Here’s the latest I can share based on recent reporting:
- The US Navy has deactivated the Los Angeles-class submarine USS Boise (SSN 764) after extended sustainment delays, part of a shift in focus and budget toward newer classes like Virginia and Columbia. This marks a notable change in the fleet’s Los Angeles-class viability and indicates that some boats may be retired or moved off-active service as maintenance backlogs are resolved.[1][3]
- Separately, USS Cheyenne (SSN 773) completed the first Los Angeles-class refueling overhaul under the Service Life Extension Program (SLEP), extending its core life and upgrading systems, signaling ongoing modernization efforts for remaining Los Angeles boats that are still slated for overhaul. Navy officials have considered additional Los Angeles submarines for SLEP in the FY2026 timeframe, subject to budget, which would influence the size and capability mix of the undersea force into the 2030s.[2]
Context and caveats:
- News about Los Angeles-class submarines often focuses on lifecycle decisions (deactivations, SLEP refits) and broader fleet modernization plans, rather than continuous, uniform deployments across all boats.[1][2]
- If you want, I can monitor for official Navy announcements or provide a concise timeline of Los Angeles-class boats that have undergone or are slated for SLEP, deactivation, or other major milestones, with direct citations after each item.
Would you like me to compile a brief, sourced timeline of the Los Angeles-class boats currently active, undergoing SLEP, or retired, with the latest confirmed dates?[3][2][1]
