The APEX program will design, build, and test classified submarine propulsor technology. The BAA seeks full proposals for Phase 1 (Phase 1A Base, Phase 1B Option, and Phase 1C Option) and a rough order of magnitude (ROM) cost estimate for Phase 2 (Phase 2A and Phase 2B). Phase 1A focuses on design space exploration and concept design activities concluding with a Conceptual Design Review (CoDR). Phase 1B continues the maturation of selected concept(s) and concludes with a Preliminary Design Review (PDR). Phase 1C is an opportunity for risk reduction efforts in advance of Phase 2. Through an updated BAA during Phase 1B with limited competition among Phase 1B performers, a single performer and single concept may be selected for Phase 2 of the program where a detailed design will be finalized and a quarter-scale demonstration unit will be built and tested.
