The Department of Defense, specifically the Naval Air Warfare Center Aircraft Division (NAWCAD), is conducting market research to identify potential sources for the procurement of rack-mounted Analog Voltage Output Stimulus instruments as part of the Engine Test Instrumentation Replacement System (ETIRS). The instruments must meet specific performance and environmental requirements, including compliance with military standards for operation in various conditions, and may be Commercial Off the Shelf (COTS) or Modified COTS products. Interested vendors are invited to submit their capabilities, past performance, and technical documentation by December 16, 2024, to the designated contacts, Justin Panecki and Terrence Shearer, with further details available upon request for U.S. DoD contractors who provide the necessary documentation.
