We are proud to be part of the new United States Navy's DDG1000 Zumwalt Class multimission destroyer program in addition to our current DDG51 Arleigh Burke Class of destroyers. In support of this advanced technology destroyer, Janseneering was awarded a multiyear contract for the design, engineering, tooling, parts fabrication and the machining jigs/holding fixtures of the underwater propeller strut/shaft composite fairwater fairings. The DDG1000, like the DDG51 fairwaters, were designed using Finite Element Analysis to insure they will be strong enough to withstand any foreseen exposure to battlefield conditions.

The 3D CAD files were imported to our Surfcam machining software at which point the tooling paths were developed. The "plugs" representing the outside surface were machined on our 5 axis CNC machines. Production moulds were fabricated and mounted to trunnions so that the moulds can be rotated to facilitate the lamination process. The new class as well as the previous class of fairwaters are produced from e-glass reinforcements and a matrix utilizing the Vacuum Assisted Resin Transfer Molding (VARTM) method. All trimming and machining of the laminated fairwaters are done on our 5 axis CNC machines.
