In an era where cutting-edge technology can make the difference between success and failure, the United States Navy is leading the way in embracing 3D printing, or additive manufacturing, to enhance the production and maintenance of its submarines.

Rear Admiral Jonathan Rucker recently emphasized the pivotal role of additive manufacturing during a House Armed Services Subcommittee hearing.

This groundbreaking approach is revolutionizing submarine construction, ensuring timely delivery, and bolstering the Navy’s capacity to maintain its fleet.

The Need

The US Navy’s ambitious goals include building one Columbia-class and two Virginia-class submarines annually.

To achieve this, they seek additional funding and authority from Congress, with the White House proposing $3.4 billion in supplemental funding.

A significant portion, around $2 billion, is earmarked to support the submarine industrial base, including the development of technologies such as additive manufacturing.

The rationale behind this push for additive manufacturing is clear – the Navy is struggling to obtain critical parts on time, and shipyards are striving to avert further production delays. The service not only aims to prevent delays but also to increase submarine production.

With their expanded objectives and the need for rapid innovation, the importance of additive manufacturing in submarine construction cannot be overstated.
