WHAT IS A PEO?

The acronym “PEO” can stand for either Program Executive Office or Program Executive Officer. A PEO plays a key role in the US military acquisition process and the organization or officer may be responsible for a specific program or platform (such as PEO JSF, which focuses on the Joint Strike Fighter), or for an entire portfolio of similar programs (such as PEO Ships or PEO Soldier). Some examples of PEOs are listed below, organized by Service.
