Sources Sought DEPT OF DEFENSE is seeking prospective vendors for an engineering services effort regarding the B-2 Data Entry Panel (DEP). The B-2 DEP is a flight safety critical unit used for avionics monitoring and control capabilities. The unit is designed for nuclear environment operations and is in critical need of obsolescence resolution. The purpose of this effort includes the design, build, and qualification of support equipment for test and manufacturing of the DEP, as well as updating the Technical Data Package (TDP) to enable future procurement and repair. Potential vendors must be capable of evaluating proposed alternatives for long-term sustainment, maintaining LRU form, fit, and function, and meeting all current B-2 DEP P-Spec requirements. Northrop Grumman is currently the only known source with qualifications for this effort.
