The United States Navy is canceling a $3 billion overhaul of the USS Boise, a Los Angeles-class attack submarine, due to rising costs and limited resources. The decision comes as the Navy faces increasing pressure to expand and maintain its fleet amid competition with China, which has built the world's largest navy by number of ships. The Los Angeles class submarine had consumed roughly $800 million and would require another $1.9 billion to complete, despite offering only about 20% of its remaining service life. The Navy plans to redirect funding and skilled labor towards building and delivering newer Virginia- and Columbia-class submarines as part of a broader effort to accelerate ship production and overhaul troubled acquisition programs. The move comes as Congress continues to address the need to speed up shipbuilding and submarine production to meet rising global demands.
