The Department of Defense, through the Naval Air Warfare Center Aircraft Division (NAWCAD), is conducting market research to identify potential sources for rack-mounted Analog Discrete Input Measurement instruments for the Engine Test Instrumentation Replacement System (ETIRS). The instruments must meet specific performance and environmental requirements, including compliance with military standards for operational conditions and software control through standardized APIs. This Request for Information (RFI) aims to gather vendor capabilities, past performance data, and pricing details, with responses due by December 16th at 4 PM EST. Interested vendors should contact Paras Patel at paras.d.patel.civ@us.navy.mil for further information and to request the performance specification, which is export-controlled.
