Fact check: What are the names of the US Navy submarines that have been lost in recent years?

1. Summary of the results

Based on the analyses provided, no US Navy submarines have been definitively lost in recent years. The sources consistently show that while several US Navy submarines have experienced significant accidents and collisions, they were damaged rather than lost entirely.

The most frequently mentioned incidents include:

• USS Connecticut - A Seawolf-class submarine that collided with an underwater seamount in 2021 and is scheduled to return to service in 2026 ^{[1] [2] [3]}
• USS San Francisco - A Los Angeles-class submarine that collided with an underwater seamount in 2005, resulting in one death and 97 injuries, but was not lost ^[4]
• USS Hartford and USS Jacksonville - Mentioned in submarine incident lists but without confirmation of being lost ^[5]

2. Missing context/alternative viewpoints

The original question assumes that US Navy submarines have been lost in recent years, but the analyses reveal this premise may be incorrect. Important missing context includes:

• International submarine losses are well-documented, including the Russian submarine Kursk, Chinese submarine Changcheng 361, Indonesian submarine KRI Nanggala-402, Argentinian submarine ARA San Juan, and Russian submarine Nerpa ^[6]
• The distinction between "damaged" and "lost" is crucial - submarines like the USS Connecticut suffered severe damage requiring years of repairs but were not considered total losses ^{[1] [2]}
• Historical context shows that while submarine accidents occur, modern US Navy submarines are rarely completely lost due to advanced safety systems and rescue capabilities

3. Potential misinformation/bias in the original statement

The original question contains a false premise by assuming that US Navy submarines have been lost in recent years. This assumption could stem from:

• Conflating damage with total loss - high-profile accidents like the USS Connecticut collision may create the impression of submarines being "lost" when they are actually being repaired
• Confusion with international incidents - the well-publicized losses of foreign submarines ^[6] may be mistakenly attributed to the US Navy
• Incomplete reporting that focuses on dramatic accidents without clarifying the ultimate fate of the vessels involved

The analyses consistently show that while US Navy submarines have experienced serious accidents requiring extensive repairs and causing casualties, none have been confirmed as total losses in recent years.
