Project and Engineering Support Services II (PESS II) Extension

The National Aeronautics and Space Administration (NASA) has issued a Justification and Approval (J&A) for a contract extension to Millennium Engineering and Integration Services (MEIS) under contract 80ARC021D0001. This extension for Project and Engineering Support Services II (PESS II) includes a twelve-month base period and two six-month option periods, extending the performance period from April 1, 2026, through March 31, 2028. The underlying agreement is a cost-plus-fixed-fee (CPFF) hybrid contract featuring firm-fixed-price (FFP) line items for phase-in and CPFF line items for management, core technical services, and indefinite delivery/indefinite quantity (IDIQ) requirements.

The PESS II contract provides engineering support services at NASA Ames Research Center (ARC) to facilitate mission goals, including the design of new mission concepts and the development and demonstration of engineering products. These services support the operation of various research facilities, such as aerospace and aeronautics labs, wind tunnels, arc jets, simulators, and flight operations centers. The work falls under NAICS 541715 for Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) and PSC AR11 for Space R&D Services; Space Flight, Research and Supporting Activities; Basic Research.

This action was published on April 6, 2026, and includes one attachment, the redacted Justification for Other than Full and Open Competition (JOFOC). The primary point of contact for this requirement is Noor Khazendar. Performance supports critical state-of-the-art infrastructure including fabrication facilities, ballistic ranges, and specialized testing chambers at NASA ARC.
