Despite ongoing Science and Technology (S&T) efforts by Government and industry, current APS are inadequate in technical maturity and do not currently meet desired PM requirements. Systems are not configurable for commonality across the vehicle fleet, tailorable to system needs, and ultimately lack a sufficient transitional Technology Readiness Level (TRL). These proprietary systems restrict the Government’s understanding of capabilities and function, and in turn prohibit tailoring systems to meet Size, Weight, Performance, Cooling (SWaP-C), and cost needs. APS modularity has never been pursued and interdependence of system components and safety concerns present significant challenges. APS point designs have been demonstrated, but none are currently fielded by the US.
