The DLA mandate for SigNature DNA will be implemented in a staged fashion, to ensure a smooth transition for the industry providers of microcircuits falling into FSC 5962, as noted by DLA. In the first stage, already accomplished and consistent with the mandate, SigNature DNA is on the microchips produced in the DLA's Generalized Emulation of Microcircuits (GEM) program.
Watch out for APDN!
