-Pacific region. This marks a continued emphasis on the Ohio-class’ Tomahawk-capable, long-endurance role while the Navy pivots to newer Columbia-class assets in the longer term.[2]
-
Reports in 2024–2025 indicated ongoing assessments of the Ohio-class fleet as the service plans retire four of the class in the late 2020s and replace them with Columbia-class SSBNs and Virginia-class variants with expanded payloads (VPM) to preserve strike capability. Some outlets noted that the four SSGNs (Ohio, Michigan, Florida, Georgia) would be phased out as part of this transition, though the exact retirement dates can vary by program updates.[2]

Context from broader coverage: Ohio-class boats have served as the backbone of U.S. sea-based strike capability, with 154 Tomahawk missiles on SSGN-configured boats, and 24 Trident missiles on SSBN-configured boats in earlier configurations. The class remains in service during the transition to newer platforms, underscoring its continued relevance for conventional strike and special operations support.[1][2]
Illustration (example): If you’d like a quick visual, I can generate a simple chart showing the evolution from SSBN to SSGN within the Ohio-class, and the planned transition to Columbia-class and Virginia-class with VPM.
