Interested sources should submit capability information by email, including company/CAGE code data, a technical point of contact, questionnaire responses, drawings or test results, prior government/commercial contract experience, data rights, engineering qualifications, obsolescence management approach, delivery capability, and ability to meet the Government’s spot-buy and fixed-quantity preferences.
