1.3 Requirement.
The MEP-PU-810 Power Unit (the power generation part of the Deployable Power Generation & Distribution System) was first fielded in Fiscal Year (FY) 2021 and IAW Assistant Secretary of the Army (Acquisition, Logistics and Technology) (ASA(ALT))
economic useful life (EUL) policy has an estimated EUL of 17-25 years. This will lead to hardware and software obsolescence challenges in the future. These sustainment and cybersecurity challenges must be addressed to maintain mission readiness.
The DPGDS PU Recapitalization, MEP-PU-810D effort, is nearing the end of its production contract. DPGDS software components are currently supported for the duration of this contract. At the end of the current contract, the MEP-PU-810C/D will transition to sustainment (T2S) and be transferred to the U.S. Army Communications-Electronics Command, Integrated Logistics Support Center (ILSC). Software sustainment, however, will remain with PdL LPS. IAW ASA(ALT) Policy, PdL LPS is required to sustain the software for the lifecycle of the system.
There is a potential need to acquire contractor services to manage, maintain, and secure the software for the MEP-PU-810D fleet. This requirement encompasses program management, systems security engineering, secure software development, software assurance, Supply Chain Risk Management (SCRM), and continuous cybersecurity and vulnerability management for the DPGDS software (Dief, Easy Reg, Jal Test, Webasto, Basler and Beijer).
