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 equipment design and operational capabilities in shipboard environments. Interested vendors are required to demonstrate their capability to manufacture Commercial Off the Shelf (COTS) or Modified COTS instruments, provide documentation of past performance, and submit a response by December 16th at 4 PM EST, including their company details and any proprietary information. For further inquiries, vendors can contact Paras Patel at paras.d.patel.civ@us.navy.mil or Terrence Shearer at terrence.d.shearer.civ@us.navy.mil.
