Identify, develop, evaluate, and demonstrate suitable manufacturing techniques for titanium naval components that will reduce weight on the CVN-21 class of aircraft carriers and increase the depth of shipyard experience with titanium components.
The weight of the CVN-78 must be significantly reduced to meet requirements established for the CVN-21 class of aircraft carriers. Titanium components would provide significant weight savings over current steel structures.
The goal of Phase I was to identify candidate components, select demonstration component(s), evaluate application and manufacturing options, make go / no-go decisions on subsequent phases, and assess the overall benefits of the project. During Phase II, selected titanium component(s) were manufactured by domestic titanium suppliers and evaluated. Phase III addressed ship production using the demonstration component(s) produced in Phase II. In addition, the installation and repair requirements for the ship manufacturer were assessed. The installation and repair procedures for the component(s) will be field tested at Northrop Grumman Newport News (NGNN).
The expected benefits from an increased use of titanium on aircraft carriers are reduced weight, lowered center of gravity, increased loading capacity, reduced magnetic signature, reduced maintenance, and decreased life-cycle costs.
Business case did not support execution of Phase II.
