U.S. Navy (NAVSEA)/Submarine Additive Manufacturing

Navy reported placing ~120 additive-manufactured parts in development, installing 20 in production submarines, and eliminating 1,400+ delay days. Advanced manufacturing reduces lead times 70%, overcoming casting and forging bottlenecks.

• ~120 parts placed in development, 20 installed in production submarines over one year.
• Lead times reduced up to 70% vs. traditional casting and forging methods.
• Eliminates bottlenecks constraining submarine production capacity.
