US Navy Deactivates Los Angeles Submarine After 10- ...
The US Navy has announced the deactivation of the Los Angeles-class submarine USS Boise after more than 10 years of sustainment delays.
thedefensepost.comI don’t have live access to current news in this moment. Based on the latest widely reported items I’m aware of, here are the recent developments around the Los Angeles-class fast-attack submarines up to early 2026:
-
Service life extensions and SLEP activity: The U.S. Navy and its shipyards have been pursuing Service Life Extension Program (SLEP) refueling overhaul efforts for certain Los Angeles-class boats to restore reactor cores and modernize systems, with USS Cheyenne (SSN 773) highlighted as a notable example of a Los Angeles-class submarine undergoing SLEP work and returning to service readiness. This indicates ongoing emphasis on sustaining the class’s combat capability while planning for replacement by newer Virginia-class and Columbia-class platforms.[1]
-
Deactivations and fleet reshaping: In 2026 there were reports of deactivations within the Los Angeles class as part of a fleet-wide re-prioritization and budget realignment, with USS Boise (SSN 764) cited as an example of an older hull transitioning out of active service after extended sustainment delays. The Navy described the move as data-driven to shift resources toward higher-priority programs, including continued construction and upgrade work on newer classes.[2][3]
-
Combat and capability context: Media coverage in early 2026 highlighted the Los Angeles class as historically the largest production run of nuclear-powered attack submarines, noting both their extent of deployment and the challenge of replacing such a large legacy fleet with newer designs. While these outlets emphasize changing fleet composition, they also acknowledge the class’s enduring role in undersea warfare during the transition period.[5][7]
-
Public information and official pages: Official or semi-official outlets that track Los Angeles-class activity continue to document hull-level status, upgrade programs, and decommissioning decisions, reflecting ongoing modernization and workforce reallocation in support of Virginia-class and Columbia-class programs.[9][10]
If you’d like, I can:
- Narrow to a specific submarine’s status (e.g., USS Boise, USS Cheyenne) and summarize its current disposition and future plans.
- Pull the latest verified statements from U.S. Navy press releases or defense-focused outlets and present a concise, date-stamped timeline.
- Create a brief pros/cons comparison of continuing Los Angeles-class support versus accelerating replacement by newer classes, with a simple chart.
