Lockheed Martin Rotary and Mission Systems has a rich history of integrating combat systems into naval ships and buildings. The integration of complex radar and support systems into modern war-fighting entities demands the use of a unique set of design and simulation tools to verify and optimize engineering designs before production begins. After the combat system is in the field, it is important to equip the warfighter with informative training and maintenance systems. The goal is to keep the combat system fully operational at all times. GPU technologies such as OpenGL, CUDA, OptiX, and Iray, along with virtual reality and augmented reality, make these unique design and maintenance environments possible. These design practices are being examined in the Surface Navy Innovation Center through dedicated research for domestic and international combat system integration and maintenance.
