One of a few key individuals in the United States military acquisition process
A program executive officer, or PEO, is one of a few key individuals in the United States militaryacquisition process. Shown by the examples below, a program executive officer may be responsible for a specific program (e.g., the Joint Strike Fighter), or for an entire portfolio of similar programs (e.g., the Navy PEO for aircraft carriers).
Army: The direct reports of the Army Acquisition Executive are program executive officers for the respective program executive offices (PEOs)[1]
The current program executive officers include (but may not be limited to):
Command, Control, Communications, and Network – BG Shane Taylor (Acting), PEO C3N[1] (formerly PEO Command, Control and Communications-Tactical, or PEO C3T)[26][27][28]Aberdeen Proving Ground, MD
Enterprise – Mr. William Hepworth, PEO Enterprise[1] (formerly PEO Enterprise Information Systems, or PEO EIS) Fort Belvoir, VA
In October 2023, changes to three PEOs' missions occurred. The restructure transferred network-related areas previously under multiple PEOs', to instead be under one PEO (for example, UAVs were studied by PEO Aviation and PEO Soldier). The network-related areas of interest were supplied by three PEOs, including: Intelligence, Electronic Warfare and Sensors (IEW&S); Command, Control and Communications-Tactical (C3T); and Enterprise Information Systems (EIS). The PEO for Intelligence, Electronic Warfare and Sensors (IEW&S) gained the responsibility for all cyber operations. The responsibility for tactical and enterprise network elements was assigned to PEO Command, Control and Communications-Tactical (PEO C3T).[clarification needed] As part of the transfer, two PMs from PEO EIS were transferred to PEO IEW&S and PEO C3T. The realignment did not affect any Army positions or contracts.[38][39]
