Delta Sigma

Delta Sigma began operations in January 1990 in Hesperia, California, providing support to the stealth F-117 Nighthawk and emerging F-22 Raptor programs. Delta Sigma played a pivotal role in ensuring that both aircraft fleets maintained the lowest possible radar cross section while in operation. Delta Sigma's custom pylons, rotators, and RCS chamber designs were instrumental in the production of these aircraft programs.
