FALLS CHURCH, Va. - March 18, 2026 - Parsons Corporation has achieved a landmark feat in naval technology, successfully 3D printing a hull for a U.S. Navy ship. This breakthrough, announced today, signifies a paradigm shift in shipbuilding, promising faster, more flexible, and potentially more affordable construction methods for the nation's fleet.

The project, spearheaded by Parsons in collaboration with the Navy and undisclosed industry partners, represents a culmination of years of research and development in additive manufacturing - more commonly known as 3D printing - applied to large-scale maritime engineering. While 3D printing has become commonplace in prototyping and creating smaller components, constructing an entire ship hull with this technology was previously considered a significant technical hurdle.

"This is a pivotal moment for the U.S. Navy and for Parsons," stated Leny Brito, Parsons' Senior Vice President and General Manager of Ship and Maritime Systems. "We are thrilled to be leading the way in integrating this groundbreaking technology into naval shipbuilding. This program demonstrates our commitment to innovation and our dedication to delivering cutting-edge solutions for our customers."

Beyond Traditional Shipbuilding: The Advantages of Additive Manufacturing

Traditional shipbuilding relies heavily on welding together large steel plates, a process that is both time-consuming and labor-intensive. Additive manufacturing bypasses many of these limitations. By depositing layers of metal - in this case, a specialized naval-grade alloy - the hull is built up directly from a digital design. This not only reduces the need for extensive welding but also allows for greater design complexity and customization.

Experts predict several key benefits will emerge from adopting 3D printing in naval construction:

• Reduced Production Time: The ability to build components layer by layer drastically shortens manufacturing timelines. Estimates suggest potential reductions in hull construction time by as much as 50%, allowing the Navy to rapidly deploy new vessels.
• Design Flexibility: Additive manufacturing enables the creation of complex geometries and integrated features that would be difficult or impossible to achieve with traditional methods. This allows for optimized hull designs, improving hydrodynamic efficiency and potentially reducing drag.
• Cost Savings: While the initial investment in 3D printing infrastructure is significant, the long-term cost savings are substantial. Reduced labor, material waste, and tooling costs contribute to a lower overall price per vessel.
• Supply Chain Resilience: 3D printing allows for on-demand manufacturing of components, reducing reliance on complex global supply chains and mitigating disruptions caused by geopolitical events or natural disasters.
• Enhanced Customization: Each ship can be uniquely tailored to its specific mission requirements, optimizing performance and capability without incurring substantial cost penalties.

Technical Challenges and the Path Forward

Successfully 3D printing a ship hull is not without its challenges. Scaling up the technology to accommodate the massive size and structural requirements of a naval vessel demands advanced materials science, precise robotic control, and rigorous quality assurance protocols. Parsons' team leveraged their extensive expertise in these areas to overcome these obstacles. The company used advanced metal additive manufacturing techniques, likely involving either Wire Arc Additive Manufacturing (WAAM) or Directed Energy Deposition (DED), to build up the hull in layers. Both techniques utilize welding wire or metal powder fed into a molten pool created by a laser or electron beam.

"Additive manufacturing is a game changer for naval shipbuilding, and Parsons is proud to be at the forefront of this revolution," Brito added.

The current achievement represents a significant proof of concept. The printed hull is expected to undergo rigorous testing and evaluation to assess its structural integrity, durability, and resistance to harsh marine environments. Parsons and the Navy are already planning follow-on projects to build larger and more complex ship components, and eventually, entire vessels.

Implications for the Future of Naval Power

The implications of this breakthrough extend far beyond cost savings and efficiency gains. 3D printing empowers the Navy to rapidly innovate and adapt to evolving threats. It allows for the quick creation of specialized vessels tailored to specific missions, enhancing strategic flexibility. Furthermore, the technology could enable the construction of forward-deployed manufacturing facilities, allowing the Navy to build and repair ships closer to the point of need, reducing logistical challenges.

The successful 3D printing of a ship hull isn't just a technological achievement; it's a strategic imperative for maintaining U.S. naval dominance in the 21st century. As other nations invest in additive manufacturing capabilities, the U.S. Navy's leadership in this field will be crucial for preserving its technological edge and ensuring its continued ability to project power around the globe.
