Newport News Shipbuilding and GDEB are integrating 3D printing into the construction process of Virginia-class nuclear-powered submarines that will receive up to 40 Tomahawk cruise missiles

Newport News Shipbuilding and General Dynamics Electric Boat (GDEB) have agreed to integrate 3D printing into the construction process of Virginia-class nuclear-powered submarines. This will expedite the transfer of the submarines to the US Navy's fleet.

Here's What We Know

Shipbuilders want to integrate additive manufacturing technologies, believing it will have a positive impact on the pace of construction of nuclear submarines. It is believed that creating critical critical components through 3D printing will speed up deliveries.

Newport News Shipbuilding and GDEB, in conjunction with supplier AMMCON, have already tested this approach. They were able to create a test model, proof of concept and assemble the drainage system for the Virginia-class nuclear submarine Oklahoma (SSN 802). AMMCON provided final machining and assembly prior to installation.

Newport News Shipbuilding and GDEB currently have orders for Block IV and Block V level submarines. The Block V modification is characterised by the Virginia Payload Module (VPM). It increases the length of the submarine by 25 metres and allows the installation of 40 instead of 12 Tomahawk cruise missiles. In the future, Virginia class submarines will receive hypersonic weapons.
